We have recently moved into a new house and have a problem with the domestic hot water. We have a vaillant combi boiler (do not know the exact model), central heating is fine and domestic hot water downstairs seems to be fine. The bath and shower upstairs sometimes fails to light the bioler. The bioler clicks and click as you can hear it trying to light but it does not fire. We have to turn the hot water tap or shower off and try again, after a couple of attempts it will eventually fire and give hot water. The shower is more of a problem than the bath, but I am presuming this is because the water pressure through the shower head will be less. Also, if you can finally get the hot water running and get into the shower, sometimes it will go cold on you again (not very nice at 6 in the morning).
We have a BG contract and they can out a couple of weeks ago to replace a leaking pressure valve and we mentioned this to him and his said in some houses and certain boilers it is normal as the water pressure is not high enough. If this is the case, is there anything that we can do?
Many thanks in advance.
