My system has been running 24/7 on weather compensation from last September until today when I fitted a thermostat.

I did think about just changing the weather comp curve to 20@20, but then the pump would still run.

My wife still has the heating on as of this evening, she wanted it at 24 in the lounge. I tweaked the low temperature end of the curve up from 35 to 37.5 to make the rads feel warm when she turns the stat up.

Off grid on the isle of purbeck
2.4kW solar, 15kWh Seplos Mason, Outback power systems 3kW inverter/charger, solid fuel heating with air/air for shoulder months, 10 acres of heathland/woods.

My wife’s house: 1946 3 bed end of terrace in Somerset, ASHP with rads + UFH, triple glazed, retrofit IWI in troublesome rooms, small rear extension.
