Heat pump water heater

HPWH Cost by State

A hybrid heat pump water heater runs $2,200–$4,200 installed nationally for a 50-gallon unit, with local HVAC + plumber labor rates and the cost of a new 240V circuit shifting the band by state. Below: 51 state pages with calibrated ranges.

Quick answer: $2,200–$4,200 typical hybrid 50-gal; $1,700–$3,400 for 120V plug-in; $5,500–$12,000 for premium split systems. Federal 25C credit (which covered HPWHs to $2,000) expired Dec 31 2025.
