Things to Know About Heat Drying

Heat drying systems have earned a place in the water damage restoration industry because they greatly increase evaporation rates and speed the drying process. More and more restorers are adding heat systems to their drying equipment arsenals. The science taught in Water Damage and Structural Drying classes taught applies to heat drying as well as dehumidification.

dehumdifiers aren’t needed

By itself DrySmart creates a high energy, low relative humidity atmosphere with a continuous air exchange. Using dehumidifiers in this environment will be of negligible benefit.

The more air movers the better

Air movers, Injectidrys, and other auxiliary equipment transport heat energy to the wet materials and carry away evaporated moisture. Once in the atmosphere, DrySmart’s system air exchange removes the water vapor. In setting up drying equipment, techniques and science learned in water damage and structural drying classes still apply.


The higher the temperature the faster the drying but the temperature need only be raised enough to assure the fresh, outside air has a low R.H. when ducted into the building. In most cases a temperature in the 90s is sufficient. Only an 18° F temperature rise is needed to double the evaporation rate.

The drying starts within minutes

As an open heat drying system, DrySmart immediately provides an advantage over dehumidification. Dehumidifiers can take 12 to 24 hours to create a favorable drying environment. DrySmart creates a favorable environment in minutes. Its blowers replace the structure’s dank, humid air with fresh, hot, low relative humidity air at a rate of over 4,000 cfm.  Time is of the essence. The longer the materials sit wet, the deeper the moisture will penetrate and the more extensive the damage.

Heat drying doesn’t damage building materials

At typical drying temperatures, heat is innocuous. Consider that clothes dryers operate at 125-130°F and hair blow dryers at up to 160°F.


Over drying is when the material’s EMC (equalized moisture content) is dried to a level below what is “normal.” Dehumidifiers, as well as heat systems, can overdry. Overdrying is a restoration management issue.

The DrySmart is easy to set up, reliable, and very powerful. Its results on drying structures have been nothing short of phenomenal. My company performs well over 1,200 water losses a year and before last year had never dried structures with convecti…
