Running an S9 is not economic where I live.
Running an S9 instead of an electric heater/gas on the other hand sounds very reasonable. Also given I produce some electricity myself.

Yeah definitely better than running an element based electric heater. At least an S9 produces more than just heat 😉
It doesn't make much sense in my climate (and electricity prices) but it's still interesting to me.
It's amazing the difference a better fan makes to the noise.
