Introducing the NEW ES500P!
The latest addition to the ESI heater line up. Featuring an all-welded stainless steel indirect fired firebox and heat exchanger, they are a cut above the competition. Other features include steel lifting harness, heavy-duty pneumatic tires and slim design for easy site mobility and transportation, and a built in fuel tank with a 15.25 hour run time.
ESI Manufactured Heaters- The ES Series
The ES700 was first produced in 2001 and is the #1 selling heater on the North Slope. Built for rugged durability and superior cold weather performance, it is easy to see why it is Alaska’s preferred heater.

700,000 BTU, diesel fueled Carlin burner and Kubota powered generator, extended service oil pan package, new dual fuel tank design, 100% 309 stainless steel firebox and heat exchanger construction.
First produced in 2002, the ES1.5 was the logical follow up to the ES700. Same rugged, arctic tough construction but on a larger scale.

1,500,000 BTU, diesel fueled Carlin burner and Kubota powered generator, extended service oil pan package, new dual fuel tank design, 100% 309 stainless steel firebox and heat exchanger construction.
Introduced in 2007, the ES550 provides serious heat on a smaller, less fuel consuming scale to offer alternatives when the heat requirements are less demanding.

550,000 BTU, diesel fueled Carlin burner and Kubota powered generator, long run oil pan package, new dual fuel tank design, 100% 309 stainless steel firebox and heat exchanger construction.
