Hi, I am looking for some help/guidance/recommendations on great plumbers. We have recently completed an extension and had an existing boiler relocated to the new building but we have a problem which the plumber who did the work does not know how to fix and so we are a bit stuck.
When the hot water is on the heating is also on, which will be a massive problem in the summer, and is also making our bills sky high. He did offer us advice to change the thermostat and change the pump which we have done but this has not corrected the issue…
.
Does anyone know why this would be or can anyone recommend someone to come and take a look.
Thank you in advance.
