Many different appliances can be used to heat a house, including boilers, water heaters, heat pumps, and wood stoves. These devices are connected to ducts that deliver heated air to registers throughout the house. In Europe, where furnaces are almost unheard of, most homes are heated by a boiler that distributes heat through hot-water pipes.
Even though the smallest available furnaces are often oversized for a high-performance home — a problem I addressed in a 2009 article, Heating a Tight, Well-Insulated House — furnaces still have virtues that are hard to ignore. Furnace efficiency is usually calculated using a laboratory procedure that measures an appliance’s “annual fuel utilization efficiency,” or AFUE.
AFUE can be calculated for boilers as well as furnaces, and is used for appliances that burn many different types of fuel. It is technically difficult to manufacture a furnace with an efficiency between 83% and 89%, so none are available in that range.
High-efficiency furnaces (also called condensing furnaces) have AFUE ratings that range from 90% to about 97%. Condensing furnaces are power-vented, so they include at least two fans: an air-handler fan that distributes warm air through the home’s ductwork, and a power-vent fan to move exhaust gases through the flue pipe.
Most, but not all, condensing furnaces are “sealed-combustion” furnaces — meaning the burners pull outside air into the combustion chamber through plastic ducts to feed the fire’s needs. Energy advice columnists routinely advise owners of vacation homes to turn down their thermostats when the homes are unoccupied. The LBNL experts responded, “For cold-climate homes, turning the heat off (or at least way down) while away is a natural starting point. As it turns out, homeowners following this advice are not only at risk of damaging their furnace; they are at risk of voiding their furnace warranty.
If you read the fine print on the installation instructions for Carrier condensing furnaces, you'll find this statement: “This furnace is designed for continuous return-air minimum temperature of 60°F db [dry bulb] or intermittent operation down to 55°F db such as when used with a night setback thermometer [thermostat]. Intrigued, I contacted the Carrier Corporation and asked whether setting one’s thermostat to 50°F would void the warranty on a Carrier condensing furnace.
The bottom line: condensing furnaces are more efficient than non-condensing furnaces, but their efficiency comes with the added risk that low return-air temperature can contribute to the condensation of corrosive flue gases in the primary heat exchanger.
To make up for the fact that leaky duct systems waste large amounts of energy, HVAC installers usually install oversized furnaces with huge blowers.
In the 1980s, energy-efficiency advocates responded to the nation’s leaky duct crisis by establishing training programs to encourage HVAC installers to seal duct seams. Locating ducts outside of a home’s thermal envelope (for example, in a vented attic or vented crawl space). Using framing cavities like stud bays or panned joist bays instead of ducts to move supply air or return air.
The best way to design a duct system is to follow the Manual D method developed by the Air Conditioning Contractors of America (ACCA). Unfortunately, most HVAC contractors install systems without performing Manual J and Manual D calculations.
To help educate yourself on the elements of duct system design, and to double-check the expertise of your HVAC contractor, you may want to learn a simplified duct design method like the one outlined in “Trouble-Free Forced-Air Heat” by Gary Bailey. Bailey’s article includes a chart showing the cfm capacity and Btuh capacity of different duct sizes.
A standard duct size used to serve individual registers in residential forced-air systems is often 6-inch round galvanized duct, which can deliver 100 cfm and 7,400 Btuh of heat. Traditionally, supply registers were usually located near exterior walls, in an attempt to counteract the chilling effect caused by winter infiltration and the radiational cooling that occurs when warm bodies lose heat to cold window glass. It should go without saying that duct seams should be sealed with mastic and duct systems should be checked for leakage with a Duct BlasterCalibrated air-flow measurement system developed to test the airtightness of forced-air duct systems. Commenting on the research, Philip Fairey, FSEC’s deputy director, noted, “In most cases the units as shipped from the factory contain seams that leak. Locate the furnace in the center of your basement or in a mechanical room near the center of your house. If the house has high-performance windows and a low rate of air leakage, locate supply registers on interior walls. Design a return air system with multiple return air grilles rather than a single central return. Plan for a return air path from every conditioned room back to the furnace’s return air plenum. Clicking around the web a bit more, one can find forum discussions about the need for proper setup, frequent cleaning, and possibly even special fuel for these units.
Fair enough, but wouldn't you still have to locate the return air ducts near exterior walls, which would negate the savings?
