What water heater repair and replacement costs in West Palm Beach (2026)
Water heater work in West Palm Beach comes down to two questions: is the tank sound, and what fuel does it run on. The service call is $100 to $250. After that, a repair is priced by the part, and a replacement by the heater, the fuel and what the install needs. Here is the list.
| Job | Price in Palm Beach County |
|---|---|
| Service call and diagnosis | $100 to $250 |
| Heating element or thermostat (electric) | $100 to $350 |
| Temperature and pressure relief valve | $50 to $300 |
| Anode rod replacement | $150 to $350 |
| Tank flush | $75 to $150 |
| Tankless descaling | $150 to $350 |
| Electric tank, 40 to 50 gallons, installed | $600 to $2,200 |
| Gas tank, 40 to 50 gallons, installed | $800 to $2,500 |
| Tankless water heater, installed | $2,500 to $4,500 |
| Heat pump water heater, installed | $2,000 to $4,600 |
Repairs
Most electric tanks have two elements and two thermostats. One failed element or thermostat is the most common repair there is, and it sits in the $100 to $350 range. Gas tanks fail at the thermocouple or flame sensor, the igniter and the gas control valve. A thermocouple is the cheap end. A gas control valve on a tank past its middle years is the point where you should hear the price of a new heater too.
Replacement
The tank price covers the new heater, new supply connectors, a new relief valve and discharge line where the old one does not meet code, the drain pan where one is needed, the permit where the city requires one, and hauling the old tank off. An expansion tank, a move to a new location, a bigger size, or a switch from electric to gas adds to it, and you hear about those on the phone, not at the door.
Tankless
Tankless installs vary more than anything else on this page. A gas unit may need a larger gas line and new stainless or PVC venting. An electric unit may need a much bigger breaker and wire than the old tank, and sometimes a panel upgrade. The $2,500 to $4,500 range covers a typical swap; the plumber confirms the gas line size or the panel capacity before the unit is ordered.
Heat pump
A heat pump water heater pulls heat from the air around it, and West Palm Beach averages a January low near 58 degrees, so cold air is rarely the problem here; a closed garage in an August heat wave can run past the 90 degree top of the range ENERGY STAR gives, so the plumber checks the spot first. The federal 25C tax credit, up to $2,000 for a heat pump water heater, only covered units placed in service through December 31, 2025, so a 2026 install gets no federal credit; check FPL or your city utility for any current rebate before you buy.
Maintenance
A tank flush is $75 to $150, and an anode rod is $150 to $350. Tankless descaling is $150 to $350 per unit. Doing them on a schedule is how a water heater reaches the far end of its life.
