Nice Sunny Day and the radiators are coming on.
They seem to come on first thing and in the evening, which I would say coincides with the hot water sytem coming on.
Could this be the three port valve sticking allowing the hot water from the boiler to pass through the tank and the radiators.
How should I test this?
Thanks
