Take advantage of Reduced Electric Rates
ELECTRIC THERMAL Storage Heating can be a great way to take advantage of utility company reduced rates for electric use during off-peak hours. These are usually evening hours and help the utilities take advantage of less used power and distribute there load more evenly throughout the day, which helps them reduce demand costs. Many times these rates are up to 70% less than the general service rates.
Many large utility companies have these programs. Black Hills Power, Otter Tail Power and Xcel Energy are three examples that have fantastic off peak rates.
Thermal Storage Systems are installed a little differently than regular in-floor cable systems. Since the hours of operation are limited the wattage per square foot needs to increase. See Danfoss Sand Bed Application Instructions. Once attached to the foam the cables need to be covered with 4”-8” of sand.
Remember to front dump the sand if using a skid loader and only drive over the base of sand NOT the cables. As a rule of thumb wattage needs to increase by 30%-40% per square foot depending on the number of hours it can run. It is also very important to make sure the perimeter is insulated as well. There are various ways to insulate the perimeter, one of the best is by using a piece of 2” rigid insulation laid against the inside edge of the footing down to the insulation on the floor and cut at a 45 degree angle at the top. This method gives you a totally insulated system that prevents frost and cold from penetrating the foundation and reducing the efficiency of your storage system.
