Efficiency Matters: Making The Most Of Your Water Heater

Making the most out of your water heater starts by lowering the thermostat to 120°F. After that, it’s a matter of being mindful and knowing when to seek water heater repair in Surprise, AZ.

At Trident Plumbing & Drain, we know that efficiency is maintenance-driven. Here, we discuss how homeowners can maximize their water heater’s performance

Set the Right Temperature (Not Higher)

Hot water is one of the largest energy expenses in your home. According to energy studies, it can account for roughly 15 to 20% of residential utility costs. Yet most homeowners ignore the water heater until it stops working.

Many water heaters are set to 140°F by default. That’s higher than most households need.

Lowering the thermostat to 120°F:

• Reduces standby heat loss
• Lowers energy consumption
• Minimizes scald risk
• Slows mineral scaling

In Surprise, where groundwater carries significant mineral content, scaling accelerates at higher temperatures. Keeping the setting at 120°F improves both efficiency and lifespan.

Flush Sediment—Every Year

Arizona water is hard. Hard water leaves sediment inside tank-style water heaters.

Sediment forms an insulating layer at the tank bottom. The burner or heating element must work harder to heat water through that layer.

Results include:

• Increased gas or electric usage
• Rumbling or popping sounds
• Slower recovery times
• Shortened tank life

Annual flushing is an excellent way to treat buildup before it hardens. If your system hasn’t been flushed in years, efficiency is already declining.

Install a Water Softener

Hardness levels in Surprise often exceed 10 grains per gallon. That’s classified as very hard water. And, unsurprisingly, hard water is a primary efficiency killer.

A water softener:

• Reduces scale buildup
• Extends water heater lifespan
• Improves heating efficiency
• Protects plumbing fixtures

Without softening, heating elements in electric units fail faster. Gas units develop thick sediment beds. Either way, energy use climbs.

Insulate Pipes and the Tank

If you have a tank-style heater in a garageheat loss can occur even in mild winters.

Insulating reduces standby heat loss. Consider insulating:

• Exposed hot water pipes
• The first 6 feet of the cold inlet pipe
• The tank itself (if older and uninsulated)

Consider a Recirculation Pump

Gallons of water are wasted if you wait 30 to 60 seconds for hot water at distant fixtures. That’s why a hot water recirculation system delivers hot water faster and reduces waste.

In desert climates where water conservation matters, efficiency includes both energy and water use.

Know When Replacement Improves Efficiency

If your unit is over 10 to 12 years old, efficiency declines even with regular water heater maintenance.

Modern systems offer:

• Higher Energy Factor (EF) ratings
• Better insulation
• Improved burner or element design
• Smart control options

Sometimes, the most efficient move is proactive water heater replacement.

FAQs: Water Heater Efficiency in Surprise, AZ

What temperature should my water heater be set to?

120°F for most households balances safety and efficiency.

How often should I flush my tank?

Once per year, especially in hard water regions.

Does hard water reduce efficiency?

Yes. Scale buildup forces the system to work harder.

Are tankless water heaters more efficient?

Yes, but they require descaling maintenance in hard water areas.

Maximizing water heater efficiency does not stop with just one fix. Homeowners must set the correct temperatures. 

• Set the correct temperature
• Flush sediment annually
