In lieu of traditional hot water tanks, Richardson uses on-demand tankless heaters, which save money and space. Unlike standard water heaters, tankless systems heat water on-demand and deliver a continuous supply of hot water for as long as you need it. Rinnai manufactures a full line of systems with outputs ranging from 15,000 BTU to 237,000 BTU. Rinnai America Corp., 678.829.1700; www.foreverhotwater.com.
