I have been told that this problem could be due to a faulty Diverter Valve.
Could this be the problem?
What is the purpose of the diaphram unit?
Many Thanks
Hello all.
I've just moved into a house which has a Vokera Excell 80E combi Boiler and Im having problems getting the DHW to work.
When the central heating is on, all that I get from the hot taps throughout the house is luke warm water. It never gets hotter, yet the rads seem to work fine...
