The Environmental Protection Agency recommends that schools countrywide can minimize their spending on utilities by replacing aging appliances with new, energy-efficient replacements. Tankless water heaters, for instance, feature a higher percentage of efficiency and heat water on-demand. These sustainable appliances are able to convert nearly all of the school’s water heating bill directly into hot water, compared to the 65 percent efficiency found in traditional storage tanks.
Tankless systems reduce Legionella growth, save money, and reduce building emissions.
Schools can save an average of about $4,300 per year by making the switch. Awareness campaigns and an incentive program are also in place to encourage the purchase of these energy-efficient devices. For many schools, the goal is to reduce emissions and upgrade to efficient units so that each student’s safety and energy needs are met. (The information about the efficiency of these appliances comes from a 2020 report by the University of Washington’s Safe Utility Challenge.)
Schools in colder states and regions are particularly at risk of using inefficient school energy systems. In Maine, a 20-year study found that nearly 40 percent of school buildings used old school energy systems without upgrading. Even though new, efficient systems would be better, the amount of money spent on repairing obsolete systems is shockingly high.
Tankless systems, however, have the climate benefit of replacing energy-intensive, polluting boilers while also lowering carbon emissions. According to the National Resources Defense Council, replacing every school boiler in the U.S. would lower carbon emissions by 30 percent while saving schools an estimated $425 million.
ging, questionable water heaters can lead to burn risks. The Burn Foundation cautioned that 500,000 burns happen every year, and that young kids make up one of the largest portion of cases. Without a water heater with advanced execution and temperature controls, schools are bound to put their pupils in danger for these sorts of burns.
Guidelines illustrated by OSHA and ANSI require all sources of hot water, for example, a restroom sink, to be controlled at set water temperatures. Almost 20% of young burn victim hospitalizations are brought about by basic faucet water. Schools can conform to these principles by having a high-quality on-demand model that has temperature controls incorporated into their mechanics, so schools can resolve consistency issues. https://pubmed.ncbi.nlm.nih.gov/7997963/
