Just came across this new rule, via this article: https://www.sfchronicle.com/climate/article/california-electric-19563602.php
2027 is when they ban sale of new replacement gas water heaters.
They talk about a few solutions, like low voltage electric heaters, and load sharing plugs to share a dryer plug among the water heater and a electric dryer. So that could do it for a lot of people.
But I’d guess a surge in panel replacements will happen within the next 2 years.
Especially since new gas furnaces will be banned in 2029.
Also, obligatory Fuck PGE. We have higher rates than most of the rest of the world and it’s all the fault of the corrupt PUC and PGE.
Rheem makes a 120v-based series of heat pump water heaters now. They were specifically designed for homes with gas water heaters and not enough 240v outlets. I won’t be surprised if/when other manufacturers follow.
If you have an attached garage, you might consider having it installed there to suck up all the summer heat.
If you’re worried about peak electricity usage, you can put your water heater on a timer so it’s only active during the hours you need it. Some water heaters come with this feature built in. Modern water heaters hold heat well, like a battery. So you won’t lose much heat from the water when the power is cut. Technology Connections did a good video on this subject.
Be sure to check for city, state, and federal rebates when replacing your water heater. They can cut costs significantly.
Nyle and GE have 120V models too, or at least will have them on the market soon. I’ve worked on field testing them in California specifically. Transitioning to heat pump water heaters will help cut down on smog too. Good call on checking rebates, there’s a ton money available and some incentive finders are out there to help.
