Heat pump water heater installation by tank capacity: Annapolis vs Rockville
Hybrid heat pump water heaters use a storage tank, so they're sized in gallons by household — but because they recover heat efficiently, a 50-gallon hybrid often serves a home that needed a 65–80 gallon electric tank.
| Size | Annapolis | Rockville |
|---|---|---|
| 40 gal (1–2 people) | $2,350–$3,900 | $2,350–$3,900 |
| 50 gal (2–4 people) | $2,550–$4,350 | $2,550–$4,300 |
| 65 gal (4–5 people) | $3,000–$4,550 | $2,950–$4,500 |
| 80 gal (5+ people) | $3,300–$4,750 | $3,250–$4,700 |
Treat these as 2026 localized estimates for heat pump water heater installation, not quotes from a contractor.
What water heaters pros earn in each metro
Labor is about 55% of a heat pump water heater installation bill, so local wages drive most of the gap. These are real metro hourly wages for skilled installers (BLS OEWS), not estimates.

Cheapest time for heat pump water heater installation in either city
Winter is when tanks fail most, because cold incoming water and heavy demand push an aging unit past its limit — right when everyone needs an emergency replacement at emergency prices. Swap it proactively in a slower month instead.
Tank or tankless — and what should you budget?
Tank, tankless or heat-pump — the format you pick shapes the bill today and the utility bill for years after. Our editors weigh the trade-offs.
The simple-swap case
A matching tank replacement skips every costly upgrade that comes with changing formats. Same footprint, same connections, same vent, so labor stays low and the crew is usually gone by midday. It's the obvious answer when the budget is thin and the old setup was never the problem.
The tankless case
Tankless costs more upfront and may need a gas-line or electrical upgrade, but it lasts longer, never runs out of hot water and trims standby energy loss — strongest for larger households planning to stay put.
The heat-pump case
A heat-pump (hybrid) water heater costs the most upfront but slashes operating cost and earns the strongest utility rebates where offered — the long-run winner where the install location suits it.
Budget and time horizon settle this more than any spec sheet. A tank clears the lowest hurdle, tankless buys convenience and a longer life, and a heat-pump chases the cheapest years of operation once it has the space to run.
