Tankless Units in Cambridge Homes
In Cambridge, 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 Cambridge
- 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.

Call (380) 273-8196Tankless Problems We Fix Around Cambridge
The list below covers what we find on most visits for tankless water heater repair in Cambridge, MN, from ignition codes to drips under the cabinet.
Code 11, E003 or 111
No ignition usually means gas pressure, a worn igniter, a dirty flame rod or a blocked vent. Each is tested.
Water under the unit
Drips come from service valves, fittings, the relief valve, the condensate line or the heat exchanger itself.
Code 10 or E110
Venting codes mean the unit can't breathe: a blocked termination, a nest, snow or a vent run that's too long.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.
LC code on a Rinnai
The unit is reporting scale buildup. It needs a descale, and soon.
Frozen after a cold night
Lines feeding the unit froze, or freeze protection lost power.

Call (380) 273-8196How much does tankless water heater repair in Cambridge, MN 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.
Can a tankless water heater be repaired?
Yes, in most cases. Igniters, flame rods, flow sensors, thermistors, fans, gas valves and boards are all replaceable, and scale can be descaled. A leaking heat exchanger on an old unit is the main exception.
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.
