Water heaters for a private house: types and characteristics of water heaters

Many owners of country houses and apartments prefer to use autonomous heating and hot water supply systems, which require a water heater or a double-circuit boiler. The devices differ in many ways, the most important of which is the type of fuel used for operation. A water heating boiler has its own design features and operating principle.

What is a hot water boiler for?

If the housing does not provide for centralized heating and hot water supply, then the implementation of these functions is assigned to the boiler. As a rule, this situation occurs in suburban development. However, heating equipment can be successfully installed in the apartment as well.

With the right choice of technology, the system will effectively perform its task, creating warmth and comfort in the room, regardless of the weather outside the window. Hot water boilers are safe, easy-to-use devices, the heating efficiency of which depends on the specific model and a number of other factors.

Principle of operation

The principle of operation, as well as the device, is quite simple: fuel (wood or coal) heats the air in the pipe, which, rising upwards, heats the water in the heat exchanger. As the water heats up, it rises and flows out through the outlet pipe into the mixer, and then into the shower.

Moreover, to raise the water does not require additional pressure in the system. For the operation of a solid fuel boiler, it is necessary that cold water flows into the tank, which, when heated, displaces the upper layers of hotter water.

Design features

At the moment, several types of water heating equipment are produced, each of which has its own design. Setting the differences between them will allow you to correctly evaluate the technique and choose the appropriate model.

Fire-tube

These types of heaters are equipped with a pressurized gas-tight firebox. For their work, automated burners equipped with blowing fans are used. This feature allows the equipment to work without smoke exhausters, while all the necessary parameters are easily adjustable. As a result, the device is highly efficient and has an efficiency level of 92–95%.

Almost all fire tube boilers are equipped with a cylindrical furnace and smoke tubes inside. Depending on the layout, two- and three-way models are distinguished. This equipment was used in the 19th century and has undergone many changes since then. These boilers are in demand today because they are easy to use and do not require serious maintenance.

Considering the features of the equipment, first of all, it is worth noting that fire-tube boilers can be attributed to gas appliances. On their surface, special pipes are installed along which the coolant moves.

Fire tube boilers are of two types:

1. Steam. The heating medium is heated by means of steam, therefore the inside of the boiler is equipped with a special container.
2. Hot water. With the help of the liquid, the entire body is heated.

The principle of operation is as follows: gas or fuel is supplied to the burner located on the front of the body, which is burned. The role of the firebox is assigned to pipes located in the water, where all combustible material is burned.

Despite their relatively compact size, such devices are highly powerful and safe to operate. In addition, they can function in an autonomous mode, but this will require additional purchase of special equipment in the form of a pressure gauge, a water pressure sensor, and so on.

Water tube

In such models, water is heated by passing through metal pipes. The working pipes located outside are heated by the products of fuel combustion. Due to the design features, an increase in the heating surface is allowed, for which a larger number of water pipes are used.

Due to the convection flow in such systems, the movement of water is accelerated, which means that the heat transfer coefficient also increases. The upper limit of the outlet steam temperature reaches +550 ° C.

Water-tube models are more compact than flame-tube models. It is one piece equipment housed in a rugged case. The principle of operation of water tube technology is the natural circulation of water.

Number of contours

At the moment, the market offers a wide variety of heating equipment. First of all, you need to understand for what purpose the boiler is being bought: only for heating or even preparing hot water. To solve the first problem, a single-circuit model is sufficient - they are more affordable and not so intensive in fuel consumption.

To solve the second problem, a two-circuit device should be chosen. These models, in addition to being able to heat water in a flowing way, are additionally equipped with a built-in boiler, the volume of which varies from 150 to 180 liters. Instantaneous heating is optimal if you need to wash dishes or take a shower in the country.

Boiler in a solid fuel boiler

Special attention should be paid to double-circuit solid fuel boilers, in which a boiler for a solid fuel boiler is located as an additional chamber with its own autonomous heating element.

Structurally, it can be either a fully built-in autonomous boiler, but heated from a common combustion chamber, or just a boiler with a special coil. Thanks to the large coil area, the water heats up quickly and evenly.

The second circuit in such heating devices can rightfully be called a solid fuel boiler. The main disadvantage is that it is almost impossible to accurately adjust the constant temperature for such boilers. You will not face such a problem, for example, in gas double-circuit boilers or in electric boilers. For this reason, it is still best to install an electric boiler if it is possible to supply electricity.

