Heat sources
A heat pump on the well feeds the existing heaters first; the oil boiler covers whatever it can't. Select a row to see its design day.

Through the year
Heat needed each month from the ECCC hourly temperature distribution, and how it splits between the selected heat pump and the oil boiler.
