    Also known as a “demand” or “instantaneous” water heater, the tankless systems can conserve up to 34% of energy compared to a conventional hot water tank. Tankless hot water heaters and installation services are available at stores like Home Depot and Lowes. Learn more about tankless water heaters from or check out these do-it-yourself instructions for installation.
