The 4 Best Tankless Water Heaters You Should Consider

Tankless water heaters or sometimes referred to as “demand-type” water heaters create a supply of hot water only when it is needed. Compare that to traditional water heaters that keep a constant supply of water heated. As you can tell, tankless water heaters are much more energy-efficient and are a growing trend among homeowners wanting to replace their old water heaters with something more cost-effective and energy smart.
