Insulate to passive house standard and old lightbulbs throw enough heat - https://www.nypassivehouse.org/how-three-light-bulbs-help-keep-my-house-72-degrees/ https://www.nypassivehouse.org/how-three-light-bulbs-help-ke...
- zanny 8y agoLightbulbs aren't magically more efficient at heating. The other 8 months of the year wasting a ton of power on inefficient bulbs just wastes your money when you could have just used more efficient bulbs and a dedicated heater.
- starbeast 8y agoI think you missed the point. If you can keep a house warm in winter with three light-bulbs, then electrical heating is perfectly viable when running off solar. I wasn't recommending light-bulbs as a heating method.
