The rear of the Anthrakings are double wall, the sides use the insulation and jacket with a partial deflector plate forcing the air up the tubes. We tested the furnace to zero clearance on the sides and rear, and 4" off the exhaust of coarse everything falls under local code for solid fuels. But I can say most heat goes out the top of the furnace into the home not the chimney. I am looking at possibly a domestic coil tempering system above the front door but I have to do some testing to see how it works . With all the tubes they have a lot of surface area for a small footprint. We finally have our brochures done for the boilers and furnaces and they are being sent out to the interested dealers.EarthWindandFire wrote:Hitzer recently updated their website with information about the 710 furnace.

I also noticed that Leisure Line now also offers an optional cold-air box for the Anthrakings. Does anyone know if the Anthraking is double-walled like the 710 or just insulated on the sides?
Also there is a filter box option that holds a standard 20" X 1"filter it can be made to easily accept a thicker filter if someone desired it can also be assembled to multiple configurations . Thanks,Dave
