In 1961, PVI began building commercial, institutional and industrial water heaters. PVI is the only ASME-code water heater manufacturer who builds pressure vessels and heat exchangers from duplex stainless steel, AquaPLEX®. Once finished, the tanks are naturally immune to corrosion in hot potable water and require no supplemental tank linings or anode protection systems giving our water heaters superior reliability and product longevity.

Our water heaters can be configured for any common energy source including natural or LP gas, oil, boiler water, solar, steam, electricity and waste heat. Water heaters range from instantaneous, on demand water heating to storage water heaters with pressure vessels from 150 to 4500 gallons. Many products are “engineered-to-order” to exactly match the requirements of the application.
