Tankless Water Heater Installation & Repair in Davie, FL
Endless hot water, lower energy cost, and a unit that only runs when you need it. We install, size, and repair gas and electric tankless water heaters across Davie and Broward County.
A tankless water heater heats water only when you turn on a fixture, so there is no stored tank keeping 40 or 50 gallons hot all day. The unit senses flow, fires, and runs cold incoming water through a heat exchanger. Turn the fixture off and the unit stops. That is the whole idea: hot water on demand, no standby loss, and no running out.
Two fuel types, and the right one for your house is mostly decided by what is already there. A gas tankless unit burns natural gas and needs a gas line sized to its full firing rate, plus venting for the exhaust. An electric tankless unit has no exhaust, but it draws a large amount of power, and an older electrical panel may not have the capacity to feed it.
Sizing a tankless unit is about flow rate, not gallons. We add up the fixtures that can run at the same time, each with its own gallons-per-minute rating, and then figure the temperature rise the unit has to deliver. South Florida helps here: the incoming ground water is already warm, so the unit does not have to lift the temperature as far, and a given model can serve more fixtures at once than it could somewhere with cold incoming water.
For a gas tankless installation we size and run the gas piping, install the venting the unit requires, and pull the permit and arrange the inspection. The venting has to be rated for the unit and routed correctly, and the gas line has to feed the unit at full fire without starving the other gas appliances in the home. None of that is optional, and it is all part of the install.
For an electric tankless unit the question is electrical capacity. The unit draws a large, steady load, and the panel and the wiring have to be up to it. Any electrical panel upgrade or new circuit is done by a licensed electrician. We handle the plumbing side: the unit, the water connections, and the permit, finished to the inspection.
A tankless unit is low maintenance, not no maintenance. The heat exchanger is a narrow passage, and mineral scale builds up inside it over time. Once a year we descale the unit with a pump and a cleaning solution that flushes the exchanger and clears the scale, so the unit keeps heating at full output. Skipping it is the most common reason a tankless unit slowly stops delivering hot water.
We also repair existing tankless units. A unit that has stopped heating, is throwing an error code, or only runs warm is often a single failed part: a flow sensor, an igniter, a circuit board, or a scaled heat exchanger. We diagnose before we recommend replacement. And if you are still weighing tankless against a tank, the honest pros are endless hot water, a longer service life, and lower operating cost; the honest cons are a higher up-front price and the gas or electrical work a tank replacement would not need.
What It Is and When You Need It
Tankless water heater installation is the work of mounting the unit, connecting it to the water supply, and — for a gas unit — running the gas piping and the venting, or for an electric unit, confirming the panel and wiring can feed it. Tankless repair is diagnosing a unit that has stopped heating, is throwing an error code, or is only delivering warm water, and replacing the failed part rather than the whole unit.
You need this page when you are building new and want hot water on demand, when your tank has failed and you are weighing a tankless replacement, when you are running out of hot water and want to stop scheduling showers around a 50-gallon tank, or when the tankless unit you already have has stopped working and you want it diagnosed before anyone quotes you a new one.
It is also the right call when you want to cut the standby energy a tank burns all day, or when you are finishing a garage or a closet and the wall space a tank takes up is better used for something else. A tankless unit mounts on a wall and frees up the floor a tank would sit on.
How We Do It: Sizing First, Then the Smallest Repair That Fixes It
Every tankless job starts with sizing. We walk the house, list the fixtures that can run at the same time, add up their gallons per minute, and figure the temperature rise the unit has to deliver off the incoming water temperature. That number sets the unit size. Undersize a tankless unit and two showers will starve it; oversize it and you pay for capacity you never use. South Florida's warm incoming water works in your favor here, because the rise is small and a given unit serves more.
For a gas install, we size and run the gas piping so the unit gets its full volume at fire without dropping the pressure to the other gas appliances, and we install the venting rated for the unit, routed to clear the exterior wall and any windows or intakes. The permit is pulled and the inspection scheduled in our name. For an electric install, we confirm the panel and the wire can carry the load; if they cannot, any electrical panel upgrade or new circuit is done by a licensed electrician, and we handle the plumbing side — the unit, the water connections, and the permit.
For a repair, we read the error code off the unit first, then test the parts that code points at. A gas unit that will not fire is often the igniter or the flame sensor; an electric unit that only runs warm is often a scaled heat exchanger or a bad flow sensor; a unit that trips its breaker is drawing past the circuit. We descale a scaled heat exchanger with a pump and hoses that circulate a cleaning solution through it, and we replace the failed part when the diagnosis calls for it. No brand names to push — we fix what is in front of us.
Annual descaling is its own small service. We isolate the unit, connect a pump and two hoses, and circulate a descaling solution through the heat exchanger until the scale clears, then flush it with clean water. It takes less than an hour and it is the single thing that keeps a tankless unit heating at full output for the life of the unit.
What Affects the Cost
A tankless install is quoted flat-rate after we size the unit and look at the site, and the number follows your house rather than a menu. What moves it: gas versus electric, since a gas unit brings the gas piping and the venting and an electric unit may bring a panel upgrade; the size of the unit, which follows the flow rate and the temperature rise your fixtures demand; whether the unit is replacing a tank in the same spot or moving to a new wall, because a relocation means new water lines and a new gas or electrical run; the venting route on a gas unit and how far it has to travel to the exterior; the electrical capacity you already have, since a panel that needs upgrading adds an electrician's work; the permits and inspection the jurisdiction requires; and whether the call is a planned install or an emergency because the old tank just failed.
A repair is quoted after the diagnosis, and the number follows the failed part. A descale is a fixed, small service. We give you the price before any work starts, and if the diagnosis turns up something different from what we expected, we stop and explain before continuing.
