How to set the warm end of the weather compensation curve when it's not warm
There was thread somewhere recently, which I can't find now, where someone had a DHW pump that was running continuously. That would be annoying but not a hindrance if the HW is always getting topped up after 10° drops, but if something like that was happening in your system after the end of a heating cycle then you would just end up with a tank of tepid water following a sizeable draw-off. It was easily fixed as the pump wiring had been connected to the wrong socket in the controller. It is worth checking if the pump is running when it should be off – just feeling if it is vibrating should be enough.
