Tony, Thanks for you continued input. Most of the rads are small under window ones (3 ft long) but double with convectors. If half are 'small' and half are normal (no large ones) it works out about 25kw, say 30kw to be on the safe side.
As for service records, nope!
OK. The house is a large detached Georgian house. The highest rad is 6 meters above the pump and there are 18 rads in 9 rooms and landings.
I dont know the boiler specs, but it is also circa 1979 and is not condensing. It just does the rads, the hot water is off an aga.
Dont know if this is...
Thanks all for your input. As it happens, water can be seen filling the glass viewer in the first pic, something I should have taken note of.
Apparently that means the pump is scrap.
I have been told "A modern equivalent is a Grundfos UPS32-55 with 11/4” unions"
So that is what I will...
Well... I ordered the capacitor yesterday evening and it was here half an hour ago. Fitted and guess what... It wasnt the capacitor.
Oh well, was worth a go.
Re the price, damn!
I will attach pics. Hope you can read them etc. I am adverse to replacing the whole pump as I think it is a £5 capacitor which has gone. I have ordered one and it is a simple job to fit it. I could of course be wrong, but it is worth the £5 to find out.
Thanks for any advise.
I am NOT a qualified plumber....
In reverse:
1. Lag everything!
2. 1 meter extra head will not provide much extra pressure re the work involved
3. I have plumbed a fair bit (DIY that is) and always go for soldered joints in hidden areas and vacuum test. That said, the modern push fit...
I have an Euramo 1030 pump circa 1979. It is blowing the main trip, is not siezed, the windings do not smell burned out and I figure it may be the capacitor that has shorted. It runs for approx 0.5 seconds before tripping. It is rated as light commercial in some reviews, it is a big (12+ room...
