Boiler trouble....CHW fine, HW dodgy....

Postby bex1 » Sun Sep 16, 2007 4:44 pm


I have a wonderful (!) Ideal Isar boiler - 1 year old. For some reason we dont get much hot water - eg. runs enough to fill the sink, but not bath and starts to run cold - it used to fill on demand, what can i do?

No error messages are coming up does anyone have any advice for me please??

Thanks in advance for any help you can give - it would be fab if i can get this sorted

Simply Build It

it sounds like flow sensor may not be functioning correctly, on these boilers they are called thermistors and a bit fiddly to get to and if this is the case will required a heating engineer
other simple things to check are the system water pressure and that the water is not running through the taps too quickly for the boiler to heat. but that would probably be too good to be true.
