Is a Tankless Water Heater Right for Your Tempe Home?

Tankless water heaters can be an excellent option for many homes, but proper sizing is critical. A system that is too small may struggle to keep up when several fixtures require hot water at the same time.

Household size, bathrooms, fixture flow rates, incoming water temperature, fuel availability, plumbing condition, peak hot water usage, and installation location all influence system selection.

Empire Plumbing & Air Conditioning explains your options clearly and helps you compare tankless installation with traditional water heater replacement so you can choose the right solution for your home and budget.

Proper Tankless Water Heater Sizing Matters

Tankless water heaters must be selected based on how much hot water your household may require at one time and how much temperature increase the equipment needs to provide.

We Consider:

  • Number of bathrooms
  • Shower and fixture usage
  • Dishwasher and appliance demand
  • Peak simultaneous hot water use

We Also Evaluate:

  • Available gas supply or electrical capacity
  • Existing water heater location
  • Venting requirements for gas equipment
  • Plumbing layout and installation access

Our Tankless Water Heater Installation Process

1. Evaluate Your Home

We review your current water heater, plumbing system, fuel source, household hot water needs, and installation location.

2. Recommend Equipment

Our plumber explains suitable tankless options based on household demand and installation requirements.

3. Install the System

The equipment is installed with the required plumbing, fuel, venting, electrical, drainage, and control connections.

4. Test Performance

We test system operation, water flow, temperature, and hot water performance before completing the installation.

Converting From a Tank Water Heater to Tankless

A tank-to-tankless conversion can require more than replacing one piece of equipment with another. Tankless systems have different flow, fuel, venting, electrical, drainage, and installation requirements.

Depending on your Tempe home and the selected equipment, installation may require changes to gas piping, venting, electrical service, condensate drainage, water connections, equipment mounting, or service access.

Our plumbers evaluate these requirements before installation so you understand the work needed to support your new system properly.

Arizona Hard Water & Tankless Water Heaters

Arizona hard water can contribute to mineral scale inside tankless water heating equipment. As mineral deposits accumulate, they may restrict water flow and affect heat-transfer performance.

Tankless systems use compact heat exchangers and internal water passages, which makes routine maintenance important for dependable long-term operation.

Periodic flushing or descaling can help reduce mineral accumulation and support system performance.

Tankless vs. Traditional Tank Water Heaters

Tankless Water Heater

  • Heats water on demand
  • Compact wall-mounted design
  • Requires proper flow-rate sizing
  • May require gas, venting, plumbing, or electrical upgrades

Traditional Tank Water Heater

  • Stores a fixed amount of hot water
  • Requires more floor space
  • May provide a simpler replacement in an existing tank setup
  • Available in gas and electric configurations

Maintaining Your New Tankless Water Heater

Routine maintenance helps protect your investment after installation. The appropriate maintenance schedule depends on water quality, household usage, equipment type, and manufacturer recommendations.

Tankless maintenance may include flushing or descaling the heat exchanger, cleaning filters, checking plumbing and fuel connections, reviewing error codes, inspecting venting, and confirming overall system operation.

Staying current with maintenance can help reduce mineral buildup and identify developing problems before they interfere with hot water performance.
