The boiler is a Warmflow B1 Oil CH Boiler.
Does the thermostat fail in an open state or closed state with a hard failure?
Can they simply start to malfunction and not control the temperature correctly in a soft fail situation?
The boiler is working but the homeowner says it's running all the time.
Thanks.
