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.
I'm sure somewhere in the lockup we have a brand new one (smc)
And these days pumps are designed to fail, if they didn't manufacturers wouldn't have much of a call for new pumps

Sorry didn't know if you knew what they were cant see the branding , don't suppose you took any note of them ?
No offence taken. I knew how they worked but that is the first One I have seen if I am honest. It is an SMC which is what made me post the picture.
As above though the pump is the only thing on the system that is still working properly.
At a guess I would say 60's but the system does look like it has had some work done on it since then.
Dont see many of those around nowadays
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 lolView 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.

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)

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.Dont see many of those around nowadays
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 combiS plan never do a y unless your changing like for like
S plan never do a y unless your changing like for like
