Learn more about these tankless water heater maintenance concerns.

Mineral Buildup

Mineral buildup causes problems in regular and tankless water heaters. If your home or business has hard water, it contains a high mineral content. This increases the risk of mineral buildup that can damage your tankless water heater. For example, magnesium and calcium cause buildup that damages your unit.

Set up a maintenance schedule to flush out your water heater twice a year with a mineral descale. Using water softener may also decrease the accumulation of minerals in your tankless water heater lines. Our water heater specialists may recommend other solutions unique to the conditions in your business or home.

Hot Water Demand Overload

Tankless water heaters heat water on an as-needed basis. This means that placing too many simultaneous demands on the system can cause an overload. Let’s say you have the dishwasher going and one or more people taking a shower at the same time you put in a load of laundry using hot water. Your tankless water heater may not be able to keep up with that level of demand. In fact, it could shut down due to an overload.

As a quick fix, you can monitor your usage. Resetting the unit can restore functionality. If your tankless water heater regularly becomes overloaded, it may be time to invest in upgrading your unit or adding a second one in an area of high usage.

Avoid Cold Showers

For customers living in a full household, you may already stagger your showers to avoid overloading the water heater. Still, it’s probable that you’ve run out of hot water in the shower at least once.

This happens when some hot water remains in the line, but the tankless water heater needs time to heat the water. Although these units are called “instantaneous” water heaters, they require time to heat the water supply properly. The further the shower lies from the water heater, the longer the gap between turning on the tap and getting hot water. To avoid this problem, there’s no need to call us. Just wait a couple of minutes to give the unit time to warm up again.

Straining your system can cause your tankless heater to wear out faster. For more tips on preserving your water heater through smart usage, give us a call.

Air Supply and Exhaust Blockage

If your unit displays an error code, it could be an issue with the exhaust or air supply. When airflow becomes blocked, you can read the manual to find out what the error code means. Rather than fumbling around to resolve the problem yourself, contact us to send a certified technician familiar with the manufacturer of your tankless water heater.

From rodents to wasps to birds, animal intrusion represents a large percentage of issues with your exhaust or air supply. We can figure out the issue and recommend a solution.

Ignition Failure

Tankless water heaters have an ignition system that may occasionally fail to light. If your heater is gas-powered, check whether your tank has gas then open the gas and water valves to encourage ignition.

If troubleshooting the problem doesn’t work, call a professional. Our dedicated technicians will get to the root of the problems and replace any malfunctioning parts to make sure your unit runs well.

Flame Failure

Related to gas-powered units, flame failure often results from an electric system or your gas pressure.

Root causes include:

• Low propane tank
• Unpaid gas bill
• Small gas line
• Combustion or regulator failure
• Venting problems
