Tankless Units in Andover Homes
Most Andover homes keep the tankless in the basement, often a condensing unit venting through the side wall. Snow against that vent and clogged condensate lines are winter regulars.
What we run into in Andover
- Basement units. In a basement install, a clogged condensate trap or a failed pump can shut the unit down with a code long before anyone sees water.
- Snow on vents. Snow drifting against a sidewall vent will stop a unit cold with a venting code until the termination is cleared.
- Freeze damage. Cold snaps do damage here when the power drops overnight. A frozen line or a cracked fitting under the unit is a repair we see after every deep freeze.

These are the faults behind most calls for tankless water heater repair in Andover, MA. The display usually points at one of them.
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.
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.

Fix It or Retire It? Deciding in Andover
Gas tankless units commonly last 20 years or more with flushing, so a single failed part rarely means a new heater. A failed exchanger outside its warranty, on a unit past 15 years, is where replacement starts to win.
Tell us the brand, roughly how old the unit is and what it is doing when you call (380) 273-8196. If a repair is a poor spend, you will be told so.

Andover Homes by the Numbers
In Andover about 75% 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. Housing here is older (median year built 1938), and older homes were plumbed and vented for tank heaters, so tankless retrofits often meant new gas lines, venting or a condensate drain, which are common places for faults to start. About 70% of homes are owner-occupied and about 59% are single-family, so most repair decisions here are the homeowner's own.
With about 9,261 residents on roughly 3.7 square miles (near 2,510 per square mile), Andover is suburban in density, with a mix of detached homes and townhomes. Among the 126 Massachusetts places we cover, it ranks number 65 by population.

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.
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.
