The Pentair 460763 Max-E-Therm ASME Pool & Spa Heater delivers 400,000 BTU in an ASME-certified vessel - the configuration required by code for most commercial pool installations.

This model combines two heavy-duty specifications at once. ASME certification covers the pressure vessel for commercial service, and the cupro-nickel heat exchanger handles salt-chlorinated water and the aggressive chemistry typical of high-bather-load commercial pools, where a standard copper exchanger would corrode.

The Max-E-Therm platform is known for fast heat-up and compact footprint. At 154 lbs it remains a manageable install despite the commercial-grade construction, and it runs on standard 120/240 VAC service.
