Electric water heaterscan be shut off at the breaker box and may have an additional breaker closer to the heat pump. Gas andtankless water heaterswill have a cut-off valve, usually with a red handle, along the line leading to the hot water heater. With the water supply on, turn on the gas and connect the tankless heater to the power by closing the circuit breaker. Calibrate the unit for the installation by adjusting the DIP switch settings according to the guide in the manual. Press the on/off button and test for normal operation by turning on a hot water faucet. In addition, the installation of some heaters may require a permit.

Power venting adds around $300–$600 to the water heater’s price, plus $300–$500 for more wiring and electrical work from a professional electrician. Direct venting, on the other hand, adds $500–$1,000 to your total. Because they don't store hot water, tankless water heaters are more efficient than hot water tanks. They only use energy to heat water when water is in use. Direct vent water heaters bring combustion air from outside and exhaust gasses directly outside your home. Once the PVC combustion air and flue piping are roughed in, the gas line is run next, followed by the cold- and hot-water piping. The gas piping in this installation is steel, but you can also use corrugated stainless-steel tubing . Venting systems vary—some models use a single proprietary pipe for handling intake and exhaust , others use two separate proprietary pipes. The heater shown here is a two-pipe setup that uses solid-core PVC pipe. Remove any gas piping that is attached to the old water heater’s gas valve. A tankless water heater continually heats the water running through the faucet. Gas units are more expensive to purchase at around $700 for a 50-gallon tank. However, the operational cost is less than an electric model. The products and services we review may not be right for your individual circumstances.
