How efficient is radiant floor heating?
WarmlyYours claims that radiant floor heating is 100 percent efficient because there is no way for heat to be lost, and that means you never have to overheat, which can increase fuel costs by 8 percent. Radiant floor heating is usually installed with a manifold that splits the main line from the boiler into zones that serve individual rooms, and this is another energy-saving benefit. Each zone can have its own thermostat, allowing homeowners to selectively heat the parts of the house they use the most instead of having to heat the entire house to the same temperature. This is a cost-effective bonus for a small family occupying a large house or for people who spend most of their time in specific areas, such as the living room, bedroom and kitchen.
How does forced air heating work?
A forced-air heating system employs either a furnace or heat pump to heat air and circulate it throughout the building through a ductwork system. A not-insignificant portion of this heated air gets lost through leaks in the ductwork, and the warm air that exits the registers tends to rise to the ceiling, where even more is lost through gaps in the home's structure. People tend to spend most of their time on the floor, not the ceiling, so their heads feel warmer than their feet, which is not an ideal situation for those who like to traipse around the house in bare feet.
Is hydronic heating the same as electric heating?
Electric radiant floor heating systems provide the same type of comfortable heat as hydronic systems, but electricity is expensive and ultimately less efficient than heating water with a gas boiler. Also, an electric radiant floor often doesn't get hot enough to heat an entire room, so its best application is for warming floors in particular parts of the house, and you often need a supplemental heat source. A hydronic floor heating system, on the other hand, provides whole-house heating, so if you're thinking of alternatives to furnaces and heat pumps, it's the better candidate.
Is radiant heating more efficient than forced air heating?
If you're wondering whether radiant floor heating systems are more efficient than forced-air heating systems, the answer is almost always yes provided the discussion is about hydronic (hot water) radiant heating and not electric. According to a study from Kansas State University, hydronic radiant floor heating is typically 25 percent more efficient than other forms of home heating, including forced air, and there are several reasons for this. In fact, by making the right installation choices and running a hydronic system with energy savings in mind, homeowners can increase the efficiency even further.
Does water have more energy than air?
By comparison, water can transport 3,500 times more energy than air, which means that much more energy generated by the heat source is available for heating. None of the energy is lost through leaky ductwork, and because it radiates from the floor upward, much less is wasted through structural gaps in the building, and people's feet feel warmer than their heads. Moreover, the entire room is heated uniformly, so there are no cold spots. All in all, homeowners are able to feel comfortable with lower thermostat settings, which can make a big difference in energy savings.
Can you put radiant heat under carpet?
Installing radiant heat under carpeting may work in a small room that is tightly insulated, but it isn't recommended for drafty hallways or rooms with high ceilings.
Is radiant heat quieter than forced air?
In terms of air quality and comfort, radiant systems are cleaner and quieter than forced-air systems. Even though HVAC systems have filters, they still tend to circulate and recirculate pollutants and allergens, particularly if the filters don't get changed regularly, and HVAC equipment is noisy. In-floor radiant heat systems do not circulate allergens, they are quiet and — added bonus — they require no maintenance other than that needed to keep the boiler running smoothly.

What is the best floor covering for radiant heat?
Ceramic tile is the most common and effective floor covering for radiant floor heating, because it conducts heat well and adds thermal storage. Common floor coverings like vinyl and linoleum sheet goods, carpeting, or wood can also be used, but any covering that insulates the floor from the room will decrease the efficiency of the system.
Why is radiant heat better than forced air?
It is more efficient than baseboard heating and usually more efficient than forced-air heating because it eliminates duct losses. People with allergies often prefer radiant heat because it doesn’t distribute allergens like forced air systems can. Hydronic (liquid-based) systems use little electricity, a benefit for homes off the power grid or in areas with high electricity prices. Hydronic systems can use a wide variety of energy sources to heat the liquid, including standard gas- or oil-fired boilers, wood-fired boilers, solar water heaters, or a combination of these sources. For more on the different types of energy sources and heat distribution systems for home heating, explore our Energy Saver 101 infographic on home heating.
What is hydronic radiant floor?
Hydronic (liquid) systems are the most popular and cost-effective radiant heating systems for heating-dominated climates. Hydronic radiant floor systems pump heated water from a boiler through tubing laid in a pattern under the floor. In some systems, controlling the flow of hot water through each tubing loop by using zoning valves or pumps and thermostats regulates room temperatures. The cost of installing a hydronic radiant floor varies by location and depends on the size of the home, the type of installation, the floor covering, remoteness of the site, and the cost of labor.
Why do we use dry floors?
Due to recent innovations in floor technology, so-called "dry" floors, in which the cables or tubing run in an air space beneath the floor, have been gaining in popularity, mainly because a dry floor is faster and less expensive to build. Because dry floors involve heating an air space, the radiant heating system needs to operate at a higher temperature.
Why are radiant panels uncomfortable?

