Parapet boilers: the pros and cons. Types of parapet boilers and their connection

Natural gas today is the most convenient and common type of fuel for use in autonomous heating systems that are installed in private homes. If you compare this resource, for example, with coal, you do not need to worry about regular replenishment of stocks, you only need to connect to a local gas pipeline. Therefore, individual heating systems today are mostly designed for the use of gas.

The need to use parapet boilers

Parapet boilers are one of the most optimal options . They can be used even for heating a city apartment. Initially, such equipment was developed as an alternative to wall-mounted ones, which have a lot of advantages, but are very demanding for operating conditions. For stable operation, they need constant pressure, soft water, high quality gas, as well as uninterrupted power supply. For this reason, such devices often fail and require regular maintenance. Over time, they were replaced by parapet boilers. They do not assume such stringent operational requirements and are able to ensure a stable operation of the heating system. The described installations are heating energy-dependent units that are intended for installation in apartments and private houses, combining all the positive characteristics of convectors and gas boilers.

Connection Features

Parapet boilers have a closed combustion chamber that does not communicate with the room. The equipment is installed, not releasing combustion products into the external environment. This is essential for oversized rooms, in which there is a rather weak ventilation system. For this reason, for such equipment there is no need to equip the traditional chimney, only the lateral coaxial will be sufficient, which is also called coaxial. It is installed by first connecting two pipes that are located in each other. To ensure the supply of fresh air into the combustion chamber, as well as the outflow of combustion products, this element is necessary. Due to the fact that there are holes in the case, the installation of additional batteries in the rooms is not required. A single boiler will be sufficient to provide full heating. Parapet boilers are connected by the same principle, which is used in the case of convectors. This involves the use of spigots, which are necessary for connection to the water supply system and the gas pipeline. This is true if the equipment is dual-circuit, it is fixed to the wall surface using brackets.

Council of the master

The coaxial type chimney has a small diameter and can be laid directly in the outer wall, on which the equipment itself is mounted. The branch pipe is recommended to be displayed near the window, thus it will be easier to monitor its state during the functioning of the heating system.

Main advantages

If you decide to choose the heating boiler for the thermo-technical boiler, you should first familiarize yourself with its main positive features. Among them, one can single out the fact that the equipment has a closed combustion chamber. For this reason, there is no need to install a full flue. The boiler can be installed in any room in which one of the walls must necessarily be external. Full heating of the entire room is ensured by the presence of convection apertures in the body of the unit. The use of additional radiators is not required for the reason that the boiler is both a battery and an oven. The equipment can be installed in a city apartment, only electricity and gas will be needed for this. If we are talking about an apartment, then the equipment is installed in the window space, in the kitchen. As an alternative, you can use the boiler installation near the wall, but it will need to create an external hole, which is necessary for the output of the coaxial chimney. An additional advantage is a fairly wide range of models, which allows consumers to choose the most optimal option for a room of any area. During the purchase it is important to pay attention to the power, which can vary from 15 to 40 kW.

Considering the parapet boiler "Termotehnik", it should be noted that among its positive features is also versatility. The model range is represented by variants that can have one or two contours. In the case of two circuits, the unit will be able not only to heat the room, but also to ensure the heating of the water, which is true in the absence of hot water. If you decide to equip an individual heating system, the parachute gas boiler "Aton" will be a relatively affordable solution, which makes such equipment profitable. The case has a modern design that does not spoil the overall appearance of the interior, if you decide to install the equipment in the right place.

Disadvantages of the parapet boilers

If you decide to buy a parapet gas boiler "Aton", then you should consider the minuses of this equipment. Among them is a low power, which indicates the possibility of using a small area in the premises. Home masters especially note a minus, which consists in the need for assistance from experts in the issue of installing a coaxial pipe.

