A mechanical room that sets the bar high — installed by Balance Point HVAC in Rainier, WA!
This 4-bedroom, 6-bathroom, 8,469 sqft home features a sophisticated 4-pipe hydronic system, designed by Positive Energy and managed seamlessly via Messana Controls.
At the core is one mBox hydronic controller paired with three mZone12 zoning modules, orchestrating heating and cooling across 14 independent zones. Two geothermal heat pumps generate heated and chilled water, which is stored in separate buffer tanks to enable simultaneous heating and cooling in different areas of the home.
That water is then distributed to 16 Jaga Briza 22 hydronic fan coil units, delivering both heating and cooling as needed across the zones. Messana Controls also manages indoor air quality through an ERV unit, as well as humidification and dehumidification systems, ensuring complete indoor comfort year-round.
