"Water Heater Masters were top-notch! I called on a Saturday afternoon - they were available 9am Sunday morning to come and inspect and quote. They only had one guy working that day, but scheduled me for Monday morning between 8 and 9. At 8:15am I got a call with an ETA of 8:45, which was a really nice touch! Despite telling me it would take an entire day to install, they were done by 1pm. They also found some creative ways to do the install to avoid drilling through my stucco (for the exhaust vent and for the condensate run-off). Very professional and clean-looking install. These guys may not always be the cheapest around, and they recommended a top-of-the-line heater (which is what I really wanted anyway), but I'd much rather pay a little extra for that level of service and support. Thank you!"

"Call in the morning, visit that afternoon with quote, installation next day. They didn't have our model in stock, so we got an upgrade to the next larger water heater at no additional cost. Installer was very knowledgable and friendly."

"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"Excellent co-ordination by the office. Lady set up a visit by her field worker - he showed up on time to evaluate the problem. He needed a gasket to fix the problem but had to get one at a supply store. Because he took longer to return then planned, he reduced the price by $30 and threw in a water pressure check as well. Oh, the gasket did fix the leak. Excellent job by all concerned."

"Aaron and his crew were quick to respond. Within an hour of awarding the job to Aaron, his crew was at our home removing the old water heater and preparing the site to receive the new water heater. Within another hour, Aaron arrived with the new water heater and it was installed. We hired him on the spot for another project that he completed on the next work day. I will be keeping his number handy for any other projects that we need to have done."

Water Heaters questions, answered by experts

A well-maintained hot water recirculating pump can last 5 to 15 years. Pumps that run continuously may have a shorter lifespan than demand-controlled models. Hard water can reduce longevity by causing mineral buildup in the pump and pipes. Regular maintenance, such as cleaning or replacing filters, can extend the pump’s lifespan.

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.

Excessive pressure (above 80 psi) puts too much stress on plumbing pipes, joints, and fixtures. This can lead to leaks and burst pipes. Plus, it shortens the lifespan of appliances, can waste water, and can raise your utility bills. High water pressure might feel like a gift, but it’s actually a silent threat to plumbing.

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.

If your water heater is about to celebrate the big 2-0, you may want to consider sending it off to greener pastures. While the water heater may seem to be working well, any conventional, tanked water heater over 10 years of age is at risk of failure. If your water heater is 20 years or older, your best move is to replace your aging heater before it completely breaks down.
