I have a thorn central heating boiler , when using water only the water is piping hot (reasonably quick) but when using water and heating it takes alot longer to get hot and also is not as hot. Water only does not work on gravity due to it being a fair distance away from the hot water cylinder so we had to have a pump fitted, could this be the reason why?

we had the boiler moved 20 years ago, and the person did not put a motorised valve on it. We only have this problem in the winter because obviously we use the hot water and central heating together
