The current system in PG&E territory encourages me to prefer gas to electricity everywhere I'm able to make the choice. That's surely worse.

- Panzer04 5y agoOnly if it means you’d prefer resistive heaters to heat pumps. In home gas is more efficient than a resistance heater.
- zbrozek 5y agoFalse; the heat pump is still more expensive. You need COP of >=4 with baseline rates, and it only gets worse from there (the baselines are tiny, and TOU is also bad). Heat pump water heaters only barely scratch 4 under ideal conditions, so you'll generally do worse with a HPWH than with a condensing gas one. Arithmetic is about the same for home heating systems. Basically around here (PG&E) you should only electrify if you can also get your electrons from not-the-grid.
