THE MATH

Replacement formula

Total cost = unit + labor + disposal

Water heater replacement has three costs: the tank, the plumber's installation labor and hauling away the old unit.

PRACTICAL EXAMPLE

A 50-gallon tank

A $900 tank with $300 labor and $100 disposal gives a total of about $1,300.

FAQ

Frequently asked questions

Tank or tankless?

Tank heaters are cheaper upfront ($900-$1,800 installed); tankless cost more ($2,000-$4,000) but last longer and save energy.

Electric or gas?

Gas heaters cost less to run where gas is available; electric is simpler and safer to install.

Do I need a plumber?

Yes — water heaters need code-compliant plumbing, venting and sometimes electrical work.
