When facing a repair, knowing the replacement cost is essential. Traditional tank heaters last 8-12 years. If your unit is over 9 years old or the repair estimate exceeds 50% of a new unit's price, replacement is likely the best choice. Total replacement costs typically range from $1,600 for a standard tank to over $3,000 for a high-efficiency model. https://www.amenify.com/blog/water-heater-replacement-cost-installation-prices-guide
