1.5 Ton Water Source Heat Pump
Carrier Horizontal, Left Hand Return, Copper Coil, R-454B | 50WCA018LBA3BA-A
$3,836.99
A 1.5 ton water-source heat pump delivers 18,000 BTU for a small zone or a room in a geothermal home. Trading heat with a water loop instead of the outdoor air gives it consistent performance year-round, without the efficiency dips air-source units face in temperature extremes.

Outdoor air swings from below freezing to sweltering, and an air-source unit's efficiency swings with it. A water loop stays in a much narrower band, so a 1.5 ton water-source heat pump keeps delivering strong heating and cooling even when the weather doesn't cooperate — one of the main reasons geothermal and loop systems are so efficient.

It exchanges heat with water that stays near a steady temperature, rather than outdoor air that swings widely. That stability means far less efficiency loss in extreme heat or cold.
A small zone or room, roughly comparable to an 18,000 BTU air-source unit — but the exact capacity depends on your loop's entering water temperature and flow rate.
Yes. Geothermal systems use a ground loop, and water-source heat pumps are the units that connect to it. They also work on commercial boiler/cooling-tower loops.
No — these units install indoors and run quietly, with no outdoor condenser to generate noise outside the home or building.
