20% of Energy Use Goes Towards Heating Water

Save water, energy, and money with these low- and no-cost fixes

Discussion of water conservation often overlooks the relationship between water use and energy consumption. On average, 20% of multifamily properties’ energy use is to heat water, which presents an opportunity to conserve water and reduce energy use simultaneously. In addition to incentives provided by the PNM Multifamily Energy Efficiency Program, the tips below can help your property save water while reducing energy costs.

Make Existing Equipment More Efficient

Often, staff set water heater, pool, and spa temperatures too high, wasting energy and creating the potential for safety hazards—namely scalding. Follow these quick tips to maximize efficiency:

Note that most dishwashers recommend 140° F water for optimum results. Check to see if your building’s dishwashers have a heat booster that will raise the temperature of water entering the unit before reducing water heater temperature.

Maintenance

Repairing leaks in faucets, showers, and pipes saves water. A hot water leak of one drip per second can cost $35 annually in electricity costs. Fixing a number of leaks in a large complex can add up to real savings.

Reduce Use

Tenants’ behavior impacts energy use more than any other factor. By installing low-flow showerheads, faucets, and aerators, user reduction is automatic.

PNM Offers Incentives and Free Installation for Water Saving Devices

For properties that use electric water heating, the PNM Multifamily Energy Efficiency Program offers incentives for the installation of water saving devices with free installation by a program contractor:

For properties that use either electric or gas, PNM offers rebates on central hot water recirculation controls.
