Ground Source Heat Pump systems consist of three main components: the ground loop, the heat pump itself, and the building side.
A good design must take care of the whole system, matching the components in such a way that the most effective operation and the highest comfort may be achieved. If a contractor uses a "rule of thumb", RUN!!
We technically match soil conditions, heat and coolings loads in the designs of our systems. This results in the most efficient installation and operating costs.
