Features
| HIGH ENERGY EFFICIENCY |
| High Energy Efficiency: Up to a 400% efficiency (COP up to 4) significantly reduces energy bills compared to traditional systems. |
| The HPX™ has an advanced temperature control capability to vary its output ensuring a consistent indoor temperature with less temperature fluctuations. |
| Outdoor reset function automatically varies the outlet water temperature to further enhance comfort and efficiency. |
| Enhanced Vapor Injection (EVI) design increases efficiency, lowers ambient temperature operating range to as low as -22°F/-30°C, and increases maximum supply water temperature. |
| REFRIGERATOR QUIET OPERATION |
| Compared to traditional heating and cooling systems, the HPX™ operates so quietly it can be likened to the sound emitted by a residential refrigerator. 38-53 dB operational sound level. |
| ENVIRONMENTALLY FRIENDLY |
| Air-to-water heat pumps use renewable energy from the air to heat a home. This means that they produce fewer greenhouse gas emissions than traditional heating systems. |
| Enhanced Air Quality: No consumption of fossil fuels means no CO2 emissions. |
| EASY TO INSTALL AND SERVICE |
| Contractor-Friendly Monobloc Design: Refrigeration licenses not required for installation. |
| Easily connect to North American thermostats with 24V AC interface. |
| Increased Reliability: With fewer moving parts than traditional heating systems, the HPX™requires little maintenance and is less likely to break down. |
| Flow-proving and high limit safeties built-in. |
