  • I would be interested in knowing a bit more about this. As a BPI home energy audit and home performance contractor the only way I know of improving the efficiency of a hot water heater is to A. Turn down the thermostat, B. Flush it on a regular basis, C. Install a power vent system. D. Install an additional thermal blanket around heater. E. Replace the unit with a heat pump assisted unit, or Geo-thermal system. Or on demand unit. I have never heard of doing anything that would make the existing heater increase to a EF of 2.
