Great heater and thee bypass is an exceptional addition. Much better than the Pentair Mini Mx NT we replaced.
Fast response
Works amazing
simple equipment to operate!
Great only owned a few weeks.
Great experience
I had a similar 400btu heater made by Jandy, prior to replacing it after 9 years of excellent service. This new model did not improve the NOISE level of the heater, and it takes a bit longer to heat up the same pool. I was hoping that after 9 years, Jandy would have come up with a much improved heater. Prices are now twice as much too.
We love the new bypass valve in the heater! With the water only flowing by the exchanger when the heater is on, we’re hoping to get more than the four years we had with our previous heater (same model). Nice improvement.
Best heater in the market, easy to install and easy to operate
