The exhausting bureaucratic marathon for signing and agreeing on the permit for the installation of a gas boiler has already been overcome. The thing is left for the installation and connection. Preferably this procedure is entrusted to specialists, but the desire to install a hinged pot and the approaching frosts hasten. How can I connect the heating system with my own hands?

Choosing a gas boiler for your home
The statement that the gas boiler is the center of the heating system is unquestionable. Today, gas boilers are popular among owners of private houses and cottages. Price availability of gas fuel allows to install hinged gas boilers.
However, the richness and diversity of the choice gives rise to the question: "Which hinged gas boiler is better?"
In order not to be mistaken in choosing, it is necessary to understand the types and characteristics of the heating devices, having studied the classification and technical characteristics.
How to distinguish the boiler type
Recall that gas boilers in the features of construction are divided into types:
• boilers floor, placed on the floor or on a platform
• wall-mounted boilers located on a wall in a special niche or frame.
The hinged heating boiler on the back cover has fixing points and hanging brackets for the bracket.
Boiler Functionality
The next distinctive quality of the gas boiler is its functionality, namely: single-circuit or dual-circuit design. The functions of a single-circuit boiler is the heating of the house or apartment.
Two-circuit boilers are fully capable of providing the consumer with heating and hot water supply. There is no need to connect additional equipment.
What is a hinged gas boiler is told and presented here.
Before purchasing a gas boiler, it is not unreasonable to make a small calculation of the capacity of the heater according to the area of the heated space. In addition, it is necessary to have an idea of the type of radiators and the heat loss coefficient. A hinged boiler, the price of which is rather large, should justify the cost side in the next 2-3 years due to savings when switching off from central heating
Ways to connect a wall-mounted boiler
The method of connection of a gas boiler depends on such parameters:
• Ignition (automatic or piezo ignition)
• Type of draft (chimney or turbine).
There is a basic scheme for connecting a gas boiler, which is modified for each type of model.
The main components of the gas boiler
The hinged gas boiler has the following basic components of the system:
• combustion chamber
• Expansion tank
• automatic ignition
• circulating pump
• Bypass heating circuit
• gas pressure stabilizer
• gas temperature and pressure regulators
• Pressure gauge in the heating system
• Built-in board with microprocessor control elements
• heat exchangers for water supply and heating circuits
• control sensors and mode switches.
Installing the wall-mounted boiler does not require an isolated room for the boiler room. Boilers are easy to install in the kitchen or in the bathroom.
Helpful advice
To connect the hinged boiler, use the basic connection diagram. New so far nothing has been invented. Everywhere the same nozzles are 1/2 "and 3/4".
Basic connection diagram
The main elements of the basic connection scheme are: ball valves, coarse filter, collapsible connections ("American").
Ball valves are installed on each pipe, which serve to cut off the gas boiler from the heating system.
A coarse filter installed on a cold water pipe is designed to filter it. Demountable connections are designed for maintenance or repair of the heating system, excluding draining the water.
Before starting work, it is necessary to install the bracket on the wall. The mounting bracket is supplied with the manufacturer. It is recommended to install a gas boiler taking into account the regulatory requirements for location. It is necessary to equip the ventilation system and chimney.
How to connect a wall-mounted boiler
Connection of a wall gas boiler will consist of the following stages:
• installation of the boiler with subsequent fixing to the bracket
• connection of the heating circuit
• connection of the water supply system
• connection to the gas main.
Modern gas boilers have a standard arrangement of inlet and outlet nozzles. Standard sizes allow the connection of the main circuit, the gas supply circuit and the water supply. Visually, in the lower part of the boiler body, these nozzles are visible in an amount of 5 pieces.
The gas connection is located in the center, and on the right and left there are 1/2 "water connections. At the end of the gas boiler there are nozzles intended for connection of the system elements (return and supply) 3/4 ". Connection of the return and supply must be made according to the current norms and rules. Sealants and thread sealers are used to effectively isolate the system.
connection to HVS
The scheme of connection of the boiler hinged to the water supply does not differ from the connection of the heating system. The only additional condition is the installation of a water purification filter. Let's remind, that branch pipes of cold water supply on the boiler are located on the left, hot - on the right.
we connect the boiler to the gas pipeline
When connecting the wall-mounted boiler to the main gas pipeline, it is recommended to use corrugated stainless steel hoses. This material will relieve the headache for a long time: the durability and stability of the material is excellent.
Hose connections to the boiler connections are simple: install the gaskets inside and tighten the union nuts, and then seal the joint.
Make the connection is not difficult, especially after reading the video, which tells about the connection rules.
