I replaced my central heating pump with some cheap thing off Amazon and I suspect it's a pile of rubbish as from installation it's been like a jet taking off in the airing cupboard and now the boiler just keeps locking/overheating and I have to press the button to reset it. I've tried bleeding the pump and the radiators and that seems fine BUT it does sound like there's air in the system still so no sure.
Anyway, the old one was a Grundfos 15-50 130 and I want to replace it again with a Grundfos one. But I'm not sure which one to go for. The one I'm looking at is this:
“New Model” GRUNDFOS UPS3 15-50/65 Pump - Replaces UPS2 15-50/60
This is what came up when I searched for mine. From what I gather, the 130 bit is just the face length and this one says it'll replace all 130mm face length pumps. The rest seems to match.
Could someone confirm, or suggest a pump that might be better, please.
