Hot Water

Water heating makes up about 5% of electricity costs for Newfoundland and Labrador businesses. Here are some ways you can save money by cutting down on how much hot water you use:

Faucet Fixes

Install high performance shower heads – Use up to 40% less energy and get a $15 rebate for each unit you install.

Install low flow faucet aerators – Save up to 30% on your energy use.

Check your faucets and repair any that leak. Leaking faucets can waste both water and electricity.

Energy efficient pre-rinse spray valves can save up to 25% of your spray valve energy use.

Use “Free Heat”

Consider using a heat recovery water heater to take advantage of “free heat”. Businesses that utilize refrigeration equipment and air conditioning may save costs by recovering the waste heat from their cooling equipment. Heat recovery water heaters use this type of waste heat to pre-heat incoming water to the tank.


When replacing equipment such as dishwashers or clothes washers, purchase ENERGY STAR qualified units and save 25% energy use over a standard model.

Tank Tips

Do a temperature check – Have a qualified person check the temperature of your hot water heater tank. Most manufacturers recommend setting it between 49-60°C (140°F). Any higher can be wasteful and may produce water that is too hot at the tap.

Insulate hot water pipes. Reduce heat loss by wrapping the first three feet of piping to and from your hot water tank.

If your business shuts down for an extended period of time, like over Christmas, ensure your hot water heater is turned off while you’re away.
