Our team recently visited a 7,900 sqft project in Camden, Maine, to perform a Messana Controls start-up.
This remarkable home consists of 19 zones spread across three different levels. Two geothermal heat pumps serve as the primary energy source used to provide hydronic heating and cooling via Ray Magic® NK radiant ceiling panels and Jaga hydronic fan coils.
The home utilizes a four-pipe hydronic system, which features dedicated hot and cold water tanks. This allows the two distinct macrozones to function independently in either heating or cooling mode. Furthermore, we’ve integrated NTI boilers to ensure a consistent supply of domestic hot water and serve as a reliable backup heating source.
The residence is also equipped with an Energy Recovery Ventilator (ERV) for enhanced air quality. For the winter months, two humidifiers have been installed to maintain optimal humidity levels, while a single dehumidifier ensures comfort during the summer.
