Tankless water heater installation by flow rate (GPM): Arvada vs Lakewood

|---|---|---|
| 5–7 GPM (1–2 people, 1 bath) | $2,600–$4,850 | $2,600–$4,850 |
| 7–9 GPM (2–3 people, 2 baths) | $3,050–$5,650 | $3,050–$5,650 |
| 9–11 GPM (3–4 people, 2–3 baths) | $3,500–$6,200 | $3,500–$6,200 |

Cheapest time for tankless water heater installation in either city
Tanks fail most in winter when incoming water is cold and demand is high — emergency-rate territory. Replacing a 10+ year-old unit proactively in a slow month avoids the premium.
Tank or tankless — and what should you budget?
What a water heater costs to install and what it costs to run rarely move together, and the format is the lever between them. Tank, tankless, and heat-pump each strike that balance differently.
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
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
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.
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.