Types of water heaters for heating systems

Boilers, i.e. water heaters, are available in a wide range. Some models are capable of preparing hot water for a bath for 20 minutes, while others immediately heat the liquid during its use. Flow devices are preferred by those who don't like to wait.

Gas

As the name implies, such a system runs on gas. These boilers are also called columns, before they were installed in almost every "Khrushchev". This was explained by the low cost of gas during the Soviet era, which was the key advantage of the units.

However, for the full-fledged operation of the gas water heater, it is necessary to equip a chimney through which combustion products are removed from the room. It is because of this that gas models are increasingly being replaced by a modern alternative. However, with proper operation, their efficiency will be higher compared to an electric boiler, due to their high power. For full-fledged operation, the equipment is connected to a central gas system or a cylinder.

There are flow-through and storage models. The former are capable of instantly heating the running water. As a rule, such a device is called a column and is most often found in Russian homes. The storage tank is not provided, since the system is able to prepare any amount of water that is heated by a gas burner.

Accumulative models are practically not used, because they are not relevant if the gas supply is established in the city.As a rule, they are found in places with weak highways or in areas where there is no wiring.

Advantages:

• after turning on the device, the water immediately begins to heat up;
• unlimited hot liquid.

There is only one drawback - to install such equipment, you must obtain a special permit from the gas service. In addition, you will have to contact a specialized company that will install the system.

Solid fuel

A solid fuel boiler is the best solution for a summer cottage or a free-standing autonomous room (bath, sauna). Such systems are installed most often in cases where there are difficulties with the supply of electricity.

Suitable as fuel for boilers:

• coal;
• logs;
• briquettes.

Solid fuel equipment must be connected to the water supply system. Often, columns of this type are equipped with a mixer through which already heated water is supplied. Of course, the scope of their application is rather narrow, but due to its simplicity and efficiency, the equipment is still in demand. Such columns have existed on the heating technology market for about 50 years, and during this period their properties and capabilities have improved significantly.

Equipment advantages:

1. Rapid heating of the liquid. For example, to prepare water for a shower, 15 to 20 minutes and several kilograms of solid fuel are enough. If the tank is large enough, then in 1 hour the boiler will prepare water for a family of 3-4 people.
2. Autonomy. If you make the right choice, then you will not need to depend on electricity or gas.
3. Availability. Compared to similar heating equipment, solid fuel models have a low price.
4. Reliability. It is explained by the simple technology of the system, which is able to work reliably for many years.

Along with the advantages, solid fuel devices also have disadvantages.

There are such disadvantages:

1. Fuel storage space required. For the most efficient combustion, certain requirements must be met.
2. Inconvenience of cheap models. Such devices cause a lot of hassle during operation. They become more dirty, so they have to be cleaned more often so that their efficiency does not drop.
3. Manual fuel loading. The amount of fuel loaded may vary depending on the model selected.
4. Installation of assistive devices will be required. At a minimum, the unit will need a heat accumulator.

If we consider the principle of operation of a solid fuel boiler, it can be compared to a large wood-fired samovar. In the lower part there is a firebox, waste from the combustion processes is discharged through the chimney. The coolant in contact with the exhaust gases heats up. The design of the models may vary, therefore, the rate of water preparation is also different.

Liquid fuel

Many homeowners use diesel as an energy source. Most often, this equipment is chosen if there is no gas pipeline in the area of ​​residence, and the installation and use of electrical equipment will be very costly. With the help of liquid fuel units, it is possible to heat rooms with an area of ​​100 m2 or more. Often, devices are found in industrial facilities: factories, warehouses, and so on.

Advantages of diesel-powered models:

• high efficiency reaching 92%;
• convenient operation due to excellent automation;
• frequent maintenance is not required;
• for installation and start-up, you do not need a large number of permits and documents.

Many boilers operating on diesel fuel are able to take air directly from the street, for which they are equipped with a coaxial pipe. This means that you do not have to make a chimney, which can also be attributed to the advantages.

Such equipment cannot be called completely autonomous, since a diesel burner operates on electricity.And if difficulties arise with the supply of electricity, then you will need to install a generator. In addition, you will have to prepare a place for storing containers with fuel. For this purpose, fire-prevention measures are carried out, a high-quality ventilation system is equipped.

The principle of operation is as follows: the coolant moves through the pipes of the boiler, which can pass naturally or with the help of a circulation pump. Diesel fuel with air is supplied to the burner under pressure. This mixture is ignited in the combustion chamber.

