The Classic: How It Works

How Heat From A Central Boiler Outdoor Furnace Gets To Your Home
- The Central Boiler outdoor furnace is located outside, typically 30 to 200 feet (but as far as 500 feet) away from your home or building, and works with any existing heating system.
- A water jacket surrounds the furnace firebox and heat exchanger, and heater water is circulated to your home or building through insulated underground pipes -- an efficient way to move heat over distances.
- The outdoor furnace is designed to work with any existing heating system. Water-to-air or water-to-water heat exchangers or direct circulation conveys the heat into the structure's forced air furnace, radiant baseboard, or radiant floor heating system. This allows you normal thermostatic temperature control.
- The outdoor furnace can provide heat for all your domestic hot water by adding a water-to-water heat exchanger. You can turn off your hot water heater and save even more money!
- The outdoor furnace has the ability to heat multiple buildings, such as a garage, workshop, shed, greenhouse, or barn -- without using other heating sources. It can even be used to heat a swimming pool or hot tub.

The Inside Story On Outdoor Wood Furnaces

The Central Boiler furnace models are engineered to be the most efficient outdoor wood furnaces available while providing the best durability, low maintenance features, and an appealing fit and finish. The Classic models are manufactured using heavy gauge carbon steel and have proven their durability over many years of service. The Classic models are available in a choice of 9 different colors with the exception of the CL 7260 and the Pallet Burner which are available in charcoal. All of the Classic models are available in a Dual Fuel Ready Model with an optional fuel burner (standard on the CL 7260 and Pallet Burner).
Central Boiler has also developed the E-Classic 2300, the outdoor wood furnace that shatters virtually every preconceived notion about emissions and efficiencies of wood heating. The 2300 has qualified for the U.S. EPA Outdoor Wood-fired Hydronic Heater (OWHH) Program and meets 2010 clean air regulation emissions limits. The E-Classic is also available in Dual Fuel Models and is available in terra brown/taupe.
