К благам цивилизации (лифт, горячее water supply, sewage, central heating) people get used quickly. But what if, due to some circumstances, there are problems with hot water in the house? In this case, it is desirable to purchase instantaneous water heater on the faucet.
Water heating in such a device occurs when itflowing through a small container in which there is a compact but powerful electric heater. The advantage of this device is that electricity is consumed only during its operation. The main characteristic that the instantaneous water heater on the faucet has is its performance, i.e. how much he will be able to give the water of a certain temperature for a specific period of time. It is measured in l / min (liters per minute). Naturally, the performance of this device is directly proportional to the initial temperature of the water flow at the inlet (which can vary from 5 to 20
aboutC) and the power of the heating element.The flowing electric water heater on the crane heats water literally instantly. That, how much it should be warm, regulate pressure change. The standard model usually includes two knobs: to control the flow rate and set the desired temperature.
Depending on the power, these devices are dividedon several classes of energy consumption. Instantaneous water heater-nozzle on the crane, having a power of 3.5 kW or less, is the least functional option. It is usually set only when the water inlet temperature is not below 18aboutWITH.More powerful options (the most common - 5 kW, less often - 7 kW) can cope with the flow even the coldest, and therefore they can be used year-round. By the way, on some models there is an electronic display that displays the current temperature.
What is the flow water heater on the faucet?
The structure includes:
- A heating element. Usually it is a tubular electric heater (heater), made of copper or steel.
- Pressure switch. Does not allow the heating element to turn on in the absence of water.
- Thermal sensor. When overheating is triggered off.
- Flow switch. It supplies power to the heating element when liquid flows through it.
- Power switch
- Crane nozzle - spout. The presence of holes and a smaller cross-sectional diameter of the spout at the outlet creates additional resistance to water, which makes it possible to use the heating element more efficiently.
Any instantaneous water heater on the faucet has the following features:
- Compact size, which greatly facilitates the installation of the device, its connection and further operation.
- Local area of use. It is usually installed on only one connection point.
- Low sensitivity to the quality of water containing a small amount of salts.
- The big power consumption and, respectively, a big expense of the electric power.
What is important to know when installing an instantaneous water heater?
The flowing water heater on the crane iselectrical device of high power, and therefore when installing it is necessary to lay a separate wiring and grounding. It is desirable that a specialist did it. Wiring available in the room must be rated for a current of at least 30 Amps.