How much power does a radiant heat system use?
They consume from 6 to 12 watts per square foot, which amounts to 600 to 1,200 watts for a 100-square-foot room. The cables can be powered by either a 120- or 240-volt electrical circuit; 120 volts works better for smaller floors, whereas 240 volts is preferable for larger ones. A 240-volt system draws less current (amperage, measured in amps) than a 120-volt system to achieve the same power level, and that makes a difference to the line thermostat that controls the system, which can typically handle a maximum current of 15 amps.
How much does it cost to install a floor mat?
The cost for electric floor mats designed to be installed under flooring vary, but as examples, a 10-square-foot SunTouch mat costs $137, while a 90-square-foot LuxHeat mat costs about $500. Once the mat is installed, operating costs depend on the local rate for electricity, which can vary from 12 cents per kilowatt-hour in Colorado (which is close to the national average) to 21 cents in California. If you pay the Colorado rate, it will cost about 50 cents to provide heating for a two-hour period in the morning and a two-hour period in the evening, or about $15 per month. In California, you'll pay 84 cents per day, or about $25 per month.
What are the components of radiant floor heating?
An electric radiant floor heating system has only three components: heating cable, a temperature sensor and a floor-heating thermostat. Instead of PEX tubing to carry water, an electric radiant heat system uses electrical cables that function like the resistive elements in electric space heaters, although they don't get nearly as hot.
Where does the heating cable go for radiant floor?
Like the PEX pipes for a hydronic system, the heating cable for an electric radiant floor system can go underneath the subfloor or between the subfloor and the floor covering. Most homeowners opt for the latter because putting the cable above the subfloor instead of underneath it makes the heat more readily available, and you end up using less electricity.
What is uniform heating?
Uniform heating: All areas of the floor feel equally warm. Compare this to electric baseboard heaters or room space heaters, which warm the space around them more than the space on the other side of the room.
How much does it cost to heat a mat in Colorado?
Once the mat is installed, operating costs depend on the local rate for electricity, which can vary from 12 cents per kilowatt-hour in Colorado (which is close to the national average) to 21 cents in California.

How much does it cost to run a radiant floor heater?
As a result, the cost to operate an electric radiant floor heating system in a bathroom this size would be $0.22 a day or $6.60 a month. By comparison, it costs about $34.10 a month to run a window air conditioner and $36.50 a month to run a portable heater.
How much electricity does an electric floor heater use?
A typical electric floor heating element produces 15 watts per square foot. When installed in a small 35 square foot bathroom running a total of 8 hours a day, the system would only use 4.2 kWh per day or 128.1 kWh per month. The national average kWh rate is $0.12. As a result, the cost to operate an electric radiant floor heating system in a bathroom this size would be $0.22 a day or $6.60 a month. By comparison, it costs about $34.10 a month to run a window air conditioner and $36.50 a month to run a portable heater. You may notice that the calculation for 4.2 kWh at a cost of $0.12 per kWh didn't equal $0.504 (after all, 4.2 x 0.12 = 0.504) but that's because an electric heating system isn't "on" during it's entire run time. Typically, the control (usually a thermostat) for an electric floor heating system will cycle on and off to get the temperature in the correct range. This means that you'll be charged less for electrical use than if the system was "on" the entire time (see "Duty Cycling for Electric Floor Heating" section below for more information).
How much energy does a master bathroom use?
Assuming the average master bathroom is about 160 square feet in size, a floor heating system running 8 hours a day would use 19.2 kWh per day or 585.6 kWh per month. Although the energy consumption for such a large room is higher than a single air conditioner or portable heater in this case, you would still spend less in operating costs.
How does a floor heating system work?
The way that a floor heating system is able to achieve different floor or ambient temperatures is by using a specifically designed floor heating thermostat, like the nSpiration Series from WarmlyYours, that employs a functionality called a duty cycle. This essentially means that the thermostat will turn the system on until it reaches the desired temperature and then it will turn the system off. The system will then kick back on once the temperature drops below the desired level. The duty cycle functionality ensures that your floor heating system doesn’t use unnecessary energy while simultaneously increasing your comfort by allowing you a high degree of control over your system.
