4 Pros and Cons of Tankless Water Heaters

Everyone likes the idea of a smaller tankless water heater because they take up less space and unlimited water. What can be bad about a tankless water heater? The tankless water heater works because of the heater exchanger (heat exchanger is a device that transfers heat from one source to another).  You have to size the tankless water heater properly by the amount of fixtures you have in your home. If you don’t the temperature will not get as hot as needed. Some bigger homes need two or three units to keep up with the demand. Here are some pros and cons for tankless water heaters:

  • Pros 
  1. They take up less space
  2. Very energy efficient
  3. Unlimited amount of hot water
  4. No storage of hot water
  • Cons 
  1. Electric Tankless heaters need bigger breakers so you would need to hire an electrician to install.
  2. Gas tankless water heaters require modifying the vent and gas lines
  3. if you don’t have a water softener the hard water affects the heat exchanger causing hard water deposits and eventually causing the water pressure to be very low on the hot side so you need to maintain them every few years by hiring an Deltona plumber to do a flush on the unit.
  4. They are usually 3 times the cost of a tank heater.

Overall you need to look at your situation and decide on what is the best fit for your household. Gas tankless seem to have less plumbing problems where electric units have a little more problems. But either way you decide, make sure you choose a well known brand so if you have any problems they will stand by the unit.
