Platinum Air Care Makes It Easy to Go Tankless.

“We called about a leaking hot water tank and kept running out of hot water. Platinum Air Care recommended a Rinnai tankless system after we compared options and efficiency ratings. Now we have consistent hot water and better efficiency because we’re not heating a full tank when we don’t need it.” Brittney A. (Jan 2026)

Hot Water On Demand, Without Running Out

Endless hot water for busy mornings, long showers, and real life.

Tankless systems heat water only when you need it, reducing standby energy loss and helping you avoid the frustration of a tank running cold during peak demand.

How Tankless Works

  1. You open a hot water tap

  2. The unit senses flow and fires the burner

  3. Water is heated as it passes through the heat exchanger

  4. You get continuous hot water as long as there’s demand

The right model and proper sizing matter. A professional assessment ensures you get the performance you expect.

Is Tankless Right for Your Home?

Tankless is a great fit for many homes, but correct sizing and installation matter. A home’s bathrooms, simultaneous demand, and gas supply determine which unit is right.

Great fit if you want:

  • More consistent hot water

  • Improved efficiency

  • More space (wall-mounted)

  • A long-term upgrade from a tank

Considerations:

  • Some installs require venting changes

  • Some homes require gas line upgrades

  • Annual maintenance keeps performance strong
