Hi, I have install a wpb buffer tank & solar panels. The buffer supplys the ufh and the dhw. At the moment the wpb comes on at 55c and cuts out at 60c. This seems high to me as the solar panels can not keep the boiler off even in summer. If I turn the temperatures down will it effect the ufh? Was thinking of turning it down to switch on at 45c and switch off at 55c. Any body any experience of this?
