Do you have the make and model of the boiler?
ok, so a combi boiler.
Hot water does have priority as do all combi's.
Are you saying that the boiler is working correctly (keeping the house warm) but turning on and off every 10 minutes?
Or boiler continuing to run even when off at stat (above 15 degrees)?
