Believe it or not you can use a mailbox to create a wood stove. While I’m not sure how big of an area it can heat, it’s certainly a low cost alternative to buying a traditional wood stove.
There’s nothing like creating your own heat to warm your home. It’s virtually free (with the exception of the time it takes to gather and prepare your wood).
Traditional homes can be heated by wood but take much more resources to heat. Wood stoves are ideal for tiny and small homes because they can be heated quickly and don’t take an excessive amount of wood to do so.
