Water Heater Replacement in Johns Island, SC

Expert Water Heater Replacement in Johns Island, SC

When a heater has reached the end, what you replace it with should suit your house and your water — and on Johns Island the water is part of the decision.

Think about your water first

If you are on a well with iron or hardness, a tankless unit will scale up unless the water is treated. We would rather fit a conventional tank and a proper filter than sell you the more expensive option and watch it disappoint you. On treated or city water, tankless works very well.

Getting the size right

Larger homes on the island often have long runs from the heater to the far bathrooms, which is why you wait so long for hot water. Replacing is the right time to look at whether the size and the layout actually suit how your household lives.

Where it sits

If your heater is in the attic or above a living space, it needs a drip pan connected to a drain. A number of older installations here do not have one, and it is the difference between a small puddle and a ruined ceiling.

What we include

  • Removing and disposing of the old unit
  • An expansion tank where required
  • A pan and drain line where it sits above living space
  • The permit and inspection
  • A clear price agreed before we start
