We Have the Proof

Every manufacturer of gas-fired unit heaters, boilers, infrared heaters, air turnover systems and direct gas-fired air heating equipment says they have an energy efficient design that costs less to operate. They talk about heat exchanger efficiencies, burner efficiencies, heating people not air, re-heating air, not re-heating air, stratified air, Blow-Thru® heaters, max temperature ratings and the list goes on. All of this information is true, but what does it mean in terms of cost per sq. ft. to heat a large commercial or industrial building? What type of space heating system really is the most energy efficient for your facility? Who has the "Proof" to back up their claims?

We have the documented proof through our unique heating studies program that includes a growing list of over 200 onsite building studies from the past 10 years.

In each study, we measured, tracked and documented heating/ventilating system performance under actual cold weather conditions for an extended period of time. This program includes onsite studies for both Cambridge technology and other industrial space heating systems.

Temperature loggers document balanced temperatures throughout buildings heated by Cambridge with no high ceiling temperatures from air stratification or cold dock door areas. Best of all, utility bills show up to 70% savings with Cambridge space heaters versus other types of heaters. A Sample Cambridge Heating System Study is shown below.
