It's not as simple as that. Get a good plumber to look at it; most likely you've an issue with balancing since you've 2 separate heat sources, or the thermostat for the pump being placed to close to the stove so it's cutting in too early before there is a volume of hot water to pump.Every year I have a problem with radiators not working off my relatively new stove. I have done usual checks as per Utube. Pump already replaced last year. I now want to disconnect pump from stove as my gas heating is stress free. Can this be done.
Yes.Could I just change stove and isolate pipes?
All so helpful thanks again.Yes.
But that sounds like the nuclear option. There might be a simple fix to your problem. Or depending on your stove it might be possible to safely disconnect the boiler.
