Tank or Tankless Water Heater?
If you are looking for a new water heater, it may be tricky to determine which type is best for your home. Water heaters can either come with a holding tank or be tankless. Each one is designed for specific homes in mind. Most homes with large families use a water heater with a storage tank. These water heaters hold a large amount of hot water, between 20 and 55 gallons.
This allows you to have more hot water for a longer period of time, and you have access to more hot water at once. It’s the best choice if you want to run multiple faucets and/or showers at the same time. A storage tank water heater is rated not only by the amount of hot water it can hold, but by the FHR, or first hour rating. Your energy costs will be slightly higher with a storage tank water heater, but you won’t have to worry about multiple bathrooms being used at once.
Tankless water heaters are the most energy-efficient design. These water heaters heat the water on demand, so it doesn’t waste energy keeping water hot. However, most electric tankless water heaters only have a gallon per minute, or GPM, rating of 3.5 or lower. This means you’ll only be able to use one appliance or faucet at a time.
How We Reviewed
Each electric water heater was chosen based on customer reviews, professional ratings and best-selling lists. There are a range of prices and options available, so consider your own needs before choosing the best electric water heater.
There are an incredible variety of electric water heaters on the market, so it can be difficult to narrow down a price range. Inexpensive water heaters provide a single faucet with on-demand hot water. They are cost-effective and energy-efficient, but aren’t convenient for your whole house, particularly large families. Premium water heaters combine energy efficiency with a large storage tank. These water heaters not only keep a high volume of water hot and ready to use, they also replenish the storage tank quickly. A high-quality water heater can provide constant hot water for long, hot showers and multiple appliances.
