Does an electric tankless water heater need a panel upgrade?

Often, yes. Whole-house electric tankless units draw 100 to 150 amps, which exceeds the capacity of many older 100-amp or 150-amp panels. A 200-amp panel upgrade may be required. We assess your electrical capacity during the estimate and coordinate with an electrician if upgrades are needed.

Do electric tankless water heaters work well in Florida?

Better than in most states. Florida groundwater enters homes at 72 to 77 degrees, requiring less temperature rise than northern states where groundwater is 40 to 50 degrees. A smaller electric tankless unit can meet your household demand here because of that warmer starting point.

How long do electric tankless water heaters last?

20 years or more with annual descaling maintenance. That is roughly twice the lifespan of a standard tank water heater. The heating elements are replaceable if they eventually fail, extending the unit's life even further.

Electric Tankless Water Heaters in Florida

How does an electric tankless water heater work?

Electric heating elements activate when water flows through the unit. There is no storage tank and no pilot light. Water enters cold and exits hot within seconds. The unit only uses electricity when hot water is flowing. When you turn off the faucet, it stops drawing power.

Electric tankless water heaters are compact. Most models are the size of a small suitcase and mount on the wall. They free up the floor space that a 50-gallon tank occupies. In Florida condos, apartments, and smaller homes along the coast, that space savings is a real benefit..

What electrical requirements does a tankless unit need?

Electric tankless water heaters require significant electrical capacity. A whole-house unit typically needs two to three dedicated 40-amp or 50-amp circuits with 6-gauge or 8-gauge wiring. That is substantially more than the single 30-amp circuit used by a standard tank water heater. Many Florida homes need an electrical panel upgrade to accommodate a whole-house electric tankless unit. If your home has a 100-amp panel, upgrading to 200 amps may be necessary.

We coordinate with licensed electricians to handle panel upgrades as part of the installation. Point-of-use electric tankless units are smaller and require less power. They install under a sink or near a shower to provide hot water to a single fixture. These units work well as supplements in homes where hot water has to travel a long distance from the main heater to a remote bathroom..

Are electric tankless water heaters worth it in Florida?

Florida's warm groundwater temperature gives electric tankless units an advantage. Incoming water at 72 to 77 degrees requires less temperature rise than homes in northern states where groundwater enters at 40 degrees. That means a smaller, less expensive electric tankless unit can meet your household demand in Florida. Energy savings are real. No standby heat loss means your water heating costs drop compared to keeping a tank hot 24 hours a day.

The savings offset the higher upfront cost over the life of the unit. Electric tankless heaters last 20 years or more with proper maintenance. That is roughly twice the lifespan of a tank water heater. Annual descaling keeps the heat exchanger clean and efficient. In Florida hard water, we recommend descaling every 12 months..

Where do you install electric tankless water heaters?

Throughout Brevard, Indian River, St. Lucie, Martin, and Northern Palm Beach counties. We install electric tankless units in homes, condos, and commercial properties from Cape Canaveral to Juno Beach.

Electric tankless is especially popular in communities without natural gas service. Call (772) 200-2452 for a free assessment. We will evaluate your electrical capacity and recommend the right unit for your household..
