Product details
The Lochinvar EnergyRite ERN-302-A is a commercial grade ASME pool and spa heater rated at 300,000 BTU on natural gas, Lochinvar part 100143227.
Commercial build
Lochinvar comes at pool heating from commercial water heating, where the equipment has to survive continuous duty in a mechanical room rather than a seasonal season. The ASME construction on this model is the visible end of that, and it is why the same heater turns up on commercial installations and on residential jobs where the owner wanted the heavier build.
The control
The control system is the part most people notice. Setup, temperature adjustment and troubleshooting all happen at one place, and the two line, 16 character display reports in words rather than numeric fault codes, so a technician is reading a message instead of looking up a table. Pool and spa each get separate control capability, and the heater is equipped for third party remote operation if it is being driven from an automation system.
This model is also cataloged as a Lochinvar Copper-Fin2 low NOx heater, so both names point at ERN-302-A. Check the rating plate on an existing installation before ordering a replacement.
