Tankless Water Heaters in the Desert: Are They Worth It?
Thompson Family Plumbing is your go-to choice for residential plumbing repair and installation throughout Lake Havasu City, AZ and Hesperia, CA.
Tankless Water Heaters: Are They Worth It for Desert Homes?
If you live in Lake Havasu, AZ, or Hesperia, CA, you’ve probably wondered whether Tankless Water Heaters are worth the investment. Desert climates present unique plumbing challenges, including hard water, high summer temperatures, and increased demand for hot water throughout the year.
Unlike conventional storage tank systems, Tankless Water Heaters heat water only when you need it. This on-demand technology offers improved energy efficiency, an endless supply of hot water, and a compact design that appeals to many homeowners.
At Thompson Family Plumbing Heating and Air, we help homeowners determine whether Tankless Water Heaters are the best solution for their household’s hot water needs. Here’s what you should know before making the switch.
Tankless Water Heaters: How Do They Work?
Unlike traditional water heaters that continuously store and heat water in a large tank, Tankless Water Heaters heat water instantly as it flows through the unit.
When you turn on a hot water tap, powerful heating elements or gas burners warm the water before it reaches your faucet or shower.
Benefits include:
- Endless hot water
- Improved energy efficiency
- Compact, wall-mounted design
- Lower standby energy losses
- Longer equipment lifespan
If you’re considering an upgrade, our Water Heater Services can help you determine the right system for your home.
Why Tankless Water Heaters Are Ideal for Desert Homes
Desert homeowners often experience unique plumbing conditions, making Tankless Water Heaters an excellent option for many households.
Lower Energy Bills
Traditional storage water heaters constantly reheat stored water, even when no one is using hot water.
Because Tankless Water Heaters operate only when hot water is needed, they eliminate standby heat loss and can significantly reduce energy consumption.
According to the U.S. Department of Energy, homes using less than 41 gallons of hot water daily can improve energy efficiency by 24%–34% when switching to tankless systems.

Endless Hot Water
One of the biggest advantages of Tankless Water Heaters is that they provide continuous hot water.
Whether multiple family members shower back-to-back or you’re running the dishwasher while doing laundry, you won’t have to wait for a storage tank to refill.
Save Valuable Space
Many desert homes have limited utility room space.
Because Tankless Water Heaters mount directly on the wall, they free valuable floor space that would otherwise be occupied by a bulky storage tank.
Things to Consider Before Installing Tankless Water Heaters
Although Tankless Water Heaters offer many benefits, homeowners should understand a few important considerations before installation.
Higher Initial Investment
The upfront cost of Tankless Water Heaters is typically higher than conventional storage systems.
Installation may require:
- Gas line upgrades
- Electrical improvements
- New venting systems
- Water line modifications
Although installation costs are higher, many homeowners recover part of their investment through lower monthly utility bills.
Flow Rate Capacity
Every tankless system has a maximum flow rate.
If several showers, washing machines, and appliances operate simultaneously, one unit may not produce enough hot water.
A licensed plumber can calculate your household’s demand and recommend the proper size or multiple units if necessary.
Hard Water Maintenance
Hard water is common throughout desert regions.
Mineral deposits can build inside Tankless Water Heaters, reducing efficiency over time.
Regular descaling and flushing help prevent scale buildup and extend the lifespan of the system.
The EPA also recommends maintaining water-using appliances to improve efficiency and conserve water.

Longer Service Life
With proper maintenance, Tankless Water Heaters often last 20 years or longer.
Traditional storage water heaters generally last between 10 and 15 years.
That longer lifespan makes tankless systems an attractive long-term investment for homeowners planning to stay in their homes.

They’re especially beneficial if you want:
- Lower monthly energy costs
- Endless hot water
- More storage space

Your family’s water usage, household size, plumbing layout, and budget should all be considered before choosing a new water heater.

“Price was more than reasonable, especially last minute”
What a great local family company. Had a little issue today (Saturday). Gave them a call. The lady said she would have someone here between 3 & 5. It was at 1 when I called. 3:00 on the nose Don was here. Don was very friendly and had the broken pipe fixed in no time at all. The price was more than reasonable, especially last minute on a Saturday.

“Took care of it in no time”
Plumbing technician Dean Taylor came over last week to set up a line so I could get a dishwasher installed. I didn’t have the proper setup but he took care of it in no time! Now the installers will have no problem doing it. He was very knowledgeable and professional. I will definitely have him come back for other plumbing jobs. From start to finish everyone I spoke to was very helpful! Their customer service is outstanding!

“Gave me great peace of mind”
Great experience with TFP! They were super professional and friendly, exactly on time, fixed the issue, AND were inexpensive. I received a text when to expect them with a picture of my two technicians (Dean & Kade) AND their license numbers included in the text. This gave me great peace of mind as I am a woman that lives alone. I highly recommend Thompson Family Plumbing!
