Issues That Can Impact Tankless Water Heater Performance

It’s a given that a reliable water heating system is something every household needs. While traditional tank-type models have been the norm for many years, tankless water heaters have also become increasingly popular due to their energy-saving benefits and compact size. Contrary to what many believe, however, tankless units are not super machines and can also experience issues that can affect their performance. A.M. Plumbing & Rooter, the go-to expert in water heater repair in Murrieta, CA, shares some common concerns that can impact the efficiency of tankless water heaters.

Mineral Buildup

A tankless water heater can heat water on demand, but this process can be hindered if minerals like calcium and magnesium accumulate in the system. These minerals can form a layer of scale inside the unit’s heating element, making it less efficient and causing it to work harder to heat water. This can lead to increased energy consumption and higher utility bills. To prevent mineral buildup, it is recommended to have the unit flushed regularly. For areas with hard water, installing a water softener can also help reduce the amount of minerals in the water supply and prevent buildup.

Incorrect Sizing

Tankless water heaters come in different sizes, and choosing the right one for your household is crucial. If you have a unit that is too small for your needs, you may experience issues with water pressure and temperature consistency. On the other hand, if your unit is too large, it can lead to wasted energy and higher costs. It’s important to consult with professional water heater services to determine the appropriate size for your home’s hot water demands.

Cold Water Sandwich

A “cold water sandwich” happens when a burst of cold water interrupts the flow of hot water, especially during multiple, quick uses. This issue often occurs because the water already heated in the pipes is used up, and there’s a slight delay before more hot water reaches the faucet. This is more of an inconvenience than a performance failure but is still worth noting.

Ventilation Issues

Proper ventilation is crucial for a tankless hot water heater, especially gas-powered models. Inadequate ventilation can cause combustion gases to accumulate, leading to poor performance or even dangerous situations like carbon monoxide buildup. Make sure your unit’s ventilation system is correctly installed and maintained according to the manufacturer’s guidelines.

Improper Installation

A water heater installation should be done by a qualified technician to guarantee proper functioning. Improper installation can lead to a range of problems, from inadequate water flow to frequent breakdowns. Not to mention the possibility of voiding the unit’s warranty if the work is done by an unlicensed individual.
