Repair or Replace a 10-Year-Old Water Heater?

Start with these example inputs

• $700 repair quote
• 2 years expected life after repair
• $2,200 standard tank installed
• $4,200 heat-pump water heater installed

These are examples, not recommendations or market averages. Replace every number with your own quote, rates, expected life, and required installation costs.

What to stress-test

Add electrical or condensate work if required, then test local energy cost and repaired life. A heat-pump option should not win simply because hidden installation costs were omitted.

What the example teaches

Do not ask the calculator to predict the future. Use it to expose the threshold: how much repaired life, future cost, or operating savings must be true before one path becomes less expensive inside the stated horizon.
