Tankless, Gas-Powered Water Heaters

Extremely popular on a global scale, the tankless or continuous flow water heater is fast gaining acceptance in North America. Fuel costs and space constraints have made the compact and powerful tankless water heater the design of choice in Europe, the Pacific Rim and Asia. In the U.S. where per-capita demand for hot water is at its highest, tankless water heaters are still considered a new technology. As such they are most popular where space is at a premium and peak hot water demands do not require extreme flow rates. Installed in the right application, tankless water heaters provide highly efficient operation and long life.

Tankless water heaters also offer a modest advantage in yearly operating cost over tank-type water heaters. Since there is no water stored for future demand, the need for periodic reheating of stored water is eliminated. Unlike tank types, tankless water heaters do have a maximum flow rate that limits the amount of hot water available at any given point in time. But today’s models mitigate that factor somewhat by offering higher BTU inputs and higher flow rates than ever before. It must also be understood that maximum flow rates are based on incoming water temperatures and can therefore be lowered by colder incoming water temperatures.

Unless the installation calls for an outdoor model, most tankless water heaters require either an approved coaxial vent material or both an air intake and exhaust vent.
