You need to seriously need to rethink your home. First off, consider getting a radiator heater. These heaters have no fan and are filled with oil to passively heat the air. They are pretty efficient and can heat a small space.
Next make sure you have blinds covering all windows. Windows loss a lot of heat even if they are double paned.
In the spring time it may be worth getting some insulation blown in.

My heatpump is about 3x more efficient than electric radiator.
You’re talking to a guy living in Finland. I think it’s safe to say they know how to efficiently stay warm in winter.
