Energy efficiency with geothermal

Energy efficiency with geothermal

This project exemplifies energy efficiency. The building envelope is ICF, attic blown cellulose, premium windows and doors allow this 2,500+ sq ft home to be comfortably heated with a 3T nominal heat pump. The system includes a year round, domestic hot water preheat...

Still Room for Innovation

Even in a well established industry, this installation stands to prove there is ‘always room for improvement’. There are a few things that set this design apart from the status quo; Hybrid closed and open loop Variable loop flowrate Heat exchanger...
Commercial 3 Phase Geothermal Heat Pump Installation

Commercial 3 Phase Geothermal Heat Pump Installation

With this installation, inputs such as hot and chilled buffer tank temperatures, 22 room thermostats and outside air temperature are all taken into account to control geothermal heat pumps, circulating pumps and a plethora of control valves. When the heating and...
Biomass + Solar = Energy Independence

Biomass + Solar = Energy Independence

In British Columbia, nothing says local energy like a combined biomass gasification and solar thermal system to supply space heat and domestic hot water. During the low solar gain, high heat requirement months, the biomass system provides the vast majority of the...
1/4 The Energy, None of the Carbon

1/4 The Energy, None of the Carbon

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...
