INSTALLATION

Choosing the right tankless water heater for your home

Tankless water heaters work differently from traditional tanks, heating water only as it is needed rather than storing and reheating it throughout the day. This makes them more efficient, longer lasting, and better suited for homes with frequent hot water demands.

Washington Energy Services installs tankless water heaters from trusted manufacturers including Navien and Rinnai.

A few things worth knowing as you consider your options:

  • Gas tankless units offer high heating capacity and work well for homes with frequent hot water demands and an existing gas connection.
  • Electric tankless units are better suited for commercial applications. Because of the high electricity demand required to heat water instantly, they rarely make sense for residential homes.

Make your tankless water heater project work for your budget

We offer flexible financing options to help you get started without the wait.

REPAIR

Getting your tankless water heater back to reliable operation

A tankless system that isn’t working properly can mean inconsistent water temperatures or no hot water at all. Our licensed plumbers are trained to accurately diagnose issues and restore your hot water without unnecessary delays.

Some of the most common problems we see include:

  • Inconsistent or fluctuating water temperature
  • Reduced or insufficient flow
  • Ignition or pilot light issues on gas units
  • Error codes displayed on the unit
  • Mineral or scale buildup affecting performance
  • Unit not turning on or responding

Our licensed plumbers service most major makes and models and focus on identifying the root cause and recommending the right repair for your home and your equipment.

MAINTENANCE

Keep your tankless water heater running at its best

Regular maintenance is one of the simplest ways to extend the life of your tankless water heater and keep it running efficiently. We recommend an annual tune-up to flush mineral buildup, check key components, and catch small issues before they turn into bigger, more costly repairs.

Our licensed plumbers service most major makes and models and are trained to spot early signs of wear before they become larger problems.

Tankless water heater maintenance can be combined with other service visits to save you time. If you want to stay ahead of maintenance and reduce long-term costs, annual service can be included as part of our Guardian Maintenance Plan at a discounted rate.
