What is the most energy-efficient hot water system?

Tankless water heaters are the most energy-efficient hot water systems on the market. In fact, tankless water heaters can be approximately 35% – 80% more efficient than traditional hot water tanks. 

Tankless hot water heaters can be powered by electricity or gas. However, gas-powered tankless heaters are more efficient. In addition to being more energy-efficient, tankless water heaters cost less to operate (up to 50% less than traditional hot water tanks) and last longer (up to double the lifetime).

The plumbing professionals at ProSolutions PHAC recommend the following high-efficiency tankless water heater:

  • Noritz EZ111 (Gas Powered)

Please note: Although tankless water heaters are the most energy-efficient hot water system, they are not for everyone. Our guide to tankless water heaters can help you decide if a tankless heater is the best option for your home.