Traditionally, supply registers are installed low in heating-dominated climates, and are installed high in cooling-dominated climates. In a tight, well insulated house, the location of the supply registers isn't as critical as it is in an old, leaky house. Again, assuming that you have supply registers with a good throw installed high on interior walls, return grilles can also be located near the interior of the house, with no performance penalties. Choosing the right supply registers is an art unto itself, deserving of a dedicated article. My question has to do with Marc Rosenbaum recent Q&A blog on minisplits, an answer he gave below.
When your heating and cooling loads in a net-zero home are already smaller than the capacity of anything but a single wall-mount ductless minisplit, how do you balance correct sizing with adequate distribution? Answer 3 — Leigha’s question in Comment #17 is a variation of the first question in a climate that will need cooling as well as heating. Having said that, the system you mentioned that incorporates a wall cassette for the main space, and a ducted unit for the bedrooms would be a step up in occupant satisfaction for many people, because the bedrooms are now able to have their own setpoint.
We built our tight home this last year and have a gas fired hydronic hot air system supplemented with solar thermal.
In retrospect I think we would have been better off with 3 minisplits but we got the solar thermal system and gas furnace at no cost by participating in a NYSERDA program to test the effectiveness of adding solar thermal to gas fired hot water systems. Our advice is that if you go with an air system in a tight house you should design the system for zoning unless the house is a very simple single floor open plan home.
You have raised several issues in your discussion of minisplits versus conventional ducted forced-air systems. If a customer wants consistent temperatures from room to room, even when the doors are closed, then a well designed, well installed ducted forced-air system probably makes more sense than a single ductless minisplit in the living room.

Radiant heating and radiant cooling systems are different from typical HVAC systems because they heat or cool surfaces rather than air. Radiant systems can save large amounts of energy while also providing better comfort, depending on the building and the climate. Spaces with large air volumes and large amounts of unavoidable infiltration, such as loading docks and warehouses, are especially good building programs for radiant floor heating because heating the air would be inefficient. Even in more typical applications, radiant systems are more efficient than forced air heating or cooling because there are no duct losses.
Modern radiant heating systems are generally heated floors, to take advantage of convective air heating as well as mean radiant temperature. Radiant floors can be directly heated by electric resistance heating, or heated by water in a circulating loop. Regardless of how the floor is heated, the heating system can connect to a large thermal mass or not. Thermal mass is useful for radiant floors when the heat is generated at a different time of day than it is needed for comfort. Radiant floors without thermal mass are useful for faster response times, when the mean radiant temperature is controlled by a thermostat. Radiant cooling systems are generally chilled ceiling beams or panels, to take advantage of convective air cooling as well as mean radiant temperature.
Convection is more important for radiant ceiling panels and beams because, unlike radiant floors, no one will touch these surfaces. Radiant panels and beams usually do not cover entire ceilings, so they have smaller areas than radiant floor systems.
Chilled panels and beams can be less obtrusive when they perform other functions at the same time--for instance, panels can also integrate acoustic damping, and beams can integrate lighting fixtures or other services. Autodesk is committed to helping designers and engineers create a future where we all live well and within the limits of our planet. Solar power facts tells us that we must adopt and use as much as we can this energy if we want to protect the earth and save the planet. The sun is virtually inexhaustible source of energy that can guarantee continuous pumping if we know how to use it. People since ancient times understood the benefits and importance of the Sun and its energy. These days we use solar energy mostly for electricity generation, and this production of electricity from sunlight is made in two ways: indirectly, by heating a liquid or directly with photovoltaic cells.
Photovoltaic cells are semiconductor devices that directly convert sunlight energy into electricity. In terms of producing electricity from sunlight, it is done with concentrated solar energy, where there are four concepts: parabolic system, Frenel’s reflectors, reflective plate system and solar tower. The problem with focusing is the large space required for the plant, but it is handled so that the power plant for example can be in the desert. The sun produces energy for five billion years, and according to current estimates of the energy production will continue for another five billion years. Secondary sources of energy powered by solar energy, like wind power, wave power, biomass and hydro power, make the most of renewable energy sources on earth. At night and on cloudy days solar energy is not fully available and we need energy storage systems that are filled when the energy is available. Leonardo Da Vinci  (1452 – 1519) planned industrial use of solar energy using a concave mirror, which directed the rays on solar water heaters. Solar energy is environmentally friendly, clean, and renewable without any harmful pollutants and emissions in faze of production.


