Central Heating
BioHeatUSA offers innovation in home central heating solutions and a commitment to consumer education and environmental awareness. Exclusive partnerships with leading manufacturers allow BioHeatUSA to offer products that are reliable, efficient, and which promote the clean burning of carbon-cycle biomass, which is critical to lowering greenhouse gas emissions. BioHeat USA boilers are utilized by a variety of environmentally conscious organizations throughout like the New England Wildflower Society, Framingham, MA and the New Hampshire Audubon Society, Concord, NH.
HS Tarm, Scandtec and Froling Wood Boilers Wood boilers provide a convenient, safe, and environmentally responsible way to heat your home and hot water. Wood boiler owners are ensured of high heating efficiency, low heating costs, and use of an abundant, locally available, renewable fuel.
The Solo Innova (pictured here) is a wood-fired gasification boiler offering 75-80% overall efficiency. The key to this process is the high temperature reached in a second refractory-lined combustion chamber. This secondary combustion consumes the creosote and smoke that normally goes up the chimney, thereby wringing every bit of energy out of the wood fuel and resulting in a very clean burn.

Froling Pellet Boiler
The construction of our pellet boilers ensures high operational reliability, durability, and simple operation. Froling pellet boilers deliver up to 91% efficiency and can run for days on a single load of fuel.
The feed auger automatically adds the correct amount of fuel into the combustion chamber, and the quiet, built-in blower provides the precise mixture of primary and secondary air necessary for clean, efficient combustion. The only maintenance required is filling of the hopper with fuel (Automatic Feed Head available), and the removal of ash, as necessary.
Advantages of Pellet Boilers
Burns wood pellets and corn which are economical, environmentally friendly and domestic
fuel sources.
Multi-Heat boilers can be very easily incorporated into existing heating systems.
Combustion efficiency of up to 91%. Constant heating gives optimum building comfort
Simple operation via a multifunctional digital control on the front panel.
No storage tank required.
Automatic shut-off to prevent hopper burn back.
Delivered fully assembled.
Easy to position: Top flue exit and reversible doors provide maximum flexibility.
Sturdy construction features include acid-proof stainless steel (AISI 316L) in the combustion
chamber and 6mm (¼”) water cooled steel plates in the boiler interior.

Each furnace and boiler maintains even, consistent heating to heat homes as efficiently as possible. Harman's selection of central heating units is designed with homeowners in mind. Automatic temperature control and large ash pans keep maintenance to a minimum while most units easily fit into tight spaces for convenience.
Harman PF100 Pellet Pro Furnace
The Harman PF100 Pellet Pro furnace takes pellet fuel heating to its optimum level, operating automatically to give you warm, comfortable temperatures throughout your home. Simply fill the hopper with pellets and set the temperature dial on the wall mounted control to the desired setting. The PF100 will do the rest. If heat is required, the fire will automatically light and burn at the proper rate to produce just the right amount of heat. If heating demand is reduced, the Harman PF100 will reduce the fire. If no heat is required, the fire will go out and light again automatically if more heat is needed.
When the fuel in the hopper gets low the red light on the wall control will blink, telling you to add fuel to the hopper. The ash pan allows two to three tons of pellets to be burned before emptying and with the patented Harman feeder and burn pot, even high ash pellets can be burned efficiently.
The PF100 can be installed as a stand alone hot air heating system or incorporated into existing hot air systems. A chimney is not required for venting. This direct vent system can also use outside air for combustion. Dual heat exchangers are used to extract maximum heat from the fuel which will save you money.
Harman SF160 Trident Wood/Coal Boiler
The Trident Boiler is designed to burn pea, stove, or nut coal, or wood, and is available in three sizes so you can choose what's right for your home. Whether you need to heat 2250, 3200 or 4000 square feet, there's a Trident Boiler to do the job. Coupled with your domestic hot water coil, the optional electric package gives your Trident year-round duties, providing hot water all year and heating your home all winter.
