Design temp: -30 degrees
Approx. 1700 sq. ft. slab on grade rural residence with heated attached garage
Boiler: Triangle Tube Challenger Boiler. High efficiency space heating and domestic hot water
Challenge: Design and build a high efficiency heating system for use in a remote location and extreme weather conditions allowing for multiple heat sources to work in tandem (propane, solar, electric, and wood burning stove to be installed at a later date)
Solution: A Tisun (Lochinvar) 250 gal tank with an internal stainless steel coil for domestic hot water production and a solar side arm coil to allow for solar heat and domestic hot water production was installed. The tank acts as a thermal accumulator allowing for multiple heat source inputs and as large buffer tank for our four (4) zones of heat through the Caleffi manifold, as well as domestic hot water through an internal coil and supplemented by the Triangle Tube challenger boiler.