Economical because it saves our money and after initial investment the energy we get is absolutely FREE.
Climate of a place and geographic location of place where you live can be a factor of advantage or disadvantage in using solar power energy. The heating that I have installed at the moment is the traditional, central heating system.
I didn’t upgrade to a new central heating system though, I know some of you will be assuming I did.

I have been looking at underfloor heating for my home ever since I found out how good underfloor heating is compared to it’s rival, central heating systems. This heating does its job, I mean it does heat up my home to a comfortable temperature but there are certain things I have noticed about central heating over the many years I have been living with it in my home and I am sure most of you may have experienced these factors too.

When it comes to heating up your home there are many ways you can achieve a comfortable heat temperature in your home however two of the main ways in which you can heat up your home is by a central heating system and underfloor heating.
A central heating system provides heat form a position of your choice and spreads out heat from a focal point across the room.

Homeowners in virtually every region of the United States are enjoying a high level of comfort and significantly reducing their energy use today with geothermal heating and cooling. Owners of geothermal systems can relax and enjoy high-quality heating and cooling year after year without all the extra expense. The geothermal equipment can be located indoors because there’s no need to exchange heat with the outdoor air. Geo-exchange or geothermal energy systems work differently than conventional heat pumps that use the outdoor air as their heat source or heat sink. The temperature of the ground or groundwater a few feet beneath the Earth’s surface remains relatively constant throughout the year, even though the outdoor air temperature may fluctuate greatly with the change of seasons. Conversely, in summer, the relatively cool ground absorbs a home’s waste heat more readily than the warm outdoor air. Because geothermal or geo-exchange systems heat water so efficiently, many manufacturers today are also offering triple function systems. Once installed, the loop in a geo-exchange or geothermal renewable energy system remains out of sight beneath the Earth’s surface while it works unobtrusively to tap the heating and cooling nature provides.
Today, homeowners in all income brackets can take advantage of the benefits of geothermal power. Visit our Businesses and Services page to contact a local professional for more information. HVAC products that have an Energy Star label meet specific performance and efficiency guidelines that have been created by the Environmental Protection Agency.
The Seasonal Energy Efficiency Ratio or SEER, is a measurement of energy efficiency in air conditioning systems.
The Heating Seasonal Performance Factor or HSPF, is a unit of measure utilized to rate heat pumps by their levels of heating efficiency. Annual Fuel Utilization Efficiency or AFUE, is the measurement of furnace heating efficiency. You may qualify if you have purchased an energy-efficient product that meets certain criteria, but not all Energy Star labeled products qualify for a tax credit. We will make sure to tailor all of our work and services regarding heating to your exact needs and specifications. We have the skills and the qualified staff to undertake any project, no matter big or small. Different types of furnaces are manufactured to burn a variety of fuels, including natural gas, propane, oil, and firewood. Unlike Europeans, however, most Americans insist on central air conditioning in their homes. They are inexpensive, widely available, and easily serviced by local HVAC(Heating, ventilation, and air conditioning).
This calculation accounts for heat losses up the chimney, heat losses through the appliance jacket, and heat losses due to on-and-off cycling, but it doesn’t account for electricity use (fan energy use) or heat lost through the distribution system (ductwork). The reason that you can no longer buy a low-efficiency furnace is that the federal government now requires residential gas-fired furnaces to have a minimum efficiency of 80%. The line between mid-efficiency and high-efficiency furnaces is not arbitrary, but marks the division between appliances with distinct operating characteristics. Furnaces with "in-between" efficiency have sporadic condensation of flue gases, and this condensation causes corrosion problems.
These furnaces have a secondary heat exchangerDevice that transfers heat from one material or medium to another. However, the venting system for a high-efficiency furnace may cost less than the chimney required for a mid-efficiency furnace. If the furnace is rated with an output of 60,000 Btuh, that is the furnace’s output whenever it is running. Most of the time, these furnaces operate at a lower Btuh output; the higher output is only needed on the coldest days of the year. They include an automatic fuel valve that varies the amount of fuel delivered to the burner.
