Condensing Boliler - Get Your Boiler Repaired by Recommended Gas Safe Registered Engineer

Combination boilers and system boilers both carry pressure gauges and we're often asked about the pressure shown on these gauges. Any sealed central heating system needs an expansion vessel, a pressure gauge and a pressure relief safety valve.

If you heat water it expands. In an open vented central heating system (with a header tank) some of the water moves back up into the header tank. The expansion does not increase the overall volume of water by a huge amount (maybe 3 or 4 litres, depending on the size of the heating system) but it would be more than enough to burst the pipes if it had nowhere to go.

In a sealed system you have to allow for this expansion. This is done by adding an expansion vessel to the system pipework and it's often inside the boiler. The expansion vessel is just a chamber with a rubber diaphragm across the middle. One side of the expansion chamber is connected to the system pipework. The other side has a car tyre type valve so it can be pumped full of air.

In manufacture the air side is pumped full of air, typically to about 1 bar (about 15 psi). This forces the diaphragm right across to the opposite wall of the chamber. When the central heating system is filled with water and pressurised (to about 1 bar) the water pushes the diaphragm back to about the middle

Get to know "Gledhills BoilerMate"

BoilerMates are thermal stores, in other words a tank full of water heated by an ordinary central heating boiler. The water never changes. It is used purely to store heat energy from the boiler. The stored hot water is pumped around the radiators top heat the house, and is used to heat domestic tap water before it arrives at the hot taps. This allows hot water to taps and showers at full mains pressure for high performance showering and faster bath filling.

The boilermate is very similar to the SysteMate and the two are easily confused. The difference is that the Boilermate pumps the thermal store water around the radiators directly, meaning radiators cannot be installed at a higher level than the BoilerMate cistern. The SysteMate separates the central heating water from the thermal store water using a copper heating coil inside to transfer heat from the boiler primary into the thermal store water, allowing use of a sealed heating system and location of the SysteMate becomes free
