Tankless Water Heater Installation and Repair in Columbia, SC
A tankless water heater heats water only when a fixture asks for it, firing a high-output burner or element as water flows through a heat exchanger. There is no stored tank to deplete, no standby heat loss keeping forty gallons warm overnight, and no tank shell to rust through and flood the closet. 2nd Wind Heating & Air Conditioning installs, repairs, and maintains tankless water heaters in Columbia, SC and across the Midlands, with options and prices presented before installation begins.
Tanks cost less up front and tolerate hard water better; tankless units run longer service lives, save standby energy, and never run out mid-shower. The right answer depends on household demand, fuel, water chemistry, and installation constraints, and our water heater services team quotes both paths when a homeowner is deciding between them. Gas-fired installations that need supply work are handled through our gas line services.

Tankless Installation
Installation starts with two calculations: the peak flow the household demands at once, measured in gallons per minute across simultaneous fixtures, and the temperature rise the unit must produce from incoming groundwater. Gas units also frequently need a larger gas line and dedicated venting, and we confirm the supply can feed the burner before quoting, because an undersized gas line is the most common cause of a tankless unit that underperforms from day one. The finished installation is set up, tested at multiple fixtures, and documented.
Tankless Repair and Descaling
Tankless failures announce themselves as error codes, temperature swings, or declining flow, and the most common underlying cause is scale. Minerals precipitate inside the heat exchanger’s narrow passages, insulating the water from the burner and choking flow. Periodic descaling flushes the exchanger with a cleaning solution and restores output, and it is the single maintenance task that most extends the unit’s life. Homes on mineral-heavy well water scale faster, and pairing the unit with our water softener services slows the clock considerably.

FAQs
Does a tankless water heater really never run out of hot water?
It never depletes a stored supply, so it runs indefinitely at or below its rated flow. Exceed that flow with too many simultaneous fixtures and the temperature drops, which is why sizing to your household’s peak demand is the whole game.
How long does a tankless unit last compared to a tank?
Twenty years is a reasonable expectation for a maintained tankless unit, roughly double a typical tank, partly because there is no stored-water tank shell to corrode. Descaling on schedule is what protects that lifespan.
Why is my tankless water heater flashing an error code?
Common causes are scale buildup in the exchanger, gas supply or venting problems, and flow sensors reading below the activation threshold. The code narrows the search, and diagnosis confirms the cause before any parts are quoted.
Will a tankless heater work for a large household?
Yes, sized accordingly, and large demand is sometimes met with a higher-capacity unit or two units in parallel. The peak-demand calculation tells us which configuration your fixtures actually require.
How often should a tankless unit be descaled in the Midlands?
Annually is the safe default, stretching longer for homes with soft or softened water and shortening for mineral-heavy wells. Declining flow at hot taps is the signal it is overdue.
