Tankless vs Tank Water Heaters — The Pros & Cons

Tankless vs Tank Water Heaters -- The Pros & Cons

A new water heater for your home is a substantial investment and choosing the right one is a decision you will live with for years. Whether you are replacing an old water heater or choosing what to install in a new home, knowing your options is an important first step. Start by determining which type of water heater is best for your situation: tank (storage) or tankless (on demand).  Each offers benefits and trade-offs. The main considerations are cost, efficiency and longevity.

As the name implies, tank water heaters work by storing water (typically 30-50 gallons) in an insulated tank and heating it continually so it is ready when you turn on the faucet. As the water is used, fresh water refills the tank and is heated.

Tankless water heaters do not store water. Instead, when needed, high-powered burners heat the water as it passes through a heat exchanger on its way to the faucet.

Here’s how both types of water heater measure up.

A tankless water heater is significantly more expensive to purchase initially, both for the unit itself and for the installation, particularly if you are replacing a traditional water heater with a tankless system. However, a tankless system will cost less over time, both in lower energy costs and replacement costs. Tankless water heaters can last twice as long as a water heater with a tank.

Tankless water heaters are more energy efficient because instead of continuously heating a large amount of water (whether it is used or not), the tankless system only heats the water as needed. How efficient the water heater is varies based on the amount of water used. For less than 41 gallons per day tankless systems are 24-34% more efficient than tanks. That percentage drops with more water used, but efficiency still remains greater for tankless water heaters. Homes that use natural gas will save more over those that use electricity to heat water.

Other considerations:

  • Tankless water heaters take up less space than a tank heater, which may be a consideration in new construction or if you are looking to remodel.
  • With a tankless system, there is no waiting for hot water. Less water is wasted because you don’t need it to run until it heats up.
  • Tankless heaters have difficulty heating water for multiple uses at once, such as two people taking simultaneous showers or using the dishwasher and the washing machine at the same time. However, an inadequately sized water tank can also result in hot water running out after several showers or other uses.
  • Storage tank systems are simpler and repairs are less costly.

A Few Good Reasons to Consider a Tankless Water Heater

Categories: Tags:

It’s been a long day, and all you want is to take a hot shower and go to sleep. You step into the bathroom, turn on the faucet, and wait a minute for the hot water to start flowing. But it doesn’t. All you get is cold water.

This is not a desirable scenario. But many people have experienced a time in which their water heater stopped functioning properly. If your water heater does not seem to be working well, and you think it’s time to contact a water heater repair company, do a bit of research before you pay for repairs. Now might be a good time to consider a tankless water heater.

A water heater without a tank does not utilize a storage tank. Instead, water is heated on-demand. There are several benefits to this type of water heating system. Besides providing a home (or any building) with a constant supply of hot water, a tankless water heating system has several other benefits. For more information about water heaters and the pros and cons of a system that requires a tank vs. a tankless system, give Rheem Pro Partner a call. We are a Denver water heater repair company that has extensive experience with all types of water heaters, and we are here to answer all of your questions.

Here are some of the reasons to consider a water heater without a tank:

It’s energy efficiency. A tankless heater does not require a storage tank. When a tank is used to store hot water, it must keep the water hot all hours of the day – so that it’s hot anytime a person turns on the hot water faucet. Since a tankless water heating system heats water on demand, there is no need to keep water hot in a tank 24 hours a day.

It’s small. Compared to the size of a water heater with a tank, a water heating system without a tank is small. If you live in a small home or condominium, you might not have room for a large water heater with a tank. In this situation, a tankless system is a perfect alternative. Additionally, a tankless system allows you to have more storage space available in your utility room.

It’s reliable. While every appliance needs maintenance and service every so often, a water heating system without a tank is typically very reliable. Unlike a water heating system that requires a tank, a tankless system will not rust. A water heater with a tank might last 10 or 15 years, but a tankless system can last longer. Due to its durability, you might never need emergency water heater repair when you have a tankless system!

It’s more expensive. While a tankless water heater might be more expensive to purchase than a water heater with a tank, you might realize a significant savings on your monthly energy bill. The savings each month should add up, and eventually make the cost of a tankless water heating system worthwhile.

Eliminate the need for emergency water heater repair with a tankless hot water heating system. Many people have questions about how this type of system works, when compared to a traditional water heater with a tank.