Electric boilers

Based on the name, it becomes clear that such systems need electricity to heat water. These are the most common models that are often found in apartment buildings.

Advantages:

• in many regions, electricity is more affordable than gas;
• works from a 220 V network;
• no unnecessary pressure is created in the water supply;
• hot water can be supplied to several points at the same time;
• regulation of the temperature of the liquid allows you to set the extreme value, after which the fuse is activated;
• affordable cost.

In a word, if serious requirements are not imposed on the boiler, then the electrical model will be optimal. Such equipment has its drawbacks.

Among the disadvantages are:

• it takes time to heat the water;
• the electricity bill increases.

The key feature of the electric boiler is that it can be installed in any room where there is a network with a voltage of 220 V. This can be: an apartment, a country house, an office, a store, and so on. In addition, you do not need to obtain permits for their installation. In the course of work, carbon monoxide is not emitted, so you do not have to make a chimney.

Where can you apply?

Wood fired boiler

A wood-fired water heater is used to heat the water. It can be used for domestic purposes - for taking a shower and bath, for the kitchen. Some models have the ability to connect to the heating system of a country house, which will save on the boiler.

Such a column is not suitable for buildings that use a centralized city water supply as a source of water. The water heater can only be connected to a system where the pressure does not exceed 0.1 atmospheres.

If there is no running water on the territory of your summer cottage, you can use models that are equipped with a water tank.

It is installed on top of the main structure. The principle of operation resembles a conventional boiler, which uses solid fuel as an energy source.

Classification of boilers by purpose

Not only residential buildings and apartments, but also industrial facilities need high-quality heating. Manufacturers provide for this fact and produce powerful installations, with the help of which large areas are easily heated. At the moment, there are 2 categories of boilers: domestic and industrial.

Household

This is the name of the heating equipment installed in apartments, cottages and summer cottages. For small heated areas, these devices are ideal, but for the conditions of the enterprise, their capacity will not be enough. There are no special requirements for them, the operation is simple and does not imply the presence of special skills.

Thus, household boilers are used for heating and hot water supply of individual houses. It can also be objects of public utility and household use.

Industrial

Nowadays, all enterprises producing heat energy have industrial equipment installed. We are talking about gas, steam and solid fuel boilers, which are fully automated, safe and functional at the same time.

An industrial boiler used for space heating and hot water supply has many advantages.

The following advantages of use are highlighted:

• ease of maintenance;
• the ability to work from several types of fuel;
• adjustment depending on weather conditions;
• upon request, the equipment can be built into a block-modular boiler room.

To regulate the operation of such systems, instrumentation and built-in automatic mechanisms are used, which makes the units safe and reliable. For the manufacture of the outer shell of the boilers, strong steel or cast iron is taken, and they are delivered to the enterprise in the most complete form, which facilitates the installation work.

The most demanded boilers in the industry are gas boilers. The fact is that this type of fuel is now the most accessible resource and, when burned, releases the most heat.

Schemes and connection features

There are two principles for connecting an indirect heating boiler: with and without hot water heating priority. With priority heating, if necessary, the entire heating medium is pumped through the boiler heat exchanger. Heating takes a little time. As soon as the temperature reaches the set one (controlled by a sensor, thermostatic valve or thermostat), all the flow is directed back to the radiators.

In schemes without water heating priority, only a certain part of the coolant flow is directed to indirect water heating. This leads to the fact that the water is heated for a long time.

Scheme without priority

When connecting an indirect heating boiler, it is better to choose a scheme with a priority - it provides hot water in the required amount. At the same time, heating does not suffer much - 20-40 minutes are usually enough to heat the entire volume of water, and 3-8 minutes to maintain the temperature at a flow rate in general. During such a time, no house can cool down enough to feel it. But this is provided that the capacity of the boiler is comparable to the capacity of the boiler. Ideally, the boiler is more efficient, with a margin of 25-30%.

Types of boilers by heating and installation method

Modern boiler equipment can be classified according to many criteria. One of them is a method of heating the heat carrier.

There are 3 types of boilers:

1. Heating elements. They are equipped with tubular electric heating elements.
2. Electrode (ionic, electrolysis). If an alternating voltage passes through the coolant, it will begin to heat up. For this, fuel with certain characteristics is used.
3. Induction. Their action is determined by the properties of ferromagnets, which are heated under the influence of an induction current.

