How To Know If Water Heater Replacement May Be Necessary

By Karina Frost


Because they are hidden in basements or concealed in closets, water heaters are usually taken for granted. Depending on the regularity of maintenance and design characteristics, they last around ten years, and may cause few noticeable problems until the shower suddenly turns frigid. Knowing the signs that water heater replacement may be needed saves homeowners money, time, and mental strain.

Unless a homeowner enjoys do-it-yourself projects, the unit often escapes inspection. One obvious sign of trouble includes a wet buildup or visible leakage around the base. This can be a serious issue, because a leaking unit has the ability to cause an expensive flood if it gives out completely. If hard-to-ignore moisture is routinely appearing around the heater, shut it down immediately.

If there is no need to turn on the cold tap when showering, the heating unit is probably functioning at low capacity. When this issue is not logically related to higher-than-normal use patterns, it can be a result of malfunctioning internal heating elements or connections, which mainly affect homes that rely solely on electric power. Units that usually recover quickly may simply be too small for the number of users.

It can be startling to find a thick layer of sediment at the bottom of a tank, but not unusual. Over time, microscopic soil fragments settle, eventually degrading the metal floor, and are a common cause of overheating. The issue can be avoided by yearly flushing, but if that has not occurred for a long period, it may be necessary to have it done professionally.

Other common symptoms can be heard in the form of strange rumblings, clicking, or high-frequency whining sounds. While difficult to accurately pinpoint, the noises are a good indicator of the need for maintenance, and may foretell failure. The noises are also usually the result of a buildup of sediments, and a thorough flushing may help. In many cases, the tank has come to end of its useful lifespan.

Replacement can be a very good plan even when there are no visible signs of problems. The key is in the average monthly energy bill. Different regions rely on various power sources, and none are inexpensive today. Older units may still be functional, but use far more energy than is necessary. Installing a modern, energy-efficient model saves money and helps the environment.

One alternative is the tankless heater, designed to eliminate traditional storage. Instead of being kept inside a tank, water is heated directly as it passes through, and can provide a flow up to five gallons each minute. That amount may not adequately serve a large household, but without the tank, more than one unit can easily and economically be installed, creating enough capacity.

Some residents of White Hall MD replace their own units, but many homeowners find the prospect daunting. While a new appliance theoretically should fit the old connections, threading them can require knowledge of soldering or solvent welding. Those lacking the tools, time, and patience to do it themselves usually call a local plumbing and heating expert, who can do the job quickly and efficiently.
