TANKLESS WATER HEATERS

Is a tankless water heater right for this house?

A tankless heater warms water only when a tap opens, so it skips the standby losses of keeping a tank hot. The U.S. Department of Energy estimates 24–34% better efficiency for homes using 41 gallons a day or less. Gas tankless units need correct venting, gas line sizing, and yearly descaling.

WHAT TO LOOK FOR

Signs you might notice.

An aging tank (often 10+ years) or rust at the base

Wanting space back in a closet or garage

WHAT WE DO ABOUT IT

We size the unit to your peak demand, check the gas line and venting, and set up a descaling routine so it lasts.
