Cold-Weather Output and DIY Support

“I'm very happy with my air to water heat pump and want to thank Jesus and others at Mbtek for helping me get it going as a DIY'er. It's a 5 ton unit and measuring the water flow and temperature differential it's right in line with that heat production even with temperatures below 30F. In addition I've been monitoring the electricity consumption which can be used to calculate the COP and it's about 3.5 when temps are around 25-30F which I think is excellent. It's very quiet as well.”

Economical Heating in Cold Weather

“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.”

APOLLO Air-to-Water Heat Pump

★★★★★

Quiet, Well-Built, and Efficient

“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.”

APOLLO 5 Ton Air-to-Water Heat Pump

★★★★★

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.”

A Hard-to-Find EVI Inverter Option

“I picked up the Apollo 42k btu air-to-water system for my rental house recently. Finding a good EVI inverter unit is actually pretty tough and most of the hvac contractors I talked to didn't even know what an air to water setup was lol.”

Great Communication and Tech support

The tech support guy was knowledgeable. Paid for item but didn’t receive for over a month. Call and make sure item is in stock before buying on line. Good customer service.

Unbelievable quality

Great value. Quality inside the unit is unbelievable. Only downside is the instructions are vague. I knew this coming in but can’t beat the value and customer service is great.

Nice unit

Excellent, quiet, well-built, and just as efficient as hoped for

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.
