We were called to solve the problems and get this Geo-exchange performing as it should. This system was 8 years old, with a history of failed compressors, nuisance trips and high energy consumption. 5 commercial 3 phase heat pumps are distributed around a 2 acre facility.

Net Positive This system is net positive by more than 3,000 kWh/yr. This is thanks to a large ground mounted, grid tied, solar photovoltaic (PV) array coupled with and open loop geo-exchange heating and cooling system. These systems provide more than 12 Mega Watt...

This retrofit geo-exchange project interacts with existing building air handling units to reduce space heating loads and deliver energy at a high coefficient of performance than the original system. Heating is staged in with geo-exchange as priority and the original...

In this application, fuel oil was burned in a low efficiency boiler for space heat and, year round, for domestic hot water. Thermal efficiencies on aging boilers of this type can be as little as 50-60% meaning half the internal energy in the fuel oil is not...

Most geothermal heat pump installations produce either hot water OR air for hydronic or forced air distribution as well as domestic hot water. A triple function installation does both, it provides hot water AND air for hydronic and forced air space heat as well as...
