Paging the plumbers: trouble fitting a radiator

Factual Questions
21

[QUOTE=Quartz]
It’s a dead (burned-out) pump and apparently the system is rather full of sludge. The plumber has returned and replaced the pump, but he says it might burn out if I leave it on. So it’s currently off. The radiators upstairs now work, but not the ones downstairs. He’s suggesting that a full power flush might be in order. He’s also point out a legal issue with the siting of the boiler (a Potterton Profile 50e) and a performance issue.

Sounds like he’s suggesting a new boiler, that may be correct, but I think I’d get a second opinion, even if you have to pay for it.

Well, it looks like the new pump’s failed. £150 down the drain.

As for getting a second opinion, that’s a given with any significant purchase.

If your boiler is very old you will see a dramatic savings in operation. I know it’s a big hit, but it will also add to the value of your home.

24

Yes. I’m trying to think of it not as the initial hit but an annualised cost.

Well, the plumber came yesterday. He flushed the system of gunk and put in a new thermostatic control system. And relieved me of a considerable amount of money. And he put the 3-port valve in the wrong way round! It’s off now, of course, awaiting his return to rectify the situation. I even asked him at the time if it wasn’t upside down!

I sincerely hope that that will be the end of your central heating problems.

So do I! But I now have thermostatically controlled central heating for the first time. And after a break of over 2 weeks, I can have a bath in the morning.
