Water heater installation cost by job.
Installed-labor pricing for Lake in the Hills, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In Lake in the Hills, water heater installation costs typically range from $800 to $1,800 for a standard gas tank unit and $1,800 to $4,600+ for a tankless model, plus $300–$1,000 for a new gas line if needed. With 84.4% homeownership and a median home built in 1995, many homes have water heaters nearing or past their 10–15 year lifespan. The cold continental climate means cold winter inlet water, increasing demand on the system. Illinois law requires installation by a licensed plumber and a permit; an expansion tank is required on closed systems. Most homes use gas, making a gas unit the recommended choice. The federal 25C tax credit offers 30% (up to $2,000) for qualifying heat pump water heaters, but gas remains the standard.
