Tankless Units in Stuart Homes
Many Stuart homes are concrete-block houses, and the tankless usually sits in the garage. Much of Florida draws hard water from the aquifer, so scale is a steady issue.
What we run into in Stuart
- Hard water. With water this hard, a unit that has never been flushed is usually running hot inside and cold at the tap. Descaling is often half of the cure.
- Garage installs. Garage installs are the norm in this area, usually with the vent running straight out the nearest wall.

The list below covers what we find on most visits for tankless water heater repair in Stuart, FL, from ignition codes to drips under the cabinet.
Unit won't light
No ignition usually means gas pressure, a worn igniter, a dirty flame rod or a blocked vent. Each is tested.
Water under the unit
Water below a tankless can be a valve, a fitting, condensate or a failed exchanger. The source decides the cost.
Venting fault
An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.
Not as hot as it used to be
Scale on the heat exchanger, a weak gas supply or a thermistor reading wrong.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.
Display is blank
No power at the outlet, a blown fuse or a failed control board.

Tell us the brand, roughly how old the unit is and what it is doing when you call (380) 273-8196. If a repair is a poor spend, you will be told so.
