How to choose a geyser: selection guidelines and rating of the best models

Requirements for a standpipe

The production of outdoor speakers is based on state standard number 15150. The main requirements relate to the location of the device, and the number of consumers is also taken into account.

• A column is installed at the location of the water well. If there is no well, it is recommended to build it as close to the sidewalk as possible. The ideal place is a crossroads.
• Consumer coverage is carried out at the rate of one column per area with a radius of 1000 m.
• It is optimal if the street water intake is formed on sandy soils for easy drainage of water into the ground.
• An elevated installation location is better than a low-lying one.
• In winter, it is better to insulate the column, because the metal casing will not be able to protect the water from freezing.
• Installation is carried out on water supply networks in which the pressure does not drop below 1 atm.

All fulfilled requirements guarantee long-term and efficient operation of the device. In this case, the depth of the water pipes must be taken into account. Based on this parameter, the device model is selected.

Design and principle of operation

The design of a street water pump includes a small number of parts. The main one is the ejector. With its help, the water supply is opened and closed:

• pipe riser located inside the housing;
• an ejector consisting of three parts: a neck, a socket and a receiver (sump);
• in the lower part of the device (receiver) there is a cylindrical mesh, the task of which is to filter the water entering the column;
• The speaker body is covered with a metal cover in which the lever is installed.

The column works as follows:

1. when pressing the lever, the pipe riser is lowered;
2. at the end of the latter there is a neck, which is a cylindrical object with a chamfer widened at the end;
3. when the lever is pressed, the latter rests against the socket to prevent the riser from falling;
4. at the end of the riser there is a valve, which is located in the lower part of the column - the settling tank (receiver);
5. the valve closes or opens the receiver opening;
6. when you press the lever, it goes down, opening the hole, that is, water moves;
7. the lower end of the riser rests against a spring, which is located at the lowest point of the sump; it ensures the reverse motion of the entire structure;
8. when the lever is released, the compressed spring expands, raises the riser, and the valve closes the hole in the upper part of the sump.

The design of the column is very simple, so it works effectively for many years. Most often, the spring that is constantly located in the water fails. It began to be made from tool steel, which is not afraid of contact with moisture.

How to choose a geyser

Instantaneous gas water heaters most often have small dimensions; they are an ideal choice for a small apartment. The device is connected directly to the cold water supply system and runs on both natural and liquefied gas.

The principle of operation of the column is very simple: water enters the heat exchanger, where it is heated by the combustion gas, and is immediately supplied to the mixer.

A storage geyser can hold a large amount of liquid, so it requires a lot of space. The heater heats a certain amount of water in the container and maintains the temperature for a long time.

If the water cools down, the column automatically heats it up to the desired temperature. The water container is well insulated, so the water stays hot longer.

Depending on your needs, you can choose a gas water heater with a liquid tank of 50 liters or more.

Basic selection options:

• Power. Depending on how much liquid is heated, a geyser can have a power from 6 to 30 kW.
• Type of ignition - can be automatic or semi-automatic. The automatic type of ignition is triggered when the water supply is turned on or when the water in the container has cooled.

The semi-automatic type of speakers works only if you press the piezo ignition button. Such a device increases gas consumption, since the pilot flame must always be burning.

• Burner type - can be with constant or modulated power. Devices with constant power are less convenient in places where the water pressure and, accordingly, the heating temperature often change.

A burner with modulating power automatically adjusts to the water pressure and maintains the initially set temperature.

• Type of exhaust of combustion products. A chimney column is installed if the corrugated hose can be routed into an existing chimney.

Turbocharged devices are less popular because there is a risk of the outlet paths freezing at low temperatures. In this case, it is necessary to drain the accumulated water frequently to prevent the heat exchanger from exploding.

• Safety – a geyser is a dangerous device, so you need to pay attention to the presence of protective sensors and relays.

Secondary parameters:

1. Dimensions - if this point does not matter, you can select a column, taking into account only the main characteristics and requirements. If the room does not allow you to install a large storage column, you can choose the most compact flow-through one.
2. Shape – if you will hide the device in a kitchen unit, it is better to choose a square shape of the required size.

Types of water taps

Manufacturers offer two types of designs, which are labeled as KV and KVO. In terms of technical characteristics, both devices do not differ from each other. The main difference is the method of attaching the receiver to the device body.

In KV models, fastening is done with two bolts, which are passed through the ears. One is located on the speaker body, the second on the receiver. Gaskets are installed between the two units to ensure the tightness of the structure.

In KVO models, fastening is done using square flanges. One of them is welded to the body, the second to the receiver. This design uses four bolts.

The best geyser for a private home

In terms of versatility, the Bosch WRD 13-2G is considered one of the best due to its fairly high power and performance.

Characteristics:

• This model can be used to supply two water intakes.
• The manufacturer offers the possibility of replacing the burner for liquefied gas.
• Compact parameters, classic shape and color allow you not to hide the water heater without spoiling the overall design of the room.

