Tankless-Done-Right is passionate about protecting you and your home. We know a permit is required to install a tankless heater and many units are being installed without one by other companies, leaving your largest investment (your home) in jeopardy. Most customers appreciate honesty. Tankless water heating is not for everybody. Some homes just are very difficult to install a unit properly because of gas or venting requirements. We will be straight-forward and honest by telling you what it will take to have a proper installation.
