Forced air heating systems
In this type of system, heat is distributed throughout the property using heated air. The heat — whether it’s created through electricity, natural gas, boiler, or a hot-water coil — is carried by air, which is then blown by fans through the duct system and released through vents located in the different areas of the home or building. It is one of the most affordable types of heating systems.
Radiator and convector systems
Radiators and convectors are heating units that act as heat exchangers. A fluid, like water or steam, comes from a central boiler and passes through a series of coils, transferring thermal energy into the room. The coils are usually found in free-standing radiator units or as tubing underneath the floors and walls.
Electric resistance heating systems
Typically composed of electric coils similar to the heating implements of a bread toaster, an electric resistance heating system converts incoming electric energy into heat. The heat rises through vents while the cool air is drawn into the bottom of the heater.
