100A typically supports HPWH addition

  • Is a 120V plug-in or 240V hybrid model being quoted?
  • Is condensate drain work included (drain pan, pump, or gravity routing)?
  • Is the install location large enough for proper airflow (typically ≥700 cu ft)?
  • Is sound rating (dB) acceptable for the location?
  • Is old water heater removal and disposal included?
  • Which rebates require pre-approval, and have they been applied for?
  • Is the 240V circuit, outlet, or breaker work included if needed?
  • Are permits and inspection included?
  • Will the cold-air output affect any nearby living space?
  • What is the warranty on tank, compressor, and labor?

Surprise odds are approximate planning estimates, not measured rates; cost ranges are sourced where shown. How this works.

Method: each cost line is drawn from a triangular distribution and correlated by a shared market factor (~0.5), then sampled across 10,000 outcomes (a Monte Carlo simulation); the most-likely value and range emerge from the simulation, not the band. A planning simulation, not a quote.

Frequently asked questions

How much does a heat pump water heater cost in Modesto?

In Modesto, CA, a 50-gallon hybrid HPWH typically runs $3,091–$5,901 installed, scaled to California labor rates. A 120V plug-in unit is cheaper. The calculator above refines for capacity, voltage, and install location.

What is the monthly operating cost in Modesto?

At California retail electricity of 35.3 cents/kWh, an HPWH for a 4-person household in Modesto costs about $44 per month to run — roughly 1/3 the energy use of a standard electric tank water heater.

What rebates apply to HPWHs in Modesto?

The federal 25C credit (which covered HPWHs up to $2,000) expired Dec 31 2025 under OBBBA. DOE HEEHRA provides up to $1,750 for HPWHs in income-qualified households where California has launched the program. The table above shows 3 applicable programs.

Where should an HPWH be installed?

HPWHs need about 700 cubic feet of free air to maintain efficiency. A conditioned basement or utility room works well; an unconditioned garage is fine in moderate climates but risky where winter ambient drops below the unit cutoff temperature.
