> Seattle has piped gas,

This is block by block. Long ago Seattle asked home owners on each block to foot the bill to run gas. Many blocks said yes, some said no. For blocks where only 1 side was developed, the cost was higher and there was a greater chance of everyone saying no. That is what happened on the street I grew up on, when the city had asked everyone to pay for gas lines, there were so few houses on that working class block that it was cost prohibitive for everyone to pony up how much $ would have been needed.

So instead people had oil furnaces installed and now that block will at some point require serious environmental remediation. :/

It's interesting all the permutations there are out there. We have gas from PG&E. Our house has an electric clothes dryer, gas stove with dual-fuel oven, gas furnace, and gas water heater. No air-conditioning other than a portable unit for "emergency" heatwave and AQI events. Our furnace is ancient, and the winter gas bill is the painful part.

I have a long term interest in full electrification, but find the process daunting due to the interlocking set upgrades. Between insulation envelope upgrades and electrical system upgrades, there is a lot of potentially disruptive work needed to even allow permits to be issued for heat-pump HVAC and water heater or fully electric kitchen.

If the internal wiring also needs much work, it threatens to be almost as invasive as a gut renovation. Then, I ponder what other work we'd want to piggyback on it. But then it all sounds too much for life and budgets, so we procrastinate...

Were you there for the earthquake in 2001? I was. I still find it surprising there hasn't been another large quake in Seattle since then. Pretty fortunate.

Wow that's interesting. If you have to do it all over again, would you still get the heatpump?
