So something like this. We have ours set on a low setting which is 600 Watts. We leave it running around the clock through winter in the middle of the common area. We dont heat bedrooms (close all the doors aside from maybe bathroom) and just use heated blankets which we find quite comfortable. We spend 9 cents per KWH so that heater running 100% duty cycle will cost us about 40$/mo. The house remains at 55-65 Degrees F (15-18C) through most of the winter, which is fine when you have a sweater/hoodie on and some thermals on the legs and wooly socks. At night it will regularly drop to -20 to -35C here but its not -35C continuously. We've had zero issues with plumbing in the house. Im not aware of anyone thats had fire hazards with a radiator space heater. We cant afford huge heating bills either, but you find ways to deal with cold climate even if thats just layering up some. Its nice to have teeshirt weather indoors through winter and have every room in the house at perfect ambient temp and no cold floors for bare feet but its also wildly wasteful with energy.
According to google, Germans pay an average of 32c per KWH which is definitely higher than we pay here in the US, but even at the rate of 3.5x the cost that gets you to 142$/mo for electric heating a home or 130 Euros.
Making electricity greener is much easier than trying to find cleaner burning fuels and obviously the national security issues associated with foreign oil/lpg/lng. People should take it upon themselves to migrate towards cleaner solutions instead of waiting for gov to force it on them. I appreciate the downvotes, but this is the reality of life moving forward. There is no carbon based fuel for heating homes thats 100% clean but there are lots of options out there that are carbon neutral. As climate change moves forward we're all going to have to get a lot more willing to bend a little on our convivences and comforts. Im from Arizona and if I managed to adapt to cold climate on a budget I promise people in Germany can too.
