Tankless water heater installation by flow rate (GPM): Brentwood vs Burnsville

|---|---|---|
| 5–7 GPM (1–2 people, 1 bath) | $2,300–$4,200 | $2,650–$4,950 |
| 7–9 GPM (2–3 people, 2 baths) | $2,650–$4,900 | $3,100–$5,750 |

Cheapest time for tankless water heater installation in either city
Wait for a winter failure and you're paying rush rates on a unit already past 10 years, when the cold incoming water finally does it in. Replace it on your own schedule in spring or fall and you avoid that premium entirely.
Tank or tankless — and what should you budget?
Before the brand or the size, the biggest decision in a water heater budget is the format. Here's how our editors think through it.
The tankless case
Going tankless means paying more at install — often for a resized gas line or a dedicated electrical circuit — in exchange for hot water that never runs dry and a unit that outlives two conventional tanks. Dropping the standby loss of a constantly reheated reservoir trims the monthly bill on top of that. It fits a full house that isn't selling anytime soon.
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.
The simple-swap case
When money is the constraint and the existing tank has kept up with the household, dropping in the same fuel type and capacity is the least disruptive move. No venting rework, no new gas line, no panel space to find — a plumber can pull the old unit and set the new one before lunch.
Start from how long you'll own the house. A short stay or a tight budget points to a tank, a full household settling in leans tankless, and if the monthly bill is what you're minimizing, the heat-pump's efficiency and rebates pull ahead.

Rarely. The $700 difference is real but one-time, and you can often close most of it in Burnsville by buying in the off-season and getting tighter, apples-to-apples bids. Ongoing factors — energy prices, climate and home condition — matter more over the life of the system.
