Excuse me if I drool a little, but you may too when you take a look at this install. The Froling will be heating a 6000 sq ft educational interpretive center at Deep Portage (DP) in north central Minnesota, an older building with poor to fair insulation, windows and doors. It will replace two LP hot air gas furnaces, which remain as backup units. It also will provide DHW. The Froling was installed in its own boiler shed adjacent to the building, which also houses a 1600 gallon hot water storage tank. Domestic hot water is provided from a standard hot water heater which is now equipped with an integrated double wall heat exchanger and mixing valve. The tank can be heated to as high a temperature as the Froling will provide, and the hot water is mixed down to 120F for domestic service. With the 1600 gallon boiler hot water storage tank, there will be plenty of hot water, and DP also expects to be firing the Froling during the summer, perhaps once per week, to provide DHW. This winter I should be able to do some temperature measuring and data logging and provide a performance report. And I am excitedly awaiting the opportunity to put the Froling through its paces. The installation finished yesterday. The Froling is operating, the system has being brought up to full temperature, and all components are in operation.
