I had a gas heating system, and gas water heater when I bought the house. When my electric range needed to be replaced, I got a gas stove. When I lose power (which happens two or three times a year, usually in winter), the house heater stops working because it also needs electricity, but the gas range can keep the house tolerably warm (yes I do open the windows a crack for ventilation).
The folks have a gas stove, but a “safety feature” prevents the oven being lit while the power is out. Luckily they also had a generator & portable heaters.
Typical of the idiot proofing of our society, replete with unintended consequences.
