HTHV Heating Safety

At Cambridge Air Solutions we know that safety is not only important it’s required. Our commitment to safety and innovation are the guiding principles for everything that we manufacture and it is because of this commitment that we strive to manufacture the safest HTHV direct fired energy saving heaters available. Our HTHV heaters are “Inherently Safer” because our products use 100% outside air to heat the space.

What does 100% outside air provide? VENTILATION. Proper ventilation means superior Indoor Air Quality (IAQ). At Cambridge we have a saying, “Buildings Don’t Need to Breathe But People Do”™.


Save up to 70% on combined gas and electric energy costs by installing Cambridge HTHV energy efficient heaters. Cambridge HTHV direct gas-fired space heaters with Blow-Thru® technology are used to heat and ventilate commercial and industrial buildings where non-ducted heating solutions are specified. Our HTHV technology is recognized as the best and most energy efficient way to heat and ventilate commercial and industrial buildings in both new and retrofit installations.

The Department of Energy and energy modeling studies document that HTHV heating technology systems like our line of energy saving heaters use the least amount of energy to heat/ventilate warehouses and other commercial/industrial buildings with large open spaces.


Whether it is a mechanical contractor looking for the lowest first cost or a building owner looking for the lowest lifecycle total cost Cambridge Air Solutions’s HTHV products will meet your needs. The HTHV technology in our energy efficient heaters offers the lowest overall first cost because one piece of equipment will heat, ventilate, and destratify. With other heating technologies you have to include ventilation and destratifation equipment to accomplish the same indoor air quality goals as on Cambridge HTHV direct fired heater. And because HTHV is very energy efficient your long term operating cost and facility impact cost are drastically reduced as well.

It is important to determine the lowest total heating costs for each project. Don’t let what appears to be the lowest equipment cost determine what is important when it comes to reducing installation, operating, and facility impact costs.

Cambridge manufacturers the most energy efficient space heater on the market by utilizing HTHV technology. Our energy saving heaters are built to save costs as well for both contractors and business owners.
