Electrical Capacity
Most full-size units need a dedicated 240-volt circuit. We check your panel first, and in some homes a plug-in 120-volt model avoids a panel upgrade.
Heat Pump Installation
Heat Pump Water Heater Installation San Francisco
Gas tank near the end of its life? A heat pump water heater runs on electricity efficiently and keeps you ahead of new air rules.
- Panel and circuit checked first
- Space and airflow planned
- Old gas tank removed and hauled away
Switching to a Heat Pump Water Heater
A heat pump water heater pulls heat from the surrounding air and moves it into the tank, so it uses far less electricity than a standard electric tank. For homeowners moving off gas, it's the main replacement option.
The Bay Area Air Quality Management District has adopted a zero-NOx standard that phases out new gas tank water heaters, and its board is reviewing the start date and exemptions now. Planning the switch while your current tank still works gives you time to sort out electrical work without a cold-shower deadline.
If your space or panel isn't a good fit for a heat pump, we'll tell you up front and help with replacing your water heater in SF using a standard tank instead.
Site Check
What We Check Before Install Day
Space and Airflow
The unit needs enough surrounding air to work well. In a small closet, that can mean a louvered door or ducting, which we plan before install day.
Cool Garages and Basements
Many San Francisco water heaters sit in garages and basements that stay cool year-round. Heat pumps slow down in cool air, so we set the size and backup mode to keep up with your household.
Condensate Drain
Heat pump units produce condensate. We route a drain line, or add a small pump where there's no drain nearby.
Right Tank Size
Heat pumps recover more slowly than gas, so many homes go up a size. We match capacity to how your household actually uses hot water.
Incentives
Rebates and Running Costs
TECH Clean California and CleanPowerSF, San Francisco's power program, have offered incentives for heat pump water heaters. Programs open and close, so it's worth checking what's available before you buy.
The federal 25C tax credit no longer applies to systems installed after 2025, so don't count on it when budgeting.
Step by Step
How the Switch Happens
-
01
Site and Panel Check
We look at your electrical panel, the space around the current heater and drain options, then recommend a unit and size.
-
02
Electrical Prep
If a new 240-volt circuit is needed, it's run before install day so the swap itself goes smoothly.
-
03
Remove the Gas Tank
We shut off and drain the old tank, cap the gas line safely at the appliance and haul the old unit away.
-
04
Install, Test and Set Modes
We set the new unit, connect water and the condensate drain, then test it and set the operating mode for your household.
Planning Your Budget
What the Switch Costs
Heat pump installs cost more than a standard tank swap. CleanPowerSF puts a typical one in the city at $6,000 to $9,000, and electrical upgrades, ducting or a condensate pump can add to that.
We confirm the price after checking your panel and the install space, so you know the full scope before work starts.
Common Questions
Questions Before You Switch
Do I have to replace my gas water heater now?
No. The air district's standard applies to new water heaters at the time of replacement, not to units already in service. It matters when your current tank needs replacing.
Is a heat pump water heater noisy?
The fan and compressor make a low hum while running. We keep the unit away from bedrooms when the layout allows.
How long does the install take?
The swap itself is often done in a day once the electrical work is ready. If a new circuit or panel work is needed, that's usually done first.
What happens to the old gas line?
We cap it safely at the appliance. If you still have other gas appliances, the rest of the gas line stays in service.
Service Area
We work in homes throughout the city.
