Tankless Water Heater Installation for Burleson, Granbury & Mansfield

Tankless water heaters have become increasingly popular due to their efficiency and ability to deliver hot water on demand, eliminating the limitations of a storage tank. Unlike traditional systems, they heat water only when needed, reducing energy waste and freeing up valuable space in your home.

Airmasters AC, Heat, Plumbing & Electrical provides professional tankless water heater installation and service throughout Cleburne and the surrounding communities. Making the switch from a conventional tank to a tankless system is a significant upgrade that requires careful planning and precise installation. Our team can assess your home’s capacity, review your hot water usage, and recommend the right size and type of tankless unit to meet your needs.

Are Upgrades Required for Tankless Systems?

Installing a tankless water heater often requires upgrades to your home's existing plumbing and electrical infrastructure. Gas tankless units require an adequate gas supply to meet their higher BTU demands, typically ranging from 150,000 to 200,000 BTUs, compared to the 30,000 to 50,000 BTUs required by standard tank water heaters. This means your existing gas line may need to be upsized to deliver sufficient fuel. Venting requirements are also different, requiring specific materials like stainless steel or PVC that meet manufacturer specifications and local building codes.

Electric tankless water heaters have significant electrical demands. Whole-house electric tankless units can require 100 to 150 amps of dedicated electrical service. Many homes lack this capacity, which means upgrading the electrical panel and installing new circuits. Point-of-use electric tankless models draw less power but still require dedicated circuits.

Water quality is another important consideration. Hard water affects tankless systems differently than tank systems. Mineral buildup occurs in the heat exchanger, and without regular descaling maintenance, efficiency drops and the unit can fail prematurely. If your home has very hard water, a water softener is strongly recommended when installing a tankless system.

Can Tankless Systems Support Your Home's Hot Water Demands?

Whether a tankless water heater can meet your household's hot water needs depends on sizing the unit correctly.

Tankless systems are rated by their flow rate, measured in gallons per minute (GPM), and their temperature rise (the difference between incoming cold water temperature and desired output temperature).

In Cleburne, groundwater temperature averages around 60 to 65 degrees. To heat water to 120 degrees for showering, you need a temperature rise of about 55 to 60 degrees. A standard shower uses about 2.5 GPM, so running two showers simultaneously requires a unit capable of delivering at least 5 GPM at a 60-degree rise. Multiple simultaneous demands (like the dishwasher, washing machine, and shower running at once) require careful calculation to avoid situations where the unit can't keep up.

Tankless units provide endless hot water as long as you stay within their flow rate capacity. If you exceed capacity, the water temperature drops. Larger homes with multiple bathrooms may need two tankless units or a larger commercial-grade unit to handle peak demand. Point-of-use tankless units offer an alternative approach, with smaller units installed near the fixtures they serve, reducing wait time and matching capacity to demand in each location.

Jacob was AMAZING! I honestly can’t thank him enough for helping us out. He actually had to come out three times to fix another company’s issue and he was so kind and helpful each time.

Courtney E.
Thank you for such a quick and fantastic job!!
I came home to a warm home on Tuesday evening. I was referred to AirMasters and gave them a call at 5:20. Shannon Holmes was out to my house by 6:30. By 7:45 our AC was fixed!! He was very honest, friendly, and professional! We signed up for them to service our system because of the professionalism that was shown to us.

Airmasters will always be my first call.
Airmasters has been great. Another air conditioning company quoted me $3500 to replace a thermal expansion valve. I called Airmasters and they determined the part was still under warranty and was able to do the job for a third of the original quote. Airmasters will always be my first call. Sam was the technician that came out. He was very professional and extremely knowledgeable.

Bryan R.
This company is an extra effort company.
In the past two years we have had a new central air system and have had our old breaker panel replaced by Airmasters. Excellent job by them both times. Everyone we came in contact with was a pleasure to deal with, especially the guys that actually did the work.

Rocco C.
Great team!
Sam was wonderful. He came to check on my heater and quickly found the problem. He was very knowledgeable and friendly. I will definitely start using Airmasters going forward and refer everyone to them. So easy to make appointments and not have to wait weeks to get an appointment. The young lady that

Excellent service!
Daniel was very efficient and easy to talk to. He explained everything he did and tried hard to make low cost repairs if possible. He seemed to have a wealth of knowledge about air conditioning systems. We would highly recommend him.

Gerald
Total professionals. Thanks again!
Troy Endtricht was my technical and I couldn't be more pleased. He took time to tell me thing about the system I did not realize. He gave me a complete rundown of the system checks he conducted. Airmasters installed this system in my new home and did a super job. Their follow up service is excellent and rapid if desired. I would use them for all your Heating and Air needs. They haven't been in this business for 35 years because they are doing something wrong.

Ken F.
Great company and ownership!!
Mr. Holmes was an excellent professional, and undoubtedly a genuine person. Attention to detail and professionalism characterized by his willingness to be accurate and thorough in his work does not go unrecognized! Request Shannon Holmes if he’s available… Great company and ownership!!

Michael F.
I’m glad they have my back.
We’ve had two issues since we moved into our new home six months ago. Both times technicians were sent out late in the evening within an hour. They were courteous and quickly diagnosed the problem on a new-to-the-market system. On the occasion it couldn’t be fixed immediately, Derek made sure I had heat until it could be taken care of. They were back the very next day to get it fixed!

Maintenance Needs for Tankless Water Heaters

Tankless water heaters require regular maintenance to perform efficiently and reach their expected 20-year lifespan. Annual descaling is necessary, especially in areas with hard water. Mineral buildup in the heat exchanger reduces efficiency and can lead to the unit failing. Descaling involves circulating a vinegar solution or commercial descaling fluid through the system to dissolve mineral deposits.

The air filter and intake screen need periodic cleaning. Tankless units draw in air for combustion, and dust and debris can clog the filter, restricting airflow and leading to incomplete combustion and reduced performance. The flame sensor and ignition system should be inspected annually, as these components can accumulate soot or fail over time, causing the unit to malfunction or fail to ignite.

Unlike tank water heaters, which often exhibit obvious signs of failure, such as leaks, tankless units may simply stop providing adequate hot water or display error codes. Regular professional maintenance catches minor issues before they become expensive repairs.
