Hi, I have a combination LPG converted boiler and the hot water pressure throughout the whole house is exceptionally poor, it gets even worse when you have more then one tap running at a time. The pressure even drops if you are using a hot tap and then turn on a cold tap elsewhere in the house.
the boiler wasa purpose bulit fit for conversion and was fitted and converted by a CORGI guy. I dont know if pressure was poor before because we had the old cylinder style system.
I am getting really tired of showering in a drip, any suggestions would be welcome. The cold water supply to the house comes through a water softener first, if that makes any difference., although I have bypassed that and it makes no differnce.
thanks in advance
If your cold water pressure is poor - then your hot's going to be too.
Check mains stop tap is fully open, water company's have a legal obligation of providing 0.7bar pressure to your house - check this, if it's lower get the waterboard to check/upgrade pipes.
If it is just the hot water you have problems with - there'll probably be a filter on the cold water inlet to the boiler, cleaning or replacing this should improve performance.
As for using more than one tap at a time - that's a problem with combi boilers, you'll never overcome this whatever the flow rate is - using more than one tap the flow rate will alter.
