How many years before a water heater needs to be replaced? What are the tell-tale signs? We answer these questions and more, now!
We wish we could give an exact answer to this question, but there is a pretty wide time range! The average water heater lasts between 6 and 13 years. If your water heater is 8 to 10 years old, we typically tell people to start looking for a replacement. Because it’s easier to replace an old but working water heater, than to deal with a water heater that’s started to produce rusty water, or gurgling noises, or has started to leak!

Along those lines, we’d like to quickly run down the signs and symptoms of a failing water heater. If you notice any of these things, call Parker & Sons right away!

Here at Parker & Sons, we also offer tankless water heaters. Up until this point in the blog, we’ve been talking about traditional tank water heaters, because that’s the type most people own, and the reason these only lasts from 6 to 13 years is because of how they operate:
At the bottom of the tank, a burner or element heats up your water, which is great … but the with having a tank of standing hot water is that the tank will eventually start to corrode. Water heater manufacturers do have something in place to prevent this, called an “anode rod,” which draws corrosive particles to it like a magnet. This prevents corrosion from eating away at the bottom of the water tank. However, eventually, this anode rod collects so many corrosive particles that it can’t collect any more, at which point the corrosive particles, like sharks, seek to eat away at the bottom of your water heater.
This doesn’t happen with a tankless water heater. This type heats up water immediately when you need it and doesn’t store the hot water. The system still eventually gets corroded, but it takes about 20 years. Another reason a lot of people like tankless water heaters is because of the on-demand hot water – bringing you hot water in about 15 seconds, as opposed to a minute or two!
