Tankless Units in Raymore Homes
Most Raymore homes keep the tankless in the basement, beside the furnace. Hard water and cold winters are what wear these units down.
What we run into in Raymore
- 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. The water here carries a lot of minerals, and they settle as scale inside the heat exchanger. LC codes, overheat faults and water that will not get hot often trace back to it.

When people phone about tankless water heater repair in Raymore, MO, it is nearly always one of these problems. Each has a short list of causes.
Code 11, E003 or 111
A unit that clicks without lighting has an ignition, gas or venting fault, and each is checked in turn.
Drip from the cabinet
Water below a tankless can be a valve, a fitting, condensate or a failed exchanger. The source decides the cost.
Venting fault
Venting codes mean the unit can't breathe: a blocked termination, a nest, snow or a vent run that's too long.
Not as hot as it used to be
Scale on the heat exchanger, a weak gas supply or a thermistor reading wrong.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.
Display is blank
No power at the outlet, a blown fuse or a failed control board.

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.
What is the most common problem with tankless water heaters?
Scale buildup tops the list, then ignition trouble, then flow sensors and clogged inlet filters.
Is there a reset button on a tankless water heater?

Once a year for most homes, and twice a year on very hard water. Soft-water homes can stretch it, but never skip it for years.
