Long Residence – Raymond Maine

Dealer: Hamilton Geothermal / Mike Marquis Plumbing & heating

The Long residence in Raymond Maine features a complete radiant heating system with 2″ lightweight concrete pour-over on all levels. The heating system is highlighted by (2) WaterFurnace NSW050 water to water geothermal heating systems installed by Hamilton’s Geothermal from Gray Maine. The geothermal is supplied by 1090′ of vertical closed loop with Wilo Stratos variable speed circulators on the source piping.
In addition to the radiant heat – the home also features five chilled water air handlers supplied by the geothermal chilled water system. for air conditioning during the summer months.


The Long’s also chose to incorporate a Viessmann Vitodens 100 series boiler as a back-up to the geothermal heating system as well as providing domestic hot water for their home. Mike Marquis Mechanical installed all the Viessmann equipment as well as the entire HVAC system.
The Long’s also added a Viessmann 30 tube vacuum solar collector to preheat their domestic hot water. The solar system delivers the hot water to a 80g stainless steel hot water tank.

The Long residence is another great example of Coastal Winair’s mission to integrate our new variable speed energy saving products with proven renewable geothermal heating and air conditioning technology.
