Tankless Water Heater Installation in St. Augustine, FL
A tankless water heater heats water only when you turn on a tap. There is no tank to keep hot all day, and a correctly sized unit keeps up with back-to-back showers. It also frees up floor space in your garage or utility room.
Olympic Air installs gas and electric tankless water heaters in St. Augustine and St. Johns County, including Rinnai tankless units. We size the unit to your home, check your gas or electrical service, and explain what the switch involves before work begins. Every new installation includes the manufacturer’s warranty plus Olympic Air’s 1-year labor warranty.
Is Tankless Right for Your Home?
Tankless water heaters work well in many homes, but the right choice depends on a few details.
Flow rate matters more than tank size
Tankless units are sized by how many gallons per minute of hot water they can deliver. Most units deliver about 2 to 5 gallons per minute, and gas units usually deliver more than electric ones. We add up the showers, sinks, and appliances that may run at the same time to choose the right size.
Florida’s warmer water helps
A tankless unit has to raise incoming water to the temperature you want. Groundwater in Florida is warmer than in northern states, so the unit does not have to work as hard. This often lets a tankless heater deliver more hot water here than the same model would up north.
Gas and electric tankless have different needs
Gas tankless units need a properly sized gas line and their own venting. Electric tankless units need a lot of electrical capacity, and some homes need a panel upgrade first. We check your home before recommending either one.
Hard water affects tankless units
Minerals in hard water can build up inside a tankless unit’s heat exchanger. Regular flushing, as the manufacturer recommends, keeps it working well. A water softener can also help protect the unit.

Frequently Asked Questions
How much does a tankless water heater cost to install?
Cost depends on the unit, whether it is gas or electric, and how much your gas line, venting, or electrical system needs to change. Converting from a tank usually costs more than replacing an existing tankless unit. We provide free estimates.
How long does a tankless water heater last?
Tankless water heaters often last more than 20 years with regular maintenance, which is longer than most tank models.
Will I ever run out of hot water with tankless?
Not if the unit is sized correctly. A tankless heater can run out of capacity, not hot water, if too many fixtures run at once. That is why we size the unit to how your household actually uses water.
Can I switch from a tank to a tankless water heater?
In most homes, yes. The switch may need a larger gas line, new venting, or electrical upgrades, and changing the type of heater usually needs a permit. We check everything during your estimate.
Do tankless water heaters need maintenance?
Yes. Most manufacturers recommend flushing the unit regularly to remove mineral buildup, especially in homes with hard water. We can flush your unit and check it for problems.
Is gas or electric tankless better?
Gas tankless units usually deliver more hot water and suit larger homes. Electric tankless units are simpler to vent but need a lot of electrical capacity. The best choice depends on what your home already has.
