Central Domestic Hot Water Inefficiency Statistics

Did you know that of all the energy that is input into a central domestic water heating system only about 30% is actually used?

70% of all the water heating energy is lost.

30% of the energy loss comes from the pipes in the recirculation loop losing heat. The same amount of energy you actually use is equivalent to the energy lost from the loop.

Enovative's demand pump control system - D'MAND KONTROLS(TM) can reduce the energy lost from the recirculation loop by 55%! go to www.enovativegroup.com to learn more about demand pumps and controls.

The source of the statistics shown above comes from a study on multifamily hot water ditribution. Research was done by Heschong Mahone Group (HMG) under the California Energy Commission PIER program. Click here to download a presentation on this topic by HMG.
