How does a central heating system functions?
A central heating system contains a primary heating component such as a boiler or furnace usually installed in a hidden area such as a basement or garage. Its principal function is to distribute heat throughout your entire room by typically pumping warmed air via a system of air ducts or by sending steam or hot water through pipes to either convectors or room radiators. It is imperative to note that both gravity and forced-air heating systems are equipped with at least one thermostat which turns the cooling/heating unit on and off, regulating the temperature of the room appropriately.
Homes that do not have the central heating usually use electric baseboard heaters, in-floor or in-wall gas heaters. Ducted air systems are perhaps the most common types of cooling and heating in many homes.
