COMMERCIAL & INDUSTRIAL HEATING SOLUTIONS

For many commercial and industrial buildings that do not require space cooling, non-centralized equipment such as unit heaters provide space heating to building occupants. Unit heaters are a traditional method of providing heat in large facilities throughout the U.S. According to the DOE, unit heaters account for nearly 18% of primary space heating energy use for commercial buildings, specifically in warehouses, distribution centers, etc. Much of this space heating energy is wasted because of inefficient or outdated technologies.

Technologies that are commonly used in heating and ventilation of large open spaces are air turnover, recirculation, make-up air, infrared, unit heating, and high temperature heating and ventilation (HTHV).

High Temperature Heating and Ventilation (HTHV) Technology

High Temperature Heating and Ventilation, also known as HTHV, is a technology classification created by the Department of Energy (DOE). HTHV products provide a discharge temperature that is greater than or equal to 150°F and a temperature rise greater than or equal to 140°F. HTHV heating systems have the ability to heat and ventilate large commercial and industrial spaces. HTHV technologies are deemed to reduce energy consumption and increase energy savings in commercial sectors throughout the U.S.

Commercial and Industrial Heating/HTHV Applications

HTHV technologies have become the gold standard in heating and ventilating high-bay commercial and industrial buildings. The 100% outdoor air introduced through ANSI Z83.4 technology is designed and installed to improve the indoor air and environmental quality of the facility. Any level of required ventilation, including ASHRAE 62.1 levels, can be achieved and maintained through these technologies.

Many offerings include optional MERV13 filters added to the inlet air of this device, further improving indoor air quality. ANSI Z83.4 equipment can be installed with a minimum amount of ductwork, providing an efficient and cost-effective installation.

Additionally, HTHV direct-fired heaters can be installed indoors or outdoors or in horizontal or vertical configurations while always providing 100% fresh outside air, thus, improving the comfort and safety of those inside.

Benefits of HTHV Technologies

With the main goal of increasing the energy efficiency of heating equipment, HTHV technology provides the following benefits:

  • It reduces energy consumption significantly. According to DOE and energy modeling studies, HTHV systems use the least amount energy to heat/ventilate warehouses and other commercial/industrial buildings with large open spaces.
  • Lower total costs for mechanical contractors and building owners. Some industrial and commercial HTHV systems have the ability to provide Heating, Ventilation, and Destratification all from the same piece of equipment. This helps reduce installation, operating and maintenance costs.
  • Increase safety and comfort for workers on the floor. By using 100% outside air and direct-fired technologies, HTHV products provide a ventilation process that delivers superior indoor air quality for employees/building occupants.

Specs & Techs

What is the difference between HTHV products and 80/20 unit heaters?

For years, HTHV direct-fired heating systems and traditional 80/20 direct-fired units have been the heating solutions used for new construction and retrofit projects throughout the U.S. The largest difference between HTHV products and 80/20 units are the indoor air quality (IAQ) that the systems provide.

Good IAQ includes comfortable temperature and humidity, adequate supply of fresh outdoor air, and control of pollutants from inside and outside of the building. The performance and safety standards set by the American National Standards Institute (ANSI) are z83.4 for HTHV 100% outside air non-recirculating direct gas-fired industrial air heaters and z83.18 for 80/20 recirculating direct gas-fired industrial air heaters. Thus, HTHV direct-fired 100% outside air technologies improves IAQ better than 80/20 direct-fired technology.
