Pro-Fab Cozeburn Features:

The Cozeburn is available in four sizes and offers both Mild Steel and Stainless Steel models. These multiple models cater to any residential or small business heating load and are equipped with several ports for multiple hookups. The Cozeburn is ideal for heating houses, shops, small greenhouses, pools, hot tubs, garages, sheds, and domestic hot water.  The Cozeburn Outdoor Hot Water Furnace connects directly into your existing heating system in your home, shop, greenhouse, or other application. The Cozeburn is designed with a central firebox surrounded by a large capacity water reserve. The corrugated firebox top provides maximum surface area for the most efficient heat. After the water is heated, it is channeled to your home’s heating system through underground insulated pipes.  

In your house, the hot water from the furnace may be used for several applications. The hot water line is typically connected to your hot water tank through a heat exchanger, providing all your domestic hot water. The water is then channeled into the existing radiant or forced air heating system. Depending on the application, a water-to-air heat exchanger can be installed to direct the heat into your heating system. The Cozeburn is installed in conjunction with an existing heating system, which remains connected as a backup system.  

Heat is thermostatically controlled on the furnace by setting the aquastat to your desired temperature, ensuring even, consistent, efficient heat. The Cozeburn is equipped with multiple hookups, allowing you to heat several buildings at once.
