Tankless Units in Greenwich Homes
In Greenwich, many tankless units hang in a basement beside the boiler. Condensate drains, sidewall vents and freeze protection all come into play here.
What we run into in Greenwich
- Basement units. Basement installs are common, often condensing units whose acidic condensate runs to a floor drain or a small pump.
- Snow on vents. After a big storm, a buried intake or exhaust is one of the first things to check when the hot water quits.
- Freeze damage. A hard freeze can split the pipes feeding a unit. Its built-in freeze protection only works while the unit still has power and gas.

These are the faults behind most calls for tankless water heater repair in Greenwich, CT. The display usually points at one of them.
Unit won't light
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
An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.
Display is blank
No power at the outlet, a blown fuse or a failed control board.
Frozen after a cold night
Lines feeding the unit froze, or freeze protection lost power.
Error code keeps coming back
A reset only clears the symptom. Repeated ignition or exhaust codes need a visit.

Greenwich Homes by the Numbers
Gas heats about 68% of homes in Greenwich, so gas tankless units, with their vent runs and gas-line sizing, are the usual case on a call. With a median build year of 1955, many homes in Greenwich were set up for a tank heater, which means a tankless unit often depends on a retrofitted gas line, vent run or drain. Greenwich is about evenly split between owners (around 52%) and renters, so calls come from homeowners and from landlords and property managers alike.
Greenwich covers about 4.8 square miles and holds roughly 14,528 residents, around 3,002 per square mile: suburban in density, with a mix of detached homes and townhomes. Among the 88 Connecticut places we cover, it ranks number 26 by population.
