Main Features

Operates at Extreme Cold and Heat

Wide ambient temperature range from >-31°F to 110°F. Features include intelligent control, automatic load adjustment in different climates and environments to satisfy the demands of summer cooling, winter heating, and hot water production throughout the year.

Highly Efficient and Noise-Free

The step-less inverter compressor, step-less inverter control system, brush-less fan motor, and DC speed water pump are all components of the APOLLO EVI + DC Inverter heat pump. It not only saves energy but is as quiet as a refrigerator, producing 12dB (A) less noise than a standard On / Off heat pump.

A+++ Energy Labeled

This unit is currently one of the most energy efficient, with the potential to dramatically lower customers' energy costs. Our high-efficiency DC variable frequency heat pump uses over 30% less energy than other air source heat pumps.

50% Faster than Regular Heat Pumps

Once the heat pump is turned on, the inverter unit quickly selects the best compressor/fan motor operating frequencies. The heat pump EEV will open automatically based on heating or cooling demands. The inverters' fast heating saves up to 50% more heating time compared to traditional heat pumps.

Perfect for my house. Efficient and compact!

Large family approved. Never runs out.

As parents of three young children, we were initially concerned about switching to a new heating system. The Apollo heat pump has exceeded our expectations in terms of safety and reliability. There are no hot surfaces or open flames to worry about, and the consistent temperature throughout our home has eliminated cold spots where the kids play.

The system's quiet operation is a big plus – it doesn't disturb nap times or nighttime sleep. We've noticed our children have fewer sniffles and seem to sleep better with the improved air quality. The energy efficiency is an added bonus, helping us save for their future while reducing our carbon footprint.

We love that we can control the temperature remotely, ensuring the house is always comfortable when we return from outings. The only adjustment was learning to plan ahead for temperature changes, as it can take a little longer to heat up compared to our old furnace. Overall, it's been a wonderful addition to our family home, providing peace of mind and cozy comfort.

Consistent temp during exercises. Comfortable year-round.

As an HVAC professional, I'm thoroughly impressed with the Apollo 42K BTU heat pump. Its performance at low temperatures is exceptional, maintaining efficiency even at -13°F. The system's compatibility with various heating distributions (radiators, in-floor, fan coils) makes it versatile for different installations. Inverter-driven compressor ensures optimal energy use.

Installation is straightforward with adequate planning. The unit's low noise operation is a significant plus for residential applications. Remote monitoring capabilities are comprehensive, allowing for easy system management and troubleshooting.

One minor point to note: while the defrost function is effective, in extremely humid conditions, it may cycle more frequently. Overall, this is a top-tier product that I highly recommend for both new constructions and retrofits.

Our two-story home used to have hot and cold spots, making everyone uncomfortable. The Apollo changed all that! Now every room is perfectly cozy. During last month's heatwave, the kids didn't complain once about being too hot upstairs. Plus, our energy bills have gone down noticeably. It's been a win-win for comfort and savings.

Living in Texas, summer brownouts were a constant worry. The Apollo Heat Pump has been a revelation. It recovers quickly after power blips, maintaining comfort even on the hottest days. Its efficiency during peak hours has kept our energy bills in check. Finally, we can enjoy summer without the constant fear of losing AC!

Excited to install and test

Will update after installation and testing however I received all of the ordered items quickly and with no damage and all parts included. Fit and finish are excellent! Component all appear to be high quality. I will be linking and publishing a YouTube review and installation guide once everything has been installed.
