Frequently Asked Questions
In 2026, a new water heater costs $800-$2,500 for a standard tank model installed, or $2,500-$5,000 for tankless. Heat pump water heaters run $2,500-$4,500 installed. Factors affecting cost include fuel type, capacity, efficiency rating, and installation complexity. Replacing like-for-like is cheapest; switching fuel types or to tankless costs more.
Tank water heaters typically last 10-15 years with proper maintenance. Tankless water heaters can last 20+ years. Signs your water heater needs replacement include: age over 10 years, rusty water, rumbling noises, leaks around the base, and inconsistent hot water. Annual maintenance can extend lifespan.
Tankless water heaters cost 2-3x more upfront but offer 20-30% energy savings, last twice as long, and provide unlimited hot water. They're worth it if you plan to stay in your home 7+ years, have high hot water demand, or want to free up space. For smaller households or tight budgets, a high-efficiency tank may be more cost-effective.
For tank water heaters: 1-2 people need 30-40 gallons, 3-4 people need 40-50 gallons, 5+ people need 50-80 gallons. Tankless sizing is based on flow rate (GPM) and temperature rise needed. A plumber can calculate exact requirements based on your fixtures and usage patterns.
