Small update on the findings from the data

image

My calcs say that the days at 1 and 2 degrees were about 25% and 20% more efficient without the LLH. However I would note these results are estimates for with the LLH as it never got that cold for the time it was installed. However the data looks fairly solid.

12kW Midea ASHP - 8.4kw solar - 29kWh batteries
262m2 house in Hampshire
Current weather compensation: 47@-2 and 31@17
