Odyssey Posted November 1, 2021 Share Posted November 1, 2021 Calling all heating engineers! My central heating pump keeps running and doesn’t switch off. Even after the heating and hot water time clocks have shut the boiler off for the night. Any suggestions on what may cause this? Is there an easy fix or do I get heating engineer in to sort it out? @jonnyswamp is this something you can help with? 😬 Quote Link to comment Share on other sites More sharing options...

Saintly Fish Posted November 2, 2021 Share Posted November 2, 2021 @Odysseydo you have a combi boiler or a "traditional" system? Modern boiler have a pump over run stat on the pcb which could be playing up or, if you have an "S" plan system (2 control valves, one for heat one for HW) one of them may have the switch live switch stuck open. Pumps don't have permanent lives, they are all switch controlled. Quote Link to comment Share on other sites More sharing options...

Pumps don't have permanent lives, they are all switch controlled. Traditional system, boiler with hot water tank. Pump is in cupboard with tank. Sounds like I need a pro to check PCB then and replace by sounds of it 😞 Quote Link to comment Share on other sites More sharing options...

Odyssey Posted November 2, 2021 Author Share Posted November 2, 2021 So I’ve reset the timer clock and the boiler and so far it’s working…. Gremlins somewhere in the system…. Hopefully they keep away! GPSguru 1 Quote Link to comment Share on other sites More sharing options...

Saintly Fish Posted November 2, 2021 Share Posted November 2, 2021 @Odyssey as a side thought, do you have or have you seen an anti frost stat anywhere? This could also throw a live to the boiler once temps outside drop below 5deg C. Quote Link to comment Share on other sites More sharing options...

I need to climb over an old floor and clear out my timber store but that’s on my to-do list after work as I was wondering if there was something like that as there was a ground frost here last night and it’s still cold now Thanks for the tips chaps, much appreciated! @JonC see, thee guys can be nice 🙂 Saintly Fish 1 Quote Link to comment Share on other sites More sharing options...

Odyssey Posted December 2, 2021 Author Share Posted December 2, 2021 Yep….. Boiler is in a boiler house that I used as store for spare DIY materials, the frodt sensor had been knocked so anything less than 10deg meant it kept the pump running… Quote Link to comment Share on other sites More sharing options...
