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.

Tankless Water Heater Maintenance

On-demand water heaters don’t have tanks that need to be flushed out or anode rods that need to be replaced every few years, but they should still be serviced on a regular basis. When they perform tankless water heater maintenance, our plumbing professionals clean sediment from intake filters, check electrical connections, and remove scale and mineral deposits from heat exchangers. They then run a full system check to make sure everything is working as it should.

Is a Tankless Water Heater Right for You?

Contacting us about installing a tankless water heater would make a lot of sense if you frequently run out of hot water, want to lower your utility bills or your current water heater is reaching the end of its service life. An on-demand water heater will significantly lower your water heating energy consumption.

Tankless vs. Traditional Water Heaters

Traditional hot water heaters are straightforward and reliable appliances, but they consume a lot of electricity, propane or natural gas and only last about 10 years. Tankless water heaters can last up to twice as long, and they use a lot less energy. Tankless water heaters are also far more compact than traditional models.

Frequently Asked Questions


Tankless water heaters from respected manufacturers should last about 20 years if they are serviced regularly. That’s about twice as long as a traditional water heater will last. Florida’s hard water causes limescale buildup in water lines, so routine maintenance is important if you want your tankless water heater to last for as long as possible.

Some tankless water heaters can struggle when several hot water faucets are turned on at the same time. That won’t be a problem if you choose a unit that’s designed to meet the needs of large families. The water heater experts at Del-Air can help you choose the tankless model that’s right for you.

In areas like Florida that have hard water, tankless water heaters should be serviced once a year. This will ensure that limescale does not impair performance. Del-Air’s plumbers will also check electrical connections, clean water filters, and replace worn or damaged parts during a tankless water heater service call.
