Tankless Water Heater Installation in Old Lyme: what is different here

Tankless units suit Old Lyme beach cottages where space is tight, and larger homes near Rogers Lake that want steady hot water. On well water, we fit isolation valves for descaling. For seasonal homes, we show you how to drain the unit before the winter shutdown.

How the job runs

  1. Measure your hot water demand

    We count fixtures and talk about how your household uses hot water at the same time, so the unit is sized right.
  2. Check gas and venting

    Tankless units draw a lot of gas while running. We check meter size, line size and where the vent can exit.
  3. Mount and pipe the unit

    The unit goes on the wall with isolation valves, which let us flush it later without cutting pipes.
  4. Vent and connect

    We run the venting, connect gas and water, and route the condensate drain if the unit needs one.
  5. Fire, test and set up

    We test flow at several taps, check for leaks, set the temperature and show you the controls.

Old Lyme questions

Shut off the fuel and power, close the water supply, then drain the unit through its service valves so no water sits inside to freeze. Some units also have a drain plug. Check the owner's manual first, because the steps vary by model.

Tankless for tankless replacement usually takes about half a day, and new tankless installation takes one to two days. Old Lyme is about 20 minutes from our shop, so the drive adds little to your visit. We confirm the time with you when you book.

Tankless units burn a lot of gas for a short time while hot water runs. A gas line sized for an old tank may not deliver enough, and the unit then shuts down or runs cool. We check line size and length against the unit's needs before installing.
