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.

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!

After 5 years we had water softener , we found out we use soft water for our pool and watering the plants in our back yard , so I called this company they responded fast and the next day they sent their technician Ruben . After we agreed on his estimate , he came the next day. He did awesome job on separating our soft water. Ruben was knowledgeable, fast and reliable. I am so happy with his work and recommend him and this company to everyone.

Lawson installed a reverse osmosis system at our new home today. While he was here, he also helped answer (many!) other questions and helped inspect the home’s irrigation system for me. He was thorough, professional, friendly, and patient. Thanks so much Lawson and Allegiance!

I have used Allegiance Water since 2018. The company and service is outstanding. John Gonzales was our repair person for this call. He changed our RO water filters, installed a leak detector for the RO, and repaired our water shut off valve. He was GREAT!!! He is very knowledgeable and dependable. I highly recommend Allegiance and their team. Thanks

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.

Paul came today to check my Rain Bird system controller. I have worked with him during my new irrigation installation project at the beginning of this year. I was extremely pleased with the outcome then and again today. I specifically requested him for today’s job. As always, he offered excellent, professional service, knowledgeable, courteous and friendly. I would refer him and Allegiance Water Service to my friends with high remarks.

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.
