Christina Keegan and I had a fantastic time building this one. Our hosts are quite serious about keeping their environmental footprint low and using local wood fuel so they hadn't even had the house for a day before we were on our way east to get them off using the massive old fuel oil furnace in the basement. They still aren't fully moved in, but their kitchen is warm!

We got to use beautiful stone from an ancient foundation on the property and nice sharp rubble and sand from a quarry right across the street. The guys from the quarry didn't even charge us for delivery, they just brought their big loader up the driveway and dumped stuff off for us.

The concrete floor of the sunroom in this old farmhouse supports a much larger mass bench than the suspended wood floor of my doublewide trailer at home so even before the cob has dried the mass bench is keeping this whole end of the house warm using little wood scraps and sticks from the yard.

The Liberator is currently the only UL listed, EPA approved rocket heater in the US. It burns scrap wood or pellets (without needing electricity). We've been testing the Liberator at my house for about 5 years now and have done several videos on this channel discussing its plusses and minuses. You can get one here [ Ссылка ]
