Combi boiler pressure

[Miss Chief]

Please help no time to call an engineer in. My boiler works fine although it does from time to time lose pressure but I just turn the lever and top it up. However i have recently started using it on timer and just came home to hear it trying desperately to start but due to the drop it pressure it could not. What happens if I am not here ? will it just turn itself off or blow up ? am very worried - please help !!!!

Trying to operate the boiler with too low pressure will not harm it it will just lock out. Do not be tempted to over pressurize either 1.5 bar is about right. The reason for the pressure drop can be
one of many and often technical so rather than call a heating engineer out make an advance appointment and save some dosh. Avoiding a frozen/leaking flat or house is one good reason to find the time - I have seen the results.

Its a Britony Combi boiler

Thanks for all your replies - I really wish I could call out an engineer but just can't get the time off work and going away and hence my worries as do not want it to cause problems whilst I am away.

it gets a bit complex now if your boiler has a low water pressure switch> no problems if it runs out of water if how ever like a lot of combis it just has a pump pressure switch it can ruin the pump if it runs low

If I just leave it off for a week in this cold weather I am likely to flood ?

yes your likely to have a freeze up and burst,you had better get some one in to sort it prevention better than cure

if you do go down this route you will need to drain all the water out of your system before you go

If you losing that much water, it must be going somewhere... underfloor? In the walls? Outside? Best find out rather than just keep topping up..
