FAQ Tankless Water Heaters

Have you ever jumped into the shower after an exhausting day expecting the hot water to wash away your stress only to face cold water? Our water heaters are a luxury that we don’t often think about until they’re not working correctly. If yours is beyond repair, then it’s time for you to make a significant, not to mention expensive, purchase. At EJ Plumbing, we understand how big of an investment this is. We’ve created an FAQ on tankless water heaters so you can make an informed decision on your home’s next water heater.

Q: What are tankless water heaters?

A: As its name implies, these units heat water without the use of a tank and only when you need it.

Q: How do tankless water heaters work?

A: When there is a demand for hot water, cold water enters the tankless unit, where high-powered burners rapidly heat it. It then runs through a heat exchanger and is delivered to your faucet or shower in just moments.

Q: How are tankless water heaters different from traditional water heaters?

A: While a traditional water heater is continually maintaining a standby supply of water, tankless water heaters work “on demand,” making it more efficient. Additionally, when you use traditional water heaters, you deplete its tank and run out of water until more is heated.

Q: Are tankless water heaters efficient?

A: Yes! According to the Department of Energy, efficiency can be as high as 34% in homes that don’t require as much hot water. Even if your household demands more hot water, you’ll still see an increase in efficiency compared to traditional water heaters.

Q: What are the disadvantages of tankless water heaters?

A: We do want to give a disclaimer that tankless water heaters will have a higher upfront cost. Water heaters typically cost anywhere between $500-$800, while the tankless water heater will be double that price. However, these models will last you 10 years longer than their traditional counterparts. You must also remember that you will save money in the long run because of its efficiency.

Q: What are the advantages of tankless water heaters?

A: There are numerous reasons why a homeowner should choose a tankless water heater. Here are some of the many benefits:

  • Save on space with their sleek and slim design.
  • Never run out of hot water.
  • Tankless units run twice as long as traditional units.
  • Avoid the possibility of flooding from ruptured tanks.
  • Reduced electricity bill.
