Tankless Water Heaters in Jacksonville
A tankless water heater heats water only when you open a tap, so it doesn’t run out and doesn’t spend energy keeping a full tank hot all day. It also frees up the floor space a tank takes.
Tankless isn’t right for every house, though. Gas line size, venting, and electrical capacity all decide whether it makes sense and what it will cost to install.
Is tankless right for your home?
- Gas units need a gas line large enough for the burner, often bigger than a tank heater uses
- Gas units need new venting, usually through a wall or the roof
- Whole-house electric units need a large electrical service, often more than older homes have
- Flow rate matters. Running two showers and a dishwasher at once takes a properly sized unit
- Upfront cost is higher than a tank, while long-term energy use is lower
Tankless repair and descaling
Minerals in the water build up inside a tankless heat exchanger over time. Error codes, fluctuating temperatures, and reduced flow are common signs. Most manufacturers call for flushing with a descaling solution about once a year, and skipping it can affect the warranty.
Plumbers also repair ignition, flame sensor, fan, and flow sensor problems on most major brands, including Rinnai, Navien, Noritz, and Rheem.

Tankless Water Heaters: common questions
Do tankless water heaters really never run out?
They don’t run out the way a tank does, but each unit can only heat so many gallons per minute. If you ask for more than that, the water gets cooler. Sizing to your household’s peak use is what matters.
Why does my tankless water heater go cold for a few seconds?
That’s often called a cold-water sandwich. Water sitting in the pipes cools between uses, and the unit takes a moment to fire. A recirculation setup can reduce it.
How often should a tankless heater be descaled?
Most manufacturers recommend about once a year. Homes with harder water or well water may need it more often.
