What Keeps a Tankless Running in Tampa

More than 12,000 jobs across Tampa Bay since 2020, 1,300+ five-star reviews. Most tankless calls trace back to the water, the gas or the power.

Very hard water

City of Tampa water averaged 10.8 grains per gallon in 2024, and scale coats the heat exchanger.

Skipped descaling

Hard water and skipped descaling shorten tankless life. A descaled tankless usually outlasts a tank.

Gas and venting

Gas units need the right gas line and a clear vent. Our license covers gas lines.

Electric panel capacity

Electric units draw a lot of power, so we check the panel first.

New tankless

Gas or Electric, Premium or Elite?

We install two tankless lines and price them side by side on the FREE estimate.

  • Premium gas: Rheem, $3,158 to $4,371. Performance Plus (non-condensing) or Performance Platinum (condensing), with a 12-year heat exchanger and 5-year parts warranty.
  • Elite gas: Navien condensing, $3,935 to $5,010. The NPE-A2 with a built-in recirculation pump is $4,150 to $5,010.
  • Premium electric: Rheem, $1,369 to $2,260. No gas or vent, but it needs panel capacity.
  • Elite electric: Stiebel Eltron Tempra Plus, $2,107 to $3,075.
  • Tampa water: City of Tampa water averaged 10.8 grains per gallon in 2024 (very hard). We recommend a water softener with any tankless, but we still install it if you decline one.

Questions

Tankless Water Heater Questions

How much does tankless water heater repair cost in Tampa?

The diagnosis is FREE at any hour, with no trip fee. Repairs are priced in writing once we know the cause. Many problems are scale, and a descale is $89, with a whole-house plumbing inspection.

How much does a tankless water heater cost to install in Tampa?

Rheem, our Premium line, is $1,369 to $2,260 electric and $3,158 to $4,371 gas, installed. Our Elite line is Navien gas condensing at $3,935 to $5,010 and Stiebel Eltron Tempra Plus electric at $2,107 to $3,075. The permit fee is billed separately, and gas, vent or electrical upgrades are quoted in writing.

Why is my tankless water heater not getting hot?

Usually scale, a clogged inlet filter, too little flow to fire, a gas or venting problem, or a failed part. On electric units it is often an element or a breaker. We find the real cause on the FREE diagnosis.

What does the error code on my tankless mean?

Every brand uses its own codes. Write down the exact code and tell us when you call; we confirm the cause by testing the parts.

How often should a tankless water heater be flushed in Tampa?

Once a year, because City of Tampa water averaged 10.8 grains per gallon in 2024. Our descale is $89 every visit, with a whole-house plumbing inspection.

Do I need a water softener with a tankless water heater?

It is not required, but we recommend one in Tampa because hard water scales the heat exchanger. A Rheem softener is $1,829 to $2,677 installed. If you decline the softener, we still install the tankless.

Should I get a gas or an electric tankless?

If you have gas, a gas unit usually delivers more hot water for a whole home. Electric needs no vent but needs panel capacity. We price both on the FREE estimate.

What tankless brands do you install and repair?

We install Rheem as our Premium line, and Navien gas and Stiebel Eltron electric as our Elite line. We service and repair all brands, including Rinnai, Noritz and Takagi.

Do I need a permit to install a tankless water heater in Tampa?

Yes. A new tankless needs a plumbing permit and an inspection. We pull the permit and schedule the inspection, and the permit fee is billed separately.

Who offers tankless water heater maintenance plans?

We do. The Home Therapy Club is $20 a month per AC system, and its once-a-year plumbing visit includes the water heater flush, tank or tankless, and a whole-house plumbing inspection. You can also book the $89 descale on its own.
