- A hot water tank is either on or off and has the same output of BTU no matter how much energy is required in the tank.
- The hot water tank will be on less because fewer BTU will be required due to the pre-heated water in the tank.
- The watercycle can also reduce or eliminate cold water shock in the tank.
- The extended life of the hot water tank will ensure there are fewer hot water tanks ending up in landfills.
