@skylar @Edent old school immersion heaters and storage heaters still exist, and I think in cases like this could make a lot of sense. My flat has both, and the moment I’m done buying it from the landlord they’re going on smart switches hooked up to Octopus Agile pricing.

@skylar @Edent there’s also just plain old electric radiators. Not sure what the power usage looks like there and how viable it would be to run them off a home battery.