Depending on the manufacturer and the specific model, each boiler has unique features, strengths and weaknesses. It is also customary to classify hot water boilers according to the method of installation.

Floor standing

Such units are installed in large rooms. Due to their significant weight, they are not allowed to be mounted on the wall. They often require their own foundation. The burners of such boilers are atmospheric and pressurized. The former are simpler, cheaper and quieter. The latter are more expensive, but their efficiency will also be higher. Any boiler is equipped with an atmospheric burner, but a supercharged one will have to be purchased.

Advantages:

• durable heat exchanger;
• if desired, heating systems with a large number of circuits are created;
• the possibility of increasing the power.

Along with the advantages, such equipment also has disadvantages.

Disadvantages:

• high price;
• large mass;
• the boiler must be installed in a separate room;
• restrictions on the use of coaxial chimneys.

Due to its high power, the unit effectively copes with the main task - heating a large industrial room.

Wall mounted

These models, in terms of their capacity, are ideal for heating rooms from 100 to 350 m2. They are compact units that are easy to install and attractive in design. Waste gases are discharged in two ways: through a chimney or a special coaxial pipe.The second method is forced due to the built-in fan and is therefore more efficient.

Advantages:

• compactness;
• installed in almost any room;
• availability;
• a coaxial chimney can be installed.

As for the disadvantages, there are only 2 of them: wall-mounted devices are not as powerful and reliable as compared to floor-standing ones.

Wall-mounted devices can have piezo ignition, for which a special button or an automatic electronic mechanism is provided. In a word, in the first case, the start is manual, and in the second - automatic, the main thing is that there are no problems with the supply of electricity.

Tying a solid fuel boiler and a buffer tank

The simplest will be a piping scheme containing a buffer tank with a pre-installed DHW coil. The advantage of this option will be significant savings in space in the boiler room due to the absence of a separate boiler. Another additional plus is a modest investment savings due to the absence of the need to buy and install another node. In this case, the process of maintaining the system is simplified, since there will be no problems with the fight against bacteria.

In summer, a heat accumulator with a DHW coil becomes a full-fledged indirect heating boiler. The pump is connected to the circuit with a standard inch pipe; a pipe ¾ or inch is well suited for an electric boiler. If it is planned to install a buffer tank with a volume of at least 1000 liters, then it turns out to be more economical and expedient to raise the return flow from the electric boiler a little and connect the main circuit not from below, but above, to the middle terminals of the heat accumulator. With such a scheme, the boiler will not constantly heat up the entire volume, which will reduce the rate of its depreciation. This parameter depends on the terms of reference.

If it is required to tie not a solid fuel, but a gas boiler, then the same circuit diagram is used as for an electric one. It should be noted that in the scheme we are considering, a standard electric boiler already contains everything you need:

• pump;
• pressure meter;
• safety valve.

When choosing a model in which these parts are absent, the boiler will have to be properly strapped.

Review of popular models

Any manufactured boiler meets all safety standards. However, more expensive models are equipped with a complex multistage diagnostic system and effective protective automation. The durability and reliability in general depend on how high-quality parts were used in the assembly of the unit. The most popular models according to consumer reviews and expert opinion are as follows.

Installation features

First of all, you need to choose a frost-free room. The place of installation is coordinated with the controlling services. When buying a device, it is imperative to require a certificate from the seller, the presence of which will facilitate registration and obtaining permission for installation.

When choosing a place, you immediately need to think about how the combustion products will be discharged. You can install separate pipes or use a ready-made chimney. As a rule, heating equipment is already equipped with a discharge system. During installation, special care should be taken when connecting the device to the gas supply system.

The general requirements are as follows:

1. It is allowed to install boilers only on load-bearing or solid walls.
2. The hood and chimney are of the same dimensions.
3. The system has free access, which is necessary for maintenance.
4. If the boiler is installed in a cabinet, leave 5 cm free up to the top. It is also important to retain access to the installation nodes.

When self-installation, you need to make sure that the parameters of the equipment correspond to the capacity of the heating system. If the wall-mounted device is connected to the "old" wiring, cleaning and flushing of all pipes will be required, which will exclude further clogging.