While it’s fairly easy to design a gas valve which varies the amount of fuel delivered to the burner, oil burners have a nozzle that is optimized for a single firing rate at a fixed Btuh output. After three decades of training, these programs are beginning to bear fruit in some areas of the U.S.
The use of Manual D presupposes that you have already performed room-by-room heating loadRate at which heat must be added to a space to maintain a desired temperature.
While the method described in Bailey’s article is no substitute for the Manual D design process, it is probably better than the method used by many HVAC contractors. The chart assumes that the maximum distance from the furnace to a supply register is 60 feet; this maximum allowable duct length must be decreased to account for each elbow in the duct run. These dampers are adjusted as part of the commissioningProcess of testing a home after a construction or renovation project to ensure that all of the home's systems are operating correctly and at maximum efficiency. If your duct system is undersized, air flow will be constricted and the furnace may not be able to remove heat fast enough to prevent damage to the heat exchanger. Most residential HVAC systems have undersized return ducts; when in doubt, make them bigger.
The corrugations in flex ducts cause turbulence that reduces airflow through the duct; moreover, flex duct is hard to keep straight and well supported. If you are building a tight house with thick insulation and high-quality windows, however, it’s possible to install supply registers on interior walls. But if your furnace is located in a garage or vented attic — a bad idea, by the way — leaky furnaces waste energy. If flex duct is installed, support it with an adequate number of hangers, and make sure the duct runs aren’t twisted, crushed, or pinched. Before specifying a furnace for your next project, however, remember that other options exist.
While I've never seen one 'in the wild' (and I wonder how much cleaning they require) you can find them.
I was just standing next to a Carrier multistage unit yesterday in 9 degree temperatures, it was running along just fine.
I have edited my article to reflect the information you provided on oil-fired condensing furnaces. Studies have shown that either high returns or low returns can work well with either type of supply system.
This is a great article and explains many of the problems I have noticed when repairing faulty duct work (especially things like running ducts through I-joists with sheet metal). Seems the issue can be having to leave room doors open compromising mommy and daddy’s privacy, etc, and whole house sizing(BTU’s through walls, etc) he presented some calculations on I appreciate but would not want to reply on. A ducted unit with the temperature sensor built into the air handler (the stock setup) averages the return temperature from the bedrooms to decide how much heating or cooling to provide. With a strongly passive solar design, the whole-house ducted system can serve to redistribute air from the warmer side of the house to the bedrooms. Poorly designed and leaky duct systems are responsible for tremendous quantities of wasted energy.
You're right that it is difficult to maintain even temperatures if a two-story house is heated and cooled with a single-zone forced-air HVAC system. For areas in the New England states where oil is the primary fuel for heating, ThermoPride branded furnaces (specifically the OHC95 & OH6 2-Stage) could be the best options for homeowners looking to conserve energy.
He built his first passive solar house in northern Vermont in 1974, and has lived off the grid since 1975.
Also, in heating applications, heat is delivered low in the room where occupants are, rather than at the ceiling from overhead ducts.
The solar power facts speaks that this huge, endless energy can be used for all human kind on many different ways as the main renewable energy source. Energy that the sun shines on earth is 15 percent larger than it needs to man, but unfortunately today very small part we can use.
Not coincidentally in most ancient cultures in the world supreme deity is the Sun or any of his performance.
In this way we get electricity, but water is heated by passing through the collector itself. Due to the high concentration of solar rays, the liquid rapidly is heated to high temperature. Solar energy can be stored in different forms, but most popular are the conversion of thermal energy, storage in batteries and accumulators. What I have noticed is that the rooms can suffer from cold spots and I tend to find myself running to the central heating system to stay warm because I don’t feel like central heating ca distribute heat efficiently. This heating system runs on electricity so it saves you money as well as heating up your flooring and spreading the heat evenly across the room.
With geothermal or geo-exchange, there’s no need to create heat, hence no need for chemical combustion. These systems don’t have to work as hard (which means they use less energy) because they draw heat from a source whose temperature is constant.
At a depth of approximately six feet, for example, the temperature of soil in most of the world’s regions remains stable between 45? and 70°.
Studies show that approximately 70 percent of the energy used in a geothermal heating and cooling system is renewable energy from the ground. This can be highly economical, especially if the home already has a geo-exchange system, hence a ground loop, in place. What’s more, some electric utilities around the nation now have incentive programs and low-interest financing programs which makes geothermal or geo-exchange even more affordable.


