Tankless
Water Heaters

The Valley’s Tankless Water Heater Installation Experts

Tankless or on-demand water heaters heat water only when it’s needed, eliminating the need for a storage tank and the standby losses associated with constantly maintaining a tank full of hot water. Most tankless water heaters have a life expectancy of about 20 years, much longer than any conventional tank-type water heater. They also eliminate the risk of tank leaks and water damage so contact us today to schedule your tankless water heater installation.

How It Works

When you turn on the hot water tap, cold water is drawn through a pipe into the unit and heated either by an electric heating element or a gas burner. The hot water never runs out, but the flow rate may be limited. Tankless water heaters typically deliver hot water at a rate of 2 – 5 gallons per minute. Gas-fired models will generally have higher flow rates than electric models.

 

 

Benefits of Tankless Water Heaters

  • Operating costs are up to 40% less
  • Endless supply of hot water – water is heated as fast as it is used
  • No waste of energy for reheating water over and over
  • Small size permits flexible installation options inside and out
  • Longer service life – 20 years average
  • Unlike many competitors’ products, Navien tankless water heaters are engineered to work with “looped” recirculating plumbing installations
  • Endless Supply of Hot Water

A tankless water heater will save you money on your energy bills, but it also provides other benefits as well. As their name inplies, tankless water heaters do not have a tank, which can take up a lot of space in your home. You can use that space for other things, such as storage or even a play area. With a tankless water heater, you will never have to worry about running out of water in the middle of a shower again. With traditional water heaters, once the tank is empty, you have no more hot water until it fills and heats up again. However, with a tankless heater, the hot water just keeps coming. They have also proven to have longer lifespans than traditional tanks. In fact, they may last up to 15 years longer. This, plus the energy savings, despite the higher upfront costs make it a good investment. Isn’t it time for your family to start enjoying the benefits of a tankless hot water heater and the significant energy savings that a quality tankless water heater can offer in your Phoenix home. Allegiance Water Services’ professionals will provide you with the advice, excellent service, and quality workmanship for your tankless water heater installation. Call us today to start enjoying the benefits of endless hot water.

Allegiance Water Services sent a repair man to fix a broken sprinkler head.. He was courteous, pleasant and well informed. He fixed the head and checked to be sure the whole system was working again correctly. I appreciated his service. Thank you

I had an exceptional experience with Allegiance today. My old gas water heater needs to be replaced. I called Allegiance yesterday and discussed with David who is very knowledgeable, transparent and told me pros and cons among the different water heaters. I decided to go with 50 gallon Bradford White water heater. Ruben came in next day and clearly explained to me what is the process. He is excellent, very skillful and told me how to maintain it. He cleaned everything afterwards. I am very happy with their services and will call Allegiance for my plumbing issues for sure. Ruben from Allegiance Water Services did an excellent job again today. I had water hammer issue for a couple of months and my pipes coming out the main pipe weren't connected right by a previous plumber. The irrigation system controller needs to be replaced as well And it is now upgraded to an enabling phone control unit. Ruben did an excellent job on replacing the unit and repiping everything. It only took him an hour and they work great! Ruben is very experienced, knowledgeable and efficient. It wouldn't go wrong for Ruben to do your plumbing jobs.

John was on time and professional. He fixed the leak in my backyard system and tested it to make sure no further leaks. He also checked the front yard and found an additional leak that I hadn’t noticed and also fixed it in the same trip. Super happy with the great service and will definitely call these guys again for future plumbing repairs outdoors and indoor.

I have used Allegiance for years now and every time I'm still amazed at how courteous and professional they are. Every year I have my R.O. filter changed and my soft water big blue filter changed. They also perform my mist services for the backyard with shutdown for the winter and startup in the spring. 100% recommend them!

Why should you hire Allegiance? Quality. Dependability. Customer service. Experience. Dedication. Hard work. This company takes quality experience and service to the next level. I haven’t worked with many home service companies who do such a good job like this. From the moment we got the quote, until the minute the job was done, they were reliable and they provided the service we requested. First they came out to inspect the issue. Once they figured out what was wrong, they provided a verbal quote and followed up with a digital quote. I was able to accept the quote digitally and put a deposit down to begin the work. Since our system needed to be replaced, it was quite a process and luckily they had it all under control. They contacted the city and cox communications to flag their underground items so that they knew where to avoid. Then Lawson came out and literally spent an entire day replacing the system. The customer service was above and beyond. Yes there are a million plumbers and irrigation companies out there, but there aren’t as many reputable, trustworthy, licensed and qualified ones like Allegience.

Allegiance Water Services are prompt, thorough, and professional. I found them when they did work on my next door neighbor’s irrigation system. When my irrigation started leaking and watering weeds, I called Allegiance Water Systems for a quote and then to schedule repairs. They send text messages and emails with links to track your technician or to call them direct. Invoicing is quick and easy to access via their billing system. You have everything in writing with links to confirm, deny, or modify your service needs.

Allegiance’s technician Eloy Garcia arrived promptly, explained and showed me the issue with my water softener and also he noted some water in tray beneath the water heater that I had even noticed. He fixed the motor on softener and then removed and replaced my water heater as he noted it was still under manufacturer’s warranty! I am so please with his prompt, thorough and efficient service. I highly recommend him and Allegiance Eater Services!

I had made an appointment for Thursday, but was pleasantly surprised to receive a call on Wednesday that Eloy could come out a day early. They serviced my RO water system and soft water system. They exhibited excellent attention to detail and worked in a professional manner. When finished they cleared explained what we needed to to do move for the coming year. I will certainly use them again for annual inspections and servicing.
