The sun

It’s free, and the most en­vi­ron­men­tally-friendly home heat­ing op­tion avail­able.

You’ll need large north­fac­ing win­dows to al­low the sun to shine in dur­ing the day, a large ther­mal mass such as a con­crete floor to store the heat, and in­su­la­tion so the heat isn’t lost too quickly at night.

And you’ll prob­a­bly still need other heat sources for the cold­est days.

If you’re de­sign­ing a new home, in­cor­po­rat­ing some pas­sive so­lar heat­ing into the de­sign may not cost very much at all. It may also be pos­si­ble to in­clude some so­lar fea­tures when you’re ren­o­vat­ing, but it’s harder.
