Tankless water heater installation, repair, and replacement

What a tankless water heater actually buys you

Tankless is not right for every house. Where it fits, it changes how the household uses hot water.

• Hot water that does not run out mid-shower
• A fraction of the floor space of a tank
• Lower standby energy loss month to month
• Longer service life than a tank unit
• No tank sitting full of Shore well sediment
• Wall-mounted, away from flood risk

When to service a tankless water heater and when to replace it

A tankless unit outlasts a tank, so most of what we get called to is service rather than replacement. These are the three answers.

Descale when the output has dropped off

Scale on the heat exchanger is the most common reason a tankless unit stops delivering, and it is service rather than a fault. Hard well water makes it happen faster here. See tankless repair and descaling.

Repair when it is a sensor, a fan or an igniter

An error code usually points at one component, and parts for Rinnai and Navien units are available. On a unit that was installed properly, a repair is nearly always the cheaper answer.

Replace when it was undersized from the start

If the unit was never sized for what the household draws at once, no amount of service fixes that, and the same goes for one on a gas line that cannot feed it. See tankless installation and replacement.

The parts of a tankless install people skip

Most tankless problems trace back to a shortcut at installation. These are the ones that matter, and the full job is on tankless installation and replacement.

A real load calculation

Sized on how much hot water your household actually draws at once, not on the square footage of the house.

Gas line and venting

A tankless unit usually needs a larger gas line and its own venting. We do both, to code, as part of the job.

Water treatment first

Hard well water scales a heat exchanger fast. We test the water and tell you if treatment should come first.

Descaling and maintenance

Periodic descaling keeps the unit at full output. We set the schedule and can carry it out each year. See tankless repair and descaling.
