2 Ton Water Source Heat Pump
Carrier Horizontal, Left Hand Return, Copper Coil, R-454B | 50WCA024LBA3BA-A
$4,216.99
A 2 ton water-source heat pump provides 24,000 BTU with the high, stable efficiency these systems are known for. At this size it's worth understanding how the rating works, because a water-source unit's efficiency is tied directly to the temperature of the water it's connected to.

Water-source heat pumps are rated by EER for cooling and COP for heating, and both figures are stated at specific entering water temperatures. Warmer loop water makes heating easier and cooler loop water makes cooling easier, so a well-designed loop keeps the unit in its efficient range. When you compare 2 ton units, compare their ratings at the water temperatures your loop actually runs.

EER rates cooling efficiency and COP rates heating efficiency. Both are stated at specific entering water temperatures, so higher numbers mean the unit does more with less energy at those loop conditions.
A lot. Warmer entering water helps heating; cooler entering water helps cooling. The rated capacity and efficiency assume specific water temperatures, so your loop's real temperatures determine real-world performance.
Compare their EER and COP at the same entering water temperatures — ideally the ones your loop actually operates at. Ratings at different water temperatures aren't directly comparable.
