Installation steps of water storage electric water heater
Installation position: ensure that the wall can bear twice the weight of the water heater filled with water, and the fixed parts are installed firmly; Ensure that the water heater has room for maintenance.
Water pipe connection: the water inlet (blue cap) of the water heater is connected with a pressure reducing valve, and the hot water pipe is connected with the water outlet (red cap). Raw material belt should be used at the pipeline joint to prevent water leakage, and the safety valve should not be screwed too tightly to prevent damage. If the water pressure in the inlet pipe is close to the pressure relief value of the safety valve, a pressure relief valve should be installed on the inlet pipe far away from the water heater.
Power supply: ensure that the water heater is reliably grounded. The sockets used must be reliably grounded.
Water filling: after all pipes are connected, turn on the faucet or valve, then turn on hot water to fill the water heater and exhaust until the water from the hot water faucet flows out, indicating that the water is full. Turn off the hot water tap and check all the joints for water leakage. If there is water leakage, empty the water tank, repair the leaking joint and refill the water heater.
Installation height of water storage electric water heater
Generally, those below 100L can be directly hung on the wall (provided that your wall is of good quality). In fact, it's no big deal to hang it, but it must be 2 meters from the ground, and your installation socket should be as far away as possible, and it should be installed in the opposite direction of using the shower to avoid the water splashing on the socket or the protector of the power cord during the use of the water heater. It is best to install a waterproof thing at the socket, because even if water does not directly splash on it, water mist may enter the socket or leakage protector.
Matters needing attention in installation of water storage electric water heater
1. Whether the storage electric water heater is qualified or not is related to the safety of family members. Therefore, when installing the water storage electric water heater, we must invite professional workers to install it. Be sure to ask in detail if you have any questions. The installation point of storage electric water heater needs to be firm, so be careful to sail for ten thousand years. The installation points of storage electric water heater should not be sloppy at all.
2. Ordinary power is relatively high, which requires high-power sockets and wires; If it is a new house that has not been renovated, it can be equipped with special wires in the bathroom. If it is an old house, you can't choose this kind of water heater.
3. When installing the storage electric water heater, the toilet area should be considered, and it should be installed on the load-bearing wall.
4. Suitable for users who only need a single bathroom shower and the kitchen and bathroom are far apart.
5. Generally installed in the bathroom.
6. Pipes should be reserved before the equipment.
Environmental requirements for installation of water storage electric water heater
1, domestic power supply standard
According to the national standard, the power supply of household appliances should be single-phase three-wire 50 Hz 220 V AC. The three wires of power supply-live wire, neutral wire and ground wire-are connected correctly, in line with external identification, well grounded, well insulated, and the wire diameter meets the capacity load requirements. The allowable deviation of power supply voltage in national power quality is-10% to 7%, and it is between 198 volts and 235 volts according to the standard voltage of 220 volts. For electric water heater products, the deviation is correspondingly expanded to-15% to 10%, that is, 187 volts to 242 volts. In areas where the power load is relatively concentrated, it should be appropriately expanded.
2. Protection requirements
The load of household master meter should not exceed the standard. It is better to have an air protection switch or at least a fuse protector, such as a fuse (wire). The nominal value of fuse (wire) should not exceed the limit. The water storage electric water heater should be provided with a separate power supply line, and cannot use the same power line with other high-power appliances (such as Yuba, heater and electric heater) (be careful to connect it from the electric meter, from the wall socket and indirectly). Separate protection devices such as leakage, overload and overcurrent should be provided, and the protection current level should not exceed twice the rated current of a single appliance.
3. Power sockets and extension cords
Electrical appliances should be equipped with power sockets as required. According to the requirements of national standards, single-phase three-wire (hole) socket, the left end of the socket is N pole, connected to the zero line; The right end is the L pole, which is connected with the phase (fire) line; The end with the grounding symbol on the upper end should be grounded and cannot be interchanged. The socket should match the plug of the electric water heater, preferably 16 amp, especially when the rated power consumption of the electric water heater exceeds 2000 watts. It is best to use a waterproof socket with a shell protection to prevent water and steam from entering the connection gap between the plug and the socket. Sockets should be placed as vertically as possible. If it is installed on a wall or other objects, it should be as far away from water sources or shower heads as possible. It is best for bathers not to touch water directly, and to spray water during bathing. The socket should be connected conveniently and firmly to prevent electric sparks caused by poor connection when pulling or touching the power cord. When the power cord is long, it should be bound, pasted and fixed on an immovable object.
4. The power supply wiring should not be too thin.
The power should be more than 50% of the rated maximum power consumption of the electrical appliance, and the cross-sectional area of the power cord should be ≥ 1 mm2 when the current is 6 amps ~ 10 amps (power 1320 watts ~ 2200 watts). If the current is between 10 amp and 16 amp (power is between 2200 watts and 3520 watts), the cross-sectional area of the power cord shall be ≥1.5mm2; If the current is 16 A ~ 25 A (power is 3520 W ~ 5500 W), the cross-sectional area of the power cord should be ≥2.5 mm2. The wire sheath should be waterproof and wear-resistant, and the wire ends and connectors should be fully connected. After a long time of use, it can be judged simply by holding it without a sense of temperature.
5. Consumers are not allowed to connect the power cord themselves.
Installation and maintenance professionals cannot connect or change the power cord themselves. The change and connection of power cord must be carried out by trained professionals with electrician certificate. Electrician work is a special type of work and must be certified.
There are many kinds and brands of water heaters on the market now. The water heater installed in this paper is a storage electric water heater. This kind of water heater is very suitable for home use. It can not only heat cold water, but also store heated hot water to keep the water warm, so that people who are tired for a day can take a hot bath immediately. If you also want to buy a water storage electric water heater and just want to install it yourself, please take a look at the installation method described above, and I believe you can do it too.
The above is about the installation of water storage electric water heater, I hope it will help everyone! ?
