Hi,
I've got a two zone radiator system coupled with a hot water tank gas boiler. As its got warmer and I turned the thermostats down to 0, I've noticed the upstairs radiators were still hot.
I thought this might be a thermostat issue, so recently turned the central heating off for summer, leaving only hot water schedules. However, I'm still getting heat loss, pipes at the bottom of my towel rails are very hot, with 0 on thermostat and only hot water on. Seemingly much less hot water in the tank as well currently, running cold after maybe 60% of expected use.
Does this sound like a sensible diagnosis as a diverter valve problem or could it be something else? Are they an expensive fix?
EDIT: i've just read that only combis have diverter valves? Any ideas?
Thanks