Varieties of parapet boilers

If you decide to purchase a floor parapet boiler, you should be aware that the models can differ in reliability, power, and economy. The equipment will have certain technical characteristics. When choosing a certain type of unit, you should be aware that the reliability will depend on the thickness of the steel used in the heat exchanger design. To my great regret, not all manufacturers point to this parameter, when choosing equipment it is necessary to find out this characteristic at the point of sale. This moment plays a key role in the functioning of the parapet boiler. If you decide to choose the parasitic boiler "Thermo", then as an optimal option protrude 3 mm. In the presence of thicker steel, the heat exchange process will be difficult, which will negatively affect the efficiency of room heating. It matters not only the thickness of steel, but also its quality. Determine this parameter can be based on the maximum pressure rating that is allowed by the manufacturer. At a higher pressure level, steel has high reliability and quality. If you paid attention to the boiler parapet "Thermobarrier", it is important to take into account the economy, this figure affects the design of the heat exchanger and efficiency. Experts advise to determine the efficiency by determining the coefficient of efficiency. This parameter will accurately show the efficiency of the device and the heat exchanger. Recently, almost all manufacturing companies have achieved the most acceptable level of efficiency, which can reach 92%. However, it is nevertheless recommended to clarify this parameter at the time of acquisition, since in some cases a few percent may be of great importance. This indicator is the only one that is able to objectively reflect the efficiency of equipment, because different rooms may differ in the level of insulation. To a sufficiently significant technical characteristic should be attributed to the size, as well as the location of the connectors for connection. Choosing a specific type of unit, the size must be selected individually, because the parameter will depend on the conditions and the location of the installation. It is important to pay attention to the location of the connectors, many varieties of boiler equipment suggest both a left and a right variant of connecting the device of the water and gas pipeline. You can also find universal models, which can be connected from either side.

Varieties of equipment by capacity

The parachute pot "Ross" can have different capacities. From the choice of the model with the most suitable capacity will depend on the quality of heating and economy of use of the unit. This is due to the fact that if the power is higher than necessary, then electricity and gas will be wasted. It is often often recommended to use a formula that provides for the selection of equipment with one kilowatt per 10 square meters. In fact, this calculation can not be called correct, since the indicator is averaged. In practice, it does not correspond to reality. When calculating, which provides 1 kilowatt per 10 square meters, does not take into account the difference between the house and the apartment. It is important to take into account the number of openings, the height of the ceiling, the material of walls and other parameters, from which the level of thermal insulation is added. Experts recommend doubling this formula, using 2 kilowatts per 10 square meters. This will allow you to get a stock that takes into account possible drafts, high ceilings, thin walls and an excessive number of windows.

The boiler "Dani" is parapet, like other models of similar equipment, has economy, low cost and easy operation. It can perform the functions of a water heater and does not involve the arrangement of an additional heating network, since it is a convector and an oven at the same time. Each master will be able to easily connect such an aggregate independently, without resorting to the help of specialists. Two-loop parapet boilers are modern comfortable heating devices that can be installed in any type of premises, for example, apartments or private houses, garages and outbuildings.

In addition to the varieties of parapet boilers

If you have decided to independently connect the parapet boiler, you need to pay attention to additional factors that point to different types of equipment. In a country house or apartment you can use devices that differ in the place of installation, the availability of automation, methods of output of gas combustion products, the type of burner, the type of coolant and the cost. In the place of installation, the units can be floor or wall mounted. The latter are considered more popular, since their power most often does not exceed 30 kilowatts. Undoubtedly, devices that are designed to be mounted on a wall can be more powerful. However, here we are talking about a mini-boiler house, which combines several units according to the cascade principle. Outdoor equipment is considered more powerful and allows heating of buildings, the area of which is equal to several square kilometers.

Types of chimney type boilers

The chimney of the parapet boiler can have forced or natural draft. The first option is a coaxial system, while the second consists of a traditional pipe that passes through the roof. It is often possible to find mention of turbo boilers. They are what we understand as wall-mounted parapet models, but the products of fuel combustion in them are diverted by means of special fans through a coaxial chimney. If the draft is natural, then the equipment burner is open, and air is supplied from the room. If the tube is coaxial, the air is sucked in from outside. Such boilers, as a rule, are used in conjunction with parapet instruments, which improves the environmental conditions in the room, the air is no longer burned, since it comes from outside. Chimneys can be vertical and horizontal, which increases the possibilities for choosing a place for installing a heat generator.

Boiler types by functionality

Parapet boilers can have one or two circuits, in the first case only the house is heated, in the second house it is provided with hot water. They are supplemented by a flow heater, which, as a rule, are copper. This material has the best thermal conductivity. A similar unit can be connected to the system either on the right, or on the left, or on both sides, thereby simplifying the heating layout. This is to the liking of a modern consumer, who increasingly inclines his choice toward parapet boilers.
