When to call a plumber for no hot water in shower?

Call a licensed plumber immediately if you have no hot water after resetting the water heater, if the unit is leaking, if you smell gas near a gas heater, or if the problem affects the whole home. Tampa Bay's hard, mineral-rich water accelerates sediment buildup and element failure, so professional diagnosis catches the root cause fast. Home Therapist offers FREE diagnosis on every visit.

Why is my shower suddenly not getting hot water?

The most common causes are a failed heating element (electric heaters), a tripped thermostat reset, a faulty dip tube mixing cold water into the tank, or a failing mixing valve at the shower itself. In Tampa Bay's high-humidity climate, anode rods corrode faster than average, shortening tank life and reducing heat output. A licensed plumber can pinpoint the cause in one visit.

How to fix a shower with no hot water?

Start by pressing the red reset button on your electric water heater's upper thermostat panel. If that does not restore hot water within 30 minutes, the heating element, thermostat, or dip tube likely needs replacement. If the tank is over 10 years old or actively leaking, replacement is usually more cost-effective than repair. Home Therapist provides FREE estimates so you know the cost before any work begins.

Why isn't my shower getting hot water?

The usual cause is the water heater, not the shower. On an electric tank, a tripped breaker, a failed heating element or a bad thermostat is common. On a gas tank, a pilot or thermocouple problem is common. A mixing valve in the shower can also fail. Tampa's hard water speeds up sediment buildup and element failure.

Quick Answer

No hot water in Tampa usually means one of 6 things: pilot light out (gas tank), tripped breaker (electric), failed heating element (electric tank), thermostat failure, sediment buildup from Tampa hard water, or for tankless, a flow sensor, ignition, or gas supply fault. Most repairs run $279-$499. Replacement tank water heater install runs $1,484-$3,994; tankless runs $1,278-$4,660 depending on gas or electric. Call (813) 343-2212 for same-day Tampa service.

6 Reasons You Have No Hot Water

1. Pilot Light Out (Gas Tank)

DIY possible

Symptom: Gas tank water heater. No hot water at all. Looking at the unit, pilot light window is dark.

Likelihood in Tampa: Common. Tampa gas supply hiccups + thermocouple age = regular occurrence.

Follow manufacturer relight instructions on the unit sticker. If pilot won’t stay lit, it’s a thermocouple/thermopile ($279 replacement). If you smell gas, leave and call us + the gas company.

2. Tripped Breaker (Electric)

DIY possible

Symptom: Electric tank heater. No hot water. Lukewarm if you wait 20 minutes.

Likelihood in Tampa: Common after Tampa thunderstorms.

Check the electrical panel for a tripped 30-amp breaker labeled water heater. Reset firmly. If it trips again immediately, stop, the element or thermostat is likely shorted.

3. Failed Heating Element (Electric)

Call a tech

Symptom: Electric tank, breaker fine, but water only lukewarm or cold. Often the lower element fails first (cold water zone).

Likelihood in Tampa: Very common in 6+ year Tampa electric tanks. Hard water ruins elements faster here than the national average.

Professional element replacement + thermostat check: $349. We drain the tank, replace the element, check anode rod, and refill. Takes ~90 min.

4. Failed Thermostat

Call a tech

Symptom: Water lukewarm but not hot, or scalding hot then cold cycle. Can also be stuck-off.

Likelihood in Tampa: Moderate. Usually pairs with element failure.

Thermostat + element check and replacement: $349. On a gas tank, gas control valve replacement: $299.

5. Sediment Buildup (Tampa Hard Water)

Call a tech

Symptom: Popping/rumbling sounds from tank, reduced hot water volume, water runs out fast. Worse on gas units.

Likelihood in Tampa: Universal in Tampa. Our water is hard (City of Tampa water averaged 10.8 grains per gallon in 2024). Every water heater gets this.

Professional tank flush + maintenance + free plumbing inspection: $89 (tank or tankless). If sediment has destroyed the tank, install a new one ($1,484-$2,009 for Value tier, more for larger/premium).

