I arranged for a heating engineer to call around yesterday to have an initial look at the work I need undertaking. He didn't turn up and when I rang him he provided a feeble excuse for not coming. So I'm still looking for a good heating engineer that carries out work in the Reading area.
Thanks again for your detailed responses.
There are two separate motorised valves in my system. The towel rads coming on when the hot water is being heated is usually a good thing. However, on the few summer days where we get high temperatures, it would be useful to be able to turn off the...
When the boiler was originally installed the plumber told me to never turn off the one towel radiator as it was the bypass for the boiler.
The boiler is a Potterton Suprima 120L.

Thanks for your detailed reply. Currently the bypass in my heating system is via a towel radiator in a bathroom. Do you think it would be best to keep it this way or move to the auto bypass and setter solution?
After seeing how large the Magna 25-100 is (it's about the size of a small family car), I've decided to go with a UPS2 25-80 and have managed to source one for a very good price. This is similar in size to my existing pump and will be easier to fit in, as space is a bit tight in my airing...
Thanks for all the replies.
I can get a Grundfos Magna 25-100 for no cost. It's a bit of a beast. Do you think that will be overkill or should I make use of it as it's free?
My existing pump is on the way out. It's a Grundfos ALPHA 15-60 130 and about 16 years old. If I use the Grundfos replacement guide it comes out with an ALPHA2 15-60 130 as a suitable replacement. My system is quite large (22 radiators) and I have found, even after balancing, that the...
When I have my hot water on and the central heating is off, there is still a small flow of hot water through the motorised valve for the central heating. There's sufficient flow to slightly warm some of the closest radiators. Does this usually mean a new motorised valve or is there something...
