A tankless water heater heats water on demand as it flows through the unit, delivering continuous hot water without storing it in a tank.
Tankless suits a lot of Orlando homes — until the hard water catches up with it. Done right, you get endless hot water and a smaller power bill. Done wrong, or never serviced, the heat exchanger scales up and starts throwing error codes. We install, repair, and descale tankless units, and we'll be straight about whether your home's gas or electric setup is ready for one.
Tankless and hard water have a complicated relationship in Orlando. The same minerals that scale a tank will scale a tankless heat exchanger faster, because the water is heated hard and quick. Skip the annual descale and you'll see dropping flow, then error codes, then a service call. The payoff is real though — no standby losses in a hot garage, and endless hot water for a busy house — as long as the unit gets maintained and the gas or electric supply was sized right at install.
A traditional water heater only holds about 40 gallons and takes at least 30 minutes to reheat once the tank runs dry. A tankless system heats water on demand — so you get endless hot water, a smaller footprint, fewer standby losses, and lower energy bills month after month.
If your tankless unit isn't functioning properly, we offer tankless water heater repair. Our trained technicians can fix nearly any make or model. When repair costs approach the price of a new unit, we'll be straight with you and recommend replacement instead of an expensive patch.
Installing, replacing or upgrading a tankless heater is a complex job that shouldn't be attempted without proper training and experience. We install a wide selection of leading brands, so you can choose the right unit — and we handle the gas, electrical and venting details correctly and to code.

For a lot of homes, yes — no standby loss in a hot garage, endless hot water, and a longer lifespan. The catch is our hard water: skip the annual descale and the savings vanish into a scaled-up heat exchanger.
Once a year in Central Florida, sometimes more on well water. Our mineral-heavy water scales the heat exchanger faster than the “every two years” guidance assumes. It's a quick service that prevents error codes and flow loss.
A properly sized gas unit can run a whole home; electric and smaller models suit point-of-use or smaller houses. Sizing is about peak simultaneous demand — how many hot-water fixtures run at once.
Most codes trace to scale buildup, ignition or venting faults, or a gas-supply issue. Scale is the usual Orlando culprit — descaling clears many codes; the rest we diagnose before replacing parts.
Often, yes. Gas tankless units need a larger gas line and proper venting; whole-home electric units can need a panel upgrade. We check your supply before quoting so there are no surprises mid-install.
It's endless, not instant — there's still a short wait for hot water to travel the pipe, same as a tank. A recirculation setup can shorten that wait if it matters to you.
Usually yes, but it's more than a swap — it can involve gas-line, venting, and electrical changes plus relocating connections. We'll tell you what your specific conversion actually requires and what it costs.
Electric installs run roughly $1,500–$3,500 and gas $2,500–$5,500, depending on what your home needs for gas, venting, or electrical. Descaling service is $150–$300. We quote firm first.
Typically 15–20 years — longer than a tank — but only with regular descaling. Neglected on Orlando water, a heat exchanger can fail far sooner, which is why maintenance is the whole game with tankless.
