What to Look for When Buying a Water Heater 

A Phoenix Homeowner’s Guide to Choosing the Right Water Heater 

Choosing a new water heater is a big decision — one that affects your comfort, energy bills, and daily routine for years to come. Whether you’re replacing a failed unit or upgrading to something more efficient, understanding your options is key. At Robins Plumbing, we help Phoenix homeowners choose water heaters that match their home, lifestyle, and long-term goals — not just what’s on the shelf.

Here’s what you should consider before purchasing a new water heater. 

 

1. Type of Water Heater: Tank vs. Tankless vs. Hybrid

The first step is choosing the right type of system for your home. 

Tank Water Heaters (Traditional) 

Tank-style water heaters store and continuously heat a set amount of water. 

Best for:

• Larger households
• Lower upfront cost
• Simple, reliable systems 

Considerations:

• Can run out of hot water
• Higher standby energy loss 

 

Tankless Water Heaters (On-Demand) 

Tankless systems heat water only when needed. 

Best for:

• Energy efficiency
• Endless hot water
• Smaller footprint 

Considerations:

• Higher upfront investment
• May require upgrades to gas lines or electrical systems 

 

Hybrid Water Heaters (Heat Pump) 

Hybrid systems use surrounding air to heat water, making them extremely efficient. 

Best for:

• Energy savings
• Long-term cost reduction
• Environmentally conscious homeowners 

Considerations:

• Require space and airflow
• Higher initial investment 

 

2. Size and Capacity Matter More Than You Think

Choosing the wrong size water heater is one of the most common mistakes homeowners make. 

Too small:

• You run out of hot water 

Too large:

• You waste energy and money 

In Phoenix homes, sizing depends on: 

• Number of occupants
• Simultaneous water use (showers, laundry, dishwasher)
• Peak usage times 

A professional evaluation ensures you get the right fit — not guesswork. 

 

3. Energy Efficiency = Long-Term Savings

Energy-efficient water heaters can significantly reduce your utility bills over time. 

Look for: 

• Energy Star® certification
• High efficiency ratings
• Hybrid or tankless technology 

Hybrid water heaters, in particular, are known for delivering substantial savings over the life of the unit. 

 

4. Fuel Type: Gas vs. Electric

Choosing the right fuel type depends on your home setup and goals. 

Electric Water Heaters 

• Often Energy Star rated
• Lower upfront cost
• Easier installation
• Great for hybrid systems

Gas Water Heaters 

• Typically lower operating costs
• Faster recovery rates
• Available in tank and tankless models 

Considerations:

• Requires gas line access
• Venting requirements 

A professional plumber can help determine what makes the most sense for your home. 

 

5. Installation Matters More Than the Unit Itself

Even the best water heater can underperform if installed incorrectly. 

Proper installation ensures: 

• Safety
• Efficiency
• Longevity
• Code compliance 

At Robins Plumbing, we ensure every system is installed to perform at its best from day one. 

 

6. Don’t Forget Maintenance and Lifespan

Your water heater is not a “set it and forget it” appliance. 

Regular maintenance — including annual flushing — helps: 

• Extend lifespan
• Improve efficiency
• Prevent sediment buildup
• Reduce the risk of failure 

Neglecting maintenance can lead to leaks, inefficiency, and even emergency situations. 

If your system fails unexpectedly, our 24-hour emergency plumbing services in Phoenix are always available.
