EVI Heat Pumps

Description

Our DC Inverter Heat Pumps deliver up to 30% more efficiency than standard models thanks to Panasonic’s variable-speed DC EVI compressor. Unlike traditional on/off compressors, the DC motor adjusts speed as needed—reducing energy use, wear and tear, and hot/cold fluctuations while improving comfort and lowering operating costs.

EVI Technology (Enhanced Vapor Injection) further boosts cold-climate performance. By injecting reheated vapor back into the compressor, EVI increases efficiency by 27–30% and ensures reliable heat output even in low temperatures.

Features

• Panasonic DC Inverter Compressor – Variable speed for up to 30% higher efficiency vs. standard heat pumps
• Brushless DC Fan Motor & PFC Control – No startup capacitor, reduced energy use, longer lifespan
• Faster Heating & Cooling – Reaches set temperature quickly, then maintains it with precise modulation
• Stable Comfort – Eliminates hot/cold fluctuations common in on/off compressors
• Lower Operating Costs – Optimized energy use reduces consumption
• Enhanced Vapor Injection (EVI) Technology – Boosts performance in cold climates by 27–30%
• High COP (Coefficient of Performance) – Reliable heat output even at very low temperatures

Pool & Spa Heat Pumps

Description

Unlike gas or electric heaters, heat pump output varies with outdoor and water temperature. Colder air or higher water temps reduce efficiency, but Arctic Heat Pumps are designed to perform even in extreme conditions.

For example, at -7 °C (19 °F) with a 104 °F hot tub, the Arctic 025ZA/B still delivers 6.5 kW of heat while using only 2.19 kW (COP 3.0). At pool temps (83 °F), efficiency is even higher. The warmer the air, the better the performance.

Equipped with a color LCD touchscreen and Wi-Fi controller, you can monitor and adjust heating, cooling, or auto mode anytime, anywhere.

Features

• Full DC inverter compressor & fan motors — variable speed operation instead of simple on/off.
• Operates in very low ambient temperatures — down to about −20 °C (−5 °F).
• Heats and cools — includes a chill mode as well as heating.
• Dual-Zone control — can manage two bodies of water (e.g. pool and hot tub) or different temperature zones.
• LCD color touch-screen controller with integrated WiFi — remote monitoring and control.
• Oversized titanium heat exchanger with spiral technology — durable and efficient for salt or chlorinated water.
• Ultra-quiet operation — sound insulated with brushless DC fan motors.
• Wide operating water outlet temperature range — up to 104 °F (40 °C), suitable for pools and hot tubs.
• Low maintenance and durable — includes hot-gas defrost, freeze protection, and weather-resistant coatings.
• High efficiency — COP ratings up to about 6.4 in favorable conditions.

Hydronic Fan Coils

Description

Whisper-quiet and ultra-thin, these DC fan coils are the most efficient way to maximize heat pump performance. Covering up to 3x the space of a traditional radiator, they provide both heating and cooling with unmatched comfort.

How They Work:

Hot or cold water circulates through a copper tube/aluminum fin heat exchanger, transferring energy to the air. A brushless DC fan distributes the air twice as far as a radiator while drawing as little as 12 watts and operating as quiet as 24 dB(A)—the sound of a whisper.

Features

• Dual Function: Heat in winter, cool in summer
• Energy Efficient: Save up to 30% over traditional radiator systems
• Ultra-Thin Design: Only 5” thick, with flexible mounting options (floor, wall, or ceiling)
• Precise Comfort: Individual room temperature control
• Quiet Performance: Advanced DC fans for low noise and high efficiency
• Smart Control: Works with wall thermostats, heat pumps, and boilers
• Durability: Hydrophilic-coated heat exchanger for long life
