Three-Element Water Heater
Three-element water heaters are less power hungry than traditional two-element heaters. The three elements are less powerful and require fewer watts at any given time, which is particularly important during peak morning and evening periods. Even though it heats water more uniformly, it can supply the same amount of hot water as a traditional water heater of the same capacity.

The top element works alternately with the two other elements to heat water in the upper part of the tank.
The middle element works when needed to heat the water over a short period of time.
The low-power bottom element, works almost constantly.
Please note that the Loi sur les maîtres mécaniciens en tuyauterie [act respecting master pipe mechanics] requires that water heaters be installed by a certified member of the Corporation des maîtres mécaniciens en tuyauterie du Québec (CMMTQ).
