What you need to know about water heaters

Is your water heater acting up? It might be time to replace it! That is, of course, if it’s still working at all. If you’re unsure about whether or not it’s time to replace your water heater yet, read this article for some advice on how to tell if you need a new one and what type would be best for your home.

What is a water heater?

A water heater is a device that heats up water for use in homes. It heats the cold water to the desired temperature, conserving energy and eliminating cold showers. The most common type of heater is called an electric resistance or tankless heater. These heaters are always on and require less energy than other types of heaters.


There are a few types of water heaters that you should be familiar with. The first is a tankless, also known as on-demand. This type works by heating water as it’s needed rather than storing it in a tank for future use. They’re more expensive, but they save you money in the long run because they use less energy and make cleaning easier.

Reduced flow is another type of water heater. These work by only heating the amount of water that is needed at any given time, which can save you money on your utility bills.

Water Heaters and Hot Water Heaters – Which One is Best for You?

Knowing the difference between a water heater and a hot water heater is essential if you want to make sure you’re getting exactly what you need. Water heaters are a great investment. Hot water heaters are the best way to go if you have not already invested in a tankless water heater. Hot water heaters offer many benefits compared to traditional tank-style heaters, such as:

High Efficiency: Tank-style hot-water heaters typically waste over half of the energy they use to heat the water because of wasted energy through evaporation and condensation. This is why high efficiency gas and electric water heaters are so popular among households.

Energy Efficient: Gas hot water tanks don’t work well in areas with high humidity like bathrooms, garages or laundry rooms because when it gets humid, the moisture in the air can cause corrosion on the sides
A hot water heater works differently. Rather than heating up your water like a typical heater, these devices work by storing heated water for later use – meaning that you don’t have to reheat.

Common issues

Common water heater issues include: Leaking tanks, leaking pipes, pump failure, and broken or missing filters. One of the most common problems is a leaky supply line pipe that delivers hot water to the tank. The supply line should be connected as close as possible to the water heater’s inlet valve. This decreases the distance between hot and cold water lines before they reach your shower head or faucet and prevents pipe leaks from occurring inside your line.

  1. Your water heater should be installed in a location that allows for proper ventilation and easy access to the thermostat. In other words, don’t put it in a crawl space or attic attic. That just creates trouble down the road when you need to service the unit or replace it with a larger model.
  2. Water heaters are not used at optimal efficiency in most homes because they are installed above waist-height, leading to partial fill ups during the day with hot water followed by lower profit margins at night when these units chill down overnight in many cases.
  3. The point of a water heater is to keep your house warm so that you can sleep comfortably at night, not so that you can have warm baths

How do you know when a hot water heater needs to be replaced?

A hot water heater should be replaced every 10-15 years, depending on the model. If you’re not sure how to tell if your heater needs replaced, start by checking the temperature of the unit. If it’s not producing enough hot water for your household, then it’s likely that it needs replaced.

If you suspect that your hot water heater is on its last legs, then you need to get a second opinion. The most obvious sign to look for is if the pressure relief valve (PRV) has moved or gone dry. If the PRV is still in place and there are no leaks coming out of it, then your water heater is probably fine.

An additional sign is sediment buildup in the tank, which can cause corrosion in the heating element. When this happens, one part of the tank can become too hot while another remains cold.

Do you need a professional to replace a water heater?

If it is still under warranty, the manufacturer may replace the water heater for free. If it is not under warranty, you should have a plumber come to your home and provide an estimate on cost. Some homeowners choose to do the work themselves, but be sure that you are qualified to do this before attempting it or it can result in expensive problems. You will need to purchase new parts beforehand and use your old water heater as a donor for these parts if possible.

Sources of leaks and other problems

Leaks are one of the most common issues with residential water heaters. Some leaks can be found by just looking at the unit, while others might require listening for the sound of running water. If you detect a leak, do not ignore it because it could lead to expensive repairs or replacement. Also, check your pilot light frequently to ensure that it is lit and functioning correctly. Other problems that may occur include inadequate combustion or insufficient insulation.

How should I maintain and care for my water heater?

Water heaters should be properly maintained to ensure their longevity. The main thing is to check the back and sides of your water heater for any leaks. If you notice any, have it checked out immediately. Old water heaters can rust and develop leaks, so they need to be replaced when they start emitting a foul smell or rattling noises.

Once you have your water heater in good working condition, make sure you maintain it by regularly cleaning it and replacing the filter on it. Also make sure that the thermostat is set at 90°F (32°C) or higher; this will help keep the water warm enough to run cool-to-hot tap water through showers without wasting energy.

Efficiency is the key

There are many factors to take into consideration when considering a water heater. Efficiency is one of the most important because it could save you a lot on your monthly energy bill. Another factor to consider is the warranty, which should be at least 10 years long.
