@cathoderay I did some maths over my lunchbreak and I think I've got an explanation for why there is a polynomial in the relationship. I think it is...
I also found other forms of the curve that better fit the data when doing my EDA, many of which confused the hell out of me, including the polynomial ...
@cathoderay I've made a few modifications having looked through your posts. First, the problem with applying the "no setback" model to the "yes setb...

It's also 2.4kWh extra heat generated in your home (assuming the circulating pumps are inside the thermal envelope of your home).
