Tankless Water Heater Questions

Suspecting that something is wrong with your water heater is never fun. But when you have a tankless heater, you don’t have to worry about dozens of gallons of heated water damaging your home. Here are some of the most common problems with tankless water heaters and the first steps you can take:

Tankless Water Heater Questions

1. My tankless water heater is leaking. What do I do?

Whether you hear a drip or see water buildup, the first thing to do whenever you see a leak is to shut off the local water connection if you can. If water is leaking out of the box, set down a towel or bucket to catch the water. Then contact a trained technician. It’s much more likely to be a loosened valve instead of a broken unit, so calling quickly can cut down the repair costs.

2. Why isn’t the water getting as hot as it used to?

Tankless heaters are energy-efficient and they give you immediate access to hot water. But they can only provide hot water to one or two areas at a time. If your shower is lukewarm, make sure your washer and dishwasher or off. If the water still won’t heat up:

  • check the temperature gauge,
  • lower the water pressure so the water spends more time near the heating coils, and
  • call a technician if nothing works.

3. Why is the water harder?

Your region might have hard water, and your tankless system won’t let minerals and sediment sink out of the way like with your old tank. Talk to your plumber about filters, water softeners, or potential rust buildup. Contaminants in the water can be dangerous, so don’t wait to call in someone who can help.
