What's your point Gas2Air? When the siezed pump was replaced last April the 3-way valve head was replaced also. The engineer didn't do a proper test as the CH trial did not activate at the first couple of attempts and he replied that the new three-way valve head would sort out any switching...

This may have been the original post you saw? positive result, but you will need an electrician. See Fault 2, may be helpful, but check your Grundfos pump? This was the outcome... ...things were really getting bad with the heating so my son came round on Tuesday and went through the electric...

I originally posted this on Dec. 2nd last year: I had a new Grundfos UPS2 15 50/60 pump fitted in April this year by a local heating engineer as the other one seized and blew fuses. Two weeks ago we switched CH on (through wall timer programmer in airing cupboard) which controls water and...

Well Stem, I said I would get back to you, well here it is... very positive result - yippee!! Thanks for your insistence that the electrics should be checked - valuable lesson. Like most families if there is something you want done by a family member (my son) you are usually the last person to...

I am very grateful for that STEM, I will get him to check it out and let you know how we get on and what we find. It may be a couple of days, but whatever, I will let you know. Again, many thanks.

Thanks for that STEM. The CH, once fired up by triggering the HW, will continue as normal and the boiler reacts to demand from the temperature of the heating. Just to clarify again, the CH heating works fine on its own without HW being on, but it needs the HW button pressed to trigger the pump...

I had a new Grundfos UPS2 15 50/60 pump fitted in April this year by a local heating engineer as the other one seized and blew fuses. Two weeks ago we switched CH on (through wall timer programmer in airing cupboard) which controls water and central heating. The Grundfos fails to switch on...
