Hi

Our old house use to have a combi boiler but our new house has a Potterton Suprema boiler and storage tank. There is no thermostat on the tank so when the heating is on it also heats the water. Fitted a new controller so can now heat water or water and heating. This seems to use a lot of gas though. Have been told that you can fit a valve to stop heating water and heating at the same time. Is this true and will it cost an arm and a leg? Will I need to run another control cable from the valve to the controller as well?

It seems to me that your system needs upgrading from your description not only to include a tank stat but also a three port motorised valve. Perhaps you have a gravity hot water system. Just fitting a different programmer wont help without that valve.

I'd suggest you call a plumber or two to quote.

Cheers
