Why this unit
The 300A11 is proof you do not need the flagship to beat a gas bill. Dual-capacity compressor, forced-air heating and cooling, and partial hot water generation from one affordable cabinet.
At 22.4 EER and 4.3 COP it still delivers three to four units of heat for every unit of electricity it draws, which is the whole point of geothermal.
Best for: Budget-conscious projects that still want real geothermal economics.
- Dual capacity at a value price
- Heating, cooling, and partial hot water in one unit
- Low-GWP refrigerant
- Aurora controls platform
