Boilers for water: an overview of the best offers on the modern market

Comfortable conditions imply constant access to hot water, which, unfortunately, cannot always be provided by the city water supply service. In order to solve this problem, water boilers were invented, which are very popular today and are widely used in residential buildings. Let's consider how storage water heaters function, and which models have proven themselves best on the market.

Boilers for water: how storage water heaters are arranged

The very first water heaters were invented many centuries ago, and then steam was used to heat water. Today, the water in the tank is heated by the operation of an external or external heater. The most popular solution today is to buy a hot water boiler with a heating element, capable of ensuring an uninterrupted supply of water at any time of the day.

Finding the right device is not difficult if you take into account all the available data and conditions to which you have to connect. Everyone can independently choose the best model, having at least briefly familiarized themselves with the basic principles of operation and parameters of various devices.

The first thing you need to decide when choosing a boiler is how much liquid you will need for one day. It depends on the purpose for which the heated water will be used, as well as how many people live in the house.

The principle of operation of this device is quite simple and lies in the fact that the warm liquid does not mix with the cold one in the tank, but is gradually displaced by the cold one to the point of intake. At this time, the cold water entering the container is heated as a result of contact with the heating element.At the same time, in the process of supplying water, hot water is necessarily diluted with cold in a ratio of 1: 2, which allows you to significantly increase the useful volume of water.

Speaking about the main components of a hot water boiler, it is worth highlighting:

• storage tank, with a volume of 30 to 150 liters;
• the outer part of the body, which prevents external damage to the structure;
• TEN - a steel heating element, which consists of a tube or nichrome spiral and converts the received electrical energy into thermal energy;
• thermostat - a device that is responsible for adjusting the water temperature and maintaining a certain temperature regime inside the tank;
• magnesium anode - an element that prevents corrosion on the inner walls of the container. It "glues" all small damages and cracks on the surface of the walls.

In such a system, each of the elements performs its important role and the service life of the boiler depends on how high the quality of each of these parts is. Therefore, when thinking about how to choose an electric water boiler, you should pay attention to each material and element that was used in a particular device.

What can be an electric boiler for heating water

If you want to buy an electric water boiler, you should also think in advance about what form of device is preferable for your bathroom. In most cases, these containers are cylindrical or flat rectangular structures. But depending on how they are oriented, the division is made into 3 groups:

• vertical;
• horizontal;
• universal.

How an electric hot water boiler should be positioned depends on how the heating element is positioned inside. In order for the device to function normally and provide natural convection of the liquid, the heating element itself must be fixed in the lower part of the tank. Simply put, you can't just turn the boiler over at your discretion and you need to place it strictly as the manufacturer recommends to do it. The only exception is universal models that can work in any position.

In addition, the devices differ depending on the power. So, for example, to connect a low-power boiler (up to 12 kW), a single-phase power source will be enough, while a more powerful device will need a three-phase one.

Important! Although such a measure is rarely used, it is still worth knowing that to install a water heater with a capacity of more than 6 kW, you will need to lay a separate power line, as well as a separate machine and an RCD.

Gas boiler for heating water: what is it?

A gas boiler is a separate type of water heating structures, the use of which is permissible only in private houses. This limitation is easily explained by the need to lay a chimney, as well as a gas supply to power the boiler.

But even if you want to install a gas boiler in your own home, in order to do this, you will need a special permit, which can only be obtained from a specialized service that deals with these issues. It is strictly forbidden to carry out such repair work without the approval of the special service, as this can provoke a dangerous situation.

So, if the appropriate permit is still available, the first thing to start with installing a gas boiler is the chimney.If it is not there, then you will have to carry out all the work on its installation, and if it is available, then the boiler is located strictly in the place where there is a chimney.

The main advantage of such a seemingly complicated solution is economy. Yes, such a unit costs an order of magnitude higher than an electric one, but its operation will be much cheaper, which will not only cover the extra purchase costs, but also spend less money on payment in the future. Another positive aspect is that a gas boiler heats up a liquid much faster than an electric one.

How does a flow-through heating electric boiler for water differ from a storage boiler?

