What a tankless water heater does
A tankless unit heats water as it passes through a heat exchanger, so there is no storage tank to leak or run out. That gives you steady hot water while the unit has enough capacity for the fixtures running.
These units are not maintenance free. Mineral scale clogs the heat exchanger over time, and the fix is a descale flush. If you are still comparing tank types, see our water heater installation page.
Why hard water matters for tankless
Barberton's latest water quality report lists hardness at about 170 mg/L, with a range of 100 to 250. That is hard water, and it leaves scale on the inside of a tankless heat exchanger.
- Error codes for flame failure or low flow
- Hot water that fluctuates during a shower
- Slow rise in water temperature
- Higher fuel use than before
- A rumbling or whistling sound from the unit
Left alone, scale cuts flow and efficiency and can shorten the unit's life. A yearly flush is cheap compared with a heat exchanger replacement.
How a descale flush works
We pump a mild descaling solution through the unit in a closed loop.
- 1
Isolate the unit
We close the service valves and connect hoses to the flush ports.
- 2
Circulate the solution
A pump moves descaling solution through the heat exchanger.
- 3
Rinse and clean the filter
We flush with clean water and clear the inlet screen.
- 4
Test the unit
We restore flow, check temperatures and clear any error codes.
If your unit lacks service valves, we can add them so future flushes are quick.
Repairs we do
Common tankless faults include failed igniters, flame sensors, flow sensors and condensate drain clogs. Many show up as an error code on the display, which helps us pick the right part.
If the unit has failed past repair, our replacement service can swap it for a new one. We tell you plainly when repair costs approach the price of a new unit.
Tankless or tank: a short comparison
The best choice depends on your home.
| Factor | Tankless | Tank |
|---|---|---|
| Hot water supply | Continuous within capacity | Limited by tank size |
| Space | Compact wall unit | Needs floor space |
| Maintenance in hard water | Yearly descaling needed | Yearly flush recommended |
| Typical lifespan | Often 20 years or more with care | Around 10 to 15 years |
| Upfront cost | Higher | Lower |
Venting, gas and electrical needs
A tankless gas unit often needs a larger gas line and special venting than a tank heater, and an electric unit can need a heavy circuit. We check these before quoting, because a good unit on a poor gas line gives poor results.
Permit rules vary, so ask the Barberton building department or Summit County before an install. We confirm which office applies.
What affects tankless pricing
Service prices follow the work needed.
Insurance does not usually cover tankless service. For a price on your unit, call (855) 575-2890.
Sizing a tankless unit for an Ohio winter
A tankless heater is rated by how many gallons per minute it can heat by a given temperature rise. Incoming water is colder in a northern Ohio winter, so the same unit delivers less flow in January than it does in July.
That is why we size from your coldest water and your busiest hour, not from a showroom label. Two showers and a dishwasher at once is a normal morning, and a unit that handles it in winter will handle it all year.

Call to book. Tell us the make and any error code.
Venting and gas guidelines
A gas tankless unit needs venting and a gas line sized according to the manufacturer's instructions and the codes that apply to the job. An undersized gas line is one of the most common reasons a new unit shuts down during a hot shower.
Hard water near 170 mg/L means a tankless heat exchanger collects scale faster, so a yearly descaling flush belongs in the maintenance plan.
Where we serve
We service tankless units in Barberton, Norton and Copley. If your unit has stopped altogether, see water heater repair for the urgent steps.
Tankless water heater questions
Once a year is a good baseline in hard water. Barberton's water is in the hard range, so we recommend keeping to that schedule.
It can if too many fixtures run at once for its capacity. Proper sizing at install avoids that.
Not required, but a softener reduces scale and helps the unit last longer in hard water.
Codes point to a sensor, igniter, flow or vent issue. Tell us the code and the model so we can bring the right part.
We service the major brands. Call with your model and we will confirm.
