For the most efficient alternative heating technology available today we offer, wood boilers, wood furnaces, wood/oil combination boilers and wood/warm air combination furnaces. All of these units can be installed in the basement of your home and into your existing chimney. Simple and easy installations make these units a must to have in your home.
Why buy our wood heating boilers and hot air furnaces? We have wood and oil combination boilers and furnaces and also wood add ons for hot water or warm air. These add-ons attach to your existing furnace or boiler. With the cost of heating oil currently at $2.75 per gallon and rising the payback to you on one of these heating units is quite rapid.


The Benjamin DO180 Wood Boiler operating in our shop and heating the shop and cabin
Our boilers and furnaces use 2/3 less wood than an outside boiler. The smoke goes up the chimney, like it would if you had a wood stove. If you have only one chimney for the install you can add a power venter or a direct vent, which will accomodate your oil boiler.
Our heating units are all UL approved and have
not emmisions problems with the EPA. The outside boilers are under deep scrutiny due to
their extremely heavy smoke issues. Some states and towns are limiting their use or banning
their use entirely. An added plus to our wood boilers and furnaces is the cost. The installation
for our heating units is significantly lower than an outside wood boiler.
