Should I Repair Or Replace My Tankless Water Heater?

If you already have a tankless water heater, you know the benefits associated with it: more efficient energy costs, virtually unlimited hot water, lower space requirements, etc. Having a tankless water heater in your home is like having your own personal, reliable water system that saves you money and gives you that hot water you need. Until it stops working, and when it stops working, you could be at a loss to know what to do next.

Having a tankless water heater repair performed is the easiest and cheapest option. Since the heaters last nearly 20 years, it should be the first thing you investigate to see if you can get it operating again. If you need to replace it though, you'll have to find someone who can handle tankless water heater installation, since it's more complex than the average storage tank water heater. Below is a list of questions to ask yourself as you're considering whether to repair or replace your unit.

How Often is It Needing Repairs?

At some point, nearly everything in your home will require repairs, and the same goes for your hot water units. If you notice that you're having to hire tankless water heater repair services several times a year, you may be better off having a new one installed instead of continuing to have it repaired. It could be an indication that the unit that's installed isn't working properly, or a problem with the tankless water heater installation itself.

What Kind of Repairs is It Needing?

Tankless water heaters have very similar issues - sediment buildup, system overload, ignition failure, to name a few - so if your problem is one of those, it won't help you to simply install a new unit. Sediment buildup, for example, is usually the result of hard water which affects nearly 85% of homes in the United States. Instead of having a whole new system installed, ask your plumber about adding a water softener to treat the underlying issue.

How Old Is It?

You may think that tankless water heaters are relatively new, when in fact, the first one was invented in 1929. It came in a variety of different designs that look totally different from today's models, so just because you never installed a tankless water heater in your home doesn't mean you don't have one. Inspect your model and inquire about the average lifespan; if it's approaching the estimated lifespan for your unit, have a new one installed instead of scheduling a tankless water heater repair.
