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 heated 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.
