Solar Water Heating Energy Self Assessment

Summary

The solar water heating calculator estimates the equipment requirements to meet 50 percent of your hot water energy usage. Reducing your hot water needs before you consider a solar water heating system will reduce the size and cost of the system needed. Installing high efficiency water heaters, insulating hot water pipes whenever possible, repair leaking pipes and taps, and turning down the temperature on hot water heaters will reduce energy needs for heating water.
