How To Install An Electric Water Heater
This article provides a detailed guide on installing an electric water heater, emphasizing that while the appliance itself is simple, its installation requires careful attention to building codes, safety, and proper plumbing and electrical connections. It outlines the steps for a handy person comfortable with basic plumbing and electrical work, but also notes that the guide can inform customers working with a professional plumber. The installation process begins with planning, which includes reviewing the product literature and local building codes. Crucial safety measures, such as turning off the circuit breaker and verifying electrical wiring is de-energized with a non-contact voltage test pen or multi-meter, are highlighted as paramount before any work begins.
The guide details the necessary preparatory steps, including removing an existing heater, draining it, and disconnecting its plumbing and electrical connections. It then addresses positioning the new water heater, recommending a water heater stand to facilitate drainage and servicing, and noting the importance of securing the appliance with straps, particularly in areas requiring seismic protection like California. The article explores options for connecting the water heater to the home's plumbing, suggesting copper tubing, corrugated flexible metal connectors, or PEX. While acknowledging PEX as a modern material, it advises that soldering copper tubing might be more straightforward for those new to PEX, detailing the tools and a simple soldering procedure.
Key plumbing installations covered include installing a ball valve for the cold-water supply line and the temperature and pressure (T&P) relief valve. The T&P valve is identified as the most critical safety component, designed to prevent dangerous pressure buildup by discharging water. The article references the International Residential Code (IRC) for specific requirements regarding T&P valve discharge piping, emphasizing that the discharge point must be visible. It also provides instructions for correctly dry-fitting components before soldering and using pipe thread tape for secure connections.
For electrical connections, the guide specifies the need for a separate 240-volt, 30-amp circuit with 10/2 with ground circuit cable for electric water heaters, advising professional help if there's any doubt about correct sizing. It describes connecting like-colored wires and the ground wire, with particular attention to upgrading older plastic-sheathed wiring to metal conduit or flexible connectors if necessary. The article concludes with the critical instruction to fill the water heater with water *before* restoring power to prevent damage to heating elements, followed by bleeding air from the hot water lines and adjusting the water temperature settings, typically set at 120 degrees F.
