Heating Return Pipe hot and Radiator hot whenever Boiler pump runs
Hi
One or more of my radiators is coming on whenever the Boiler Pump runs ie when the store is being heated. The Heating pump definitely isn't going I've checked, even tried disconnecting it temporarily.
I'm suspecting the NRV Check valve on the Heating pump as it should stop this happening yes?
Any help appreciated.
Pete

Hi Pete,
It could be the NRV or it could also be the bypass valve letting-by.
Hope this helps
