Renovation vs. New Install
The article argues against gas stoves/appliances, but these arguments would only be applied (practically) to new installations. The cost of replacing gas with electric would be prohibitive, considering the existing risk of keeping the gas.
In my situation, an old, 125-year-old house equipped with gas, and electrical service not as updated as in a modern house, the stove is gas. In fact, it is a gas-and-gas stove, heating part of the house. I have 4 other direct-vent gas fireplaces throughout the 2-story house. The house is insulated, with Pella windows, so it is not "drafty", but I'm sure that air does circulate from outside.
The stove is vented up the chimney (B-vent), which is located in the center of the house.
What would my options be, if I had wanted to eliminate the health risks of gas?
1. Buy a new gas stove, place it on an exterior wall, with a range hood venting outdoors. Then I would need to replace the heater with another direct-vent fireplace (these cost north of $3,000).
2. Keep the present setup, install a range hood, and run the ductwork across the ceiling to an exterior wall, making the kitchen look like a factory.
3. Ditch the gas stove, and wire for electricity. Even more thousands for rewiring and replacement of heater.
In these possibilities, the cost/benefit does not outweigh my risk. I have lived with gas for 65 years. I'm comfortable with the present situation, but if I were building new, I probably would go all-electric. I have multiple CO detectors.
My only concern is if and when the gas-and-gas stove becomes unrepairable. No plumbers or gas co. employees will touch it.
On the other hand, if I got rid of that stove, I would not need my chimney, and I could install a cupola at the peak of the roof.
