In a typical hot water boiler system, the fuel is introduced into a pressurized tank where combustion process takes place. A temperature controlling device called thermostat is included in the system which keeps a check on the fuel temperature. Within the pressurized tank, the water combined with a regulated quantity of air is supplied which initiates the fuel burning process. The products of combustion are then passed via pipe towards the cylinder which contains the water. Due to the heat supplied by the hot gases, the water inside the system gets heated. The resulting hot water is then finally distributed by means of an electric pump. The heated water is sent via another pipe to all the parts in the building requiring heat.
In hot water heating systems, the whole system is usually divided into different heating zones in a building. This zoning method offers following benefits:
- It results in efficient heating.
- It makes the living extremely comfortable.
- It makes the boiler operation very simple.
- It offers extremely cost-effective heating solution.
Radiant heating is one of the oldest techniques for generating hot water heating. It is usually applied owing to its highly efficient heating effect. With the advent of new technologies, radiant piping systems have been made extra robust as well as inexpensive. Plastic tubing (which is a more economical choice than other piping materials) has made it conveniently possible for homeowners to have their floors, walls, driveways and pools heated hydronically. Distribution of heated water inside a hydronic boiler system can take place via following techniques:
- Radiators
- Baseboards
- Convectors and
- Vents, also referred to as hydro-air systems
