While some homeowners may feel confident in their ability to install a tankless water heater on their own, we generally advise against it. Proper installation of a tankless water heater involves handling gas, electricity, and water, which can be dangerous if not done correctly. Additionally, a professional installation ensures the unit operates efficiently and safely. Incorrect installation can void the manufacturer’s warranty and potentially lead to significant repair costs down the line. At Water Heater Doctor, our experienced team can handle the installation process seamlessly, ensuring your peace of mind.
