Overview

Water heater prices have a wide range, and the sticker price is just part of the equation. A $500 tank heater and a $2,000 tankless unit look very different on the receipt, but operating costs, lifespan, and installation expenses change the real math. Here's what each type actually costs and what drives the price differences.

Cost Breakdown

Tank Water Heaters

Gas tank (40-50 gallon): $400-$900 for the unit. Electric tank: $350-$800. Larger tanks (60-80 gallon) add $200-$400. High-efficiency models with electronic ignition and better insulation run $100-$300 more than standard. Brands matter less than you'd think -- most tank heaters use similar components. The price difference between a Rheem and an AO Smith in the same class is usually under $100.

Tankless Water Heaters

Gas tankless (whole-house): $800-$2,000 for the unit. Electric tankless (whole-house): $500-$1,200. Point-of-use electric tankless (single fixture): $150-$350. Condensing tankless models (highest efficiency): $1,200-$2,500. Major brands like Rinnai, Navien, and Noritz sit at the higher end. Budget brands are significantly cheaper but have shorter warranties and fewer features.

Hybrid Heat Pump Water Heaters

Heat pump hybrid units: $1,200-$2,500. These use a heat pump to extract warmth from surrounding air -- dramatically more efficient than standard electric. They qualify for significant federal tax credits ($2,000 under the current IRA provisions) and utility rebates. After incentives, the effective cost can be lower than a standard electric tank.

What Drives Price Differences

Size (gallon capacity or GPM flow rate), fuel type, efficiency rating (Energy Factor or UEF), brand, and features like WiFi connectivity, self-cleaning systems, or condensing technology. Higher efficiency always costs more upfront but saves on operating costs. The right choice depends on your usage pattern, fuel costs, and how long you plan to stay in the home.

When to Call a Pro

Get quotes from 2-3 plumbers before buying. Many plumbers mark up the unit price but offer competitive total installed prices. Some will price-match if you supply the unit yourself.

Bottom Line

Tank heaters: $400-$900. Tankless: $800-$2,500. Heat pump: $1,200-$2,500 (before rebates). The installed cost -- unit plus labor plus any modifications -- is what matters. Always factor in operating costs over the expected lifespan to find the real value.
