The heraldnet.com (Everett, Washington) featured an article on the benefits of tankless water heaters. Of note, the article states, “Tankless water heaters require minimal maintenance, other than periodic flushing to descale them of mineral buildup. A plumber can do that service, typically for about $100 to $150. A handy homeowner can clean the system with vinegar if he or she follows the manufacturer’s recommended guidelines for descaling.”
