The case for an expensive heating system built around a powerful boiler begins to collapse as the building enclosure becomes better insulated and air-sealed. Foundations should be well insulated and keep water at bay. Depending on where you’re building, a conventional foundation could be made from poured concrete, brick, block, or stone.
