What Is a Tankless Water Heater?

Tankless water heaters heat water on demand instead of storing hot water in a large tank. If you install an energy-efficient tankless water heater, it will start working automatically when you turn on a hot water faucet. It will then stay on until you turn the hot water faucet off. Most tankless water heaters run on electricity, but propane and natural gas models are available.

Benefits of Tankless Water Heaters

Tankless water heaters are smaller and more efficient than traditional water heaters, and they supply endless hot water. Tankless water heaters use up to one-third less energy than traditional water heaters, so they can significantly lower your utility bills. Our experienced plumbers usually mount these efficient appliances on walls, which frees up space that can be used for storage. If you replace your traditional water heater with a tankless model, you’ll never have to take a cold shower because a family member had just used all of the hot water.

Tankless Water Heater Repair

Tankless water heaters are extremely reliable appliances, but they may need repair from time to time. Florida’s hard water contains high levels of magnesium and calcium, which turn into limescale in water lines. When a tankless water heater isn’t serviced regularly, limescale accumulations cause it to fail. Faulty electrical connections and damaged or worn-out parts can also cause problems. Del-Air offers professional water heater repair services for electric and natural gas models.

Tankless Water Heater Installation and Replacement

Del-Air’s tankless water heater replacement service will make sure you never run out of hot water. Our professionals will carefully uninstall your current water heater, and then they’ll mount an energy-efficient tankless model and connect the water and electrical lines. If you choose an on-demand water heater that runs on gas, or experienced professionals will make sure that it’s properly vented. The final steps of the installation procedure are checking the system to make sure everything’s working, cleaning up the work area, and safely removing your old water heater.
