@jamiejones85mespa your comments are spot on with my thoughts the past few years. As energy prices soared, id decided to invest in Solar and a Heat Pu...
@andrewj I couldn't imagine living in my house at the temperature your seeing, mines set at 20.5C for a comfortable environment downstairs and 19C ups...
@swwils good results supporting running heat pumps at lowest FT that will keep the home warm and not overheat it @andrewj are you able to adjust you...
Has anyone seen a graph of efficiency vs Flow Temp. Trying to achieve FT of 45C when it’s-12C outside sounds like a step to far. with my setup, ive no...
@kevh they certainly have updated the App to allow 45C, you can see the screen grab I di a few days ago shows 50C as the lowest. I’ve changed mine t...

@kevh todays COP is 4.02 (0.5-6.8C), 2 days ago was 4.50 (5.5-8C) The lower overnight temperature has affected the performance, likely more defrost ...
The App says it choses the top temperature when OAT is above 12C, my system is running at 36C today and its 6.8C according to Cosy HP. Logic would sug...
