It's just a regular performa.
The temperature knob for the HW doesn't appear to do anything.
Whereas the one for the CH will fire the boiler on and of.
Thanks for the replies guys, at the end of the day what I may have considered 'normal operation' may not have been just that.
Hope that makes sense.
baxipoti - are you suggesting that in fact the boiler is behaving as it should?
Hi all, first time post here :D
We have a Potterton Performa 28. In recent months it's had a new diverter valve and heat exchanger ( secondary). It's been working well until recently. The heating works ok, until you try and use the hot water.
If the heating is on or off, as soon as open...
