A properly installed heating system will ensure high-quality heating of the room and will save fuel consumption. Gas units are the most common, since the gasification network is extensive. In most houses, you can see the AOGV boiler: Heating Gas Water Heating Unit.
Design AOGV
The device has a simple design and is single-circuit. It has a small capacity, but its efficiency is 89%. There is no special difference between such a model and other heating devices, but all devices are classified according to GOST. The number after the abbreviation indicates the power of the equipment.
AGV - boilers for a private house, which are made in the form of a welded structure, which forms a water jacket for the combustion chamber located inside. A gas burner with all controls is located at the bottom of the device. At the top there is a gas outlet pipe through which combustion products are removed from the furnace.
On the rear panel of the boiler there are threaded pipes to which the heating system is connected. To control and maintain the set temperature, a temperature controller is used, equipped with a handle with divisions. It is this element that simulates the flame power of the main burner.
How to turn it on
To turn on gas boilers AOGV, you need to carry out such actions:
- Turn the control knob and set it to the ignition position.
- Press the handle down all the way and hold it in this state for at least 30 seconds.
- Press the piezo igniter button. Do not immediately release the handle as soon as the flame appears. This should be done smoothly at least one minute after ignition.
- If the flame is extinguished, the procedure must be repeated after 60 seconds. If, when you release the handle, it lights up, the handle rotates counterclockwise to any position from 1 to 7.
To turn off the burner, turn the knob back to the ignition position.
When installing gas boilers AGV, heating can function autonomously. Thanks to automation, control and management of the apparatus is carried out without human intervention. In addition, the equipment is universal, as it can work not only on natural gas, but also on liquefied gas, for which you just need to replace the burner. In the absence of electricity, instead of an electronic control system, you can use a mechanical one. Not every model has such features.
Advantages and disadvantages
The device has the following advantages:
- ease of control - the parameters are adjusted in automatic or mechanical mode;
- the ability to adjust the temperature of the liquid in the system within certain parameters;
- high-quality production of equipment, as well as its components by a domestic company - in the event of a breakdown, there will be no problems finding spare parts;
- non-volatility and versatility;
- the possibility of using any pipes for mounting the heating system;
- durability;
- the ability to choose models: floor, wall, single or double circuit (modifications AOGV);
- stability of the apparatus even with strong fluctuations in gas pressure in the system;
- good level of thermal protection: when any malfunction occurs, the device will automatically turn off.
AGV boilers have a relatively low cost, therefore, are popular. However, they have disadvantages:
- outdated design;
- Efficiency at the level of 85-56%;
- until the unit reaches 30 degrees, there is a risk of condensation in the lower part of the structure, which can extinguish the burner.
When installing AOGV heating, you need to understand that these devices are designed for domestic heating systems.
Heater Parameters
When choosing a heating equipment, you need to pay attention to its technical characteristics:
- rated power: 11.6-29.0 kW;
- fuel consumption: main - 1.9-3.56 cubic meters / hour, cylinder - 0.86-1.21 kg / hour;
- heating area: 120-400 sq.m .;
- Efficiency: 85-90%.
The case can be rectangular (for high power models) or cylindrical.
AOGV insert in heating
Since it is not difficult to include AGV in home heating, you can do it yourself, but first you need permission from utilities. The inset suggests connecting the unit to the heating pipes, as well as to the gas main. To prevent particles of scale and dirt from entering the boiler, coarse filters must be installed on the inlet pipes. All threaded connections are sealed with tow, o-rings.
Shutoff taps are mounted on the water pipes. Only the person who has access to this kind of work can connect the boiler to the main gas main. The gas pipe is also connected with additional sealing. When connecting, copper products or corrugated hoses are used.
Rubber parts are not used, since over time they crack and can let in gas, which, accumulating in the room, will lead to disastrous consequences. A flare nut is used to secure the corrugated hose.
Mounting Features
In order for the OGV units to work properly after installation, the following recommendations of specialists are followed:
- if it turns out, it is better to install the heating element in a separate room;
- for outdoor options will have to build an additional fortified foundation;
- the diameter of the chimney should not be less than 14-15 cm, and its height - 5 m;
- the smoke exhaust pipe must be additionally insulated so that condensation does not appear inside;
- if there is an open combustion chamber in the design, the room is equipped with forced ventilation;
- in front of the boiler, a sheet of metal 1 * 1 m in size is beaten on the floor;
- the minimum distance from the walls during installation is 20 cm, and all surfaces must be treated with non-combustible material.
AOGV is a floor or wall heating unit that works equally well both in a private house and in an apartment. However, the selection of equipment must be done correctly. It is better not to select high-power devices for small structures, as this will lead to unjustified fuel consumption.
