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.

This was the smallest purchase I’ve made so far, and whether it’s an entire system or a single part, the team at MBTEK treats every job as a top priority. Always professional. Always helpful. They’re not just a heating supply house — they’re my go-to heating experts.

Nice looking well made tank

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.

Two years ago I installed the 50kw conversion burner head onto an eight section three pass cast iron boiler. The boiler was originally set up to burn coal and wood in 1991. It is of Italian manufacture and of high quality. I converted it to burn oil in 1994. In 2021 I replaced that boiler with an efficient compact oil boiler in the house. I moved the original boiler to an outside building that is set up with all controls, water buffer storage and valving with the 200btu conversion burner head. I installed the Apollo hot water coil tank inline on the return side of the system in the house. after using and testing of this system the MBTEK system provides heat to the boiler building, the 5250 square feet of heated living space and makes all of our DHW for a 3 bathroom 5 bedroom 3 story house. In Summer it heats our pool. I set the boiler to provide 70C/160F water and all I have to do is put pellets in the hopper. Reliability is all day long.
Three things, Good Engineering, Good Quality Components, Good Service and Support.

Nice thermostat. Unfortunately comes without manual.

All Apollo fan coils are super easy to install and they works super nice

This is a quality product made with the right materials to eliminate corrosion. I will plumb it in parallel with another one of the same capacity and send pictures to more fully describe the reason for doing so.

After a period of consideration of several pellet burner conversion products I selected the MBTEK product. My research considered not only the product itself but the company behind it. I wanted a company that was going to be there when I need support or service. MBTEK satisfied my requirements and the product itself is superb. All workmanship and materials are of top quality. The install is not a typical weekend DIY. There is considerable research on the boiler to be converted and the install of the burner head with all support equipment. Safety and efficiency We heat 5800 square feet in two separate and one attached building also making our domestic hot water and heat our 10K gallon swimming pool to 90 degrees. I highly recommend MBTEK, their support people and their product to anyone wanting to use alternative bio fuels for their home or commercial needs.

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.

The quality of this unit is excellent, exterior appearance and finish are superb. The interior of the unit is as nice as the exterior. all piping is insulated, electrical wiring is organized and contained in innovative raceways, with the circuit boards located in their own space with easy access to wiring connection points.

Nice unit

we have purchased two of these unit, it is solid choice for both cooling and heating, especially for the competitive pricing. it is the better solution for replacing old fan coils.

This boiler comfortably heats 3 buildings on our property. Our home a detached garage and another shop space that my wife uses.
It is simple to operate once up and running.
Just at the tail end of our first heating season with it. Very happy with this boiler and it’s efficiency.

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.
