Customer Success Stories
The Apollo heat pump system is very efficient, quiet, and easy to install. It stands out for its clear design, well-organized components, and advanced features like a touchscreen and remote monitoring through an app. It also allows precise temperature control and includes an electric backup for very cold conditions. Overall, it's a reliable and practical system.
The Heat Pump is impressively quiet; I can hold a full conversation while standing just three feet away from it. Because it's a DC inverter unit, there are no hard starts—it just ramps up smoothly from a few watts. It even handled outdoor temperatures in the single digits without any issues.
Heats my home nicely and economically. The cold weather does not seem to affect the pump. Overall I'm very happy with the system. The techs have been very helpful whenever I have had questions regarding installation, etc.
Since installing the Apollo heat pump, our energy bills have plummeted. It pulls heat right out of the air outside, even when it's freezing, and uses a fraction of the electricity our old system did. It's incredibly efficient
I was skeptical about a heat pump in our cold climate, but the Apollo proved me wrong. It consistently delivers strong, comfortable heat to our entire home, even during the deepest winter freezes. It's a truly robust system
Upgrading to the Apollo air-to-water heat pump was the best decision for our home. It integrated perfectly with our existing radiant floor heating. It runs quietly outside and provides perfectly even, comfortable heat inside
You can tell just by looking at the Apollo unit that it's built to last. It handles the elements outside without a problem and operates surprisingly quietly. It gives us total peace of mind knowing we have such a dependable system

When we built our house in 2021, we chose an electric boiler for our radiant floor heat system. It worked great but we averaged about 170kW of power per day in winter and were shocked by our electric bills even after switching to a time of use plan. Finding air to water heat pumps was something I wasn't familiar with but we found others in our cold mountain community that were using them and extremely happy with this relatively new technology. Settled on this Apollo unit based on price and great reviews. Installation was straightforward and we're now using about 50 kW of power per day AND keeping the house a little bit warmer. Went from a 150 amp breaker in our panel down to a 30 amp breaker, and can run this system with our standby generator when needed, too. Extremely happy with our decision, the unit is very well built and MBTek has been great to work with.

Easy diagram to understand how to hook it up. Customer support was great. just ordered some 1.5 ton fan heads to cool house in the summer.

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!
Update:
Now it's installed and running.
Pipe installation was very simple, only complicated by the positioning of the buffer tank. Turned it on and it ran with just the defaults set. It's silent - only audible within 3'. Heats the buffer tank (50gl) to temp in under 30mins (previous gas heater took ~40mins).
The instructions for the wiring took a little educated guesswork, but everything worked first time and it responds correctly to the house thermostats and the water temp settings.
Now we're attempting to add a DHW indirect tank as the old gas unit has just sprung a leak. Expecting great things.
