A Sustainable Option

The use of a single three-element water heater won’t make a huge impact on Québec’s power system. But if hundreds of thousands of households used three-element water heaters, the collective electricity demand would be better balanced thanks to lower power demand at peak periods.

Choosing a three-element water heater is an environmentally responsible choice that is part of a broad effort to use Québec’s hydroelectric resources more wisely.

Collectively, we use a lot of energy to heat water

Electricity consumption varies according to demand at various times of the day and different times of the year. Collective demand is particularly high during peak morning hours, between 7 a.m. and 11 a.m., and in the evenings between 5 p.m. and 9 p.m. During these periods, the average Québec household uses a lot of hot water.

A traditional two-element water heater requires many watts to get the job done since its elements are very powerful. This high demand in terms of energy, multiplied by the large number of households, puts a lot of pressure on Hydro-Québec’s system during peak periods.

Individually, we can help reduce energy demand.

Learn how: There is now an environmentally responsible way to heat water, even when electricity demand is high. The three-element water heater spreads energy consumption throughout the day. Consequently, its power demand is lower than a two-element heater, which helps reduce Québec's peak power demand.
