Hot radiators is getting me into Hot Water (or not)

[Dan]

I have a Potterton Netaheat Boiler with a EP2000 programmer and Potterton Thermostat. During these summer months I have discovered that in order to get HOT water, I have to turn the Thermostat right up above the day time temperature. So even if the Central Heating is on twice a day and the Hot Water on twice (which they are programmed to), unless the thermostat is on 30 degrees C or higher to get the green light indicating termperature not yet reached we cant get Hot water......? This means the radiators get HOT, and hence why I never discovered this problem in winter. Please any advice gratefully received

Probably a faulty neoprene valve in the boiler??

it sounds as if the system is not wired and/or plumbed correctly if you google this group for Y-plan and S-plan you should find what sort of system you have and how it should be set up, and then we can help you find out where it's wrong
