I bought this 1941 home back in '97. It had a functional gas water heater, and a forced air gas powered central heating system. I'm about the third owner. The second owner remodeled the place in the '60's, adding a master bed/bath to the rear, converting a bedroom to a family room off the kitchen, creating an enclosed bricked in patio on the side with a second kitchen, etc.
The one change the previous owner made that I didn't like was when they remodeled the kitchen, they made it all-electric. I'm certain the original home had a gas kitchen. One of the first things I did was hire a plumber to extend the gas line to the all-electric cooktop area, and then I replaced the electric cooktop with a gas unit. The wall oven is still electric, though. That's OK.
About a year and a half ago I lost most of my sense of smell (no, not from covid). One of the first things I did was to get one of those Kidde combo CO/Explosive Gas alarms. My sense of smell is gradually returning but I don't know if it will ever be what it once was. Anyway, the CO/Explosive Gas detector helps me sleep better, LOL.
Yes, gas is cheaper than electricity here. However, the latest gas bill shows it at $2.02/therm for "Tier 1", and at $2.50 for "Tier 2". I recall someone stating their gas cost them about $1/therm. Everything seems more expensive here in Cali. Fortunately the biggest gas use is in winter for the central heating. Around April-May that will be done. I hope. The price for natural gas here has gone up 25% (Dec 2020-Dec 2021) in one year!
