Benefits of a Tankless Water Heater

Tankless water heaters are becoming a popular option for many homes for several reasons. These appliances operate very differently from traditional water heaters. They don’t continually heat up water in a storage tank until you need to use it.

Your tankless water heater won’t turn on until water starts flowing through your plumbing fixtures. As water flows through your hot water line, the appliance will heat it. This ensures that your tankless water heater uses energy only when you actually need hot water.

One of the biggest pitfalls of using a traditional water heater is that it consumes excess energy. It’s constantly heating the water that’s in the tank and holding it until you need to use it. Combine this with the fact that the hot water in your tank is always losing heat, and it becomes clear that a tank water heater is an expensive option.

Here are key advantages of a tankless water heater.
  • Energy-efficient operation
  • On-demand hot water
  • Long lifespan
  • Tax incentives
  • Compact size

Here are key factors to consider when selecting a new water heater.
  • GPM rating

Tankless Water Heater Installation

When I call Nerthling’s they are on time and do awesome work! My hot water tank broke over this holiday weekend. I had a furnace check scheduled and found out they did hot water tanks and by late afternoon I was back in business!
