"Our tank water heater went out. Since it was 14 years old, we decided to get a new tankless water heater. USA Water Heaters was very responsive when we requested a quote. We received a couple other quotes, and they were pretty similar in price. We went with USA Water Heaters because they were the only company that told me about the rebates offered by the gas company. They provided all required documentation, without my even having to ask for it. The others were not even sure there were any rebates available. USA Water Heaters arrived on time, completed the job in the time they promised, and did a great job of cleaning up when the job was complete. They were very professional. I would definitely use USA Water Heaters again definitely would recommend them to anyone that needs a new water heater."

"We had our water heater replaced by The Water Heater Company and the service was excellent from start to finish. The technician, Mike P., was professional, on time, and extremely knowledgeable. He explained everything clearly, completed the installation efficiently, and made sure the area was clean before leaving. My new water heater is working great. We really appreciate the quality of work and the attention to detail. We highly recommend The Water Heater Company especially if you want a smooth, stress-free water heater replacement done right the first time."

"I called Ca-Tech on a Saturday morning to check my water heater, and I was impressed that they were able to come later that morning. Albert arrived when he said he would and was very personable and very professional. He gave me a quote for a repair and also to replace my water heater. I choose to replace the water heater. When Albert returned later that week, he came on time and was very professional with the way he did the work. I liked that he kept me informed. I will definitely call Cal-Tech Pluming again."

Water Heaters questions, answered by experts

The time it takes to install or replace a water heater depends on the type of heater and the complexity of the job. A professional can typically replace a standard tank-style water heater in one to three hours. However, if the work area is tight, such as a small closet or crawl space, the job could take four to five hours. Replacing an existing tankless unit takes about two to three hours, while upgrading from a tank-style to a tankless water heater is more complex and can take four to six hours. The project will take longer if you are switching fuel sources, such as installing a gas heater which can add about an hour to the timeline, or if the unit needs to be relocated.

Yes, you can replace a current tank water heater with a tankless model or vice versa. If you’re maintaining the same fuel source—gas or electricity—the switchover should be smooth. A conventional tank requires open floor space, while a tankless model can be wall-mounted. If you’re switching to a tank water heater, you might need to clear space for it. Gas-powered tankless water heaters need a large volume of gas when they start running to heat the water instantly. You might need to increase the size of the gas line when going from a tank to a tankless model.

Often, the first issue you might encounter is a lack or loss of power—this could be caused by a tripped switch or a failed heating element. If your hot water is not producing enough power and its size is not the issue, you might need to replace one of its heating elements. A leaking water heater could be caused by tank erosion.

A tankless water heater can last up to 20 years, which is nearly double the lifespan of a conventional tank heater. However, their longevity is highly dependent on several factors. With proper installation and regular maintenance, such as descaling to prevent mineral buildup from hard water, you can expect a lifespan of 15 to 20 years. Without proper care, a tankless unit may begin to fail in as little as 12 years. Other factors that affect its lifespan include household usage and the quality of the local water supply. While they have a higher upfront cost, their energy savings, smaller size, and longer life make them a worthwhile investment for many homeowners.

Several signs indicate your water heater may be failing or in need of replacement. Key indicators include:

  • Age: A water heater older than ten years is approaching the end of its typical lifespan.

  • Water Quality: If you notice rusty or discolored water from your hot water faucets, or a foul odor similar to rotten eggs or sulfur, it can signal internal corrosion.

  • Unusual Noises: Banging, rumbling, or popping sounds from the tank often mean sediment has built up, causing the unit to overheat.

  • Leaks: Any water pooling around the base of the tank or visible leaks are clear signs of failure.

  • Performance Issues: A decline in performance, such as water not getting hot enough, taking longer to heat up, low water pressure, or decreased efficiency, suggests the unit is struggling.

  • Visible Damage: Obvious rust and corrosion on the exterior of the tank can indicate a more serious internal problem.

While these signs often point to replacement, some issues may be fixable. It's best to consult a professional plumber to diagnose the problem before investing in a new unit.
