Any heating engineers on here?
Moved to a bungalow about 3 months ago and having hot/cold problems with the hot water and shower. Radiators work perfectly with no cold areas they have been bled. Viessmann 30 kW combi boiler approximately 12 metres away from taps/shower situated in the loft. Would a faulty diverter valve cause these issues? Or if the valve was faulty would it effect the radiators as well? If the heat exchanger was air locked or blocked would this effect both hot water and radiators. Thanks in advance for any replies.
