如何更换油箱型热水器

Plumbing and heating expert Richard Trethewey takes us on a house call to relieve a homeowner’s stress. With a 16-year-old water heater lurking in the basement, the homeowner is expecting it to fail at any moment, so Richard suggests they swap it out with a new unit.

如何更换油箱型热水器

Note:坦克型热水器，尤其是气体燃气品种的热水器，应由许可的管道机代替，并且应确保该项目的许可证。

1. Locate and shut off the water valve. It should be within a few inches from the top of the water heater.
2. 找到并关闭燃气阀。大多数燃气阀将具有显示阀门位置的线。该线应垂直于管道，以确保气体关闭。关闭阀门后，使用一对水泵钳子打破燃气阀下方的联合装配，并断开管道的连接。
3. Attach a garden hose to the drain at the bottom of the old water heater. Run the hose to a floor drain if there is one, or attach it to a pump. Using a screwdriver, open the drain by turning the stem counterclockwise and let the tank drain.
4. 在现有的铜管上选择两个斑点进行切割，并确保将其切成足够高的新储罐，如果它更大。在将管道切割器放在管道上之前，请使用砂布清理管道。将管道切割器拧紧到管道上，然后将其拧紧直至管道切割，每次旋转一次。还要在另一个铜管上重复。
5. 从热水器和烟囱的顶部卸下烟道管。一些混凝土可能会破裂，但是当安装新烟道时，这将进行修复。从其位置卸下旧热水器。
6. 使用管扳手从旧热水器中取出饰边。从热水器的顶部以及电子控制处的底部卸下铜管存根。
7. Carefully place the new water heater in its location. Make sure it’s level by placing a level on top of the heater and using shims underneath. Mark the new flue’s location on the chimney with a pencil.
8. 应用程序ly pipe thread tape to the pipes sticking out of the top of the water heater, running the tape in a clockwise direction. Install the copper piping to the top of the water heater using a pair of water pump pliers to tighten the pipes in place.
9. 应用程序ly gas-safe pipe dope to the gas pipes and reinstall them using pipe wrenches. Be sure to tighten them firmly to prevent leaks.
10. Solder the new pipes to the existing water pipes using a gas torch, flux, and lead-free solder. Reinstall the vacuum valve in the top of the fitting attached to the water heater. Turn the water on and let it fill the tank.
11. If necessary, chip away the chimney using the cold chisel and a hammer. Install the new flue using self-tapping screws and a screw gun. Mix concrete and use a trowel to patch the hole around the flue to ensure gas cannot make its way back into the home.
12. Install an overflow pipe on the side of the water heater using thread tape and water pump pliers.
13. Turn the gas back on and check for leaks. Set the water heater to the desired temperature.
14. Date the water heater by writing the month and year it was installed on the side.

理查德（Richard）建议，一旦新的热水热水器达到生命的尽头，锅炉也可能会在其生命的尽头。那时，最好的解决方案是替换锅炉和加热器如何使用组合锅炉的方法。
