Among the presented models there are boilers that differ in installation method - mounted and floor units. Boilers are also divided into two segments: single-circuit - intended only for heating and double-circuit - in addition to heating, they are responsible for organizing hot water supply.
The cost of a boiler is not the most important quality criterion, so we will pay attention to the technical features of each model, highlighting the most important ones from among their many. To make it easier to understand, let’s first understand what a boiler with an atmospheric burner is and what its features are.
Operating principle of an atmospheric boiler
Typically, atmospheric gas boilers are used for heating a private house or for individual heating of an apartment. The average power of the units is in the range of 15-40 kW. This figure is considered sufficient to heat a room up to 400 sq.m.
The atmospheric burner is the main heating device; it consists of the following parts:
- Nozzle;
- Burner head;
- Ejection tube with burner holes;
- Burner;
- Flame control sensor.
Atmospheric burners come in the following types:
- Single-stage - operate in “on” and “off” modes.
- Two-stage – capable of operating in reduced or full power mode;
- With flame modulation function - provide optimal gas supply.
To make it easier to understand the principle of operation of an atmospheric boiler, imagine that a heat exchanger is installed above a lit gas stove, and a ventilation duct is located above it.
A boiler into which air enters works in a similar way; combustion products are removed under the influence of natural draft.The presence of a chimney is the main condition for the possibility of installing and operating an “aspirated” one.
The main purpose of an open gas burner is to pre-mix gas with air and then supply the resulting mixture directly to the combustion zone.
The efficiency of operation is due to the intensification of the flame due to the supply of oxygen and reduced fuel consumption.
Single-circuit and double-circuit devices - what is the difference?
A single-circuit heating device differs from a double-circuit heating device only in that it is responsible only for heating the room. At the same time, a double-circuit boiler, in addition to heating, is also designed to solve issues of providing hot water supply.
Owners of single-circuit boilers solve DHW problems by installing additional equipment. Most often this is an indirect water heating boiler connected to the boiler. What is more efficient: a single-circuit boiler or a double-circuit boiler? We'll figure this out now.
The main advantage of a single-circuit boiler in conjunction with a storage heater is that water is heated to a comfortable temperature without cooling the home. While with significant water consumption in double-circuit boiler in automatic mode, the circuit responsible for heating is switched off, and the unit only works to heat water.
The following factors should be considered before selecting a heater configuration:
- Heated housing area;
- Number of water intake points;
- Distance from water intake points to the boiler;
- Number of residents.
In a house with a small heated area, with economical consumption of hot water and close placement of water intake points, the optimal solution would be to install a double-circuit boiler.
If hot water is simultaneously consumed from several water intake points, the water temperature may be lower than required. In addition, with a large housing area, additional inconveniences arise. In double-circuit boilers, the priority is DHW; when hot water is consumed, the circuit responsible for heating is turned off.
But these issues are also resolved at the level of the unit design. There are double-circuit boilers that heat water in flow mode and are equipped with a built-in boiler.
The latter provide a supply of hot water of 30-60 liters, but at the same time gas consumption increases slightly. In addition, the weight of the boiler and its overall dimensions increase significantly.
We can conclude that if the needs are met, the optimal solution will be installation of a double-circuit boiler flow type. If you want to have a sufficient supply of hot water at a comfortable temperature at any time without cooling your home, then it would be preferable to install a combination of a single-circuit boiler with an indirect heater.
In addition, if there is a need to increase the need for hot water, boiler You can always replace it with a larger capacity boiler. As a result, the price of such a combination will be higher than the cost of a double-circuit boiler, but the issue of hot water supply and heating will be reliably resolved.
Differences between floor-standing and wall-mounted boilers
As a rule, a wall-mounted single- or double-circuit atmospheric gas boiler is a kind of mini-boiler room with a built-in expansion tank, a circulation pump, and an electronic control board. Options are available for equipping with a valve for connecting an indirect heating heater and weather-compensating programmers.
Main advantage wall-mounted boiler – this is its compactness, low weight, high functionality, ease of installation. This unit is ideal for installation in cramped conditions; operation in a residential area is allowed. Modern mounted boilers have sufficient power to heat a house with an area of up to 200 sq.m.
Floor-standing boilers have large overall dimensions, and their weight can be 3 times the weight of a wall-mounted boiler with similar parameters. This is due to the fact that floor-mounted units, unlike wall-mounted ones, are equipped with cast iron heat exchangers.
