Product details
The Lochinvar EnergyRite ERN402-A-8009 is a 400K BTU natural gas pool heater built to ASME commercial grade, sold under Lochinvar part number 100143241. It is specified with a cupro nickel heat exchanger.
Where it fits
At 400,000 BTU this is a commercial size heater, the kind used on hotel, club, municipal and therapy pools rather than a backyard pool. Lochinvar lists it for indoor and outdoor installation, so it can sit in a mechanical room or on an outdoor equipment pad.
The cupro nickel exchanger
Cupro nickel tolerates aggressive water better than plain copper. On commercial water, where bather load is high and chemistry moves around more than it does on a home pool, that is the material most operators want in the heat exchanger.
Before you order
This heater is configured for natural gas. Check the gas type at the meter, and have the gas line, venting and clearances confirmed against the Lochinvar manual and local code before installation. Installation should be handled by a licensed gas fitter.
