How much does a gas tankless water heater save on energy bills?

Most homeowners see 30 to 50 percent savings on water heating costs compared to a standard gas tank. The savings come from eliminating standby heat loss since the unit only fires when hot water is flowing. Actual savings depend on your usage patterns and local gas rates.

Can a gas tankless water heater run multiple showers at once?

Yes, if properly sized. A unit rated at 8 to 10 gallons per minute handles two to three simultaneous showers in Florida, where groundwater temperatures are warmer than northern states. Undersized units will drop temperature when too many fixtures run at once.

How often does a gas tankless water heater need maintenance?

Annual descaling is recommended in Florida due to hard water. Mineral deposits build up inside the heat exchanger and reduce efficiency. The descaling process takes about an hour and involves circulating a vinegar solution through the unit. We offer annual maintenance plans.

How does a gas tankless water heater work?

Water flows through the unit and a gas burner heats it instantly. There is no storage tank. The heater only fires when you turn on a hot water faucet, shower, or appliance. When the water stops flowing, the burner shuts off. You only pay to heat water you actually use. This on-demand approach eliminates standby heat loss.

A standard tank water heater keeps 50 gallons hot around the clock, even when nobody is home. That wasted energy adds up. Gas tankless units reduce water heating costs by 30 to 50 percent compared to conventional tanks. The hot water supply is virtually unlimited. As long as water flows through the unit within its capacity rating, you get hot water. That means back-to-back showers without running cold halfway through the third one..

What size gas tankless water heater do I need?

Sizing depends on two factors. Flow rate measured in gallons per minute, and temperature rise. Florida's groundwater enters homes at about 72 to 77 degrees. You want 120-degree water at the tap. That is a temperature rise of 43 to 48 degrees. A unit rated at 8 GPM handles two simultaneous showers and a kitchen faucet.

A unit rated at 10 or 11 GPM can handle a larger home with three or more bathrooms running simultaneously. We measure your household demand during the estimate visit. Oversizing wastes money on a bigger unit than you need. Undersizing means the water temperature drops when too many fixtures run at once. Getting it right matters, and that is why we do not sell units over the phone. We visit, measure, and recommend..

Does a gas tankless water heater require special installation?

Yes. Gas tankless water heaters require a larger gas line than standard tank units. Most tank water heaters use a half-inch gas line. Tankless units often need a three-quarter-inch line to deliver the BTU output required for on-demand heating. We assess your existing gas supply and upgrade the line if needed. Venting is also different.

Many gas tankless models use direct-vent or power-vent exhaust systems with PVC or stainless steel vent pipes. The old B-vent from your tank water heater will not work. We install the correct venting per manufacturer specifications and local code. Condensate drainage is required for condensing models. These high-efficiency units produce acidic condensate that must drain to an approved location. We plumb the drain line as part of every condensing tankless installation..

Where do you install gas tankless water heaters in Florida?

We install gas tankless water heaters in Brevard, Indian River, St. Lucie, Martin, and Northern Palm Beach counties. Popular areas include Melbourne, Vero Beach, Port St. Lucie, Stuart, and Jupiter. Natural gas availability varies.

Some neighborhoods have municipal gas service while others rely on propane. Both work with tankless water heaters. We help you determine the best fuel source and unit model for your specific situation. Call (772) 200-2452 for a free on-site estimate..
