What You Need to Know About Water Heaters

In a true example of planned obsolescence, did you know that standard tank-style electric or gas water heaters start to leak and fail within 8-12 years? That makes water heater replacements one of the most common home improvement projects. Although there may be warning signs when they are starting to fail, the most important factor to consider is the age of the heater, because in most cases, the tank will fail without any warning signs.

One of the most important things to consider is what areas would be affected if your water heater started leaking. If it’s located in an unfinished basement near a sump pump, that would be considered a lower degree of risk if the tank failed. If the heater tank is in a finished basement or a part of the home where a water leak could mean extensive damage, it’s best to replace it based on age. Also, if the water runs lukewarm or cold, or if you see rust and corrosion on the tank or piping, consider replacement.

Leak detection devices have become more and more popular, and now you have the option to have the water heater set in a pan that automatically shuts off the water to the unit if water is detected in the pan.

When water gets heated, it expands. There’s often nowhere for the expansion to go, so it builds up pressure in the plumbing system, and can cause the temperature and pressure relief valve to drip or blow off. This causes unnecessary stress to the water heater and the entire plumbing system. So, part of the current plumbing code requires that new water heater installations include a thermal expansion tank.

When purchasing a new hot water heater, it’s important to look at how your current hot water needs may have changed. For instance, if more or fewer people live in the home, the tank size that you need may have changed. Water heaters come in a few different sizes, so consider your usage requirements before simply replacing the water heater with the same size that was there.

Efficiency is paramount when you consider that about 25% of the energy in your home goes toward heating your water. Tankless water heaters are one of the more efficient options available. They can last 15 to 20 years. They also save on space. They do require annual service and flushing, but being vigilant about the upkeep will increase the life expectancy of the unit.
