October is a good time for Pittsburgh homeowners to think about what happens to their heat when the electricity goes out. A furnace that burns natural gas still usually needs electrical power to operate. Understanding your system’s limits now can help you make a safer plan before colder weather arrives.
Most gas furnaces rely on electricity for their controls, ignition, safety devices, and blower motor. Most modern boilers also need power for controls and circulating pumps, even when gas or oil provides the heat. Heat pumps and mini-splits depend on electricity as well, so none of these systems should be assumed to provide heat during an outage.
If you’re considering backup power for a home in Sewickley, start by identifying exactly which heating equipment and supporting components must run. A generator must accommodate the required electrical load, including starting demands, and a hardwired heating system needs an approved connection method installed by a qualified professional. Have an electrician coordinate with your HVAC contractor rather than choosing a generator based only on its advertised wattage.
Never connect a generator to a household wall outlet or improvise a connection to your furnace. Operate portable generators outdoors, at least 20 feet from doors, windows, and vents, with exhaust directed away from buildings; never run one in a garage, even with the door open. Battery-backed carbon monoxide alarms are essential, and a gas oven, outdoor grill, or camping heater is not a safe substitute for home heating.
For a household in Bethel Park, an outage plan should also include warm layers, flashlights, charged phones, and somewhere safe to stay if indoor temperatures become unsafe. Keep exterior doors closed as much as practical, but leave heating vents and equipment ventilation openings unobstructed. When power returns, allow for normal equipment startup delays; if the heat does not resume, avoid repeatedly resetting the system or opening equipment panels.
