Residents of apartment buildings know firsthand what interruptions in hot water are. An excellent solution is the installation of individual heating. But how to choose a boiler in an apartment, because today there are many models that work according to different principles. It is necessary to understand the principles of work, as well as take into account the desires and capabilities of the owner.
Types of heaters
Water heaters for an apartment come in several options:
- indirect heating (also can be attributed to the second group).
Externally, all devices are similar. They are made in a rectangular or cylindrical shape. On the front side there is a temperature indicator, and in some and a knob for its adjustment. In appearance, storage heaters are of impressive size, especially if the model holds 80 liters or more. Flowing, on the contrary, look more modest. To choose the appropriate option, you must first get acquainted with each type of heating devices in more detail.
An instantaneous water heater is a small device that can quickly raise the temperature of a liquid without volume limitation. This performance is directly related to its principle of operation.
Cold water enters the unit, passes through the heating element in the form of a flask, which allows it to be heated up to 60 degrees. Such an almost instantaneous effect can be achieved due to the power of the internal installation, located in a small building. Devices perfectly cope with the task when working for only one draw-off point. Otherwise, the liquid will not be able to warm up to the desired temperature.
Equipment requires careful and frequent maintenance. This guarantees its trouble-free use for several years. In this regard, flow models are an excellent solution for short-term absence of hot water.
What to pay attention to?
The most important indicator for this type of water heater is power. It diverges in the range from 3 to 27 kW. And such installations often require a separate connection from the electrical unit. So, for example, models offering from 3 to 8 kW can be connected to an ordinary 220V outlet. But for more powerful units, you need to use a dedicated 380V line.
It is also important to pay attention to such an indicator as the volume of hot water produced in one minute. Simple equipment consuming 3 to 8 kW can heat 2 to 6 liters, respectively. In this case, the time does not exceed 20 seconds. For personal hygiene and simple household needs, this amount is quite enough. Deciding which boiler to install should be based on the number of people living in the apartment and their needs.
In addition, before choosing a unit, it is advisable to familiarize yourself with the popularity rating among the population. It is he who points to manufacturers offering goods with an optimal price / quality ratio.
Types of installation
Such units differ in the types of installation:
The first are built into the pipeline. This allows you to alternately carry out household procedures. They are most often used in apartment buildings. The latter are built in close proximity to the draw-off point. This makes them attractive for mounting in small country houses.
One of the main disadvantages of such equipment can be safely called a large power consumption. To minimize costs, you have to use hot water sparingly. Those who are not ready to limit themselves in this matter pay attention to cumulative models.
Storage water heaters are considered more convenient to use. They can be of different volumes — from 10 to 500 liters. For apartments, they mainly choose models up to the mark of 150 — it all depends on the number of people living and their needs. Compared to flow-through units, such units take up more space. They can be installed on the floor or wall — depending on the model. Despite this, this equipment option is able to almost always provide users with a sufficient amount of hot water.
Such devices are a cone-shaped or cubic tank with good thermal insulation. A heating element is installed inside, with the help of which the liquid is heated in the range from 35 to 85 degrees. At the same time, it cools down for several days. As soon as the temperature drops, the automation of the unit automatically switches to heating. Then it turns off again. This allows you to save electricity. To maintain the set temperature, a thermostat is installed inside.
Also on individual models you can find some or all additional functions at once:
- accelerated heating;
- antibacterial coating on the inside;
- control system in automatic or manual mode.
It should be noted that such installations provide hot water to all active water points at once. The use of large tanks allows you to simultaneously not only wash the dishes, but even take a bath.
What to pay attention to?
So, how to choose a storage boiler for an apartment? The first thing you need to pay attention to is volume. It is about him that buyers mostly think for a long time. After all, it is important to calculate in such a way as to satisfy the needs of all family members and not experience shortages. At the same time, no one wants to force the unit to work in vain, because this is still an extra cost of energy.
It is important to remember that it takes more time to heat up a large tank. So, for example, you can raise the temperature to 45 degrees water in a 10-liter tank in just 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, you need to calculate it per person and multiply it by the number of individuals in the family. The tank can be 10% more or less than the resulting figure.
In addition, you need to think over the installation site in advance, because usually such containers are mounted in a bathroom or toilet. To save space, you can opt for models that are placed horizontally. They are installed under the ceiling, where they do not interfere with anyone. There are many models of various designs on the market, allowing you to choose the most suitable for the interior.
Types of installation
Units whose volume does not exceed 150 liters are usually placed on the walls. For this, special brackets are provided on the case. Hooks are mounted on a vertical surface, on which the apparatus is suspended. In no case should models intended for horizontal placement be hung vertically and vice versa. Heaters with a volume exceeding 150 liters are placed on a hard surface. In this case, additional fasteners are not provided. Flexible hoses are used to connect to the pipeline.
Indirect heating systems are units in which the temperature of the domestic water is increased by connected heating. It can be an autonomous heating system — a gas or electric boiler. Sometimes a central heating system is connected to such a device.
The device is a tank (as well as storage), only inside it there is a spiral coil through which the coolant flows. This is what heats up the water. Such systems are rarely used in apartments.
Despite this, many people want to know how to choose an indirect heating boiler, because they already have a heating boiler at home. So, the first thing you need to pay attention to is the internal tank. It is desirable that it be made of stainless steel — such a water heater will last a long time. Unfortunately, these units are more expensive than others. In addition, as in the case of storage devices, you need to decide on the volume.
It is important to remember that such systems require additional financial investments at the time of installation, but in the future they will definitely pay off, because the owner will absolutely not have to pay for electricity, which is consumed when using flow and storage models.
There are several main types of water heaters installed in apartment buildings on the market. Each of them has its own positive and negative sides. The main thing is to approach the issue of choice seriously and calculate in detail all the nuances.