Is installing a geothermal heating and cooling system a viable option for Mesquite residents? Each zoned area has its own thermostat, which allows the system to send hot or cold air to just the rooms that need it.
If your HVAC equipment in your Mesquite home is not working correctly or is more than 10 years old, it is recommended that you upgrade to equipment with an Energy Star label. This rating system allows consumers to compare the operating costs between different air conditioning systems.
Is it really necessary to schedule preseason check-ups for my air conditioning and heating systems? It is recommended that you plan ahead, especially right before a great change in temperature. These filters are able to eliminate more allergens and particles than conventional air filters.
If I purchase a new heating or cooling system, do I qualify for federal energy savings tax credits and utility company rebates? You can program this thermostat to automatically adjust the temperature of your home depending upon the temperature outside. We hold relevant qualifications for Gas Safe and NICEIC, and are proud members of Checkatrade.
Furnaces should be installed in your basement or a mechanical room near the center of your house — not in a vented attic, vented crawl space, or garage. Mid-efficiency furnaces are designed to keep flue gases hot enough to avoid any condensation of flue-gas moisture, while high-efficiency furnaces deliberately encourage the condensation of flue-gas moisture.
Furnaces with an efficiency of 90% or more wring so much heat out of the flue gases that the furnace exhaust can be vented through PVC pipe, a material which is more resistant to corrosive condensate than the stainless-steel vent pipe that would have to be used for the hotter flue gases that would occur in a furnace with an efficiency in the tricky 83% to 89% range. An air-to-air heat exchanger, or heat-recovery ventilator, transfers heat from one airstream to another. According to some HVAC specialists, oil-fired condensing furnaces require frequent cleaning. Many modulating furnaces also include a variable-speed blower motor (usually an electronically commutated motor, or ECM) which (like the automatic fuel valve) ramps up and down in response to heating demand. In many areas of the country, contractors still install ductwork in vented crawl spaces or vented attics; since these locations are outside of a home’s conditioned envelope, the conditioned air that escapes from leaky ductwork in these locations is gone for good. Unfortunately, the gospel of airtight ductwork hasn’t reached every corner of the country, and many HVAC contractors are still installing ductwork the way their grandfathers did in 1964. For maximum efficiency, ducts should be as straight and as short as possible, with a minimum of elbows.
This strategy results in shorter duct runs that operate more efficiently than longer ducts extending to a building’s exterior walls. In a study conducted by the Florida Solar Energy Center (FSEC), 69 furnaces and air handlers were measured for leakage. An increasing number of high-performance homes are heated and cooled with two or three ductless minisplit heat pumps. When I last did the math on a heat pump, it was less expensive to run than a propane furnace. With the bedrooms to the north in this very well insulated passive solar house, I’m assuming that they don’t have a ton of glazing, which in this case drives heat gains from the sun, as well as heat loss.
Anyone interested in achieving very low energy bills should consider whether a ductless minisplit or a ducted minisplit might satisfy their needs.
I agree with your conclusion that a few ductless minisplits would have worked better for you than the system that was installed. In 1980, Holladay bought his first photovoltaic(PV) Generation of electricity directly from sunlight. The fact that every single hour the Sun beams on Earth energy enough to satisfy global energy needs for an entire year speaks clearly how big this source of energy is.
People benefits from its energy in the building of homes (for more light and heat), food processing (drying), and in war (it is known that Alexander of Macedonia always fought his battles at noon with the sun behind his army, or heat ray from Archimedes, who by directing mirrors managed to burn the sails of ships that siege Syracuse). When these cells are hit with sunlight, becomes reaction which triggers electrons to loose from atoms. Then, this liquid is used for steam, which still carries the turbine to generate electricity, similar to the thermal plants. The destruction of forests in the time of Da Vinci was also big because they were main fuel for humanity. Recently my central heating system has been struggling to keep itself at a comfortable room temperature. I have also noticed that central heating costs a lot of money and can be a dent on your income in the cold harsh winters.
What makes underfloor heating miles better than its rival, central heating, is that underfloor heating provides you with warm flooring and it will distribute heat evenly across your room. Because this method does not allow the heat to spread evenly and you will suffer from over heated spots and cold spots too while spending a lot of money.
