Heating systems today can operate on the basis of completely different devices that operate on gas and solid fuels. But, choosing equipment, you need to consider the financial component. For example, a parapet boiler can provide heat to your home and reduce utility bills.
What is a device?
This unit differs from other products in that it perfectly combines the functions of a convector and is equipped with a sealed combustion chamber. The ingress of combustion products into the room is excluded. You can use a parapet boiler even if you do not have the technical ability to equip a vertical chimney.
The possibility of using the device as a convector allows you to not install additional radiators for heating the room in which the device stands. The unit will be able to rationally heat your home. However, the selection of such products is very large. In order not to get confused, it is necessary to consider not only the advantages of the boiler, but also its technical characteristics. In addition, in this article you will learn how to properly mount this type of equipment.
The device and principle of operation of the unit
So, the parapet boiler consists of a combustion chamber, which is sealed and separated from the room. Thanks to this device, combustion products enter the chimney. This device is coaxial. That is, made of 2 pipes inserted into each other. Thanks to this design, the required amount of air is supplied to the combustion zone, and smoke is vented out.
Such a device allows you to abandon the forced-blowing system. There is also no need to equip a direct chimney, which saves space in the room and funds for the construction of this structure. Basically, the parapet boiler has a rectangular shape.
The device is ignited by piezo ignition. When gas is supplied, the flame from the pilot goes to the main burner. Hot gases passing through the heat exchanger heat not only the liquid, but also the unit itself. Thanks to this, it becomes warmer in the room where it is installed.
The heating temperature is monitored by temperature sensors. Upon reaching the set parameters, the gas valve shuts off automatically. Fuel ceases to be fed to the main burner. The ignitor continues to work.
After the coolant temperature drops below a predetermined level, the boiler switches on again. If the ignitor goes out, or the gas pressure in the central line decreases, the unit is blocked. The gas supply is shut off. This indicates the safety of using the boiler.
Product Advantages
You can highlight the following advantages of the unit:
- Reasonable cost.
- High degree of efficiency.
- Quick and easy installation, as well as ease of maintenance and use.
- Small size and compactness, which allows you to use the device even in small rooms.
- Modern design.
- There is no need to clean the chimney and take care of its serviceability.
- Possibility of connecting the boiler to an individual heating system.
- Installation in any room at home.
A parapet gas boiler is a profitable investment and cost savings, especially since you can find it in almost all stores selling heating equipment.
Device disadvantages
This unit has some disadvantages:
- Not very big power.
- Some restrictions on the heated area.
- Low gas pressure contributes to flame attenuation. In addition, the same problem occurs in the event of a sudden gust of wind.
Specifications
The choice of heating equipment begins with the clarification of its characteristics declared by the manufacturer. Parapet gas boiler has such features:
- Power: 7-16 kW.
- Area that the unit can heat: 70-160 sq. m
- Fluid circulation system: natural.
- Additional systems: electronic control board, hot water and power regulator, protective system (from overheating or freezing of the device).
Most popular manufacturers
One of the most popular devices is considered to be the Aton boiler, parapet. This manufacturer has long existed in the heating equipment market. It produces various boilers, which, according to customer reviews, are characterized by high efficiency and efficiency, durability, small size and the presence of additional functions.
Units such as Atem are in demand. This manufacturer also exists on the market for a long time. An important characteristic of the device is a fairly high efficiency - 92% or more. Buyers say that the device is very simple to operate with a convenient interface. Also, the boiler pleases the owners with a beautiful design.
Often in stores you can find the Danko parapet boiler. According to customers, its main advantage is non-volatility. Thanks to the new design of the heat exchanger, it is possible to save usable space.
High performance and manufacturability are demonstrated by devices of the Senior Duval brand. This is a relatively new manufacturer, but its products have already proven their quality, as evidenced by the satisfied owners of such devices.
Types and features of the choice of equipment
Parapet boilers, reviews of which are mostly positive, can be classified as follows:
- Single-circuit. They are intended only for heating the room.
- Bypass. They can not only heat the air, but also provide hot water to the house.
As for the choice of device, then at the time of purchase should take into account such factors:
- Power. It all depends on the size of your home. Approximate heat consumption per 10 square meters. m. area is 1 kW.
- Profitability. Consider the efficiency here: the higher this indicator, the more efficient the device is.
- Reliability in use. All systems should work correctly, without failures.
- Wall thickness of the heat exchanger.
- The size and location of the outputs for connecting the heating system.
- The used heat carrier.
- Electricity Dependence. This parameter should be taken into account if you experience power outages. There are boiler models that can not work without electricity, and this can adversely affect the operation of the heating system in extreme cold.
- The installation location of the device.
- The presence of additional security systems and management.
Installation Rules
A parapet boiler, the price of which ranges from 12-65 thousand rubles, is a source of increased danger, therefore, for its installation, you need to obtain permission from the fire supervision authorities, the gas service and others (if necessary). In addition, the installation of the device is subject to certain rules:
- The installation can be located in any room, but only near the external wall, in which it is possible to make a hole for the chimney. From the inside, it should be treated with special non-combustible materials - steel plates.
- Those objects that can catch fire quickly (furniture, curtains) should be at a distance of 30 cm from the boiler. Otherwise, a fire may result.
- The distance between the device and the facade can vary between 0.3-2.5 m.
- Installation of the boiler is possible only in the room in which good ventilation is equipped.
- The chimney of the device should only be vented outside. You can not equip it on closed balconies or porches.
Mounting technology
After you decide on the location of your device and collect all the necessary tools, you can get to work. Installation of the boiler can be done with your own hands, however, at some stages of installation you will need the help of a specialist. Incorrect connection can be fraught with negative consequences.
So, all the work consists of several stages:
- The first step is punching a hole through an external wall to equip a coaxial chimney. The position and dimensions of the opening depend on the outer diameter of the pipe. It is best to equip a chimney near the window so that you can get to it for maintenance.
- Now you can install the first pipe of the air duct. It must be fixed, otherwise it may shift.
- Next, the section and the chimney pipe are mounted. Fastenings should be fixed so that all parts fit as tightly as possible. In order for condensate accumulated in the pipes to go out, the chimney section must be installed at an angle. Next, adjust the protection.
- Now you can connect the water pipes and install the expansion tank.
- All clearances must be adjusted as accurately as possible: the burner flame must burn evenly.
After the single-circuit parapet gas boiler is connected, it is necessary to call gas specialists. They will not only verify the correct installation, but also conduct an introductory briefing on the use of the device. Without this procedure, the product cannot be started up. An illegal connection can result in a rather large fine.
That's all. Be careful and attentive.
