Air to Water Heat Pump Retrofit

A Nordic Air to Water Heat Pump is the heart of this retrofitted heating and cooling system. Numerous improvements will cut the energy bills dramatically and provide comfortable temperatures throughout the year.

Net Positive Geoexchange and Solar

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...

Geothermal, Solar Combi System

This turnkey renewable mechanical system is designed to provide domestic hot water and space heating with minimal external energy input. The vast majority of space heat and domestic hot water is provided by the geothermal heat pump and solar thermal system. This...

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

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...

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...

Clean & Green Solar

Clean & Green Something I hear from time to time is that solar is “ugly”. It doesn’t have to be. By paying attention to detail and planning the installation to be as unobtrusive as possible, it can not only work well for decades and displace...

Triple Function Geothermal – The Ultimate Solution

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...

Sunshine Coast Solar Studio

The addition of a premium solar thermal system with storage, freeze and overheat protection to this small studio has brought the owners one step closer to energy self sufficiency. Innovative lineset routing, flashing and collector placement reduces roof penetrations...

Seamless Integration – Solar Thermal

Careful system planning can make your solar hot water system integrate seamlessly with your homes mechanical and potable systems, as well as its aesthetic. Isolation valving can be unobtrusive and offer superior system...

Wood Heat and Solar Thermal – Perfect Match

In Canada, our available solar profile can be 3-4x greater in the high gain months (summer) than in the low gain months (winter). For a relatively constant load such as domestic hot water, depending on load/capacity, a solar thermal domestic hot water system sized to...

Variable Speed Solar Thermal – Reverse Return Evacuated Tube

What sets this solar thermal installation apart from many others is the variable speed pump control and the reverse return collector. In periods of lower solar radiation (late/early day, winter and overcast/cloudy) and when there is a higher storage tank temperature,...

158L Integrated Storage – Where Simplicity Meets Function

The main advantage of an integrated storage solar thermal system is simplicity (which is reflected in the cost) – no heat exchanger, no pump, no controller and no glycol.  The disadvantage is the lack of freeze protection and requirement for the tank on the...

6 ton Geothermal – Residential Installation

Savings – Calculated $2,800 CAD/year energy cost, displacing 4,100 litres/year of heating oil, 12 1/2 Ton/year CO2 equivalent reduction Type – Forced air, closed loop, water to air,  desuperheater Groundloop – Horizontal slinky, 600′ of trench,...

5.7m^2 Solar Thermal Preheat, Residential Installation

Savings – Calculated $280 CAD/year energy cost, 8.69GJ/year, displacing 2,420 kWh/year of electricity, 1/5 Ton/year CO2 equivalent reduction Type – Preheat domestic hot water 80USGAL, closed loop propylene glycol, thermosyphon loop Equipment – Delta...