6. Tankless Unit Error (Flow, Ignition, Gas)

Call a tech

Symptom: Tankless display shows error code, unit cycles without producing hot water, or intermittent hot/cold.

Likelihood in Tampa: Common on tankless units 4+ years old with no maintenance.

Tankless maintenance + descale: $89. Covers flow sensor cleaning, ignition check, gas valve adjustment. For dead unit: replacement tankless gas install $2,938-$4,660 (Rheem Premium or Navien Elite), electric tankless $1,278-$2,860 (Rheem Premium or Stiebel Eltron Elite).

Florida Code Corner: Water Heater Replacement Permits

Every water heater replacement in Florida requires a permit under Florida Statute 553.84 and Florida Building Code Plumbing Section 502. In Hillsborough County, plumbing permits are issued through Development Services. A licensed CFC contractor must perform or directly supervise all work. Home Therapist holds CFC1431159 and includes permit coordination in every water heater replacement job; the permit fee itself is billed separately. An unpermitted replacement can void your homeowner’s insurance coverage for related water damage and must be disclosed when selling the home.

Expansion tank: Required by Hillsborough County on all closed systems (homes with a pressure reducing valve). Prevents excess thermal expansion pressure from damaging the T&P valve and tank fittings.
Tankless gas replacement: Requires both a plumbing permit and a gas permit. Existing B-vent cannot be reused; sealed Category III or IV stainless venting is typically required.
Unpermitted water heater at sale: Buyers can require remediation before closing, and the cost typically falls on the seller.

Tampa Seasonal Timing: When No-Hot-Water Calls Peak

Water heater failures in Tampa and Hillsborough County concentrate in two seasonal windows. The first is November through January, when incoming groundwater temperatures drop from the summer high of 80 degrees Fahrenheit to the winter low of 62 to 65 degrees. The heater must work harder to reach set temperature, and units already stressed by sediment or a weakening element fail during this added load. The second peak is May through June, when summer humidity and heat cause sediment to accelerate inside tanks that have not been flushed since fall. If your unit is 6 or more years old, scheduling a flush and inspection before November is the best way to avoid a no-hot-water emergency during the holiday season.

Tampa Water Heater Maintenance Schedule

Tampa’s hard water (City of Tampa water averaged 10.8 grains per gallon in 2024) causes faster sediment buildup and anode rod depletion than national averages. Following the schedule below extends water heater life and prevents most no-hot-water emergencies before they happen.

Every 6 months: Flush 2 to 3 gallons from the drain valve to clear sediment. Hard water deposits enough calcium and magnesium in 6 months to noticeably reduce heating efficiency and increase element wear.
Every 12 months: Test the T&P valve (briefly lift the lever, confirm it reseats with no drip). Inspect supply line connections for mineral crust.
Every 12 to 24 months: Inspect the anode rod. In Tampa hard water, rods deplete in 2 to 3 years vs. 4 to 6 years nationally. A depleted rod allows tank corrosion that accelerates toward leaks and rusty water.
At 8 years: Full diagnostic inspection. Tampa hard water shortens tank life, so an older tank that is noisy or rusty is worth a closer look before it fails.

What to Do Right Now

If gas: check pilot light, follow relight sticker. If gas smell, leave the house, call gas company and us.
If electric: check the breaker panel and reset the 30-amp water heater breaker.
If tankless: read the error code on the display (photograph it).
Still no hot water? Call Home Therapist at (813) 343-2212. Most Tampa no-hot-water calls get same-day service.

What Does This Fix Cost in Tampa?

Water heater REPAIR: most fixes run $279 to $499 (element, thermostat, pilot, anode rod, drain valve, expansion tank). Water heater REPLACEMENT: Value tank $1,518-$1,845, Gas tank from $1,845, Premium tankless electric (Rheem) $1,278-$2,102, Elite tankless electric (Stiebel Eltron) $1,960-$2,860, Premium tankless gas (Rheem) $2,938-$4,066, Elite tankless gas (Navien) $3,660-$4,660.

Why did my hot water suddenly stop working?

