The saga continues.
I've had new motorised valve fitted. Since then I've had very little heat from the rads.
I've checked power to the valve and have taken the cover off to see what happens. When the HW is on the valve motor operates and the rads get hot. When the CH is on it doesn't move. None of the wiring has been touched although I have checked it.
I've come to the conclusion the valve is either the wrong type or its on upside down.
By this I mean (is this correct). When the HW comes on the valve should operate to direct water to the hot water tank. Normally it is not operated so water goes to the rads.
When I move the lever to manual I get the same effect as when the HW comes on the rads get hot but not as hot as they do when the valve is operated, checking this is becasue the valve doesn't move quit as much.
So should I get the plumber to put it on the other way up, or should I get him to get one that works the other way round to one I've got? In other words in to supply water to the rads when the motor is not working.
I hope that makes sense because it's driving me nuts.
By the way the valve is a Boss BMPV222, according the instructions on the info. sheet he ahs put it on the right way.
