What's different about this calculator?

Traditional BTU calculators tend to overestimate the BTU needs of your space. Having a larger than needed heater makes sense with a traditional heating system, but if a wood stove is too large for a space, you won't be able to burn the stove cleanly without overheating your living space. So many people, even in traditional houses, end up with stoves that are simply too large to be useful!

This calculator is specifically designed to size small wood stoves for tiny spaces. If you want to use a wood stove to heat your tiny home, bus, RV, yurt, shed, van, or other tiny structure, our stove selector is the best place to start.
