hi there, we've recently been having a few problems with our central heating, pump not cutting out, then boiler not firing up when it should. There seem to be 2 actuators on our system, one for hot water and one for central heating. I've worked out that it is the hot water actuator that was causing the probs. I have forced the actuator into the manual position, my question is, is it ok to leave it in this position long term? Also since doing this it has helped but every now and then the boiler still doesn't fire up and I have to manually reset it - it's a Potterton Suprima 120L, any ideas?
thanks :(
