AnswersDriveRadiant heating systems supply heat directly to the floor or to panels in the wall or ceiling of a house. The systems depend largely on radiant heat transfer -- the delivery of heat directly from the hot surface to the people and objects in the room via infrared radiation. Radiant heating has a number of advantages.
Is radiant heating expensive?
For new construction, a hydronic radiant floor system is likely to cost more than forced hot air (ducts and registers) or hydronic systems (baseboard radiators). Electric radiant floor heating costs about $6 per sq. ft. for materials but is often less expensive to install because of lower labor costs.

Is radiant ceiling heat efficient?
Radiant heating systems supply heat directly to the floor or to panels in the wall or ceiling of a house. Radiant heating has a number of advantages. It is more efficient than baseboard heating and usually more efficient than forced-air heating because it eliminates duct losses.

What type of flooring is best for radiant heat?
Here are the top 4 flooring options for use over radiant heat.
- Tile Flooring. Porcelain and ceramic tile are great conductors of heat, so your home will get the full benefit of the radiant heating system.
- Laminate Flooring.
- Engineered Wood Flooring.
- Natural Stone Flooring.

Is radiant heat energy efficient?
According to the U.S. Department of Energy's Energy Savers website, radiant heating has a number of advantages over other forms of heat distribution: “It is more efficient than baseboard heating and usually more efficient than forced-air heating because no energy is lost through ducts.”
5
Do radiant heaters use a lot of electricity?
Power Consumption. Infrared heat is safer than conventional, resistive heat, but it takes just as much electricity to produce it. In California, where residential electricity costs about 17 cents per kilowatt hour, it costs about a quarter to run a 1500-watt heater for an hour.
6
How much does it cost to install radiant heat?
There are two types of radiant heating used in residential settings: electric radiant and hydronic (hot water). Electrically heated systems cost more than hydronic systems, about $8.00 per square foot minimum. Hydronic systems cost about $6.00 per square foot minimum.
7
Can radiant floor heating be used for cooling?
Radiant cooling systems have been embedded in the ceilings of adobe homes, taking advantage of the thermal mass to provide a steady cooling effect. Homes built on concrete slabs are prime candidates for radiant heating systems, and radiant floor cooling takes advantage of the same principle using chilled water.
8
What is it that cook with radiant heat?
Cooking with radiant heat is a more physical process. From the burners to the food it requires heat transfer between every component. Radiant cooktops heat by passing electricity through heating elements below the smooth ceramic top. These elements radiate their heat without appreciably warming the surrounding air.

What is ceiling cable heat?
It is, like all electric resistance heat baseboards, fan-forced wall heaters, electric furnaces 100 percent efficient in converting electricity into heat. Unfortunately, many radiant ceiling heating systems were installed when electricity was considerably less expensive than it is now.
10
How does a radiant heating system work?
In a radiant floor heating system, warm water flows through flexible plastic tubing called PEX that is located underneath or within the floors. (PEX is an acronym for crosslinked polyethylene.) The heat source in a hydronic radiant floor heating system is typically a boiler or a hot-water heater.
11
What do you mean by radiant heat?
Radiant heating is a technology for heating indoor and outdoor areas. Heating by radiant energy is observed every day, the warmth of the sunshine being the most commonly observed example. Radiant heating as a technology is more narrowly defined.
12
How does electric radiant floor heating work?
Electric radiant floor heating (RFH) uses heat-conducting plastic mats containing coils warmed by electricity. They aren't heated elements like you'd find in a space heater or on an electric stove. They're actually resistance wires, typically copper or nichrome, wrapped in a water-resistant polymer.
13
What is radiant heat from the sun?
Radiant energy is the energy of electromagnetic waves. It is a form of energy that can travel through space. For example, we receive the heat from the sun, which is located very far from the earth via radiation. The sun's heat is not transmitted through any solid medium, but through a vacuum.
14
What is radiant solar energy?
Radiant energy is the energy of electromagnetic waves. The term is most commonly used in the fields of radiometry, solar energy, heating and lighting, but is also used less frequently in other fields (such as telecommunications).
15
What is radiant heat transfer?
Heat can be transferred from one place to another by three methods: conduction in solids, convection of fluids (liquids or gases), and radiation through anything that will allow radiation to pass. The method used to transfer heat is usually the one that is the most efficient.
16
How does a heat radiator work?
Steam Radiators. Steam radiators work by boiling water to create steam. That steam then travels up a set of pipes into the radiator, which in turn, heats up the room via radiation and convection. As the steam travels through the unit, it slowly cools down and turns into condensation.
17
What is radiant cooling system?
A radiant cooling system is a temperature-controlled surface that cools indoor temperatures by removing sensible heat and where more than half of heat transfer occurs through thermal radiation. Radiant cooling cools a floor or ceiling by absorbing the heat radiated from the rest of the room.
18
What is hydronic heating system?
Hydronic heating is beautiful in its simplicity. The hydronic system simply heats water and moves it through sealed pipes to radiators throughout the home. Hydronic Heating heats water at its source via super energy efficient Gas Boilers. Once used the water is returned to be reheated via a reticulating system.
19
What is convection of heat?
Heat Convection. Convection is heat transfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source of heat, carrying energy with it. Hot water is likewise less dense than cold water and rises, causing convection currents which transport energy.
20
What is a baseboard heating?
Baseboard heating really refers to two separate kinds of heating systems. Electric baseboard heaters are individual units that heat a house room-by-room. They require no central heating and no expensive duct work. Hydronic heating is ideally used with radiant heat systems, where the heating pipes run under your floor.
