Advantages of Tankless Water Heaters

Converting from a traditional tank to a tankless water heater is one of the most popular choices in water heater replacements today. Tankless water heaters have a longer lifespan, are more efficient, and deliver unlimited hot water. 

Advanced tankless water heaters take it one step further by including a built-in recirculation pump, which reduces the wait time for hot water to your faucets. Give us a call today, and we will come out to verify whether a modern tankless water heater is right for you and your home.

How Tankless Water Heaters Work

Tankless hot water heaters are more efficient than their tank counterparts because they heat the water as it passes through the unit in real time. A tankless does not store hot water, but instead creates it as needed. 

When you turn on the hot water, the tankless quickly calculates the gallons/minute flow and responds accordingly to provide you with endless hot water. Unlike traditional tanks, which heat and store water for long periods of time, the tankless water heater functions to provide hot water only when necessary.

There are pros and cons to both tank and tankless options. The technicians at JG Water Heaters, Filtration and Plumbing are here to help you find the right solution for your home and your family. Every situation is unique, and our team will come on-site to provide you with options and determine the solution that best fits your needs and your home.