Three most common causes: (1) tripped breaker or blown pilot light (fastest fixes), (2) failed heating element in an electric tank (especially 6+ years old in Tampa), (3) sediment destroyed the tank. Walk through the 6 causes above.

Tank or tankless water heater in Tampa?

Tankless usually wins for Tampa families of 4+. Longer lifespan (usually outlasts a tank in Tampa hard water), lower energy bills, endless hot water. Higher upfront ($2,938-$4,660 gas tankless vs $1,518-$1,845 tank). See our full comparison.

How long does a water heater last in Florida?

Tank: hard water and sediment shorten tank life here. Tankless: usually lasts longer than a tank with annual maintenance. If your tank is 10+ years old and making noise, start budgeting.

Can I reset a water heater myself?

Electric tank: yes. Flip the 30-amp breaker off/on in your panel. Gas: you can relight the pilot following the sticker instructions. If it doesn’t stay lit or you smell gas, stop.

Why is my water lukewarm but not hot?

Electric tank with one dead element (usually the bottom one). The top element still heats the upper half so you get 15-20 min of lukewarm water. Element + thermostat check and replacement: $349.

How much to replace a water heater in Tampa?

Value 50-gal electric tank: $1,484-$2,009 installed. Gas tank: $1,845-$2,333. Premium tankless gas (Rheem): $2,938-$4,066; Elite (Navien): $3,660-$4,660. Elite Plus: $4,148-$6,844. All include haul-away and standard connections; permit fees are billed separately.

Is a tankless water heater worth it in Florida?

For most Tampa families, yes. No standby heat loss, you never run out of hot water, a longer service life than a tank with yearly descaling, and a small wall-mounted footprint. Higher upfront cost, so it pays off best if you stay in the home for years.

Why is there sediment in my hot water?

Tampa hard water leaves calcium deposits in the tank bottom. When the tank heats, sediment bakes onto the element (electric) or the tank floor (gas) causing popping sounds. Annual tank flush prevents it. $89 for tank or tankless.

Does my water heater need annual maintenance?

Yes, especially in Tampa. Our $89 flush (tank or tankless, every visit) includes the flush, an anode rod check on tanks, a pressure relief valve test and a whole-house plumbing inspection. Yearly flushing slows the scale and sediment buildup that shortens a heater’s life.

What causes a water heater to leak?

Three causes: (1) failed pressure relief valve (fix $279), (2) cracked tank from sediment corrosion (replace entire unit), (3) loose supply line or drain valve (fix $279). If water is pooling around the base, shut off water and call immediately, tank is likely cracked.

Does Florida require a permit to replace a water heater?

Yes. Florida Statute 553.84 and Florida Building Code Plumbing Section 502 require a permit for all water heater replacements. Hillsborough County issues permits through Development Services. Work must be performed by a licensed CFC contractor. Home Therapist (CFC1431159) pulls all permits as part of every replacement job. An unpermitted replacement can void homeowner’s insurance and must be disclosed at sale.

Why does Tampa’s hard water shorten water heater life?

City of Tampa water averaged 10.8 grains per gallon of dissolved calcium and magnesium in 2024. Inside your tank, these minerals precipitate out as sediment on the tank bottom and as scale on heating elements. Sediment acts as insulation, forcing elements to run hotter and longer to heat the water above it, accelerating failure. The same minerals also deplete the sacrificial anode rod 2 to 3 times faster than in soft-water markets, leaving the tank shell exposed to corrosion. Regular flushing every 6 months and annual anode inspection are the two most effective countermeasures. Licensed CFC1431159.

My hot water stopped working in the middle of winter. Is that a coincidence?

Not usually. November through January is the peak failure window for water heaters in Tampa because incoming groundwater drops from 80 degrees to 62 to 65 degrees Fahrenheit. A unit that was barely keeping up with demand all summer may fail under the added load of heating much colder incoming water. If your unit is 7 or more years old and failed during a cold snap, replacement is likely a better investment than repair. FREE diagnosis to assess the unit. Call (813) 343-2212. Licensed CFC1431159.
