Water heater installation cost by job.
Installed-labor pricing for Dumas, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Dumas, Texas, water heater installation costs typically range from $650 to $1,500 for a standard tank unit and $1,500 to $3,700+ for a tankless system. With a median home built in 1970, many homes may need updates to meet current code, such as an expansion tank on closed systems. Texas law requires a licensed plumber and a permit for replacement, so DIY is not allowed. The humid subtropical climate and moderate winter inlet water make a mixed water heating approach suitable. Federal tax credits (30% up to $2,000) are available for qualifying heat pump units, but local utility rebates are limited.
