Product Overview

The Jandy Hi-E2 350K BTU Natural Gas Pool and Spa Heater combines a 350,000 BTU/h input rating with 95% thermal efficiency for properly sized residential and commercial installations. This ASME-certified configuration uses a copper primary heat exchanger and a cupro-nickel secondary heat exchanger to recover heat from combustion gases. Dual thermostat controls support separate pool and spa temperature settings, while its compact cabinet provides flexibility for professionally designed equipment installations.

Compatibility

Confirm natural gas availability, gas-meter capacity, electrical service, and circulation flow before ordering. This model requires 115V, 60 Hz power and a heater flow range of 30–100 GPM. Match the heater to pool size, desired temperature rise, climate, and operating schedule. Maintain water chemistry within Jandy’s requirements to help protect the heat exchangers.

Installation or Upgrade Context

A qualified professional must evaluate gas piping, combustion air, venting, service clearances, and condensate disposal. Both indoor and outdoor installations require condensate drainage. Indoor venting materials and routing must follow the installation manual. Replacement projects may require changes to existing plumbing, electrical connections, or exhaust arrangements.
