Thermal storage underfloor heat
Use the heat-storing properties of the earth
![]() |
Heat-storage systems served on off-peak rates must be properly installed to be capable of storing adequate heat to warm the space during the maximum control period allowed by the rate. A sand bed that is 6 to 12 inches deep—with properly placed insulation beneath the sand bed—helps ensure this capability for underfloor systems. |
Here's how it works
Before the cement slab is poured, electric cables or preformed heating panels are buried 4 to 12 inches deep in a bed of sand. The cables or panels charge during off-peak hours when our electric rate is roughly half our standard residential rate and create a heat reservoir in the sand and the earth around it. The stored heat can be used to warm a new home or addition, garage, workshop, business, or warehouse space.
