Hi,
Our 20+ year old Grundfos UPS 15-50-130 Selectric, not within the boiler, probably needs replacing and would appreciate some choice advice.
1. Seems the UPS2 15-50-130 is a direct fit, but cost about £140 and its said Head Only units are available, but hard to find at a lower price.
If buying a complete UPS2 and taking off its head to replacing the old head a good thing to do ?
2. Also found some places , eg SF and TS, stocking the even newer UPS3 15-50 for around £120 which again are said to be compatible.
Again wonder if their pump head only could be swapped over and if they are a better buy than the UPS2 ?
3. While searching seems there are some Grundfos Clones around, under various unknown names to me, for as little as £40, are these possibly ok or ones to really avoid ?
thanks
