How the Water Heater Size & Cost Calculator works
Tank water heaters are sized by gallons, and the right size depends mostly on how many people shower and do laundry at the same time. Tankless heaters are sized by flow in gallons per minute. Installed prices include the heater, labor, haul-away of the old unit and basic parts.
Example
A family of 3 with 2 bathrooms usually does well with a 50-gallon tank. A gas model installed typically runs about $1,600 to $2,800.
Tips
- Check the label on your current heater for its size and age. Most tank heaters last about 8 to 12 years.
- Rust-colored water, popping noises or water around the base are signs it may be time to replace it.
- In Minnesota, water heater replacement usually needs a permit and a licensed plumber.
Common questions
Is tankless worth it? Tankless heaters last longer and never run out of hot water, but cost more up front. They pay off best for larger households that plan to stay in the home.
Gas or electric? Stick with what your home already has. Switching fuel types adds gas line or electrical work to the price.
