Hot water on demand

Tankless water heaters in Peoria, AZ

If your conventional water heater needs to be replaced, it is a good time to consider whether a tankless system fits your home. Unlike a traditional heater that keeps water hot in a storage tank, a tankless heater heats water as it passes through the unit.

Trident Plumbing & Drain helps homeowners in Peoria, Glendale, Litchfield Park, Surprise and surrounding communities compare their options. We provide advice around your situation, including whether repairing the current heater or installing a different system makes sense.

Before you switch

Is a tankless water heater right for your home?

A compact tankless unit can take up less space than a conventional storage heater. Removing the large storage tank also changes how hot water is supplied. The recommendation still needs to account for the home and the amount of hot water required at one time.

Tell us whether the current heater struggles only during busy periods or cannot keep up with normal use. We review the available utilities, installation location and hot water demand before suggesting a conversion.

  • A current heater that needs replacement or repeated attention.
  • Interest in reducing the standby heating associated with a storage tank.
  • Available space and the requirements of the proposed tankless unit.
  • Showers and appliances that commonly use hot water together.

Understand the difference

Energy efficiency and hot water demand

Tankless heaters avoid keeping a large tank of water hot between uses. That can reduce the standby energy losses associated with storage water heaters. Actual energy use and operating cost depend on the unit and how it is used.

On-demand heating does not mean unlimited output to every fixture at once. The heater must be sized for the flow and temperature rise needed by the home. We compare the proposed system with your routine rather than promise that one model will suit every household.

Keep up with care

Tankless water heater maintenance

Tankless water heaters still need maintenance. Trident’s service can include checking filters, flushing or descaling as appropriate and testing safety and performance. The scope and schedule should follow the requirements of your particular model and water conditions.

If you have not had the heater serviced, keep the model information available when booking. Tell us about warning codes, fluctuating temperatures or reduced performance so those concerns can be evaluated rather than treated as routine maintenance alone.

  • Water-line filter inspection and cleaning or replacement as needed.
  • Air-filter attention where the model includes one.
  • Flushing or descaling appropriate to the unit.
  • Safety and performance checks.

You do not have to decide on a replacement before calling. Our team can inspect a tankless system that is no longer providing consistent hot water and explain the findings. Note whether the issue affects one fixture or the whole home, and when you first noticed it.

When replacement is the appropriate next step, we explain the options and installation requirements. The aim is to choose equipment that addresses your household’s needs, with clear information about future maintenance.

Our 12 year old water heater was leaking. I called and spoke with Shelby who was able to dispatch a technician immediately, same day… Tyler arrived on time, worked efficiently and cleaned up after himself.

Ask our team
Do tankless water heaters need maintenance?

Yes. Filters, mineral buildup and performance still need attention. Trident can help you follow a service schedule appropriate to your model, its instructions and your water conditions.

Can a tankless heater serve several fixtures at once?

A correctly selected unit can serve the demand it is designed for. The number of fixtures running together and the required temperature rise affect sizing, so we assess household use before recommending a system.

Should I replace my tank heater with a tankless model?

That depends on the condition of your existing heater, hot water demand and the installation requirements at your home. We can compare repair, tank replacement and tankless options.
