Ive just had my system changed over to a y plan and although iam more than happy with the results iam just unsure of one thing.
If both the HW and CH are switched on the pump runs continuously, if i have the HW running the pump runs continuously but if i only have CH or the cylinder stat stops calling then the pump only works when the boiler ( myson economist) fires up and then stops again when the boiler stat kicks in.
The sparky asked me to give it a good run and see how things go and if there were any problems he would come back but i dont want to waste his time if everything is working as it should.
