Factors That Affect Water Heater Replacement Cost
Your actual cost depends on several factors beyond just the water heater itself. Understanding these can help you budget accurately:
1. Fuel Type Conversion
Switching from electric to gas (or vice versa) adds $500-$2,000 for new gas lines, venting, or electrical upgrades. Staying with your current fuel type is most cost-effective.
2. Location & Access
Basement installations are typically straightforward. Attic, closet, or garage installations may cost $200-$500 more. High-rise buildings often require $300-$800 additional for elevator logistics and building coordination.
3. Permits & Inspections
Most municipalities require permits for water heater replacement, typically $50-$150. Professional installers handle permit applications and schedule required inspections.
4. Code Updates
Older homes may need expansion tanks ($100-$200), updated venting ($150-$400), or seismic strapping ($50-$150) to meet current building codes.
5. Efficiency Rating
Higher efficiency models cost more upfront but save money long-term. ENERGY STAR certified units typically add $100-$300 but qualify for rebates and tax credits.

Does water heater replacement include removal of the old unit?
Yes, professional water heater replacement includes removal and proper disposal of your old unit. This is included in the installation price. The old water heater is recycled according to local environmental regulations. No additional fees for haul-away with Dimatic Control.
What size water heater do I need for my home?
For tank water heaters: 1-2 people need 30-40 gallons, 2-3 people need 40-50 gallons, 3-4 people need 50-60 gallons, and 5+ people need 60-80 gallons. Tankless heaters are sized by flow rate (GPM). A professional assessment ensures proper sizing for your household's hot water demands.
