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.
Quality product, nicely assembled and timely delivery. Unbeatable price too! This switch exceeds in rating and will perform in many applications.
