▲ 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.

[–] qaz@lemmy.world 3 points 2 years ago* (2 children) What about a solar + electric heating? permalink fedilink source parent hideshow 4 child comments replies: [–] 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 [–] DanglingFury@lemmy.world 13 points 2 years ago* (last edited 2 years ago) (1 child) Solar is quite poor in Northern winters. Wind + solar + heat would be a better bet, but the battery required to heat your house for more than a day with low winds would be prohibitively expensive unless you added geothermal to the mix like a geothermal heatpump which is also very expensive. Betweem the gear, battery, geothermal, all installed your probably in the 80k$ range or more. A wood stove would be the best bet permalink fedilink source parent hideshow 2 child comments replies: [–] 018118055@sopuli.xyz 3 points 2 years ago (1 child) Finland has about 5.2GW of wind capacity vs 4.3 nuclear. If it's a windy day the spot price will usually be low. permalink fedilink source parent hideshow 2 child comments replies: [–] DanglingFury@lemmy.world 2 points 2 years ago Good point, for aome reason i was thinking more off-grid than load balancing economics. The battery would probably help lower power by filling when power is cheap and supplying when the rates spike throughout the day permalink fedilink source parent
