Water heater:

To install Tank less Water Heater

Decide where you want to install your tank less water heater. Some people choose to install small units at every water outlet, such as under sinks, behind showers and in laundry rooms. Others choose the larger whole-house units, which usually are placed in the lowest part of the house, such as in the basement, and against an outside wall for venting. Decide whether to use natural gas or propane to heat the water. Remove the old system. This will involve first disconnecting the power source at the electrical panel and then removing the connections. The tank must be drained before you disconnect the plumbing lines. Bolt the tank less water heater in place. If you are installing it in the basement it is usually recommended to first mount wood to the concrete walls so that you can screw the heater into place. Smaller units may be mounted on walls on studs.
