Heater Rentals - Indirect Oil Fired Heaters
Indirect Oil Fired Heaters available for temporary & emergency heat. 193,000 BTU and 400,000 BTU indirect oil fired heaters produce heat by using an oil burner…and do so simply using a 110 volt standard outlet. The tremendous output of these heaters is developed by using burner chambers originally designed to meet rigorous Canadian and European standards for energy efficiency. The flame developed by the burner is contained in the chamber, while air is pushed across the outside of the chamber, ensuring nothing but warm, clean air is produced and directed into your space. The chamber has an exhaust pipe which allows the combusted fumes to leave via an exhaust stack, much the same way as the burner in a home works. Units are compact and can go in elevators, narrow hallways and doorways.
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.
