No Power? Here’s What Happens to Your Tankless Water Heater

A power failure can quickly ruin your everyday routine. But among the homeowners, the tankless water heater system is forgotten. Unlike conventional tanks, tankless tanks are electrically powered. What happens during the power outage, then?

We can simplify it to give you an idea of what to expect and what to do next.

Do Tankless Water Heaters Work Without Power?

In short, no. Tankless water heaters do not stop working when power is cut off. Gas models also require electricity to power vital parts. Such systems require electric components to operate, such as:

• Ignition system to light the burner
• Control panel to regulate temperature
• Sensors to monitor water flow and safety
• Venting systems in some units.

Thus, the unit cannot warm water without electricity. Power will not come back till you get hot water.

Why Tankless Systems Require Electricity?

Tankless water heaters are technologically advanced. Consequently, they provide hot water at will. Power, however, is a prerequisite to that convenience.

The reason why electricity is important is as follows:

• It triggers the heating immediately.
• It drives safety shut-off functions.
• It regulates temperature precision.
• It promotes the use of digital displays and settings.

Conversely, conventional tank heaters hold hot water. Therefore, they can also supply some hot water during outages. Tankless systems have no water storage; they turn off.

What Happens During a Power Outage?

Your tankless water heater automatically switches off when power is lost. There are things you can see at a glance.

Immediate Effects

• None of the taps had hot water.
• Unit display is switched off.
• System becomes inactive

After Power Returns

• In most cases, the system restarts automatically.
• Layers tend to be stored.
• The hot water is regained within a few seconds.

But, a unit reset may be necessary in some cases. This depends on the model and the outage duration.

Can You Still Use Water?

Yes, it is still possible to use cold water even without electricity. Until the water supply is cut off, your plumbing system will remain in operation.

Nevertheless, remember:

• The shower will be cold.
• Dishwashing becomes harder
• There may be a delay in laundry cycles.

Hence, it is prudent to schedule in advance in case storms or outages appear imminent.

How to Prepare for Power Outages?

You can save yourself by preparation. Outages are uncontrollable but can be minimized.

Smart Preparation Tips

• Add a backup power source, such as a generator.
• Store insulated containers of hot water for emergencies.
• Arrange regular maintenance inspections.
• Familiar with the reset procedure of your unit.

Most of the homeowners seek professional assistance at this stage. Drain Right Plumbing & Rooter INC can help with that. Their staff helps you prepare your tankless system for unforeseen circumstances.

Should You Use a Backup Generator?

Yes, a generator can power your tankless water heater. But you have to select the appropriate size and type.

The Advantages of a Generator.

• Keeps hot water running.
• Operations of other vital appliances.
• Provides convenience during long outages.
• Important Considerations
• Check the wattage needs of your heater.
• Install with a qualified person.
• Be safety conscious.

An adequately installed generator can go a long way in times of emergencies.

Typical Problems of Power Restoration

In some cases, your tankless water heater might not boot up easily. Most units recover quickly, but some problems may arise.

Possible Problems

• Display error codes.
• System not igniting
• Fluctuating water temperatures

Quick Fixes

• Switch the unit off/on.
• Check circuit breakers
• Read the user manual.

In case of problems, call a professional plumber.

How to Reset Your Tankless Water Heater?

Rebooting your system can fix small problems. Nevertheless, manufacturer guidelines should be adhered to.

Basic Reset Steps

• Shut off the power supply.
• Wait for 30 seconds
• Restore power
• Restart the unit

This is a straightforward procedure that can restore your heater to normal in no time.
