Biasi 24s Combi Boiler Losing Pressure

Hello All,

I have a Biasi 24s Combi boiler since, purchasing the new home around one year ago. From last few days, I am noticing that the pressure meter certainly not stayed where it was actually set. Apart from this, the boiler is losing the pressure on daily basis. I cannot see any visible leaks in the boiler. It is quite tough to re-pressurize the boiler. What should I do? Should I replace my boiler?



Hi Adam, if your Biasi Combi boiler is losing pressure then, it can be a sign of an issue with boiler’s central heating system. Firstly, do check the boiler’s pressure on the pressure meter & make sure that it should be over 1. Secondly, check the different valves on the radiators in order to ensure that radiators are not dripping or leaking. In case they are, do tighten up as needed. On the other hand, if you have bleed the radiators recently then, it could be a reason for low boiler pressure. You can fix it easily by simply topping up the levels of water in a filling loop. In case, it does not works do contact a qualified boiler engineer because it could mean that boiler’s pressure relief controller needs replacing.
