Tankless Water Heater Vs. Tank Water Heater

Debating which water heater is best for your home? There are a few key factors to take into consideration:

  1. How much water do you use each day?
  2. Does your home have a gas line?
  3. What is your current budget for a water heater?

A traditional water heater will hold a typical day’s worth of water (30-50 gallons). It’s significantly cheaper upfront than a tankless unit. Natural gas tank water heaters are going to use around half the energy of an electric tank unit.

Tankless water heater systems are, as their name states, without a tank and take up less space. They also use a lot less energy than a conventional tank system as they only need to heat 2-3 gallons of water each time it’s in use rather than 30+ gallons of water.

Tankless systems have a more efficient design and concept, which also shows in their lifespan. So while you may be paying significantly more upfront for a tankless system, you will likely save more in the long run through monthly energy savings. You may even get an extra 5-10 years of runtime over a traditional tank system.

Ultimately, you know your home and budget better than we do. Our professionals are there just to help you understand your options and have the information you need to make the best decision for your needs.


Whether you decide to purchase a new tank or tankless water heater, it is vital that the system is set up properly to get the full benefit of this home investment.

A quality system will help give you the convenience of quick access to hot water; however, a poorly run plumbing system can create inconsistency and delays in your access to hot water. This has nothing to do with your new water heater and everything to do with how it’s able to send water to your different appliances, sinks, and faucets throughout your home. If necessary, McLay Services can repipe your home to fix any odd piping jobs from previous plumbers.

Call us today to learn more! We are happy to install any system that you feel will satisfy your home’s water heating needs. We can also help keep your water heater running at its best by providing routine maintenance services and making any necessary repairs that it may need.

A FRIENDLY, HELPFUL, AND PROFESSIONAL EXPERIENCE

Today’s experience with McLay’s was perfect. I called mid morning for help with a plumbing issue and was so happy and surprised to get a same-day appointment window from 1 to 3pm. Shortly after noon, Cesar called to say he was on the way. I was delighted that he was early, and appreciated that he followed their safety protocol. He explained everything confidently and clearly (he would make an excellent trainer). From start (my call to the office) to finish, this was a friendly, helpful, and professional experience – no surprise, as this has been the case, every time, with McLay’s. Thank you!

CAN TROUBLESHOOT ANY ISSUES

Chad is the very best service tech at Mc Clay and other better than other plumbing service tech we have used. He is nice and can troubleshoot any issues. He has come to our house and condo several times and he responds on time. He was able to fix our problem at home 3 hours after we called him on Saturday. I have to say the office staff was great as well, called us back immediately and scheduled the appointment. GREAT JOB TO ALL!!
