The tools needed to install a heater assembly depend on the type of heater. Installation of an electric water heater requires a pipe cutter, soldering supplies, a pipe wrench, a screwdriver and a hammer. Metal tubing, fittings, a measuring tape and pipe threading tape are also necessary.
Soldering is the most complicated and time-consuming task involved in electric water heater installation. The specific soldering materials required are a blow torch, soldering flux paste, steel wool, a wire brush and lead-free solder. A soldering iron, a soldering iron stand, heavy work gloves, a full-face mask and clean rags are also essential.
