State Premier Hybrid Water Heater — Specs, Features & Reviews

State's heat pump electric line — 50/66/80-gallon HPX-series. Energy Star, IRA tax credit eligible, 10-year warranty.

Updated May 2026 · State Water Heaters

The Premier Hybrid line is State\'s heat pump electric water heater — value-tier equivalent of AO Smith Voltex at typically $200-400 less. Same heat pump architecture (compressor + evaporator + resistance backup), same Energy Star certification, same federal IRA $2,000 tax credit eligibility.

Premier Hybrid lineup

Note: the older Patriot Hybrid (PHPT series) was replaced by current Premier Hybrid (HPX series). Same product family, updated branding and chassis.

How it works

A small compressor and evaporator (like an air conditioner running in reverse) extract heat from ambient air and pump it into the tank. Resistance backup elements fire when heat pump can\'t meet demand or ambient is too cold. The combined system delivers 3.0-3.5x UEF — three times more efficient than standard electric.

Modes

  • Hybrid: heat pump primary, resistance backup when needed. Default mode
  • Heat Pump Only: maximum efficiency, slow recovery (8-12 GPH)
  • Electric Only: resistance backup only (used when ambient too cold for heat pump)
  • Vacation: minimum heating during away periods

Install requirements

  • 240V dedicated 30A circuit (same as standard electric)
  • 700+ cubic feet of unconditioned air space around the unit (critical — heat pump needs ambient air to operate)
  • Ambient 40°F+ for heat pump mode
  • Condensate drain (4-8 gallons/day)
  • Clearances: 7" front, 4" sides, 7" top
  • Compressor noise: ~50-55 dB — not appropriate for finished living spaces adjacent to bedrooms

Federal IRA tax credit

30% of project cost up to $2,000 per year. Premier Hybrid 66-gal at $1,849-2,249 + install $700-1,800 = $2,549-4,049 total. After IRA credit: $545-2,049. Stack with state/utility rebates (some markets) to net $500-1,500 actual cost.

Warranty

10 years tank / 10 years parts / 1 year labor. Matches AO Smith Voltex.
