Gas boiler equipment today is becoming more and more popular when installing heating systems in private houses in the city and suburban buildings, where central communications are not connected. Other market offers include single-circuit and double-circuit models, floor and wall-mounted equipment options, with and without chimneys.
Devices can be volatile or autonomous. All these parameters are important to consider when buying heating equipment. For example, wall-mounted boilers have less power than floor-mounted ones. They are able to heat a not so impressive area. However, their installation is simple, and the structures are compact in size and attractive in design.
As for floor models, they are usually installed in large rooms. Their weight is significant, so it is forbidden to hang such equipment on the wall. The unit requires its own foundation, which should not be connected to the base of the house itself. If you are still notIf you know which model of gas heating equipment to purchase, then you should consider at least one of them. A great example would be Navien Deluxe, which will be discussed below.
Overview of the boiler 24K
You can purchase the installation mentioned above for 25,000 rubles. It is a convection equipment that has two circuits. This suggests that with the help of the unit it will be possible not only to provide heating, but also the supply of hot water in the house. The device has a stable anti-freeze system, it can be used when the fuel inlet pressure in the gas pipeline system is low.
Included in the kit is a remote control, which simplifies operation. The heat exchanger is made of stainless steel. The design provides for a modulated turbocharging system. Navien Deluxe ensures stable and safe operation even with frequent power fluctuations.
If the temperature in the room drops to a certain level, the boiler will automatically work, which protects it from freezing. When the heating water temperature drops to 10 °C, the circulation pump starts, this happens automatically. With it, the device ensures the circulation of the coolant in the system. If the heating water temperature drops to 6 °C, the burner will turn on, which will help heat the coolant to 21 °C.
Specifications
"Navien Deluxe" has a power of 24 kW,which is mentioned in the title. The heating area reaches 240 m2. The efficiency is 90.5%. This boiler is wall-mounted and has a closed combustion chamber. The convection unit is electronically controlled.
Heating boilers can be classified into models that are connected to a single-phase network, as well as devices that operate from a three-phase power supply. On sale you can find models connected to a single-phase or three-phase network. As for the described equipment option, it operates from a single-phase network.
There is a built-in expansion tank and a circulation pump in the design. Navien Deluxe uses natural or liquefied gas as fuel. The consumption of the latter is 2.15 kg/h. If the equipment uses natural gas in operation, its consumption will be 2.58 m3/h.
Before purchasing the described device, it is important to ask about the pressure of natural gas, the nominal value varies from 10 to 25 mbar. The temperature of the coolant can reach 80 °C, while its minimum value is 40 °C.
The allowable pressure of liquefied gas is 28 mbar. The Navien Deluxe gas boiler provides a hot water capacity that is equivalent to 13.8 liters per minute. The maximum water pressure in the circuit is 8 bar. As for the water pressure in the heating circuit, it reaches 3 bar.
Consumer Reviews
Before you purchase the described device, you must familiarize yourself withconsumer opinions. From them you can find out that the manufacturer has equipped the boiler with functions such as a pressure gauge, thermometer, auto-ignition, room thermostat and a flame modulation option. Reviews of the Navien Deluxe also indicate that the display and remote control act as additional features.
Protection functions are:
- overheat protection;
- gas control;
- autodiagnosis;
- frost prevention mode;
- air vent;
- safety valve.
Additional opinions
The dimensions of the device, according to consumers, are quite compact and are 440x695x265 mm. To connect, you will need the diameter of the gas pipe, it is 1/2 , the same parameter is also characteristic of the pipe for connecting the hot water circuit.
But when connecting the heating circuit, you can use a pipe with a diameter of 3/4 . Consumers like the Navien Deluxe 24 gas boiler also because it has a low weight, the mass of the device is 28 kg.
Working with voltage fluctuations
The manufacturer made sure that the boiler could work stably, ensuring safe operation with frequent voltage fluctuations in the electrical network. If they reach 30 °C, then the protective chip on the microprocessor is activated. The device will work without interruption.and failures, thereby extending its service life. Breakdowns can be prevented.
Reduced pressure operation
"Navien Deluxe", the price of which was mentioned above and is acceptable to most consumers, will be able to work with low fuel inlet pressure in the gas pipeline system. You will be able to use hot water with its low inlet pressure. The boiler will operate at rates up to 0.1 bar. Due to this, the unit can be operated in residential areas, where there is a weak pressure of water in the water supply system. Sometimes it happens that the operation of the water supply system is characterized by pressure drops. Under such conditions, the equipment will also remain operational.
In conclusion
The gas boiler Navien Delux Coaxial 24k has many advantages over analogues. For example, the kit comes with a remote control panel. Its scoreboard is Russified, which allows you to control the operation of the device, save gas and reduce heating costs, while maintaining a comfortable temperature, taking into account the specific characteristics of the room. With this function, you can set the most suitable domestic water heating mode.
The remote control has a liquid crystal display with built-in backlight, which will allow you to change the operation parameters of the boiler even in a dark room. This is relevant, because the described equipment is usually installed in utility rooms, where there is not always good lighting.
