Water Boiler For Central Heating System

Basic water central heating - radiator pipework

Water Central Heating - the pipework . single pipe - feed and return - micro bore. A water central heating system consists of basically the boiler, the radiators and the interconnecting piping. The boiler heats the water and (normally) a pump circulates the water through the pipework and radiators and back to the boiler.

What Should The Boiler Pressure Be When The

If your central heating system is turned off the boiler pressure should be between 1 and 1.5 bar. This means that the needle should still stay in the green area of the pressure gauge. Depending on the make of your boiler, the recommended optimal working pressure by most manufacturers is 1.3 bar.
