Instantaneous heating of water in winter and summer, regardless of how public utilities work, is the advantage that a running water heater for an apartment has. The main thing is to choose the right equipment, so that it is convenient for them to use, providing maximum comfort of life.
Since the situations are different, and no one wants to heat the water in the pots, alternative options for obtaining hot water should be considered . A flow-through water heater for an apartment can be an excellent acquisition in this case. And here it is important to know its principle of action, so that the choice is justified. The electric model is a plastic or metal box, which is small in size and fastened to the wall. Such devices operate on the principle of a gas column, that is , they heat water immediately after it comes from the water pipe, and after the shutdown of the crane is stopped. That is, they do not need additional time for preparation, therefore, the user receives an unlimited amount of heated water without delays, as is usually the case with centralized water supply. This is the difference between flow models from storage, capable of heating only a certain volume.
A flow-through water heater for an apartment basically contains a heating element - a heating element consisting of a copper pipe with a pressed nichrome spiral inside. When the electric power is supplied, its heating occurs, as well as the transfer of heat to the surrounding water. The higher the power of the device and the temperature of the cold liquid, the faster it reaches the desired state and becomes hotter at the output. Such heating elements are characterized by a long service life, they are not afraid of air jams. The heater requires a constant flow of water under pressure, since without pressure the heater can burn out over time. It is desirable that a flow-through water heater for the apartment is equipped with a water shut-off sensor, which will allow it to stop working in this case.
Before you make a purchase, you need to determine the purpose of purchasing this device. If it will be used only in the summer, while many water sources will not be turned on at the same time, a 5 kW water heater will work. If it is required that the shower, washing and other points of water intake work simultaneously, a more powerful device is needed. More comfortable conditions can be created by using a heater with a power of at least 8 kW. For those who like to take a hot bath, you need to consider models whose power exceeds 13 kW.
The flow-through water heater is usually not equipped with its own mixer, unlike non-pressure collectors. Usually, they are used for country houses and country houses, since they are immediately equipped with mixers. The apartment does not need such equipment.
