A geothermal liquid-to-air and water heat pump is a water source heat pump that takes heat from the ground and distributes it into your home via hot air and hot water. In the summer, this process can be reversed for cold air (but not chilled water).
Nordic® TF Series
Our geothermal liquid-to-air and water heat pump is called the Triple Function Series, or TF Series. It is essentially a liquid-to-air heat pump and a liquid-to-water heat pump in a single machine. The TF Series provides hot water for radiant in-floor heat, forced air heating and cooling, and domestic hot water, all in one machine. The TF Series works on an open or closed loop system.
How It Works
Air heating and cooling are provided via an air duct system controlled from a central thermostat. When the desired air temperature is reached and the thermostat is satisfied, the unit can automatically switch to its hydronic (in-floor water) heating mode. It then supplies hot water to an in-floor heating system, swimming pool, or any other hot water requirement. The TF Series can also be set to hot water priority instead of hot air priority.
The TF Series is the perfect solution for a home that has in-floor heating in part of the house (usually in the basement and first floor) but also has ductwork for cooling the whole home and heating the second floor. This versatility makes the TF Series popular for new construction homes.
