High Efficiency and Velocity Gas Fired Space Heater - Cambridge S-Series


Designed as an ultra-efficient, high-impact heating solution for warehouses and factories


Employees in high-bay facilities should have the opportunity to operate in comfortable workspaces with even heat and clean air. Make the choice to create a better work environment for your team by utilizing Cambridge’s S-Series energy efficient large industrial space heaters.

Cambridge High Temperature Heating & Ventilation (HTHV) Space Heating Systems are designed to meet a building's heat and air load requirements while being incredibly energy efficient. Our unique blow-thru design, with 160°F maximum temperature rise and discharge temperature, delivers more usable heat and thermal comfort with minimal temperature variation throughout the heated space. This commercial/industrial space heater is 20% to 70% more energy efficient than all other types of indirect and direct gas-fired systems used to heat large commercial and industrial buildings.

Discharge air from the S-Series HTHV Heater creates a large volume of fresh, warm air flowing throughout the building which eliminates higher ceiling temperatures and uncomfortable drafts. The S-Series Heater utilizes 100% fresh air to dilute contaminants generated within the building. This virtually eliminates air quality problems associated with infrared heaters or conventional air heating systems that recirculate indoor air.

Retrofitting your boiler, infrared or recirculation (80/20) heating systems with the S-Series HTHV not only brings your employees the fresh, warm air they need, but also brings significant operational cost and energy savings.


The first step to reducing your facility's carbon footprint is to use energy-efficient products.

HTHV (High Temperature High Velocity) technology in our Blow-Thru heaters allows these industrial space heaters to efficiently heat your space with a smaller design, compared to a conventional draw-thru make-up air heater. As a result, the Cambridge S-Series are up to 70% more energy efficient than all other types of indirect and direct gas-fired systems that are typically used to heat large industrial and commercial spaces. 

Saving energy with your heater means a corresponding reduction in carbon dioxide emissions as well as a cost savings on operational costs, especially at an Industrial scale over the lifetime of the unit. 

Engineered solutions + application design assistance make for a better end result.

Cambridge Air Solutions is the preferred choice for high-efficiency heaters for industrial and commercial spaces—warehouses, manufacturing plants, aircraft hangars, indoor recreational facilities, and more—all due to the proprietary features of our engineered large industrial heaters of our S-Series product line. Our expert teams can support you to design for specific applications, run heat loads and compare energy usage to other technologies on the market.

Premium equipment that's built to last.

Cambridge large industrial space heaters require less maintenance and are built to last - often decades longer than our competitors. Our Blow-Thru® design means critical elements like the motor are located in the cool air stream to extend the product's lifecycle. For added reliability, Cambridge offers an industry-leading warranty package: two years for the commercial space heater and five years on the Cambridge burner.

The Cambridge S-Series space heaters are smaller and more lightweight than other HVAC systems and are available with multiple mounting options for an easier installation process.

Product Flyer



High Temperature Heating & Ventilation (HTHV) is a technology class of products established by the Department of Energy (DOE) with the goal of increasing the energy efficiency of heating equipment throughout the US.  By definition, HTHV technologies are certified to a discharge temperature which is greater than or equal to 150°F and a temperature rise greater than or equal to 140°F and also has the ability to both heat and ventilate commercial and industrial structures.  These energy-saving products provide more than just heating. They also provide ventilation, and temperature destratification from the same piece of equipment.

HTHV products are the safest, most energy efficient way to heat. Cambridge’s HTHV products have the lowest total cost of ownership when compared to other heating technologies, especially when compared to standard efficiency gas unit heaters. Our HTHV products have been proven through both a DOE study and our own building studies to save between 20% to 70% on energy depending on the building, location, application, and installation.
