Proper water heater function is essential. Without it, a home's overall efficiency suffers. When we don't have much water pressure, for example, the task of heating the water takes up more of our energy resources over the course of a day. The same principle applies to the different ways we might encounter our water not being up to proper performance standards—by which I mean, in a way that corresponds to the kind of warm, not-scalding or icy-cold water one expects from a water heater.
Specific types of water heaters, including tankless, traditional storage tank, and solar water heating systems, may encounter specialized problems that require unique remedies. Tankless water heaters, for instance, may experience decreased heating efficiency due to mineral buildup in the heating elements. The traditional tank water heater, on the other hand, may produce rusty water due to corrosion going on inside the tank. And while each type of water heating system presents its own set of challenges, it's important to know that the kind of setup you have makes a difference in what problems can occur. That why when you call for water heater repair service, the first question they ask usually concerns the type of water heater you have. Water heater repairs are not one-size-fits-all, and it pays (in cash and safety) to have the right kind of expert do the work.
Your investment is protected, and the potential need for future repairs is minimized when you conduct routine maintenance on your water heater. Of course, this is most necessary when your heater is nearing its warranty's end, but just like your car, it benefits from regular checks. And just like your car, it has parts that wear out. One of the key components that prevent your water heater from descending into the maelstrom of the murky underbelly of potential plumbing disasters is the anode rod—essentially a sacrificial part. When you check your anode rod, you're checking your water heater's health and asking the important question: "How much longer can my water heater hold out before it needs to be repaired or replaced?"
