Help Powermax 155

[neall]

I hope someone can help or point me in the right direction..I have a Powermax 155 central heating system which has seems to me to have several problems...

Firstly..my radiators will not warm up at all.We normally leave it on constant rather than on a timer..ans just switch up the temp control as & when the house gets cold.....

Then...My hot water runs out if we shower/bath kids wash dishes etc fairly quickly..I then need to press the 2 reset switches in the tank to get the boiler to fire up again for hot water....

I called my local Central Heating chap (corgi registered)..Who has changed the pump..bled radiators etc etc..And has basically said he does'nt know why things are'nt working.....so if any body could help
I'd really appreciate it

These boilers seem to crop up a lot on this forum. It might be worth doing a search to see if your problems have been dealt with before.

do you mean you have to press the ranco overheat stats in its like a little button that pops out sounds like you have a faulty cold start stat to me or definately one of the 4 stats is playing up
