Troubleshooting Problems with Your Solar Tankless Water Heater Troubleshooting Problems with Your Solar Tankless Water Heater

A lot of things can go wrong with your solar tankless water heater and since it is impractical for you to call the manufacturer for help every time it malfunctions, you should learn how to troubleshoot your heater. Here are some of the most common problems that you can solve on your own.

Not Enough Hot Water

There are many reasons why your solar tankless water heater may not produce enough hot water. For instance, your solar power collectors may be too small to heat up all the water that your need at home. As a general rule, you need at least 40 square feet of solar panels to provide adequate hot water to the first two members of your household and another 8 to 14 square feet of solar panels for each additional members of the household. If your solar power collectors are smaller that what is required, you should upgrade the size of your panels. You may also change the location of your solar panels to generate the maximum amount of energy. Your roof should be a good place to mount your solar panels.

Another reason why solar tankless water heaters do not produce enough hot water is that its thermostat may be set on low or the dip tube is faulty. If you thermostat is set to low, all you need to do is adjust the setting. However, if the problem is the dip tube, you will need to change the tube to prevent cold water from being dragged out of the tube without heating.

During winter when the temperature is below the freezing point, your solar tankless water heater may not produce enough hot water due to the limited amount of energy harvested from the sun. If this is the case, your remedy is to use an electric or a gas powered water heater instead of a solar heater during the winter months.

No Power

Faulty connection between your solar power generator and your heating system may cause power failure. If the solar tankless water heater does not have power, check your solar power generator and make sure that it is properly connected to your heater. You should also see to it that your solar power generator gets enough power to run your system.

Fluctuating Water Temperature

If your water is too cold or too hot, you need to adjust the thermostat setting on your system. To make sure that the temperature of the water is just right, test the water as you adjust the setting of the thermostat.

Fluctuating water temperature may also be due to unbalanced water pressure in the pipes. To help correct the imbalance, keep your faucets and showerheads tightly closed when not in use.

Noisy Water Heater

The scale formulation of your water heater as well as the expansion and contraction of the metal parts of your solar tankless water heater may produce loud noise. Although a noisy water heater is not exactly a safety threat, it can quite annoying. To minimize the noise, flush the heater at least once a month.
