Heater Rentals - Indirect Fired Heater
Indirect Fired 1,000,000 BTU heaters are available in natural gas or diesel fueled versions. Built to Canadian standards for efficiency, pushing over 13,000 CFM, these heaters are still narrow enough to fit through a standard door. For maximum efficiency (as with many of our heaters) it is recommended that air is recirculated in the space, rather than using 100% outside air…doing so can reduce fuel consumption by half. 1,000,000 BTU’s requires approximately 7 gallons per hour of fuel, On Site Energy rents temporary double wall UL Listed fuel tanks ranging from 250 gallons to 2,300 gallons capacity. Indirect Fired 400,000 BTU heaters provide clean heat using only a 110 volt outlet.
Generator sets and power cable can be utilized to provide turnkey contained heating systems on an emergency or planned basis. Heater rental solutions available 24/7/365 from any of our 3 branch locations, serving tri-state NY, NJ and CT areas and our Austin, IN branch serving the Midwest USA.
