In Norway electricity is the most popular form of heating for households at 96% (source). Pure 230V AC is a very high-level energy, and we don’t really need that precision for heating.

This is a project to see if easy, not-perfect, locally generated energy can be used to lower the heating bill.

Disclamer: this is mostly for fun. A more economic aproach would be insulation, heat pump, put on a sweater, etc.