Instead, the Earth’s natural heat is collected in winter through a series of pipes, called a loop, installed below the surface of the ground or submersed in a pond or lake. Geo-exchange or geothermal power systems provide cooling in the same way that a refrigerator keeps its contents cool–by draw.
This is why well water drawn from below ground tastes so cool even on the hottest summer days. This is also why geo-exchange systems encounter no difficulty blowing comfortably warm air through a home’s ventilation system, even when the outdoor air temperature is extremely cold.
The remainder is clean, electrical energy which is employed to concentrate heat and transport it from one location to another. A conventional system with only one thermostat works well for one room, but it is not able to determine the temperatures in the other rooms in your home.
This rating ranges from 80% to over 90% AFUE now, but many Texas homeowners have old equipment and these units are as low as 50% efficient abd should be replaced even if they work well.
The best time to discover and deal with air conditioning and furnace repair is before a season ends and a new one begins. To receive your tax credit, Mesquite, TX residents need to file an IRS Form 5695 along with your taxes. You can program it so that when you are away or sleeping, you do not use as much energy and this can decrease your cooling costs by up to 20%. Sadly, this illustration comes from the web site of the Air-Conditioning, Heating, and Refrigeration Institute (AHRI).
Once you have a duct system for cooling, it’s cheaper to install a furnace for winter heating than to install a boiler with a separate distribution system.
A copper-pipe heat exchanger in a solar water-heater tank transfers heat from the heat-transfer fluid circulating through a solar collector to the potable water in the storage tank. Since modulating furnaces can match the heating demand precisely, they provide more even heat than single-speed furnaces which operate with a stop-and-go jerkiness. Whether you choose galvanized ducts or flex ducts, make sure to install enough duct hangers to prevent sagging. A photovoltaic cell has no moving parts; electrons are energized by sunlight and result in current flow. There is nothing bad I can actually say about it, I mean it heats up my flooring, provides me with equally warm room without cold spots and it is a lot cheaper to run. The underfloor heating system is an addition but has a similar purpose with extra benefits. They do the work that ordinarily requires two appliances, a furnace and an air conditioner. In contrast to conventional systems, this can save you 30% to 50% in cooling expenses and 40% to 70% in heating expenses.
Zoning allows for uniform temperature throughout your home and will eliminate hotter or colder rooms. Older systems will likely possess a lower SEER rating (SEER rating of 5) compared to newer systems, which will have a higher rating (SEER rating of 10). If your furnace is more than 10 years old, it will likely have an AFUE rating lower than 80%.
You need to make sure your system is in working order so that it will be ready when you need it. Since a heat pumping system moves heat instead of producing heat, you can save 30% to 40% on your electricity usage. We know that relationships are important and we want to start the conversation and education now, so that when you do need air conditioning repair or furnace repair, you’ll call on us because you have grown to trust our judgment.
Others like “tricking the thermostat with heat from xmas light bulbs or you cell phone ” he suggest to set the min temp , those sort of tactics won’t sell. Inside the housing is a vacuum, in order not to lose heat collected inside (no air, no heat transfer).
The indoor location also means the geothermal or geo-exchange equipment is protected from mechanical breakdowns that could result from exposure to harsh weather. In summer, the ground heats up more slowly than the outside air, transferring heat from the interior out of the house.
This phase change from water vapor to liquid water releases heat, improving the unit’s efficiency. I was trying to avoid changing the heating but I knew I had to so I can heat up my home efficiently and save myself a bit of money in the long term.
One thing I really like about underfloor heating is that it is hidden away form sight and it is safer. Condensing furnaces must be hooked up to a drain that can dispose of the liquid condensate. If so have we just lost the benefits of no ducts, associated duct problems, and installation cost? The tubes are coated with black paint in order to better absorb solar energy, and the base of the casing with white paint or made of metal or sets of reflective material that can efficiently directing light onto the pipes. I noticed some companies offering more and more air handlers so maybe technology is moving quick here and this is a better alternative to the convention HVAC?
The reason for this is that collector actually uses infrared rays of the sun to heat rather than visible light. That’s way collectors can be used in winter or when it is cloudy, with reduced sunlight because infrared light passes easily through obstacles in the atmosphere. Our plan is to have mechanical dampers and thermostats controlling the second floor and the master separately from the living area.
