Boiler Pressure and Central Heating System Pressure -- Why

The central heating system is sealed (closed) and pressurised, usually to between 1 and 1.5 bar (cold). This pressure is the boiler pressure. When the system heats up, the boiler pressure will usually rise … The central heating system is sealed (closed) and pressurised, usually to between 1 and 1.5 bar (cold). This pressure is the boiler pressure. When the system heats up, the boiler pressure will usually rise a little, normally by up to half a bar. The position of the circulating pump in the system can slightly alter the pressure at the gauge too.

Types of Central Heating Systems - Boiler Guide

The pressure at the tap of a high pressure heating system is the same as the pressure of the mains which in most cases is a lot higher than you would normally experience. These particular central … The pressure at the tap of a high pressure heating system is the same as the pressure of the mains which in most cases is a lot higher than you would normally experience. These particular central heating systems are great if you have a high mains pressure to start with but if the mains pressure is low then the system is unsuitable.
