Instantaneous water heater electric faucet bottom connection White

Description
Instantaneous water heater White Bottom connection
ATTENTION!!!
This instantaneous water heater model is designed for BOTTOM connection (pipe from the BOTTOM).
If the water heater is connected in violation of this rule, this is a violation of the operating rules, which will immediately lead to the failure of the water heater. Violation of operating rules is not a warranty case and is not subject to repair or replacement.
Advantages of a 3 kW instantaneous water heater:
Low power consumption (power 3 kW);
Quick water heating in 3-5 seconds (no need to wait for the water to heat up, like in a boiler);
Heating water up to 60 degrees;
Minimizing water consumption;
Low cost of a water heater (for example, a 6 kW water heater or the simplest boiler is 7 or more times more expensive);
Easy installation - you just need to install the faucet and connect the plug to the socket;
Space saving - the tap is installed instead of a stationary tap, you do not need a lot of space as for a boiler;
Now let’s move on to very IMPORTANT points and answers to the main question, why “the faucet does not work or does not work correctly”:
The required water pressure for the water heater to operate is 0.04-0.5 MPa. If the water pressure is lower, the tap simply will not turn on, since there is a fuse in the tap that prevents it from burning out in the absence of water or at low pressure; If the pressure is higher than 0.5 MPa, then the water temperature will be less than 60 degrees, which are declared by the manufacturer;
In order for the water heater to produce 3 kW, the voltage from the network must be 220 V. Often in houses (especially private or old buildings) the voltage is below 220 V, and accordingly the water heating temperature will be lower;
The situation is similar in winter, when the pipes freeze, the water is at a very low temperature, then a 3 kW water heater will not warm the water to 60 degrees, since 3 kW is not a lot of power.
