Which is the pressure tap on a boiler?
Normally the pressure gauge is located on the front of the boiler or under a drop down panel on the front. If not, check on the underside of the boiler as it can sometimes be hidden under there.
What pressure should my Baxi boiler be?
between 1.0 and 2.0 bar
The normal operating water pressure for your boiler and central heating system is between 1.0 and 2.0 bar. If the pressure drops below 1.0 bar, you need to repressurise it. If the pressure goes above 3.0 bar, you will see water coming from the pressure relief valve (usually on an outside wall).
What happens if water pressure is too high on boiler?
If the boiler pressure is too high, there’s an increased chance of leaks developing in the system. But if boiler pressure is too low, the system won’t work as well. So keeping the correct boiler pressure is important to make sure that your system heats your home efficiently.
Why does my Baxi boiler lose pressure?
There could be debris inside the pressure relief valve. This is the safety valve that usually discharges water if the pressure in the system gets too high. If it is dripping with water and the pressure gauge is too low, your Gas Safe registered engineer will need to clean out or replace the safety valve.
Where is the pressure relief valve on a Baxi boiler?
Boilers equipped with brass hydraulics feature the safety pressure relief valve at the right hand side when viewed from the front. On composite types the valve is at the left.
What do I do if my boiler pressure keeps dropping?
How to Fix Low Boiler Pressure
- Switch off your boiler.
- Find your filling loop.
- Check to see whether the filling loop hoses are securely attached.
- Use a screwdriver to open the filling valves.
- Close the filling valves when the pressure gauge reads 1.5 bar.
- Switch the boiler back on.
