Question:
We want to install a diesel heater in our sailboat. Would the Air 2D work, or is it just for land vehicles?

Jeanette, the Air 2D Heater # AU56MR is actually marine-ready! It’s commonly used in sailboats, trawlers, and workboats. Just be sure the exhaust exits above the waterline and everything is sealed against water intrusion.
The included fuel pickup hose works great in an auxiliary tank (some people tap into the boat's fuel tank but that's a little more involving. If you need to heat a larger cabin, the Air 4D # AU96MR is the next step up.
What type and size boat are we talking about here?
