Similarly, you may ask, why does my boiler keep losing pressure?
The most common reason for a boiler losing pressure is that there is a leak on the system somewhere. This could be a leaking radiator valve, a pipe or anything else that is causing water to leave the system. For example, the Pressure Relief Valve may be failing causing the boiler to lose pressure.
Subsequently, question is, can a boiler lose pressure without a leak? Note, however, that even if the pipework is wet to the touch, this does not necessarily indicate that there is a leak - it may be caused by condensation due to temperature differences. If your boiler continues losing pressure and there is no leak, then there may be a fault with the boiler.
Simply so, how often should a combi boiler lose pressure?
If the pressure has fallen to below 0.5 bar (often indicated by a red section), then it shows that some water has been lost out of the system and it must be replaced. The pressure in a central heating system will usually need to be topped up only once or twice a year.
How often should you need to top up boiler pressure?
Topping up once or twice a year is normal, but it will dilute the corrosion inhibitor, so maybe add some every five years.
