Boilermate boiler pump replacement

[plumb_know]

Hi Everyone,

Replaced boilermate boiler flow/return pump yesterday as old one was fried but just used a standard grundfos ups3 as seen people say standard pumps are ok to use for boiler & heating circuit of boilermate, customer says heating demand is constantly on now. I just wanted to check this would not have anything to do with the new pump as in the past i have always just fitted the manufacture replacement for the existing pumps, but do not see why this would affect the heating calling for heat anyway??

I personally think it would be a controller issue or boilermate PCB but just wanted some some more experienced heads opinion before i go back out. I put new pump valves on so wont be massive issue if i need to get the original pump and fit, but dont want to do this then it be a separate issue.

Appreciate your advice.

Many thanks

Which BoilerMate is it as there are a few different models? In my experience of these when a pump burns out it takes the pcb out with it, not always but because the pump is trying harder it increases the load through the pcb and melts the chip.

If the original pump was a GT089 for the A series. I would replace like for like.
