      EVI / Full Inverter Technology

      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.

      UL Certified

      A+++ Energy Labeled

      This unit is currently one of the most energy efficient, with the potential to dramatically lower customers' energy costs. Its highest COP is 5.65, with a SCOP is 4.88. Our high-efficiency DC variable frequency heat pump uses over 30% less energy than other air source heat pumps.

      Heating / Cooling Time

      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.

      All-in-one PUMP STATION

      Because the heat pump itself is only one component of the hydronic installation, the entire system may rapidly become intricate and costly. The APOLLO Pump Station simplifies the entire process: Connect your heat pump + heat exchangers (fan coils, baseboards, radiators) to the Pump Station and you're ready to go.

      Included in the Pump Station:
      • Water Pump
      • Heat pump controller
      • 4KW emergency/booster Electric Heater
      • Expansion tank
      • 3-Way motorized valve
      • Sensors
      • Wiring box

      Just got it. Uninstalled.

      Unit looks well built and was well packed for shipping. I’ll update my review when I’ve installed.

      Looks like good unit, Long wait!

      Waited several months for delivery of 3.5T unit due to shipping issues and COVID lockdowns.
      Allen and others at MBTek were patient and as helpful as they could be with something outside their control.
      3/4 of my energy bill is for heating between Oct and April. Hoping for a slight overall reduction - it'll depend on future gas prices.

      Unit arrived mid April when my radiant floor system goes dormant until Oct. Lots of time for installation!

      Will update later when it's actually working.
      Getting Inflation Reduction Act grants is extremely difficult - there is no local contractor prepared to take on this install so it's a DIY!

      Great Solution

      The Heat Pump has been a game-changer for me. It's taken the stress out of heating my home, and I don't have to worry about exorbitant energy bills anymore. It's definitely a must-have for anyone looking for a more cost-effective heating solution.

      Low Temps = no problem

      Got the 4 ton unit when it was available and so far so good overall. Few "gotchas" that I've worked through with the MBTek Guys and reaching out to other users. The monobloc design made this a overall simple install! Went through a few days already this winter when it was 0F outside, the electric heating element for backup was minimally used to help boost the water temp while the heat pump was going through defrost cycles.

      Good investment

      I've been using the Heat Pump for a while now, and I'm thrilled with its performance. It's the perfect solution for anyone who wants to be comfortable in their home without breaking the bank. It's definitely the best heating investment I've made.
