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 boiler diagram.
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.
Building regulations always recommends a system filter be fitted to your heating system pipes prior your boiler to prevent any damage to key components.
Effectively the higher the efficiency rating the less fuel the boiler.
The vented boiler regular boiler and combination boiler systems probably account for over 95 of water based central heating installations.
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.
So if it is lashings of hot water at a forceful pressure you are looking for then this is the system for you.
The diagrams below show three central heating types.
System boilers have a central heating output rating which gives an idea of how many radiators the unit will be capable of heating up.
This diagram illustrates how simple the heating system connected to a combi boiler is.
Central heating system diagram with high pressure boiler this type of system operates at mains water pressure and uses a stored hot water system.
Conventional boiler this boiler is the most basic type it just burns fuel to make heat for central heating or hot water.
Water central heating the pipework.
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.
System boiler this boiler provides central heating only or heating and a store of hot water in a hot water cylinder tank.
You should read this page in conjunction with the page on boilers and the page on heating controls.
A water central heating system consists of basically the boiler the radiators and the interconnecting piping.
Common materials and components.
The boiler heats the water and normally a pump circulates the water through the pipework and radiators and back to the boiler.
System boilers are slowly becoming more common.
The boiler diagram below works by heating the central heating water and pumping it around to the diverter valve.
