Requirements for Heat Storage Appliances

Space Requirements

• With the exception of electric furnaces, heat storage appliances typically need to meet space requirements for safe operation. For instance, the Department of Energy website states that electric baseboard heaters must be at least 3/4 inch above the top of the carpet. Keeping clothes and other combustible materials several feet from baseboard heaters and other high-energy resistance appliances is also necessary to ensure safe operation and maximum efficiency.

Control Requirements

• All heat storage appliances are controlled by some type of control panel and gauge that determine the output for each appliance. However, these control systems only partially determine the effectiveness of the system being used. Other factors also influence the perceived output of the appliance. For instance, the U.S. Department of Energy notes that rooms with individual control systems should be insulated from rooms not heated to ensure maximum efficiency and capacity.

Efficiency Requirements

• Energy efficiency is another major concern in the home heating appliance industry. In some states, concerns over energy efficiency has resulted in laws that require manufacturers and installers to meet minimum efficiency requirements before heat storage appliances can be installed. For instance, California requires that radiant heat devices emit heat at a coefficient of 0.05 or less to meet state codes.

Installation Requirements

• Heat storage appliances also are required to meet the state's minimum installation standards. For instance, in California, the attic must be ventilated in accordance with manufacturer's standards for radiant heat to avoid fire hazards. California requires 1 square foot of vent area for every 150 square feet of attic space. Requirements vary by state.
