▲ 852 ▼ Price of electricity in Finland peaks at 2.35€/kWh today. Keeping my tiny granny cottage warm costs me over 50 euros for a single day. It's negative 25C (-13F) outside.

[–] Linssiili@sopuli.xyz 22 points 2 years ago* (1 child) Well, here (in middle of finland) the sun set at 14:30, so there wasn't all that much solar energy available. Also heat pumps are always at least as efficient as straight electric heating. permalink fedilink source parent hideshow 2 child comments replies: [–] nilloc@discuss.tchncs.de 1 point 2 years ago It think above -20C or so, cold weather heat pumps are still way more efficient than resistive electric heating. Good R-factor insulation is probably the most important upgrade in OP’s case. There are people where I live in the Northeast who heat their homes almost exclusively with the waste heat from cooking, electronics or old incandescent lighting. They have like R-30+ homes and really neat ventilation designs for cooling in the summer too. I had plans to build a tiny home with Vacuum insulated panels and a small marine stove for heat, until we had a child and plans changed. Now I’m looking at a solar battery setup with geothermal heat pump that will probably cost nearly what the whole tiny home was gonna be. permalink fedilink source parent
