We install many different products and each has their own manufactures’ required installation. Remember this is a short over view to how a tankless water heater is installed. The length of time it takes to install a tankless water heater will vary depending on what items have to be changed for installation. Usual installation time is 6-8 hours.
- Locate where the unit is to be installed, inside or outdoors. These units fair well in all areas of the home. Basically the best place to put a tankless is where the old tank or tanks were located.
- Remove the existing tanks.
- Build a frame for the new unit to be located.
- Cut all the water lines and emergency relief valve for installation under or on the left side of the unit.
- Connect the water lines and PRV (pressure relieve valve) to the correct line. We use isolator valve kits to connect the water lines to the system.
- Hookup the gas lines to the appropriate gas inlet using the correct sizing of the gas line under code.
- Hook the unit up to the electrical plug in.
- Install the venting for the unit. The correct venting will have to take into consideration the makeup air available, length of run, whether or not you need a condensation tee and where it will be run. And the type of venting you plan on using. See manufactures spec sheets for the correct venting type.
- Check for leaks on water, gas and ventilation. Remove all debris.
