Tank vs. Tankless Heaters

Here are the differences between tank and tankless water heaters, so you know which option is best for your home and family.

Tank heaters offer:

  • Lower initial costs
  • Less maintenance & repairs
  • 10–15 year lifespan
  • Higher utility bills
  • A larger footprint
  • Lower efficiency

Tank heaters can run on natural gas or electricity and hold 30-50 gallons of water. However, every time you need hot water, your system must heat all 30 gallons of water before it can reach your sink. They have a shorter lifespan and higher monthly bills than tankless versions while taking up significant storage space that you could use.

Tankless heaters are:

  • Cheaper to operate
  • Last 20-30 years
  • Require less space
  • Higher efficiency
  • High initial cost

Tankless heaters may have a higher initial cost if you don’t already have a gas line for your heater, but they only take up the same space as a shoebox or small carry-on. With cheaper operation and higher efficiency, you can get hot water in as little as 15 seconds while saving money on your monthly utility bills. These heaters also last twice as long as their tank version while clearing space that you may need.

Do Tankless Water Heaters Require Maintenance?


Although tankless water heaters require less maintenance than traditional tank-based water heaters, they are not completely maintenance-free. Regular maintenance of your tankless water heater can help prevent costly repairs and extend its lifespan significantly. Some of the most important tasks to carry out when maintaining a tankless water heater include flushing the unit regularly to remove sediment buildup, inspecting all connections for leaks, and replacing the air filter and spark plug yearly. Additionally, it is important to check for any corrosion or rust around the unit and have any major repairs handled promptly by a professional. Following these simple steps can help ensure that your tankless water heater will provide you with safe, efficient hot water for years to come.

Types of Tankless Heaters

Your heater will provide hot water, whether it’s electric or gas. However, depending on your family size and home setup, one power source may better suit your family. Electric water heaters have a low initial cost and easy installation because every home already has an electrical system. These are typically safer than gas heaters because there’s no open flame and come in a wide range of sizes to match your home’s needs. However, you have a higher monthly cost, slightly slower heating times, and a loss of hot water during power outages.

Gas heaters offer efficient hot water, a lower monthly cost, and operate during power failures. This is a beneficial option if you are replacing a gas heater. If your home doesn’t already have a gas line, you may have a higher installation cost. Occasionally a gas heater may need to be relit, so the open flame is more dangerous and has a shorter lifespan than its electrical counterpart. Don’t deal with a tank heater with limited efficiency and wasteful practices when you can trust Adams HVAC & Plumbing for tankless water heaters in Mt. Juliet.
