We had a great time visiting a Hyalite Custom Building project in Bozeman, Montana!
This unique 15-zone hydronic system designed by SE Engineers
and managed via Messana Controls; utilizes a radiant ceiling, radiant floor, and Jaga fan coil units for heating and cooling.
The 3,400 sqft home from architects, Thruline Partners, utilizes a Water Furnace geothermal heat pump and Lochinvar backup boiler to generate heated water for the radiant floors. This system takes a unique approach and instead of utilizing a heat pump for chilled water production, it will use the geothermal well to provide year-round cold water for use within the hydronic cooling system. This is possible due to the home’s passive house standards allowing for much lower cooling demands than a typical home. The radiant ceiling will provide radiant cooling while the radiant floor will be used for heating with both able to operate independently due to its 4-pipe arrangement. Lastly, Jaga hydronic fan coils were incorporated to provide supplemental cooling when needed along with a Zehnder ERV with a hydronic pre-heat/pre-cool coil for ventilation.