The installation process itself consists of the following steps:

1. During installation, a special cardboard template is used, which will help to make fasteners and holes for the chimney.
2. Taking into account the free space for technological maintenance of the boiler, a template is attached to the wall. Previously, the places of fasteners and connections of wires are applied to it. These marks must be transferred to the wall using a marker or colored pencil. The template can then be removed.
3. Next, the holes for the dowels are prepared using a drill of the appropriate diameter. Metal corners are inserted into them. It is important to choose the right dowels, taking into account the material and wall thickness.
4. The top cover (front panel) is removed from the boiler. Thus, the device is easier to hang on the prepared mounts.
5. Before installing the brackets, the correct dimensions of the chimney fittings are checked.
6. Brackets are securely fastened.

Please note that each wall has its own way of installing the mounts. This is explained by the performance characteristics of the materials, meaning the load that the partition can withstand. Electric heating convectors with wall thermostat you will find the answer here.

How to choose a wood-fired water heater

The home appliance market is saturated with a variety of proposals. It is not surprising that a person who first decided to purchase a solid fuel water heater may be confused by the number of models. All of them differ in the quality of materials used in the manufacture, power and characteristics.

The greatest respect among consumers and professionals is enjoyed by Russian, Czech and Bulgarian manufacturing companies. The rest of the brands cause much less confidence, because the build quality of the device leaves much to be desired. Moreover, handicrafts made in clandestine factories are seeping into the market.Units that have not passed testing end up in the homes of gullible buyers, leading to unpleasant consequences.

How to distinguish a factory model from a fake one? Everything is very simple. When buying, you need:

• pay attention to the welding seams - if they are made carelessly, poorly cleaned and do not inspire confidence, it is better to refuse to buy;
• all handles, covers, removable panels and detachable parts must hold firmly in their grooves, do not raise doubts about reliability, lie easily in the hand and be accessible;
• always check the availability of documents for the submitted sample - technical passport, operating instructions and warranty card - this is a list of required papers.

Only if all the described requirements are met, it is possible to purchase a water heater without a doubt.

A wood-fired water heater is an excellent solution for houses that are not connected to central communications. Be careful when buying, and the device will serve you for many years.

Advantages and disadvantages

This type of heating has a significant list of advantages, in the first place of which is the economy of the heating option, which is caused not only by the lowest prices for wood fuel, but also by the low costs of installation and operation of heating equipment.

The main advantages of wood-fired boilers:

1. Environmental Safety. Due to low emissions of harmful substances into the atmosphere.
2. The technological simplicity of the wood-fired and coal-fired boiler guarantees a long period of operation.
3. The variability of the stove device, the possibility of using all types of solid fuels, for any premises, for example, for a wood-fired sauna.
4. Energy independence.
5. The possibility of heating large areas of 1000-1500 m2.
6. A wide range of types of units with a water circuit.
7. The ability to carry out a water heating scheme with your own hands.

Disadvantages of solid fuel boilers:

1. The need for additional storage space for fuel.
2. Low levels of comfort and the need for constant care.
3. High download frequency.
4. Low level of automation and regulation.

Main settings

• storage tank volume. Depending on your needs, you can choose a heater of a certain size. The larger the tank, the longer the water heats up;
• liquid heating time. Depends on the volume of the combustion chamber and the storage tank;
• body material. High-quality metals are used, on the inner and outer surfaces of which an anti-corrosion coating is applied;
• temperature of the liquid inside the boiler. Can be controlled by an electrical regulator, if available. Maximum temperature - 90-95 ° С;
• installation dimensions. The more compact the unit is, the easier it is to install it inside the house.

Varieties of solid fuel boilers

Also, when choosing a speaker, pay attention to the model package. For maximum convenience and functionality, each unit should be equipped with a shower, a special mixer, and a hose. Models that have electric heating elements to maintain optimal temperature are quite popular.

Solid fuel and gas boilers in combination with a buffer tank

Varieties of boilers A modern water heater, which runs on solid fuel, can have different configurations, which affects its function and operating characteristics.

There are such types of wood-fired boilers:

• titanium, where the liquid is heated using a built-in firebox;
• units where the fuel chamber is located separately from the water tank;
• combined designs with an electric temperature controller and heating element.

There are also special solid fuel devices for pool heating.

Water heater to the country

The device consists of a 90-liter water tank and a firebox. Thanks to the installed mixer with shower, you can comfortably use hot water heated from the heat of the firebox.

Cast iron furnaces are considered the most durable and reliable. Cast iron increases the efficiency of the stove, protects it from burning out, retains heat for a long time and maintains an elevated water temperature.

The tanks are made of painted steel with a stainless steel bottom or completely stainless steel. To protect the tank from corrosion and to soften water, 5 magnesium anodes are provided in the design of the tanks.
