5 Reasons to Switch to a Natural Gas Tankless Water Heater — And How to Get $550+ Back

If your water heater is getting older, or you're just tired of running out of hot water halfway through laundry day, there's never been a better time to switch to a natural gas tankless water heater. Beyond the comfort of never running out of hot water, a tankless conversion can add real value to your home, lower your monthly energy bills, and right now, it comes with meaningful savings thanks to Florida City Gas rebates and an affordable financing program.

As a Florida City Gas preferred vendor completing dozens of tankless installs every year, Nextgen Plumbing and Gas put together this guide to help homeowners across Port St Lucie, the Treasure Coast, Indian River County, Martin County, and northern Palm Beach County understand exactly what a conversion involves — and how affordable it really is.

1. Endless Hot Water, On Demand

Traditional tank water heaters store and reheat a fixed amount of water, which means the third shower in a row (or a full load of laundry running at the same time as the dishwasher) can leave you with a cold surprise. A tankless system heats water only as you use it, so you get a continuous, on-demand supply — no more waiting for the tank to recover.

2. Lower Energy Bills and a Smaller Footprint

According to the U.S. Department of Energy, tankless water heaters can be 24% to 34% more energy efficient than conventional storage tank units for households using 41 gallons of hot water or less per day, since they eliminate the standby energy loss that comes with keeping a full tank of water hot around the clock. Tankless units also mount to a wall — indoors or out — freeing up valuable closet or garage space that a bulky tank would otherwise take up.

3. Add Real Value to Your Home

A natural gas tankless water heater is the kind of upgrade buyers and appraisers notice. It signals a modern, energy-efficient home, and with a lifespan of up to 20 years, a tankless unit typically outlasts a traditional tank water heater by roughly a decade — meaning your buyer isn't inheriting a water heater on its last leg. For homeowners planning to sell in the next several years, that's a tangible selling point during showings and inspections.

4. Save From Day One With Florida City Gas Rebates

As a Florida City Gas preferred vendor, Nextgen Plumbing and Gas helps customers take full advantage of the utility's appliance rebate program. Homeowners currently qualify for:

●      $550 back when replacing an existing gas water heater with a natural gas tankless unit

●      Up to $675 back when converting from an electric or other non-gas water heater to natural gas tankless

These rebates are paid directly through Florida City Gas's appliance rebate program and are one of the simplest ways to offset the upfront cost of an upgrade.

5. Spread the Cost Out — Financing Right on Your Gas Bill

Florida City Gas also offers a payment plan built specifically for tankless conversions, so you don't have to pay the full cost upfront. Qualifying homeowners can finance up to $2,500 of the project cost at $42.99 per month for 60 months, added directly to your monthly natural gas bill — no separate loan payment to track, and the rebate incentive is already factored into that monthly rate.

Nextgen Plumbing and Gas can help you check eligibility and walk through the paperwork as part of your installation, so financing is one less thing to figure out on your own.
