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

|---|---|---|
| 5–7 GPM (1–2 people, 1 bath) | $2,300–$4,200 | $2,000–$3,750 |

Cheapest time for tankless 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 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
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
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.
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.
