Heat Pump Water Heater FAQs
Palo Alto’s most frequently asked questions about heat pump water heaters
The City’s program to support Palo Altans in switching from old gas water heaters to cleaner, safer, and smarter heat pump water heaters is picking up steam. Residents have asked us to answer lots of questions about switching. Here are the top five:
1. Honestly, how much will this actually save me?
The City's Emergency Replacement & Fast Service Program can restore your hot water in as little as two days while helping you switch to an energy-efficient heat pump water heater. The price for a standard 65-gallon heat pump water heater installation is as low as $2,100. Actual costs may vary depending on site preparation and water heater location, with an average project cost of $2,800. Weekend service is available for an additional charge.
2. Seriously, do I need to swap out my old gas water heater?
Though the City is no longer enforcing a ban on gas water heaters in new homes, switching now makes a lot of sense. Gas water heaters will only become more problematic over time. Heat pump water heaters are better for the environment while delivering all the hot water you need when you want it. Right now, today, the City will do everything you need to switch.
3. Realistically, what happens if the power goes out?
The same with gas water heaters: You can use the hot water you have in the tank, but you’ll need electricity to produce more. (Gas water heaters still need electricity to power the pump.) Thankfully, the City is simultaneously striving to help residents switch while upgrading our electrical grid further to be more efficient and resilient.
4. Basically, how does the installation work?
To start, all it takes is to call us at (650) 713-3411. You will be connected with our Home Energy Advisor, who will guide you through the process. If you want, we’ll handle the inspection (when it’s convenient for you), estimates (that include every last thing, including permits), installation (which should be done in a day), payment (with all the rebates we promised), and inspection (to make sure everything was done right and we can provide the permit).
5. Approximately, how much will I save on utility bills?
We can’t give you a hard number because everyone uses water differently. That said, gas will only get more expensive. Heat pump water heaters, on the other hand, are up to three times more efficient than gas models. And we could all use appliances that are cleaner, safer, and smarter.
