Our furnaces also have a thermostat controlled draft blower that blows in from the back and through the ash pan under the fire not through the door and over the fire. We then double insulate the furnace and cover it with 40 year warranted steel siding and trim, and will build in almost any color. These furnaces are rated at 235,000 BTU and will heat 5500 sq.ft.in the very cold climate or 340,000 BTU and 8000 sq.ft.. They will heat your Home, Shop, Hot Water and your Hot-tub if you want. One pump is included but there are hookups for another and we will add more if needed. Just make sure to request more pumps to be added when placing your order! Our small furnace weighs 1800+ lbs. without the water. We have a 20 year burnout warranty and would be proud to show you the quality material and workmanship before you buy. With Acme Furnaces you can select your colors for the roof, siding and trim at no extra charge just let us know your selection when ordering!

Things to Compare When Looking For an Outdoor Furnace

Ash Removal Made Easy

We have a 10″ tall compartment on the 235 &340 with grates to insure a total burn and ease of ash removal, no need to let the fire burn down and scoop to side to remove ash.

Greater Water Capacity

Our 235 Acme Furnaces  have a 235 gallon capacity giving you more BTUs for your money. Our 340 Furnace  340 gallons and the Acme 735 hold 735 gallons. A BTU is the amount of heat it takes to raise the temperature of a pound of water by one degree. BTU’s Explained
If you start with 55 degree water and you raise it to 180 degrees this is a 125 degree change.
Water weight 8 lbs. per gallon.

235 gal. x 8 lbs. = 1880 lbs.
1880 lbs. x 125 degrees = 235,000 BTUs
Don’t be fooled, this is a proven fact you would have to heat 100 gallons of water to 435 degrees to extract 300,000 BTUs. That’s not possible or even smart to try!
It Just Makes Sense
Wood is still the most renewable resource we have and the only one you can control the cost of.
A truck load of wood on average is equal to just over 100 gallon of propane when burnt through our controlled furnace meaning at today’s prices a truck load of wood is equal to $250-$350. Propane and Electric heat prices have no end in sight.
This alone will save much more than the price of the Furnace plus you heat your hot water for FREE saving you another $30-$60 per month.

Acme Furnace’s are an Easy Installation

We recommend a seperate Heat Only Thermostat to Control Our Outdoor Furnace

Using the exisiting thermostat(4 wires) and then adding a second heat only thermostat (2 wires, power wire and fan wire)  connected so only the fan  comes on with use of your outdoor wood furnace. When the 2 wire thermostat determines it’s time too heat the building it calls for the fan to come on and distribute the hot air from the heat exchanger.

Our Furnaces can be installed by any Heat and Cooling Company or like minded person. Having a concrete pad for your furnace is recommended. Trenching from the furnace to the build for the pipe is usually done with a small bucket excavator or ditch witch,  digging down 30 to 36 inches is recommend. Connecting the heat exchangers and the lines to the back of the furnaces is where the Heating and Cooling folks come in. Just making sure to get your supply and return line hooked up properly to the pump. Thermostat temperature control is added to set your preference for room temperature just like your forced air unit. A fresh water supply is need to fill and replenish the boiler with water. This can be done with a separate line to supply the fresh refill water to the boiler or by putting “T’ with a valve in the return line to the furnace to supply water to your boiler.  If heating your shop/garage a heat exchanger can be boxed in with a squirrel cage with a thermostat and the result is very effective for a warm place to work without getting to fancy and expensive.

Where to Place Your Furnace

This furnace is set on a 10 x 10 Concrete Pad which leaves extra walking space around your furnace and room to stand on a solid area while adding wood!

We recommend a concrete landing. This 235 Model is on a 10′ x 10′ x 3″ inch pad, it is positioned at the back of the slab where the piping comes out of the ground and connects to the Furnace using the back panel for access. We recommend at least a 5′ x 10′ for our customers, this allows you to stand on firm ground while loading your Acme Furnace. Distance from your structure may vary with Home Owners Insurance Policy. We recommend at least 25′ with the door facing away from the structure 40′-100′ is ideal.  Our pumps will handle a greater distance with consideration of the head lift. If the head lift is greater then 19′ we would most want to work with you and decide weather or not to  recommend a bigger pump and adjust the cost accordingly.

 

Trenching to lay Your Underground Insulated Pipe

Diging a trench for the pipe

So easy even the kids can help install your Outdoor Furnace!

Trench digging can be done with a ditch witch, small bucket excavator or even by hand in some cases. We recommend your underground piping be at the same depth as recommended for water lines in your area. In this picture  the ditch is 30-36 inches.

Hot Water Coil

If needed we can install 50′ of 5/8 copper coil in your furnace to heat your Hot Tub, Pool or if you don’t want to use a Side-Arm heat exchanger for the hot water you can use the Domestic coil for this also. The Hot Water Coil (50 ft. of 5/8″)  and fittings are an additional $125 and must be added at the time you place your order.
