Whole house water heaters are installed in a single location and supply the hot water for all fixtures and appliances in the home. Both tankless and tank-type water heaters can serve as whole-house systems, costing an average of $679 to install.
Geiger estimates tankless water heater installations start in the low- to mid-$3,000 price range, and Sauro estimates the price starts at $2,800 to $3,800. Installing a tankless water heater takes much longer, a full eight to 10 hours versus the two to three hours for a traditional water heater installation. And itâs something only professionals should attempt.
