Tankless Units in New London Homes
Basement units are standard in New London. A buried vent after a storm and a condensate pump that quits are two of the most common no-hot-water calls.
What we run into in New London
- Basement units. Many units here sit in the basement with PVC pipes venting out through the rim joist, and the condensate has to drain somewhere sensible.
- 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. Freeze protection keeps the inside of a unit safe, not the exposed pipes under it. Uninsulated lines are where winter damage usually starts.

Most requests for tankless water heater repair in New London, CT start with one of the symptoms below, and most end with a single part or a descale.
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.
Noisy or whistling
Scale, a struggling fan or a gas regulator issue, each of which shows up on testing.
Error code keeps coming back
A reset only clears the symptom. Repeated ignition or exhaust codes need a visit.
Shuts off mid-shower
Flow drops below what the unit needs to keep firing: a clogged filter, aerator or shower cartridge, or a sensor misreading.

New London Homes by the Numbers
Heating in New London splits between gas (about 46% of homes) and electricity (about 31%), and tankless repairs follow the same split. Housing here is older (median year built 1947), 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. Only about 40% of homes are owner-occupied, so many calls come from landlords and property managers, who usually want the cause and the price in writing.
With about 27,199 residents on roughly 5.6 square miles (near 4,848 per square mile), New London is suburban in density, with a mix of detached homes and townhomes. It is number 21 by population of the 88 Connecticut places on our service list.

Call (380) 273-8196How much does tankless water heater repair in New London, CT 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. Freeze repairs depend on what split, and are priced once the damage is seen.
How often should a tankless water heater be flushed?
Most makers call for a flush every year, and every six months on very hard water. On very soft water the gap can be longer, but skipping it for years invites scale faults.
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.
What is the most common problem with tankless water heaters?
Scale in the heat exchanger, followed by ignition faults and flow sensor or filter problems. All three usually show up as a code or as water that won't stay hot.
