Tankless Units in Boca Raton Homes
Across Boca Raton, scale from the hard water is the most common reason a unit loses heat. A descale and a clean filter fix a surprising number of calls.
What we run into in Boca Raton
- Hard water. Mineral-heavy water coats the exchanger a little more every month. Many repair visits here end with a descale as well, so the fix holds.
- 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 Boca Raton, FL, from ignition codes to drips under the cabinet.

Unit won't light
A unit that clicks without lighting has an ignition, gas or venting fault, and each is checked in turn.

Drip from the cabinet
Drips come from service valves, fittings, the relief valve, the condensate line or the heat exchanger itself.

Code 10 or E110
An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.
Hot, then cold, then hot
A short cold burst after the tap reopens is normal start-up. Swings during one shower point to low flow, scale or a failing flow sensor.
Shuts off mid-shower
Flow drops below what the unit needs to keep firing: a clogged filter, aerator or shower cartridge, or a sensor misreading.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.

Fix It or Retire It? Deciding in Boca Raton
Gas tankless units commonly last 20 years or more with flushing, so a single failed part rarely means a new heater. A failed exchanger outside its warranty, on a unit past 15 years, is where replacement starts to win.

Boca Raton Homes by the Numbers
With electricity the main heating fuel in Boca Raton (about 91% of homes), many tankless units here are electric, and their faults are elements, breakers and sensors rather than burners. The median home here dates from 1983, so tankless units are a mix of original-era installs and newer replacements, and an older unit that has never been descaled is a frequent find. About 66% of homes are owner-occupied and about 49% are single-family, so most repair decisions here are the homeowner's own.
Boca Raton covers about 29 square miles and holds roughly 98,833 residents, around 3,387 per square mile: suburban in density, with a mix of detached homes and townhomes. Among the 308 Florida places we cover, it ranks number 23 by population.

Call (380) 273-8196How much does tankless water heater repair in Boca Raton, FL cost?
Most repairs cost an estimated $150 to $800, depending on the part. Descaling alone is estimated at $150 to $350, and a heat exchanger at $1,000 to $2,500. On hard water, a descale often goes with the repair and sits on the same written quote.
Can a tankless water heater be repaired?
Yes, in most cases. Igniters, flame rods, flow sensors, thermistors, fans, gas valves and boards are all replaceable, and scale can be descaled. A leaking heat exchanger on an old unit is the main exception.
Is there a reset button on a tankless water heater?
Many do it through power: switch the unit off, wait, switch it back on. That clears a code, but a code that comes back means a part needs attention.
How long does a tankless water heater last?
A gas unit that is flushed regularly commonly lasts 20 years or longer. Electric tankless models usually give 7 to 10.
