New smart circulating pump/ are they win or bin

[Dan]

View attachment 29439 Dab Evo pumps also give trouble. Electronics and heat don't mix well I suspect, although it might just be faulty electronic parts.
The pump in the photo is 1962 and has been working virtually everyday from then. I was in same house that still has the original owners this week and the heating was still working.
It doesn't even have any isolating valves, but I guess with that reliability it doesn't need them. It is not A rated though, - probably more like Z rated.

Looks like somebody has used it as an anvil at some point too and taken a chunk out of it and it's still fine lol

Couldn't do that with a smart pump.

Grundfos still do a setup like this called pump plan

Grundfos UPP15/50 Pump Plan | Plumb Center

I did see that but to be honest the pipework is all old and battered and I'll have to change the cylinder any way so thought it best practice to just upgrade the lot to a y plan. Think I will quote a small combi also. (Think that may be the most cost effective)

S plan never do a y unless your changing like for like

Dont see many of those around nowadays

Yeah defiantly not. Out of the thousands of domestic heating systems I've wired over the years I think I've only come across it twice. You have to use the supplied grundfos printed circuit board wiring centre unless you want to start adding relays etc....Just another point of failure that's not needed IMO.

To be honest the whole lot is coming out which is why I said y plan. But I'm open to options. It is only a 2 bed flat which Is why I may do a combi

I agree S-plan over a y-plan any day of the week.
