WHY NOT HAVE BOTH! Supply Hot Water to Kitchens and Bathrooms

Introducing the newly manufactured COMBO I CORN MULTIFUEL FORCED-AIR FURNACE BOILER, 70,000 BTU/Hr, possessing both forced air heat as well as hot water for kitchens and bathrooms as well as hot water circulating heat. This auction is for a COMBO I:Color>

Note LEGS in Matte Black are $150 extra, ... otherwise you can just rest the unit on the floor, or build your own pedestal base (or use concrete blocks). All ACCESSORIES are charged out separately and you can see them in the OPTIONS paragraph below.

The COMBO ICOLOR=blue> can be used as a free-standing stove to blow air out the front or the top. Or you can use it as a furnace and connect it to your ductwork. You connect to your existing ductwork by removing a top louver-plate mounted on the top of the furnace and inserting a duct stub take-off. COMBO I will heat your Domestic Hotwater as well as providing Forced-Air out the front and top (ductable). For COMBO I:Color>, the hot water coils may also be connected to your domestic hot water tank thus providing hot water for domestic consumption for kitchens and bathrooms. If you elect not to use the hot water coils, then you can cap them off on the side of the furnace so they do not show. But if they are there, you might as well use them to heat your hot water for kitchen and bathrooms.

The COMBO II:Color> can have the hot water coils piped directly into the boiler, thus eliminating the need for the boiler to fire up and only the circulating pump will be needed. COMB II has a NEW Secondary Heating chamber (100% STAINLESS STEEL) and to get it add $2000. COMBO II normally has at least two of three ForcedAir louvers plated-off. These louvers are found on the front and top of the machine. See below under description BOILER BOOSTER a more detailed description of how this COMBO II unit can pre-heat your boiler water.

Note: MODEL 3Color> containing 165,000 BTU/Hr is also available for significantly more money, ask for details. All models are multi-fuel burning devices.

All three models are nultifuel and will burn all kinds of biomass seed material such as corn, premium hardwood wood pellets, big red winter wheat, etc. See our add-on features that will better enable you to burn wood pellets. We have a POWER-OUTAGE Module that can be added to this unit ... a handy feature to have. Supplies are limited as we have limited the purchases for our warehouse for this heating season. The manufacturer recommended selling price or MRSP is $4,485 and you are welcome to call us.

    For more information or questions, call us at 1-319-298-0500.

WOOD PELLET burning customers are recommended to do both of the following:

(1) Buy the AUGER IMPROVMENT that has the safety gap welded closed as well as two right-angle ticks welded to the end of the shaft. These auger-shaft improvements will eliminate the crushing of wood pellets and prevent them impacting or jamming the rear of the auger shaft.

(2) Install the REAR-MOUNTED FLUE EXHAUST FAN KIT that will enable you to convert your positive-draft corn stove into a NEGATIVE DRAFT and allow you to burn multiple fuels such as wood pellets without hazards. This Kit will replace your positive draft fan inside your corn stove that pushes air and flue exhaust through the combustion chamber and out the flue exhaust pipe. Postive draft systems can push hot flue exhaust gases through the hopper bin if there is a flue exhaust pipe blockage or restriction... thus creating a HOPPER FIRE!!! This is a greater danger when burning wood pellets as they ignite at a lower temperature than corn. Get rid of your old postive draft flue exhaust fan and replace it with this rear-mounted Flue exhaust fan. The kit comes with the fan, take-offs, wire extensions and connectors, plate-off, fresh-air take-off, fresh-air damper.


All homes have a hot-water heater and the option exists to route the hot-water coil into your hot-water heater and heat your water for domestic use in the bathroom and kitchen. Do not forget that you spend energy heating your hot water heater and you can save money there also if you buy our unit. It is simple to install. You will receive instructions in the Operators Manual and Technical Instructions on how to do this.


