Potterton Promax HE - Will it cut out if pump fails?

keithmdw · 29 Oct 2008

I have the above boiler and my pump is on its last legs. My plumber has let me down and can't change the pump this week.

If the pump fails while running am I right go thinking my boiler will realise there is no water flow and cut out?

Yes, it SHOULD sit there doing nothing. It has a flow switch. but they do stick on sometimes. You could test it by getting the pump switch "between speeds", which will probably stop it.

Thanks. Don't really want to disturb the pump as it really is on its last legs and I don't want to push it over the edge in the cold weather with no plumber for a week.

What are the consequences of the flow switch sticking and the boiler still firing? Would it simply overheat and cut out or could it knacker something?

some banging and crashing before overheat cuts it off and all should go quiet.

Should be able to handle an overheat ok. I would rather risk it than being cold! However I am not staniding infront of the boiler so can only hypothisise

Thanks for the reply.

I am definately going to risk it. I am not going without heat LOL.

I have turned my stat down though and lowered the time it stays on for. Also not using hot water. All to minimise the pump use.

Hopefully it will keep going until the plumber gets round to me but if it all packs in then we will have to have the emergency plumber out because its too cold to be without heat for more than a day.

BG will do you a fixed price repair for £180ish and they might be quicker than your plumber.
