Improved OTG Wood Fire Coil Kit – Pre-Sale Reopening!
Back by demand. We’re reopening pre-sales for the popular, fastest sold-out coil kit model — the Improved OTG.
This limited batch is built with the same tough design as our original best-seller; now upgraded with a larger tube for greater water capacity and faster heating. Orders are first come, first serve, so lock in your spot early for this midsize, mid-performance, mid-price kit.
No wires. No motors. Just wood, water, you, and the laws of nature.
Upgraded flow. Faster heat. Same tough build.
Built for colder temps, bigger tubs, than the OTG.
Perfect for backcountry setups, remote cabins, or backyards — anywhere you want hot water without the extra gear, engines, pumps, batteries, wires, or mess.
Estimated shipping in 5–7 weeks (We’ll keep you updated, if its built early, yours ships early.)
Limited kits available in this run. Once they’re gone, they’re gone.
What’s included:
Improved coils for more water output
Push-on connection
High-heat, high-strength push-on hoses
Quick connect to your tub, with all the connections from your tub to coil
Stainless steel attachments for your tub
What you need:
Drill two holes
Fill and chill
You got this.
