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 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.
