"EXCELLENT CUSTOMER SERVICE Eddie visited our house the very day we called about our water heater. He came out, inspected the very tough location where the water heater is located and delivered an estimate with 3 options on the spot. We decided which direction to go and let Eddie know at which time he promptly scheduled our installation. On the day of install he arrived when he said he would, put down every type of floor protection you can imagine and proceeded the very difficult task of manipulating a 50 gallon water heater out of a small closet 10 feet up in the air. He worked with his partner to remove the old one, replumbed and installed the new one, again in a very tight space. Eddie ran all new venting to the outside, added electronic monitoring, and crawled under the house several times to make certain the drains were all functioning properly. We could not ask for better service and the attention to detail was amazing. This is our second experience with Excalibur Plumbing and they have both been wonderful experiences. Great customer service!!!!"

"Fantastic. Everyone at Cold Is On The Right, from Kari in the office to Billy in the field, is terrific. Our job was complicated: remove two conventional hot water heaters, one of which was in the attic, and replace them with a tankless system. In addition, our house had two separate water loops, which need to be merged into one. Cold Is On The Right did everything on-time and on-budget. They're professional in every way. I recommend the company unreservedly and count myself a customer for life. Jeff Bowden, Austin."

"I called on a Saturday afternoon & they were able to come out within 30 minutes and replaced my hot water heater! My home warranty company was going to make me wait a week without hot water! I was so thankful to Excalibur for giving me hot water so quickly!"

"We recently had Colin install our new water heater, and the experience was truly excellent from start to finish. He was friendly and patient, taking the time to walk us through the process and explain the new unit. What stood out most was the detail-oriented nature of the work; everything was installed perfectly. When the job was complete, the work area was meticulously cleaned up. The new water heater is working perfectly, and we are very satisfied. We would absolutely call 1-800-Plumber+Air again for any future plumbing needs."

Water Heaters FAQs, answered by experts

The good news is that most home warranty plans cover hot water heaters, regardless of whether you have a tank or a tankless model. Your hot water heater should be covered by your home warranty because it's considered an essential home appliance.

The right way to vent a gas water heater is to have a pipe directly upward or slopes upward out of the house. Because hot air naturally rises, this type of venting will efficiently ensure that all gas moves out of the house. Your system may rely on fans or blowers as well.

The lifespan of a water heater depends on its type, usage, and maintenance schedule. Traditional tank-style water heaters typically last between 8 and 12 years, though the range can be as wide as 6 to 15 years. Within this category, gas models often last 8-12 years, while electric models may last 10-15 years. In contrast, tankless water heaters have a significantly longer lifespan, often lasting up to 20 years or more. Factors like heavy usage, hard water, and sediment buildup can shorten a unit's life. To extend its lifespan, it is crucial to perform regular maintenance, such as flushing the tank annually and scheduling professional inspections. If your unit is over a decade old and shows signs of rust, leaks, strange noises, or inconsistent heating, it is likely time for a replacement.

Yes, hybrid water heaters can be noisy — noisier than traditional water heaters. The sound they produce is often compared to the hum of a dishwasher. Its noise comes from the heat pump’s fan and compressor as they work to pull in and compress the air. While it’s not totally disruptive, especially if the unit is installed in less frequented areas, like a basement or garage, it’s something to keep in mind if you’re sensitive to noise or if the unit will be placed near bedrooms or living spaces.

Most standard residential water heaters, which are typically around 40 gallons and use 240 volts and between 3,500 and 5,500 watts, require a 30-amp, two-pole circuit breaker. For smaller, point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts, a 30-amp breaker is also often adequate. However, some models may have different needs; units that use more watts than average may require a 40-amp breaker, while smaller units might only need a 20-amp breaker. Newer, tankless, or more energy-efficient models can also require a higher amperage. Having the correct breaker size is crucial for safe and efficient operation, so it's best to consult a licensed electrician to determine the specific needs of your water heater.
