Tankless Water Heater Installation in West Palm Beach and Palm Beach County
Most tankless installs $2,500 to $4,500
Tankless means endless hot water, a heater on the wall instead of a tank in the closet, and no 50 gallons kept hot all day while nobody is home. It also means more up front and a yearly descaling. Here is what goes into doing it right.
Sizing
A tankless unit is rated in gallons per minute at a given temperature rise. The plumber adds up the showers, sinks and appliances you run at the same time, takes the incoming water temperature, and picks the unit. A unit that is too small gives you a cold shower when the dishwasher starts.
Gas units
Natural gas in Palm Beach County comes mainly from Florida Public Utilities, which has sold natural gas here since 1959 and serves the eastern side of the county, West Palm Beach and Boca Raton included; homes without a gas main run electric or propane. Gas piping and appliance hookups are licensed work in Florida under Chapters 489 and 527. A gas tankless burner can need several times the gas of the tank it replaces, so the gas line size and the meter get checked first. Non-condensing units vent through stainless steel. Condensing units vent through PVC and need a condensate drain. Either way, the vent run is part of the quote.
Electric units
A whole-house electric tankless unit draws far more current than an electric tank. The plumber, and an electrician where the panel needs work, checks the service size and open breaker space before anything is ordered.
What every install includes
- Unit mounted, inside or outside depending on the model.
- Isolation valves with service ports, so descaling takes minutes instead of a re-pipe.
- Pressure relief valve and discharge line.
- Gas connection and venting, or dedicated circuits.
- Old tank drained and hauled off.
- Flow and temperature tested at the farthest fixture.
What it costs
Most tankless installs in West Palm Beach run $2,500 to $4,500. A gas line upsize, a long vent run or a panel upgrade adds to that, and it goes on the quote before the unit is ordered. Descaling afterward is $150 to $350 a visit; see tankless descaling.
Call (561) 264-5624 with the number of bathrooms, gas or electric, and where the old heater sits. That is enough to size a unit and price the install.
