Hi,
The Grundfos Selectric 15 - 50 in our 3 bed semi is still going okay after 17 years but it has taken me a few years to realise it sounds like a Panzer division passing by.
Although I am holding out on the central heating being turned on until Oct, thought I should probably take a punt on a replacement.
Grundfos have just released their latest batch on pumps - the UPS3 15-50/65 and Alpha 15-50/60 seem to be the main options (https://uk.grundfos.com/campaigns/new-team.html).
It looks like the Alpha is marginally more efficient, offset by being about £40 dearer. From my limited understanding, the UPS is the normal like for like replacement (the latest one seems to have some efficiency improvements) but I'm struggling to work out whether the benefits of the Alpha are worth it.
I did ring Grundfos for advice but got nowhere, not helped by these pumps just being released.
Does anyone have any experience or insights on these pumps nd can perhaps point me in the right direction? The next problem will probably be seized valves, so it my be the head only version of the UPS3 in any event!
Many thanks,
Damian
