The 5 Series water to water GSHP with OptiHeat technology is a high temperature unit that is the geoexchange solution for boiler replacement. It is capable of delivering 65°C leaving hot water, which is perfect for radiators, underfloor radiant applications, overfloor radiant applications and fan coils.
A typical water to water GSHP is limited to water temperatures around 55°C which can make replacing fossil fuel (gas, wood, diesel etc) boilers difficult. The 5 Series with OptiHeat has been designed specifically to meet these higher temperature requirements and makes upgrading to a WaterFurnace geoexchange system easier. It utilizes an additional heat exchanger to divert excess heat and reinjects it into the system, creating higher exiting water temperatures and optimum compressor operating conditions. Smaller loads are required and result in the ultimate in efficiency.
The 5 Series with OptiHeat represents some of our best features and efficiencies. Its advanced components offer a level of comfort and savings that are far greater than any ordinary system and among the geoexchange industry’s highest.