The service life of such boilers is 20-25 years. At the same time, wall-mounted boilers with steel or copper heat exchangers will last you 8-10 years.
Basic criteria for choosing a boiler
When choosing a boiler with an atmospheric gas burner, you need to pay attention to the following main characteristics:
- Power;
- Number of circuits;
- Installation method: floor-mounted or wall-mounted;
- The material from which the heat exchanger is made;
- Automation and security
Let us dwell on each of the criteria in more detail, and consider all the main points associated with the given technical characteristics, with the exception of those that have already been discussed above.
Heating unit power
The quality of heating and the creation of a comfortable temperature in the room largely depend on the power of the boiler.
At boiler power calculation need to take into account:
- Room area;
- Room volume;
- Thermal conductivity coefficient of walls, windows and doors.
In order not to dive deeply into numbers and calculations, you can take another, simpler route. It is generally accepted that to heat 10 square meters of housing, 1 kW of boiler power is sufficient for standard ceilings with a height of 2.5 m and insulation of the room. Thus, it is enough to divide the area of the room by 10, and we obtain the theoretically required boiler power.
The resulting figure must be increased by 20% to ensure normal operation of the boiler during peak load periods. To obtain a sufficient volume of hot water, which is especially important for flow-through double-circuit boilers, the power must be increased by 25%.
Material for the manufacture of heat exchanger
The main materials from which the heat exchanger of an atmospheric boiler is made are cast iron, steel, stainless steel and copper. A cast iron heat exchanger has almost no power limitations. It is reliable and durable, thanks to its excellent anti-corrosion properties.
But this also has its own characteristics - cast iron can crack due to the temperature difference at the point of water entry and the heating zone. Design solutions include the prevention of low temperature corrosion by installing a four-way valve.
Cast iron heat exchangers are installed in floor-standing boilers. The products are large in size and weight.
Steel heat exchangers are used by domestic boiler manufacturers due to their low cost.Such heat exchangers do not require installation, they withstand thermal loads well, but at the same time they are significantly inferior to cast iron heat exchangers due to their low corrosion resistance.
A good alternative to steel is a stainless steel heat exchanger. It combines all the positive qualities of steel and cast iron - it is durable, immune to thermal shock, and has high corrosion resistance. But at the same time, boilers with stainless steel heat exchangers are more expensive.
Copper is flexible and conducts heat well. Heat exchangers made from it have many fins and are characterized by a small volume, due to which it is possible to reduce the size and weight of the boiler.
Copper heat exchangers are used in wall-mounted boilers, providing quick heating, which reduces fuel consumption. Due to its compact size and small amount of water, a circulation pump is required to avoid boiling.
Automation and security
Automation ensures safe operation of the boiler, economical fuel consumption, and helps increase the level of comfort when operating the equipment. Price automation for gas boiler determined by the number and complexity of programs and functions.
Some of them are considered basic and should be present in any gas boiler. They are responsible for preventing gas leaks as a result of various non-standard situations - flame extinction, drop in gas pressure.
There are two types of automation – volatile and non-volatile. The first is considered the most reliable, but requires a connection to the mains and an uninterruptible power supply. The second is considered mechanical, it is simpler and is autonomous.
Non-volatile automation system
It is characterized by autonomy, high maintainability and low price. The temperature range of the thermostat is selected manually using a thermostat, which has a rod in its design that lengthens or shortens depending on the temperature. As a result, the gas supply valve opens and closes.
The basic automation package includes draft and flame sensors. When the draft decreases or the burner goes out, the gas supply is blocked. Although non-volatile automation is considered simple and reliable, it does not make it possible to operate the boiler in optimal modes, which reduces the service life of the equipment.
Volatile device version
Operating parameters or operating modes are entered on the display or from the remote control, after which the control and regulation systems are launched.
The principle of its operation is based on the operation of solenoid valves, which are controlled by a microprocessor unit.
Main functions of modern automation:
- Temperature maintenance for a certain time;
- Adjustment of thermal conditions depending on the weather;
- Electronic flame modulation;
- Protection of the heat exchanger from overheating;
- System frost protection;
- Protection against jamming of the circulation pump;
- Self-diagnosis.
The disadvantage of the system is its energy dependence; in the absence of electricity, the equipment is blocked. To ensure full operation, the automation must be connected to an uninterruptible power supply.
