Pentair MasterTemp 400 Natural Gas Pool Heater

The Pentair MasterTemp 400 is a natural gas pool heater, part number EC-462028, the largest model in the MasterTemp line. It brings the efficiency, convenience and reliability of the line in a compact package that runs quietly.

Operation is as simple as a home heating system. An LCD display with troubleshooting icons shows what the heater is doing and makes monitoring straightforward.

The compact design keeps the footprint small on the equipment pad. For a smaller pool, the MasterTemp 250 (EC-462026) is the next size down in the same line.
