For many citizens, summer is not a particularly comfortable time of the year, as it is often accompanied by blackouts. Yes, and that there is a city, when you also want to live in the countryside with all possible comfort. In order not to depend on the whims of housing and communal services, it is best to pay attention to instantaneous water heaters: feedback from more than one user about them was only positive, so it makes sense to know a little more about them.
When choosing and buying, you need to consider a lot of subtleties. So, the 3 kW models, which are popular because of their cheapness, in reality give out no more than three liters of water per minute, so their use for the shower is extremely inexpedient. In addition, a good
instantaneous water heater in almost all cases will require the purchase of all wiring, since only in newly built houses can there be a normal network that can withstand its operating voltage.
Their main advantage is the fact that at a power of 8 kW or more, water heaters of this type stably give out hot water, regardless of how you open the tap. In addition, when comparing them with storage models, one cannot fail to note the high compactness, which makes it possible to install them even in the smallest rooms without compromising the interior space of the latter. So for a small city apartment, flowing water heaters can be a really good choice. Your feedback in this case will certainly be positive.
Of course, they also have their drawbacks, and one of the most significant should be recognized as the amount of electricity consumed. In addition, when connecting additional consumers, the temperature of the water produced drops sharply. To avoid such consequences, a heater with a power of 8 kW or more is needed. Such a powerful device can only withstand a three-phase electrical network.
So, if possible, it makes sense to choose gas flowing water heaters: the recall of any of their owners contains information that they are much cheaper to maintain. Still, gas is cheaper than electricity, and in terms of fire safety they are much better. As a rule, a model with an output of 18 kW is sufficient for a typical apartment.
Regardless of the power source, they are divided into pressure and non-pressure. By name, you can understand that the devices of the first type are mounted in a water riser, from where water is distributed throughout the apartment. When the faucet is turned on, water is heated automatically (if there is power supply). The cheapest non-pressure instantaneous water heater, the price of which rarely exceeds the mark of five thousand rubles. But at the same time it can often be used only for the shower.
Recall again that you should check the wiring in your home several times. If your apartment is equipped with an old meter and an electric network based on aluminum wire, installing such a heater can even be dangerous in terms of fire safety. In this case, the installation of the storage model will be a much better solution.
So we talked about what flow-through water heaters are for. Your feedback on their use will certainly be positive, but for this you need to follow at least the elementary rules for their application.
