Central heating system boiler diagram.

This diagram illustrates how simple the heating system connected to a combi boiler is. Built with the same quality and attention to detail as central boiler s outdoor wood furnaces the forge is a better way to heat with coal. Single pipe feed and return micro bore. The vented boiler regular boiler and combination boiler systems probably account for over 95 of water based central heating installations.

The diagrams below show three central heating types. A water central heating system consists of basically the boiler the radiators and the interconnecting piping. Conventional boiler this boiler is the most basic type it just burns fuel to make heat for central heating or hot water. System boiler this boiler provides central heating only or heating and a store of hot water in a hot water cylinder tank.

Building regulations always recommends a system filter be fitted to your heating system pipes prior your boiler to prevent any damage to key components. A system filter is a specifically designed unit which aims to remove and filter magnetic and non magnetic contaminants from your central heating system before they reach your boiler. Boilers convert fuel into usable energy and how much of the fuel ends up being converted is reflected in the efficiency rating. Central heating system diagram with high pressure boiler this type of system operates at mains water pressure and uses a stored hot water system.

System boilers are slowly becoming more common. So if it is lashings of hot water at a forceful pressure you are looking for then this is the system for you. Water central heating the pipework. The boiler heats the water and normally a pump circulates the water through the pipework and radiators and back to the boiler.

The boiler diagram below works by heating the central heating water and pumping it around to the diverter valve. Effectively the higher the efficiency rating the less fuel the boiler. This is then diverted from the central heating circuit to go into the water to the heat exchanger where it passes the heat from the central heating water to the cold water coming into the boiler. System boilers have a central heating output rating which gives an idea of how many radiators the unit will be capable of heating up.
