How does a radiant electric system heat a house?
Radiant 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 is the effect you feel from the warmth of a hot stovetop ...
How does a radiant heating system work?
Radiant heaters work by heating the objects in a room and not the air. Therefore a low amount of energy is consumed during air exchange. Conventional heating needs to heat all the air in the room to restore the temperature. During the heating process, some air is moved around by the fan in convection heaters.

Does radiant heat use electricity or gas?
Radiant heating systems require either natural gas or electricity as a fuel source. In the case of electricity, the components are heated by electrical resistance. For natural gas, however, the system does require a boiler installation to heat the water that will flow through the pipes of the radiant heating system.
Does radiant heat need electricity?
There are two main types of radiant heating systems – hydronic and electric. Hydronic radiant heating makes use of hot water tubes that run below the home's floors. Electric radiant heating uses electric wires.
What is the energy source for radiant heat?

How Do Radiant Heaters Work?
These heaters work by generating infrared radiation. The objects kept nearby radiate heat energy at a capacity equal to the temperature of their own. The radiant heaters produce infrared energy, which moves in the electromagnetic waves invisible and absorbed by the objects that fall between the path.
Do radiant heaters heat the air?
In the case of Radiant Heaters, things are different. It generates heat inside and then radiates it to the nearby person or object. This heating process makes the room warm faster than the working principle used in other Heaters.
How does radiant heat travel?
The sun is the greatest source of radiant heat that we know and this heat travels through space in the form of electromagnetic waves, reaching the earth and warming it during the daylight hours. If you stand in front of a fire then radiant heat is transmitted to you, but if someone comes between you and the fire then the heat supply is blocked and you cease to feel the benefit of the heat from the fire. The radiant heat waves travel in straight lines unless deflected by some reflecting surface.
How does radiant heat help in the winter?
Radiant heat can play a significant role in achieving thermal comfort, promoting a healthier environment and lowering building heating costs in the winter. To understand how radiant heat makes these benefits possible we must first clarify the difference between ambient air temperature and the mean radiant temperature.
How to determine radiant heat intensity from a flame?
To determine the radiant heat intensity from a flame on the surface of a receptor, the view factor and the distance between the flame and receptor must be known. The view factor, Fview, is determined by the geometric condition of flame (width, altitude, aspect angle relative to the receiving surface) versus receptor and the distance and orientation of the receptor. The distance and the moisture content in the air also determine the radiation transmissivity, τ. The radiation flux on a receptor given a situation, q ″, is therefore:
What is the energy that is absorbed by combustion gas?
Radiant heat absorbed in combustion gas around the flame is converted to thermal energy , which should be emitted as infra-red ray from the gas to the rotating solids and inner wall surface.
What is the difference between ambient and radiant temperature?
The ambient air temperature is a measure of the average air temperature in the environment, while the mean radiant temperature is a measure of the net radiant heat gain and loss in the environment.
What is the reflector of an electric fire?
If you examine an electric fire, the reflector behind the element is made from a highly polished piece of metal so that very little heat is absorbed but a lot of heat is reflected and concentrated where it is required.
How is steam raised?
In countries where the sunshine is abundant, steam may be raised by reflecting the sun's rays on to a boiler by means of a large mirror.
What is radiant heating?

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.
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 the best floor covering for radiant heat?
Best Floor Coverings for Radiant Heat. In general, floor coverings for radiant floor heat should have high thermal absorptivity and transmissivity. Ceramic and stone tiles are probably the best choice, followed by polished concrete or cementitious composite, such as terrazzo.
