Our central heating system has a Tower MV2-22C motorized valve im not sure if its shot or needing a bit of work done on it.
when you put the hot water only on two of the rads upstairs get lukewarm, but when you put both central heating and hot water on everything works fine, when you switch the room stat up and down you can hear the valve opening and closing, so why would the rads be warming up slightly when hot water only is selected?
