I must be doing something very wrong. I can’t get figures anywhere near as bad as this case study. Maybe my heat pump is faulty? Or maybe it is because I had my system professionally specified and installed?
Mr Coombes ought to join this forum. And or call Heat Geek! I don’t know anything about delonghi heat pumps. But there will always be examples of poor performance. But I was stunned that he has an EPC of Almost A and doubly so if his system is so inefficient. I had my EPC redone this week and I was very disappointed when they rated my DHW poor. They said it was based on the information they hold on Daikin. Would love to hear from others if they’ve had an EPC done post heat pump install and what grading comments they got. I did get good for the Heatpump.
