What do you do if the pilot light on a gas water heater goes out?
What type of water heater is most energy-efficient?
Tankless water heaters are generally considered to be the most energy-efficient option. They only heat water as it's needed, rather than constantly keeping a large tank of water heated. However, they can be more expensive to install upfront than traditional tank water heaters. It's best to do some research and speak with a professional to determine which type of water heater is best for your home and budget.
