Why Homeowners Love Tankless Water Heaters

Signs You Need To Replace Your Water Heater

Are you wondering whether you need to replace your water heater? There are a couple of signs to look out for that will help you determine whether you are better off installing a new water heater and skipping the repairs.

Signs that it's time to replace your water heater include:

  • Your water looks rusty-colored -
    Water should never come out any other color than clear. If your water is coming out of your faucet with a red tinge to it, it could be due to your water heater having rust within it's tank. If this is the issue, it may be time to replace your water heater.
  • Your water heater is making strange sounds -
    A water heater will make some noise as it warms up your home's water. But, if you are hearing loud bangs or clangs it could be that the heating elements inside of your water tank have sediment build up on them and is causing the water to boil and pop.
  • Your water heater is over 10 years old - 
    If your water heater is over 10 years old, it may be time to look into replacing your water heater. As water heaters near the end of their lifespan, it can cost more to run due to it not being as efficient and it may need constant repairs. By having our Knoxville water heater installation team help you replace your water heater we can help save you money in the long run.

If you notice any of these signs with your water heater, we encourage you to call a water heater professional as soon as possible, in order to get the situation professional inspected and taken care of. Replacing your water heater with a tankless system can offer you and your family some tremendous benefits. Contact our water heater pros today to learn more!

Waiting Forever for Hot Water

Is your bathroom the one at the far end of the house, away from the heater, that takes like half an hour to get hot? This is because your plumbing was installed without a re-circulation line – a heated line of hot water that runs near all the fixtures in the home, providing hot water very quickly.

This is a problem that can absolutely be corrected! In fact, there are a number of ways to solve this, and we would love to tell you about each option. One potential solution is that we could install a tankless water heater in the bathroom, giving you immediate access to a never-ending flow of hot water. Give us a call today so that we can resolve this problem and save you time, irritation, and money on your next water bill.
