How long do water heaters typically last?
Traditional tank water heaters last 8-12 years on average, while tankless models can last 15-20 years with proper maintenance. Lifespan depends on water quality, usage, and maintenance frequency.

Tankless heaters offer endless hot water and energy savings but cost more upfront. Tank heaters are less expensive initially but have limited capacity. Consider your budget, space, and hot water needs.
What size water heater do I need?
For tank heaters, a 40-50 gallon unit suits 2-3 people, while 50-80 gallons works for 4-5 people. Tankless heaters are sized by flow rate (GPM) based on simultaneous usage.

Installation costs range from $800-$1,500 for standard tank replacements, $1,000-$3,000 for tankless units, and $2,000-$6,000 for solar systems. Costs vary by location and complexity.
Can I install a water heater myself?
While DIY installation is possible, it's not recommended due to safety risks, code requirements, and warranty concerns. Professional installation ensures proper setup and compliance.
How often should I flush my water heater?
Flush your water heater annually to remove sediment buildup. In areas with hard water, consider flushing every 6 months to maintain efficiency and prevent damage.
