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.

David was terrific to work with to get my endless questions answered and align on the right water softener system. Lawson, who installed the water softener was outstanding. He explained service and care issues and did a very professional install. The whole team takes their customers satisfaction seriously. I'll be back for future plumbing needs!

Had an issue with my sprinkler system, something failed and I had a big wet spot on the side of my house. Called in and was helped with instructions on how to turn off the sprinkler side so no water would go to it until a repair could be scheduled. Paul comes out and shows me the problem, we set a time and he fixes all of that, THEN while testing, just waltzes into the spraying sprinklers and dials in where the water SHOULD have been spraying, like " oh, that's the wrong direction to spray for this area..." Then he programs the whole thing to fix my already mediocre lawn and bushes, told me what to do to improve my lawn through yard care and got into his car with soaking pants and thanked ME! 10/10.

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 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!

I love this business. They go the extra mile to make sure their clientele are taken care of. My hot water heater went out on New Years eve and required a part to fix it. The part was unavailable and Rheem the manufacturer was closed until Monday. John Gonzales from Allegient brought out a new unit and installed it, so that I would have hot water for the weekend. This is a great company, and I am glad that I selected them. UPDATE Allegiance is my go to water company. My house is 50 years old now, so I'm glad I have them to call if I have a problem. Rommel Valenzuela came today to service my filtration system. He was nice, professional and did a great job.

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.