Pros:

• It has a built-in hydrodynamic generator, thanks to which automatic ignition is carried out.
• The outlet temperature corresponds to the readings on the LCD display.
• When the water pressure changes, the water heater maintains the set temperature.
• The copper heat exchanger prevents heat loss and also significantly extends the service life.

Minuses:

• The lowest pressure this model can operate with is 0.35 bar.
• High price.

Installation features

On the side of the receiver there is a pipe with a diameter of 20 mm with an external M20 pipe thread. A pipe of the same diameter is connected to it, which is removed from the water supply circuit. The connection of the pipe to the water supply is electric welding.

A valve must be installed between the column and the supply pipe. The connection is made using flanges or threads. The first option is simpler in terms of installation and maintenance. The purpose of the valve is to shut off the water supply and regulate its pressure.

Under the column inside the well, be sure to lay a solid foundation on which it will rest. To do this, pour a concrete pad or lay a ready-made reinforced concrete slab.

Before commissioning, the water dispenser is washed with an aqueous solution of bleach. In this way the device is disinfected. The well is closed with a cast-iron sewer hatch.

How to do it yourself?

The location for drilling a well for installing a garden water pump is selected no closer than 30 meters from the sewer or cesspool. At a distance of 15 m from any buildings. It is advisable to focus on soil moisture.

A steel cone is welded to a pipe with holes, a metal mesh is wound and secured. The design looks like a spear.

As the pipe sinks into the ground, the next threaded section is connected using a coupling. In order for the pipe to easily penetrate the soil, the well site is watered with water. To determine whether a pipe has reached an aquifer, water is poured into the pipe. If the water goes down, the pipe has reached the aquifer. If not, drilling continues. To make the well more efficient, you need to bury the pipe below the detected water.

If, when driving, the pipe has reached the top layer, into which wastewater from the so-called perched water enters, it must be driven even deeper. When water starts flowing from the well, a check valve is installed in the pipe and the pump hose is connected. You need to pump water out of the well until it becomes clear.

In order to determine the quality of water, you need to send it for analysis to the SES. The transparency of the water must be at least 30 cm. Hardness, alkalinity, and chlorides must be checked.

When a source of water appears, a water column is installed at the dacha. Installation is approximately the same in a centralized water supply well and in the ground of a well. For a water supply well, two concrete pipes are installed, and for a column in the ground - one. The deeper the pipes are in the ground, the higher the frost resistance of the structure. The recommended pipe depth is 0.75-4 meters.

To prevent the water in the pump from freezing in winter, it must be constantly running, with a flow. Since dachas are rarely visited in winter, usually for the purpose of steaming in a bathhouse, additional measures are taken to ensure that the water source does not freeze in winter. The riser is drained in advance, the walls of the well are insulated, lining the inside with heat-insulating material.

Insulation does not always help in severe frosts, so when installing the column, additional equipment is installed. For example, the so-called Mayevsky crane. It drains water from the riser, thereby preventing freezing. Sellers of this equipment provide drawings with connection diagrams.

Operation and Maintenance

The speakers need to be serviced monthly. Check the ejector for leaks:

• a plug made of wood is driven into the drain pipe located in the upper part of the riser;
• press the lever;
• water fills the entire volume of the speaker body;
• the lever is released, and if the water has not increased in volume within 10-20 minutes, it means that the ejector fits tightly to the hole in the receiver;
• you need to pull out the plug, press the lever again and empty the column housing completely.

If the ejector works correctly, water in a 175 cm long water column will be removed from the housing in 5-6 minutes.

If it is necessary to carry out repair work, first of all it is necessary to close the valve, disconnecting the device itself from the water. Next, the cap with the lever is removed, then the riser, after which you can inspect and repair the parts of the ejector and sump. Often the mesh becomes clogged and simply needs to be replaced with a new one.

Needle well and tube well, features of arrangement and use

Tube well and Abyssinian are varieties of the classic well with differences in the arrangement of the trunk. Instead of rings, a tubular source shaft is formed from steel pipes, and an Abyssinian well is a needle-shaped well made from small-diameter steel pipes. The water intake is drilled to a depth of 15 m. Wells of this type cannot always be installed at the level of aquiferous sand, and groundwater cannot be used as drinking water.

The Abyssinian well is an improved type of tube well. Despite the shallow depth, there is a chance to get fairly clean water: high water and precipitation do not penetrate into the source. One of the main advantages is the low cost of arrangement and ease of implementation. An Abyssinian well can be made without the involvement of specialists.

The Abyssinian needle well can be used to collect drinking water for one home

The depth of the source ranges from 8 to 15 m. The first aquifer layer of sand lies at this depth. The end of the casing pipe is installed at the boundary between the layers of loam and sand. The main difficulty is to find a place where there will definitely be water at a shallow depth. Usually they are guided by the presence and depth of neighboring water intakes. If the areas are located at the same height, there is a high probability that the water layer occupies a large area.

An igloo well is constructed exclusively in soft soils: clay, loam, clay with layers of sand, quicksand. Such wells cannot be drilled in rocky soil: if a needle hits a boulder, all the work will have to be redone.

