Inexpensive, easy-to-install FlexCap insulation system enables consumers to save energy and lower hot water heating costs
UCF researchers have invented an insulation system that can reduce a hot water tank’s heat loss by as much as 30 percent. Based on testing performed by the Florida Solar Energy Center (FSEC), a hot water tank can lose a significant amount of heat through its top assembly. This results in loss of heat and in turn, higher electricity costs for the consumer. Properly insulating the upper part of a tank can be challenging, and different methods for covering it can be costly, as well. UCF’s new FlexCap Hot Water Tank Insulation System offers a low-cost, simple solution for insulating and covering the tops of a variety of electric hot water tanks.
The invention is a hot water tank insulation system and methods for fabricating the system using a lightweight, flexible material that can fit around different sizes of pipe inlets, outlet and pressure relief valves and a variety of tank top configurations.
- Energy saving—potentially reduces an existing water tank’s heat loss of by 20-30 percent
- Very low cost
- Flexible and adjustable to accommodate different water tank sizes and configurations
