Motorized valve

[bikeit]

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?

sounds like the motorised valve is passing slightly when closed

Can this be fixed or does the whole lot need replaced?

 

[ianmcd]

probably best replacing it, you could mess about cleaning it and stuff but at this time of year I would just replace it, doesnt need to be the same make of valve so see what you can get a deal on ebay with

Plumber coming tomorrow to look at it he said its a days work to replace it as the system needs drained down below the valve? his phone quote was £200

All sorted now.
The plumber who quoted £200 was told to take a hike.
New valve fitted and some Fernox put into the heating system, the rads get hot a lot quicker and are a lot hotter.
