Central Heat Systems vs Gas Heat Systems
Central heating gets its energy source from a variety of different places including solid fuels (such as wood), water/steam, petroleum and other liquids, electricity, heat pumps, and natural gases. The most common forms of central heating are electricity and gas because they are the easiest to maintain. A gas heater simply takes natural gases and burns them to make heat. This means that they get much hotter than other systems.
Forced Air System
The most common type of gas heating system is the forced air system. This system uses a natural gas burner to heat the air. The particular system works by bringing cool air into the system which is then moved to a heat exchanger that heats the air. The air is then pushed out by a blower or fan through the home’s duct system. A fear I have had about gas heating is the emission of CO into my home. However, my wall has wall vents installed pushing the air outdoors so I do not breath in the fumes. This eliminates the need for a chimney or chimney liner.
Water-Based System
Water based systems use a gas boiler to heat homes. The boiler is the most important part of this particular system. It is almost like a large fire that continually has a natural gas supply streaming from it. This system uses the boiler to create hot water or steam which is then circulated through pipes. Many boilers used in these systems are also used as hot water heaters. These systems can use different ways to create the heat including radiators, floor systems, or baseboard units. Radiators can only be completely on or off because it either has hot water flowing through it or not.
