Potential Culprits in Underperforming Hot Water Heaters

Water heaters are known to be some of the most finnicky fixtures within a given plumbing and HVAC system in the home, and one of their more common issues is a lack of quality hot water.

Wrong Heater Size

In many cases, the issue actually goes back all the way to installation: Your water heater itself might be too small for the home it’s serving. Whenever we’re installing a new water heater in a home, we take detailed steps to ensure it has the capacity to supply the entire home with hot water at all times, even if multiple fixtures are being used at once – sadly, though, not all plumbers take the same care.

If you’re considering a new water heater, one great option that eliminates any capacity concerns is the tankless model. This format provides hot water on-demand rather than using a tank to hold it, meaning you’ll never run out.

Too Great a Demand

In other cases, even for water heaters that are the proper size, the demand from in the home may be too large at certain times. This often happens in homes that have recently upgraded to a new water appliance that uses higher amounts of water, such as a laundry machine or a dishwasher.

Sediment Buildup

For those who still utilize a tank format water heater, sediment may build up in this tank over a period of years if the proper maintenance isn’t done. This sediment can even build to levels where it takes the place of water in the tank, plus prevents the water from hitting the heating source near the bottom that provides it with the heat you need. Regular service and upkeep will eliminate this concern, however.

Water Heater Thermostat

Finally, the thermostat attached to your water heater might not be set to the proper level. This thermostat should always be set to at least 120 degrees Fahrenheit, and can go as high as 140 degrees in some cases.
