Hot water is essential to your comfort, especially if you live in colder areas. A nice hot shower or rinse of your face in the morning can help you relax. With all the different water tanks on the market, it can be hard to distinguish between the different types and features. Water tanks can make up a large percentage of your bills so it is important to choose the best one to fit your needs. Most people overlook the importance of choosing a quality water heater since it can get a bit complicated. In this guide we help to break down some of the nitty-gritty details to wash away some of the confusion.

Things to Consider Before Buying

Size and Capacity

The size and capacity of the water tank are important to consider. There are ones that can equip your whole home and others that are more suitable for individual faucet use. Typical tank water heaters have a wide range, anywhere from 4 gallons to over 100 gallons. This usually depends on how many people live in the home and how much water is used.

First-Hour Rating

This rating is the number of gallons the heater can deliver in one hour. There are tools to help you calculate this depending on the size of your home. It also helps to save energy and money over time. This rating is essentially the tank’s efficiency.

Fit

Remember, you need to be able to install your water heater so it is important to check the size of the new water heater you want to buy since it will not always fit in the same spot. Since water heaters do not need to be replaced that often; when it comes time to change it, there are new models. Companies are making changes to efficiency and insulation, which may change the sizing.

Additionally, if you are replacing a tankless water heater with a storage tank-type water heater, there is going to be a large change in space requirements.

Types

Gas vs. Electric

This refers to how the water heater is powered. It usually depends on what type your home offers. You can opt to switch the type; however, the installation to switch water heater types can run up to over $1000. In most cases, people just choose to go with whichever their home offers. To help you decide which one is best for you, we break down the two different types.

Gas water heaters use natural gas, and when the water starts to heat up, it rises to the top and comes out of the faucet. Electric water heaters are the same, except it uses electricity to heat up. In the United States, electricity usually costs more than natural gas, so this is important to consider. Gas water heaters usually have a higher upfront cost and can also be hard to install by yourself. It is important to note that electricity goes out more often than gas would. This means that your hot water could be interrupted if the electricity goes out. The dangers of the gas alternative are water heater explosions, but in this day and age, it is very unlikely to occur. Both gas and electric water heaters are rated by the amount of power used to heat the water in the tank.

Point-of-Use Electric Mini-Tank Water Heaters

This is a type of water heater that is used for single applications such as a sink, extra rooms, or even small apartments. The hot water is usually located near the faucet, so the most important factors are the flow rate and tank size. The small tank heats the water to a set temperature until you are ready to use it. Note that these have a limited capacity and should not be used in large quantities. They also work much quicker than traditional water heaters since the tank is small and heats up quickly. They typically range anywhere from 2-7 gallons.

Features to Look Out For

  • Warranty- Water heaters are not cheap, so you want to look for one with a quality warranty program. The last thing you want is for your tank to start leaking, and you need to purchase a brand new one. The longest warranty is best, but these are often a bit pricier.
  • Brass vs. Plastic Valves- Higher quality valves are more durable and require less maintenance and replacing. Plastic valves help to reduce the price of the unit, but they break much more easily.
  • Safety- Especially if you choose a gas water heater, the safety of the product is important. If not, there are risks of a gas leak, and lead to a serious accident. Many water heaters come with improved safety functions so be sure to look out for these.
  • Energy Efficient- This is essential in keeping your bills down. High energy-efficient heaters use less energy and are available for gas models. Typical higher-priced units will give you better efficiency.
