Product details

The Lochinvar EnergyRite ERL-402-A is an ASME commercial grade pool heater rated at 400,000 BTU and set up for propane. The Lochinvar part number is 100143191.

Commercial grade, and why that matters

ASME certification of the heat exchanger is what separates a commercial heater from a residential one on paper, and it is frequently what an inspector looks for on a commercial pool. If the specification calls for ASME, a residential heater of the same output will not pass, whatever its BTU rating says.

Fuel, location and elevation

This is the propane version. Natural gas is a separate part number, so confirm the fuel at the site before ordering. The heater is rated for indoor or outdoor installation, and as supplied it is rated for elevations from sea level to 2,000 feet. Ignition is electronic, so there is no standing pilot to relight after a windy night.

Installation

A 400,000 BTU gas heater needs a correctly sized gas line, proper venting if it goes indoors, and the clearances Lochinvar specifies. Have a licensed gas installer size and commission it.

Questions and answers

What people ask about this product, answered by our pool techs.

Is this natural gas or propane?
Propane. Lochinvar builds the EnergyRite in both fuels under different part numbers, so match the heater to the gas supply at the site.
What does ASME commercial grade mean here?
The heat exchanger is built and certified to the ASME standard. Commercial installations frequently require it, and some jurisdictions will not pass an installation without it.
Can it go indoors?
Lochinvar rates it for indoor or outdoor installation. An indoor install still needs correct venting, combustion air and clearances, which is work for a licensed gas installer.
Does elevation matter?
Yes. It is rated as supplied for 0 to 2,000 feet. Above that, talk to Lochinvar about the correct configuration before ordering.
