Top 3 Pros and Cons of a Tankless Water Heater

Tank water heaters have been the traditional source for hot water in most homes for decades. Whether they use gas or electricity, they offer a supply of water that is already heated and ready for use, with average-sized tanks holding 40-50 gallons of water. However, tankless water heaters are becoming more popular due to their on-demand design, energy efficiency and small space needs. Here are the top 3 pros and cons of tankless water heaters for residential use.

Pros of Tankless Water Heaters

  1. Lower energy costs. Tankless water heaters only heat the water on-demand, saving money off energy costs. Unlike tank water heaters that keep water hot 24/7, the tankless water heaters heat water as needed.
  2. Smaller unit. Since there is not a tank, these water heaters are much smaller in size. They can be hung on a wall or even put on the outside wall of a home.
  3. Less risk of water damage. If a water heater tank springs a leak, it can cause extensive water damage in a home. No tank means no risk of a tank leak.

Cons of Tankless Water Heaters

  1. Higher initial cost. Tankless water heaters tend to be higher in initial cost than their tank counterparts, but make up the difference in long-term energy savings.
  2. Slower hot water. Tank water heaters have many gallons of hot water ready to go, while tankless must heat water as needed. This can make it slower to get hot water, but the hot water will not run out like with a tank.
  3. Not well-suited for larger homes. If there are several rooms using hot water at one time in a home, a tankless water heater may have trouble keeping up with the demand. Most tankless water heaters can heat about 3.5 gallons per minute.

If you are looking for a more energy efficient hot water source that will never run out of hot water, tankless may be the way to go for your home. Talk to your local plumber about the options available in tankless water heaters.