Not only will the Hot Water Coils heat your water for hot water domestic use in kitchens and bathrooms, they can also boost your boiler heating capacity and reduce your burn time on your boiler. For those installations planning to boost your boiler heat, we recommend hooking the hot water coils in series with the boiler. The Combo II has a NEW SECONDARY Heat Exchanger, stainless steel, around 10 gallons, and is an upgraded model from the old Combo I. This secondary heat exchanger included in COMBO II is required when you are using the unit as a Boiler Booster. The heated hot water output line from the COMBO Unit should input to the cold water return to the old existing boiler right before the main boiler circulating pump. Your main boiler circulating pump will draw (pump) the pre-heated, hot water from the Combo unit into the main boiler resevoir. Your main boiler resevior water is now pre-heated. Your main circulating pump will then pump water through the boiler resevoir to the individual rooms (circuts), and return back to the COMBO corn-boiler input line. Your boiler will have to work less because it is getting pre-heated hot water fed to it from the Combo corn-boiler. The burn times on your main boiler should be reduced, if not completely eliminated, thus saving gas/oil energy. When your house calls for heat, it will only turn-on the main circulating pump. Boiler fire-up times should be significantly reduced, if not eliminated altogether. If your Combo unit's hot water line is hooked in series with your main boiler, then you will not have to duplicate boiler accessory components such as pressure relief valves, automatic air vent, circulating pump, expansion tank, fill valve, RPZ valve, etc. You should however install pressure/temperature gages in the water supply and return lines to the corn furnace in order to monitor the performance, install an automatic air vent at the highest point in the water line, and install an acqua-stat on the hot water side to eliminate over-heating. The acqua-stat will eliminate over-heating on the heated hot-water coil from the Combo unit by turning the circulating pump on when the temperature rises to a preset level, e.g. 10 Degrees above the boiler temperature level, such as 180 Degrees Fahr. The Aquastat can also turn zone valve(s) on to the coldest room(s) in the house, also referred to as dump zone(s). It is recommended installations be done by a licensed Plumber/HVAC company. After purchase you will receive a Technical Installation Manual as well as an Owners Manal that addresses the hot -water coil installtion in greater detail.

     Worried about RISING fuel prices?...well don't worry. Just buy a MULT-FUEL stove, furnace, boiler, or fireplace insert and SWITCH to another (cheaper) fuel such as CORN, WOOD PELLETS or big HARD RED WINTER WHEAT ... or switch grass, or any BIO-MASS fuel of-the-future. The latest prices are posted in bags of sizes 40lb, 50lb, or 55lb where a bushel of corn is 55lb bag. BLUE SEAL STOVE CORN is in 40lb bags. Whole corn at a farm feed dealer is usually bagged in 50 bags. Only elevator grain (corn) is bagged in 55lb bushel bags. WOOD PELLETS come in a smaller bag (40 lb), and they burn less-hot than corn or other bio-mass material.

Fresh air sources may be either room air or fresh air kit. A fresh air kit is especially recommended for newer contructed homes that have air-tight construction...as room air vacuum may be crated without it. Also inside air has impurities and is human breathed and carbon-dioxide saturated. If you buy this unit, an outside fresh air passageway is already designed into our Concentric Vent Kit. Experience in the operation of Wood Pellet and Corn Stoves we recommend you: (1) Buy our Concentric Vent Kit that has a Fresh Air inlet, (2) Non-concentric Exhaust/Fresh Air technique - remove DIAGONAL HOUSING, (3) Wood Pellet Users: buy our AUGER IMPROVEMENT II as it has the safety gap welded closed with end-ticks welded the on shaft-end and will eliminate crushing of wood pellets, (4) Wood Pellet Users should consider buying the Rear flue Exhaust Fan that is mounted on the back and will create a negative air pressure, suck the air and fumes out of the combustion chamber thus eliminating HOPPER FIRES, (5) Existing Flue Exhaust pushes air and flue exhaust out of the combustion chamber and into the flue exhaust pipe ... (can create a hopper fire when pushing out thru the hopper bin!); (6) Corn Users: buy DRY corn from sources (farmers) that dry their corn 12 to 14% moisture and who cater to corn stove owners; (7) Corn Users: use crushed oyster shell with your corn and scatter or layer it into the hopper like layering soap in the laundry machine; (8) Buy a wood-pellet or corn stove that has the capability to heat both your home and hot water...that our unit!; (9) High moisture content of corn 15% can be offset by burning crushed oyster shell and partial wood pellets. Corn Users: Everyone should consider sprinkling crushed oyster shell into their corn to facilitate a cleaner burning and less ash...even if you have 12% moisture corn.
