How Radiant Heat Works
Radiant heating involves the transfer of heat from a warm surface to a cooler surface without the need for a medium like air or water. This transfer of heat through electromagnetic waves is called radiation. The warmth radiates from heated objects and surfaces, such as a heated floor, to cooler objects and surfaces in a space.
This results in a comfortable, uniform heat distribution.
Explanation Of Radiant Heat Transfer
Radiant heat transfer occurs through electromagnetic waves that radiate from a warm surface to a cooler surface. The warmer the surface, the more radiant heat it will emit. The radiant heat travels through the air and heats up cooler objects and surfaces, balancing the temperature in the space.
Types Of Radiant Heating Systems: Electric And Hydronic
There are two main types of radiant heating systems: electric and hydronic.
Electric radiant heating systems use electric cables or mats installed beneath the floor or in the ceiling. The electric resistance creates heat, which is radiated to objects and surfaces in the space.
Hydronic radiant heating systems use hot water flowing through pipes to radiate heat to objects and surfaces. The hot water is heated by a boiler or water heater and is distributed through pipes installed under the floor or in the ceiling.
Comparison Of Electric And Hydronic Radiant Heating Systems
Both electric and hydronic radiant heating systems have benefits and drawbacks. Here are some key points to consider:
Electric radiant heating systems:
- Lower installation costs
- Easy installation
- More flexible in retrofit applications
