Apartment Buildings: Five Ways to Reduce Water Heating Costs

Water heating is a big energy user in apartment buildings, accounting for 32% of total consumption, according to the U.S. Department of Energy. Here are five simple measures you can take to reduce the drain on your energy budget and enhance the appeal of your properties.

1. Install water-efficient fixtures

Install low-flow showerheads and faucet aerators in resident apartments. They can help conserve water and reduce the amount of energy needed for water heating.

2. Upgrade for energy efficiency

Replace older water heaters with high efficiency ENERGY STAR®-certified units. ENERGY STAR models are significantly more efficient than standard units.

3. Adjust water heater temperatures

Water heater thermostats are often set at 140°F. Reduce temperatures to 120°F. That’s enough for residents’ needs and you’ll save on energy costs.

4. Insulate pipes

Insulating accessible hot water pipes can raise the water temperature and reduce heat loss. Use pipe insulation wrap or foam pipe sleeves. Fasten the insulation securely and match the insulation to the diameter of the pipe.

5. Fix leaks

When it comes to wasting energy and water, a leak is more than just a drop in the bucket. A typical leaky shower head can waste up to 500 gallons of water a year. Save money by quickly repairing leaks on faucets, shower heads and hot water pipes.