Flow-through heaters are used along with storage heaters, and in certain situations they can be more convenient. So, they have the following advantages:

• less weight and size, which allows installation in more limited space;
• the amount of water that they are able to heat up is not limited by anything;
• the water temperature is not maintained, which means that resource costs are reduced.

But flow-through systems are far from perfect, because often, before getting warm water, it is necessary to drain hot or, conversely, boiling water may pour out when the tap is opened. This is because the temperature does not adjust immediately. Another negative point is that a change in pressure affects the temperature of the water.

Another important aspect is that in order to install a modern flow column, you will need reliable electrical wiring equipped with special fuses. And for the most powerful models, a three-phase power grid is needed at all.

Numerous reviews claim that buying a water boiler is a much more practical solution as it is associated with less hassle to operate.

Criteria for choosing a storage electric boiler for heating water

The price of a water boiler, as well as its efficiency, are two main criteria that buyers rely on when choosing a device. But in fact, there are several more important aspects, and in order not to get lost in the wide range of the modern market, it is worth paying attention to several more aspects.

Despite the fact that the set of elements for all devices is the same, even models that are very similar in external parameters can significantly differ from each other in characteristics. For example, the outer casing can be made of stainless or enamelled steel, while other models use polymer materials.

It is believed that models made of carbon steel or copper are significantly more stable and significantly exceed plastic ones in terms of service life. In addition, they are able to ensure the simultaneous use of several points of water intake, in contrast to plastic, for which the maximum allowable number of points of water intake is one.

For the manufacture of the inner tank, a material such as glass porcelain or simply stainless steel is used. The first option is distinguished by its chemical neutrality, which allows the water to always remain very clean. But such a coating reacts negatively to temperature changes and tends to crack during operation.

Interesting! Boilers, in which glass porcelain was used as a coating on the inner surface, are much cheaper, but this is due to their short operating life, which is limited to only 3 years.

If you want to buy a really high-quality boiler with a good inner coating, then you should pay attention to the titanium-coated stainless steel models. They are characterized by resistance to corrosion and, despite the rather high price, are quite justified, since their service life is 7-10 years.

Another important aspect that you definitely need to pay attention to before buying a boiler for heating water is a heating element. The main enemy of any heating element is scale, which settles on its surface due to the fact that the water is too hard. To extend the life of such a device, regular cleaning of all elements that come into contact with water will be required. Although, as an alternative, you can purchase a boiler with a dry heating element. This design provides a special protective flask for the heating element.

Rules for draining water from a boiler: how to do it yourself

One of the most common questions that sooner or later arise from everyone who bought a storage water heater is how to drain the water from the boiler without resorting to the help of specialists. It's actually pretty easy to do.

But in what cases may such a procedure be required? Here are some good reasons to start draining the boiler immediately:

• the air temperature in the room dropped below + 5 ° С. This is fraught with freezing of water directly in the pipes, which can lead to serious damage;
• there is a need to clean the inside of the tank. Usually it is carried out 1-2 times a year, depending on the quality of the water in the pipeline.

The first thing you need to know is that you need to drain the water from the boiler carefully, without leaving any liquid residues in the container.

Helpful advice! In the recommendations for the operation of some devices, manufacturers indicate that about once a month it is necessary to partially drain the water from the tank in order to remove limescale.

In general, how exactly the water is drained from the container, each manufacturer indicates individually for their products, so the first thing to do is read the instructions for use. Then you need to disconnect it from the network and you can start disassembling in the way indicated by the manufacturer.

To make this procedure as safe and fast as possible, it is worthwhile to pay attention to several aspects again before draining the water:

• the device must be disconnected from the network;
• the water supply tap is closed;
• the water in the tank is cold and does not pose any threat;
• water from the boiler will not spill onto the floor.

How to drain water from a boiler: video instructions and subtleties of the procedure

To understand exactly how the procedure for draining the liquid occurs, it is useful to read the instructions, as well as watch the video. For example, having understood how to drain the water from the Ariston boiler, you can cope with many devices of a similar design.
