Residents of apartment buildings do not know firsthand what the shortages of hot water. Great solution is to install individual heating. But how to choose the boiler in the apartment, because today there are many models, working on different principles. It is necessary to understand the operating principles, as well as take into account the desires and host capabilities.
types of heaters
Water heaters for apartments there are several options:
- flow;
- storage;
- indirect heating (also can be referred to the second group).
According to the external characteristics of all devices are similar. They are made in rectangular or cylindrical form. On the front side there is a temperature gauge, and some pen and its adjustment. On view storage heaters have impressive size, especially if the model puts a 80 liters or more. Flow on the contrary - is more modest. To select a suitable option, you must first get acquainted in detail with every kind of heaters.
flow
Instantaneous water heater - a device of small size, which is capable of quickly raising the temperature of the liquid are not limited in volume. This performance is directly related to its operating principle.
Cold water enters the unit, passes through the heating element in the form of a bulb that allows heat it to 60 degrees. This almost instant effect can be achieved by the power of the internal system is located in a small package. Instruments excellent job when working for only one-WATER OUTLET. Otherwise, the liquid can not warm up to the correct temperature.
Equipment calls for a thorough and frequent maintenance. This ensures its problem-free use for several years. In connection with this flow pattern are an excellent solution by brief absence of hot water.
What to look for?
The most important indicator of this type of water heater is power. It diverges in the range of 3 to 27 kW. And such installations often require separate connections from an electrical node. For example, models offering from 3 to 8 kW, can be connected to an ordinary 220V wall socket. But for the more powerful machines need to use a dedicated line at 380.
It is also important to pay attention to indicators such as the amount of hot water produced per minute. Simple equipment consuming from 3 to 8 kW, can be heated from 2 to 6 liters. When this time does not exceed 20 seconds. Personal hygiene and simple household needs such a number is enough. Decide which to install the boiler, you need to start from the number of people living in the apartment and their needs.
Also, before you choose the unit, it is desirable to get acquainted with a rating of popularity among the population. Just he and indicates the manufacturers, offering products with the best quality / price ratio.
types of installation
Such aggregates different types of plants:
- pressure;
- unconfined.
First built in the pipeline. This allows you to turn everyday spending procedures. They are mostly used in apartment buildings. While the latter are built in close proximity to water points. This makes them attractive for mounting in small country houses.
One of the main disadvantages of such equipment can be considered a great power consumption. To minimize the costs necessary to use hot water sparingly. Those who are not ready to limit myself in this matter, pay attention to the cumulative model.
savings
Easier to use are considered to be just water heaters. They can be different sizes - from 10 to 500 liters. For apartments mainly choose the model to the level of 150 - it all depends on the number of living people and their needs. Compared with flow like aggregates take up more space. They can be mounted on the floor or a wall - depending on the model. In spite of this equipment is capable of such an option is almost always provide users with a sufficient amount of hot water.
Such devices are conical or cubic tank with good thermal insulation. Inside the heater is installed, with which the liquid is heated in the range from 35 to 85 degrees. At the same time it cools down for a few days. As soon as the temperature drops, the unit will automatically shut off equipment for heating. After that, the same is turned off again. This allows the economical use of electricity. To maintain the desired temperature, is installed inside the thermostat.
Also on some models, you can find some or all additional functions:
- rapid heating;
- antibacterial coating the inner side;
- control system in an automated or manual mode.
It should be noted that such units provide hot water immediately all active water points. The use of large tanks can simultaneously not only the dishes, but even to take a bath.
What to look for?
So, how to choose a storage heater for the apartment? The first thing you need to pay attention - the volume. That is about it for a long time mainly reflect customers. After all, it is important to be calculated so as to satisfy the needs of all family members and no shortage. In this case, no one wants to be forced to work the machine is wasted, because it is still unnecessary energy costs.
It is important to remember that more time is needed to heat a large tank. Thus, for example, raise the temperature to 45 degrees water in a 10 liter tank can only 15 minutes. But the volume of 100 liters will be able to warm up in 4 hours.
To calculate at least an approximate volume used, it is necessary to calculate per person and multiply by the number of individuals in the family. The tank can be 10% more or less digits received.
Also, you need to think in advance the installation site, because usually such containers are mounted in the bathroom or toilet. To save space, you can stop the choice on models, which are placed horizontally. They are installed on the ceiling, where no one interfere. In the market there are many models of different designs that you can choose the most suitable for the interior.
types of installation
Units, whose volume is less than 150 liters, usually placed on the walls. To this end, the housing provided special brackets. The vertical surface mounted hooks that are suspended and the device. In no case can not be a model designed for horizontal placement, hang vertically and vice versa. Heaters which exceed 150 liters, placed on a hard surface. In this case, additional fasteners are not provided. For connection to the conduit using flexible hoses.
indirect heating
Indirect heating systems - units, in which the temperature of the water for household purposes is enhanced by the connected heating. This can be a stand-alone heating system - gas or electric boiler. Sometimes it is connected to such a device central heating system.
The device is a tank (and storage), but it is within the helical coil through which the coolant flows. It is due to this and there is water heating. Such systems are rarely used in the apartments.
Despite this, many people want to know how to choose the boiler indirect heating, in fact already have home heating boiler. So the first thing to note - the inner tank. It is desirable that it was made of stainless steel - a water heater will last a long time. Unfortunately, these units are more expensive than others. Furthermore, as in the case of storage devices, it is necessary to determine the volume.
It is important to remember that these systems require additional financial investments at the time of installation, but they sure will pay off in the future, because the owner absolutely do not have to pay for the electricity that is consumed when using the flow and storage models.
On the market there are a few basic types of water heaters installed in apartment buildings. Each of them has its own positive and negative sides. The main approach to the issue of choice seriously and thoroughly calculate all the nuances.
