Water heater installation in Woodstock, Illinois typically costs between $750 and $1,750 for a standard tank unit, and $1,750 to $4,400 or more for a tankless system. With most homes built around 1986, many systems are nearing the end of their 10-15 year lifespan. The cold continental climate means winter inlet water is very cold, increasing demand on the heater.