Small diameter drive pipe is not designed to pass through rocky soil

Water can be used after testing. Usually the quality of the water is acceptable, and if a filter system is installed, it can be used for cooking. The service life of a well does not exceed 10–12 years. The flow rate is subject to seasonal fluctuations, up to 1.5 m3. The amount of water is enough for 1 – 2 water points.

Surface water intakes are plugged using the impact-rope method. When constructing an Abyssinian well, the pipe is simultaneously the lower part of the casing and the drill. A pipe equipped with a needle-shaped tip and a filter is driven into the ground.

Instead of the impact method, a hand drill or MBU is used

After passing to a depth of 150 cm, the next segment is screwed on (or welded). The finished source is equipped with a surface or submersible pump. To install the equipment, a pit is first prepared, which must be thermally insulated.

Seasonal water supply can be organized in the open ground with flexible hoses

Small wells require constant operation. Regular water intake prevents the filter from clogging. Systematic cleaning can extend the life of the source. Preventive cleaning is recommended annually.

Speaker cost

Prices for outdoor water taps for irrigation and other household needs are almost the same from all manufacturers. They depend on the type of design and length of the device.

• HF 275 cm long costs 5,000 rubles;
• KVO 275 cm – 4500 rub.;
• HF 375 cm – 6300 RUR;
• KVO 375 cm – 5700 rub.

Spare parts are sold separately: spring 240 rubles, mesh 170 rubles, valve – 150 rubles, ejector 515 rubles, receiver assembled – 3500 rubles, receiver not assembled – 1500 rubles, cap – 1800 rubles.

Requirements for the distance to the standpipe

In accordance with clause 11.19 SP30.13330, the radius of action of the water intake column should be no more than 100 meters. A blind area 1 meter wide with a slope of 0.1 from the column should be provided around the water intake column.

For the normal functioning of a street water pump, the pressure in the water supply network at the point of its connection must be at least 10 m.

Why does the water column not freeze in winter?

A distinctive feature of the design of an outdoor water pump is to ensure non-freezing in winter (the water in the pump when closed is below the freezing depth of the soil).

It should be noted that the water pump, like the water supply network itself, can still freeze in winter. This depends on the “severity” of winter and the water withdrawal regime.

The best geyser with automatic water temperature control

The domestic gas water heater Neva 4510-M has many advantages, the main one of which is an affordable price.
Characteristics:

• The device is made in a classic style and has no special frills.
• The speaker has compact parameters, so it can be installed in a small apartment or in a private house.
• The column operates quietly and uniformly supplies liquid at the desired temperature even with sudden pressure changes.

Minuses:

• The water heater is not equipped with smooth flame modulation, which will not allow the use of this device at two water supply points.
• The column has a power of 17.9 kW, which allows you to heat only 9 liters per minute.

Device and principle of operation

The quality of water in the standpipe must meet the requirements for drinking water, since water is drawn from the water supply network of the settlement. However, it must be taken into account that if there are violations in the design of the column, groundwater may penetrate into the interior through leaks in the flange connections, which can affect the quality of the water. Therefore, the water obtained at the standpipe should be boiled before drinking.

The figures below illustrate the operating principle of the column. The column consists of the following elements:

1 – handle; 2 – cap; 3 – supply pipe; 4 – body; 5 – camera; 6 – ejector; 7 – receiver; 8 – pipe from the water supply network; 9 – mesh; 10 – spring; 11 – valve with seal; 12 – holes

When the handle (1) of the water dispenser is pressed all the way, the supply tube lowers and moves the ejector (6) down, which leads to the displacement of the valve (11) and compression of the spring (10). Water from the receiver (7) through the formed annular gap between the valve and the body through the holes (12) enters the supply pipe and then to the consumer. The vertical valve stroke is 16-18 mm.

Operating principle of the column: after pressing the handle (1)

After the water withdrawal is completed, the handle (1) is released and it rises along with the entire chain - supply pipe (3), ejector (6) and valve (11) due to the spring (10). As a result, the flow of water is blocked. The supply pipe is emptied into the chamber (5) of the underground part of the column.

The next time the column is used, water from the chamber (5) is carried away by the ejector (6) through the hole in the ejector into the supply pipe (3) and is thereby emptied. This ensures that the dispenser does not freeze in winter.

How the column works

When pressed down all the way, the lever (4) presses through the pipe and the tip of the riser (2) onto the ejector with valve (9), the spring (13) is compressed and the lower part of the ejector (7) with the holes falls below the socket. The water that is constantly in the receiver is filtered through a mesh (11), enters the ejector and then along the riser (2) to the consumer. After the end of water collection, the lever under the action of the spring rises to its original position, the valve with a rubber gasket (10) is pressed against the inner end of the ejector and closes the access of water to the ejector. The water remaining in the riser is drained through the window in the middle part of the ejector (6) into the pipe (1), where it remains until the next water draw. A normally operating ejector ensures complete suction of water during subsequent water withdrawal and guarantees uninterrupted operation of the column.
