Tankless Units in Delaware Homes

In Delaware, basement installs are the norm, and the water is hard. Scale on the exchanger and frozen condensate lines are frequent calls.

What we run into in Delaware

  • Basement units. Basement installs are common, often condensing units whose acidic condensate runs to a floor drain or a small pump.
  • Freeze damage. Freeze protection keeps the inside of a unit safe, not the exposed pipes under it. Uninsulated lines are where winter damage usually starts.
  • Hard water. With water this hard, a unit that has never been flushed is usually running hot inside and cold at the tap. Descaling is often half of the cure.

Repair or replace

Fix It or Retire It? Deciding in Delaware

Igniters, flame rods, sensors, fans, gas valves and boards are worth replacing on almost any unit. The hard call is a leaking or cracked heat exchanger on an older unit, because that part can approach the price of new.

Delaware Homes by the Numbers

17,347housing units
1993median year built
77%of homes heated by gas
62%owner-occupied

In Delaware about 77% of homes are heated with gas, which makes gas-fired tankless units, and the gas pressure and venting problems that come with them, the common repair. The median home here dates from 1993, so tankless units are a mix of original-era installs and newer replacements, and an older unit that has never been descaled is a frequent find. Roughly 62% of homes are owner-occupied and 70% single-family, so calls come from both homeowners and landlords.

With about 43,168 residents on roughly 20 square miles (near 2,133 per square mile), Delaware is spread out, with mostly detached homes on larger lots and longer runs between fixtures and the street. Among the 452 Ohio places we cover, it ranks number 22 by population.

How much does tankless water heater repair in Delaware, OH cost?

Most repairs cost an estimated $150 to $800, depending on the part. Descaling alone is estimated at $150 to $350, and a heat exchanger at $1,000 to $2,500. On hard water, a descale often goes with the repair and sits on the same written quote.

Is there a reset button on a tankless water heater?

Many do it through power: switch the unit off, wait, switch it back on. That clears a code, but a code that comes back means a part needs attention.

How long does a tankless water heater last?

A gas unit that is flushed regularly commonly lasts 20 years or longer. Electric tankless models usually give 7 to 10.

Why does my tankless water heater go hot then cold?

A second or two of cold after the tap reopens is normal start-up. If the water swings while it runs, look at low flow, scale or the flow sensor.
