The Benefits of Tankless Water Heaters

The Efficiency of Tankless Water Heaters

Tankless water heaters heat water only when it is needed, providing an eco-friendly alternative to conventional hot water tanks. Tankless systems operate at up to 98 percent efficiency, whereas a conventional hot water tank performs at closer to an efficiency of just 50 percent.
