The 510U series is well suited for residential/commercial applications such as small
restaurants and beauty salons. Indoor models include an integrated temperature
controller. A remote control is included as a standard feature for outdoor models.
Utilizing commercial-grade copper alloy for the heat exchanger tubing, the 510U
series is also suitable for heavier-residential usages such as combination space
heating and domestic recirculation systems.
