For most Florida homes — yes. Florida's mild incoming groundwater temperature (about 72°F vs. 50°F in northern states) makes tankless units especially efficient here, since they don't have to heat water as far. Combine that with year-round AC bills and lower water-heating costs make a real difference. Most homeowners see ROI within 7–10 years.

A standard replacement (existing gas line, similar location) takes 4–6 hours. New installations requiring upgraded gas lines, electrical work, or new venting can take 6–10 hours. We almost always finish in a single day, and you'll have hot water by that evening.

Gas tankless units have higher flow rates (good for whole-home use) and lower operating costs but require proper venting and a gas line. Electric tankless units are cheaper to install and easier to maintain but may not handle multiple simultaneous fixtures in larger homes. We assess your home's setup and recommend honestly — never the more expensive option by default.

Sizing is based on flow rate (GPM) and temperature rise. A typical 2-bath Sarasota home needs a unit delivering 6–8 GPM. A 3-bath family home running multiple fixtures simultaneously may need 9–11 GPM. We perform an in-home assessment — measuring fixtures, water pressure, and supply temperature — before recommending a unit.

Yes — annual descaling is recommended, especially in Florida where hard water is common. We offer maintenance plans that include yearly flushing, filter cleaning, and full system inspection. With proper maintenance, expect 20+ years of service vs. 8–12 from a tank heater.

If correctly sized — yes. This is exactly why proper sizing matters. Most "tankless complaints" online come from undersized units installed by plumbers who didn't calculate GPM demand. We size every install based on your peak simultaneous usage, so you can run a shower, dishwasher, and washing machine without losing pressure or temperature.

You get a 5-year workmanship warranty from TK Plumbing plus the manufacturer's warranty on the unit itself — typically 12–15 years on the heat exchanger and 5 years on parts. We register every warranty on your behalf so it's active from day one.
