Short answer: most people put it 50 to 200 feet from the building they're heating. Check with your insurance company first, since many have a minimum distance.
Things to think about
- Cost: underground line and trenching are priced by the foot, so closer costs less.
- Space: leave room for the boiler, your woodpile and an ash can.
- Insurance: many companies have distance rules. See insurance requirements.
- The mess: wherever the boiler goes, the wood splitting mess goes too.
- Other buildings: planning to heat a shop or pool later? Pick a spot that's handy to those too.
Want it in a shed? We only recommend that with boilers certified for indoor use, like the G Series. Ask us about your setup.
