For any home or office having tankless type of hot water heaters is a great investment. The latest version is quite efficient and is able to save your money if it is set up properly.

Though it is uncommon, any potential issues can arise if something is not functioning correctly within this unit.

Following are 6 most common problems that you may experience with the tankless hot water heater.

• Buildup of minerals

For all kinds of hot water heaters, mineral buildup within the unit is bound to happen. If water is harder, then chances are even more.

The two main minerals are magnesium and calcium and they will create scaly buildup if not addressed. So, flush your hot water heater regularly once in a year.

• System overload

In case there are many people present in the household, who will be using hot water often then your hot water heater may get overloaded, and eventually struggle to supply hot water or shut down.

In such case, either consider upgrading your water heater or add one more unit which can be better solution in the longer run.

• Cold water sandwich

Usually after using shower by one person, the person initially may continue to get hot water but then later gets cold water.

That is because some hot water was left in your pipeline and after that has flowed out the fresh water may need some time to heat up.

• Exhaust blockage or air supply message

Such message means hot water heater may be having issues with venting or combustion of air. Make sure that vent pipes are properly connected and don’t have any big holes.

Other common reason can be blockage due to bird nest, rodent, wasp nests etc. Possibly you may not be able to see it.

• “No ignition” message

Such message means that hot water heater may be trying to light, however for some reason it is unable to do. Such problem is usually related to supply of gas or venting. Some simple gas problems like unpaid gas bill or empty propane tank can cause it.

You must call your service provider to visit and check.

• Flame failure message

There can be many reasons for gas problem and hence you must call a professional to sort out the issue.
