Tankless water heaters are a great alternative to traditional tank-based systems. They provide a continuous supply of hot water and save energy. But, sometimes they lose power. This article will look at possible causes and solutions.
- The most common cause of power loss is an area power outage. When the electricity comes back, your tankless water heater will resume normal operation.
- A malfunctioning control panel or electrical connections can also lead to power loss. If this is the case, it’s best to call a professional plumber or technician.
- Certain models of tankless water heaters require battery backup. If it doesn’t work, the unit will lose power even when the main electricity supply is working. Fresh batteries can prevent this.
One customer experienced an unexpected power loss with their gas-powered tankless unit. They called Mastertech Plumbing for help.
The master technician Nate diagnosed the problem as a “cold water sandwich.” This happens when there are short bursts of cold water between periods of hot water usage. The solution was to adjust the flow rate by opening another tap slightly while using hot water. This gave them a steady and consistent flow of hot water.
