Hi
My rads only heat when the hot water is on. On cold days when the hot water and rads have been on for an extended period the rads go cold. Running away some of the hot water restarts the sytem. Am I right in thinking this happens because the hot water reaches the thermostat temperature? My first thoughts were that the problem was with the motorised valves. I've had a look at them in the airing cupboard and there are two two port valves. A Honeywell one for the water and a myson one for the rads. When the rads are turned on either alone or in combination with the hot water the myson valve opens. It seems that this is not the problem. What I have noticed though is that the pump doesn't come on when just the rads are turned on. Has anybody got any ideas?
