Does a Boiler Need Electricity?

Learn whether your boiler needs electricity to operate and what happens during a power outage.

Boilers and Electricity

Even though most boilers use natural gas as their primary heat source, they still rely on electricity to function properly.

Why Electricity is Needed

• Ignition: Modern boilers use electronic ignition instead of a standing pilot light.
• Pumps: The circulator pump that moves the hot water through your radiators or in-floor heating requires electricity.
• Controls: The thermostat, zone valves, and internal computer board all need power.

Power Outages

During a power outage, your boiler will not be able to heat your home. If you live in an area prone to frequent outages, consider a backup generator to keep your heating system running.
