What we design, install and service.
Ground-source for a house
Heat-loss check, a written proposal, the loop, the unit and the connection to your radiators or ducts.
HousesGround-source for a small institution
Proposals written for a board, work scheduled around services or the school year.
Small institutionsThe loop field
Vertical bores or a horizontal trench, flushed and pressure-tested before it is buried.
The loop fieldService on systems we install
Flow, pressure and settings checked after the first month, and a visit each year after that.
How pricing works
Work that goes with the loop.
Air sealing and insulation advice
We tell you what to fix first so the loop can be smaller. Another contractor may do the work.
Radiator and duct changes
Larger radiators in the rooms that need them, or new duct runs where the old ones leak.
Preheated hot water
A heat-recovery connection to your water heater, where the unit supports one.
Start with the site visit.
We look at the building, the lot and last winter’s bills before we say what fits.
