How much should this gap actually matter?
A 11% gap is meaningful on a project this size — about $400. That's real money, but it's often within reach of off-season timing and a tighter apples-to-apples bid in Boston.

Cheapest time for heat pump water heater installation in either city
An aging tank tends to give out in winter, when it's working hardest against cold incoming water — and that's exactly when replacement costs the most. Get ahead of it.
Tank or tankless — and what should you budget?
Fuel type and household size come after the real fork in the road: tank, tankless, or heat-pump. That single choice sets both the install bill and every hot-water bill that follows.
The tankless case
The tankless premium buys longevity and endless supply: nothing sitting hot around the clock, a lifespan roughly double a tank's, and no cold showers when demand spikes. The catch lives in the setup, since most retrofits need a bigger gas line or an electrical upgrade first. Larger households planning to stay put recover that cost fastest.
The heat-pump case
For the lowest running cost of the three, the heat-pump water heater wins outright, and where utilities offer incentives the rebates behind it are the richest available. You pay for that advantage up front, and the unit needs the right home — a warm, well-ventilated area with real clearance. Wedge it into a tight closet and the savings disappear.
The simple-swap case
If your current tank suits your household and the budget is tight, a like-for-like tank replacement is the cheapest, fastest job — no gas-line or panel upgrades, done in a morning.
The cheapest to install and the cheapest to run are rarely the same unit. Tanks win the first, heat-pumps win the second where the install spot allows, and tankless sits between them — trading a higher upfront number for a supply that never quits.
