According to the water storage method, electric water heaters can be divided into three types: instant heating type, volumetric type (also known as water storage type or thermal storage type), and instant heating type (also known as semi-water storage type); volumetric type It is the main form of electric water heater. According to different installation methods, it can be further divided into vertical, horizontal and floor-standing types. According to whether it is pressure-bearing or not, it can be divided into simple type (open type) and pressure-bearing type (closed type). , according to the volume, it can be divided into large volume and small volume.
Tank electric water heaters generally require more than 20 or even 30 amps of current. They are hot when turned on, have constant water temperature, high heating efficiency, and small installation space. High-quality instant electric water heaters with internal low-pressure processing can add a diverter during installation to supply water to multiple faucets. Products with higher power are installed in bathrooms and can be used for both showering and washing in general households. It is energy-saving and environmentally friendly. Let’s take a look now at how to install an electric water heater!
Tools:
Power tools: cordless drill, impact drill, jig saw, grinder and polisher, angle grinder
Hand tools: hole opener, level Ruler, glass glue gun, tape measure, square square, hammer
Steps/Methods:
1. Determine the installation location, mark the wall with a pen, and then drill holes with an electric drill.
2. Then put in 4 rising nails. Note that the top two have upward 45-degree angles and are used to hang the water heater.
3. Align the hook and hang the water heater.
4. Looking from the side, it looks like this.
5. Wrap raw tape on the figure-eight valve and pay attention to the figure-eight valve.
6. At this time, it is time to turn off the main switch of the water pipe in the home, and then drain the water in the pipe at the lowest outlet in the home.
Note: Be sure to find the lowest water outlet so that the water can be discharged cleaner. Then remove the water pipe plugs that were left on the wall during the plumbing renovation.
7. Install the figure-eight valve wrapped with raw tape.
8. Adjust the position of the water heater to make it level.
9. Tighten the screws.
Note: The water pipe slipped down 6 centimeters from the top.
There are two main points to consider: 1) The suspended ceiling will be 2-3 cm below the upper sewer pipe; 2) Space is reserved for disassembling the hot water heater, because when disassembling the hot water heater, it must be pushed upward first. Then it can be removed, leaving 3 centimeters of space when pushing upward.
10. Next, start connecting the pipes. Nowadays, water heaters are installed with PPR pipes. It is very easy to install and the shape is simple and beautiful.
11. Hot melt.
12. Compare them to see how they compare.
13. Installation.
14. The installation is completed.
Notes on electric water heater installation
1. Consumers must ask professional installers to install electric water heaters.
2. Before installation, be sure to check whether the circuit is reliably grounded, and select the appropriate socket and power cord according to the power of the electric water heater.
3. The electric water heater must be installed on a solid wall, preferably in a location that is convenient for maintenance and upkeep.
4. When installing the power socket of the electric water heater, you must consider keeping it as far away from the water heater as possible, preferably more than 2 meters, to prevent water sprayed from the shower from contacting the power socket and causing electric shock.
5. There must be ventilation openings or exhaust fans installed indoors. If installed outdoors, care should be taken to avoid rain.
6. After the installation is completed, be sure to ask the installer to conduct relevant safety inspections and operation demonstrations, and explain how to use it.
