Today, autonomous gas supply systems are quite common, as the main source of heat in which is liquefied gas. A gas boiler for liquefied gas is a fairly popular technique. According to statistics, every year such equipment gains more and more fans who refuse in favor of a safer, more efficient and affordable fuel from the main gas pipeline.
Affordable cost and convenience are precisely those qualities that are decisive when choosing a heating system for liquefied gas. But this list cannot be called complete. Among the positive features, consumers also note the lack of the need for servicing the described equipment. This distinguishes it from other varieties of gas boilers, some of which can make noise or form a huge amount of soot. That is why such devices require a separate room for installation, but only a professional can do such work.
How to choose a liquefied gas boiler by type and efficiency
In the domestic market today heating boilers operating on liquefied fuel are presented. They are made by a variety of manufacturers. Each model has unique performance and cost. In order for heating to be more economical and efficient, it is necessary to determine the type of unit, taking into account the peculiarities of its operation.
A gas boiler using liquefied fuel can be classified as one of the varieties. Among the most common, single-circuit boilers should be distinguished, which are intended only to meet the needs of heating. The second type is double-circuit boilers, which allow you to equip the heating system and provide hot water supply. Different models are designed for installation on the floor or wall. The boiler can also be classified by the combustion chamber, which can be open or closed. It is also important to consider the efficiency. The higher it is, the more economical and rational the equipment will consume fuel.
Boiler selection by capacity
A gas boiler for liquefied gas must be selected taking into account the power of the device. When calculating, the area of the room is taken into account. Thus, for every 10 m 2 of heated area, 1 kW of thermal energy will be needed. At the same time, the height of the ceilings should not be higher than 3 m.
This method of calculating power can not be called accurate, but it helps consumers when choosing a unit. If you decide to purchase a gas boiler for liquefied gas, then you must take into account additional factors such as the quality of insulation, the size of doors and windows, as well as the availability of heat consumers.
Boiler selection by additional parameters
Gas boilers operating on liquefied gas should be selected taking into account the possibility of operation of the equipment at low gas pressure. Such equipment has a high level of efficiency. It should be within 90% and above. If you do not have the opportunity to install a large gas tank, then you can use 50-liter cylinders. However, even in this case, at least two should be established. For this approach, it is necessary to use special adapters that ensure continuous operation of the equipment during the transition from one cylinder to the second.
The consumer makes the right choice if he prefers liquefied gas as the main power source for the heater. If you purchase a solid fuel boiler, then during operation it will require human intervention, this should include fuel enclosure and cleaning. As for electrical devices, their operation is possible only if there is power from the mains. Oil-fired boilers with diesel fuel are also not very convenient, because they cannot work silently, they produce soot, which quite often makes consumers think about replacing them.
Choosing a boiler by model: Rinnai RB-257 RMF
If you need a wall-mounted gas boiler for liquefied gas, then you can pay attention to the model that was mentioned above. It is a 29 kW equipment. This dual-circuit device costs 48,900 rubles. The maximum heated area is 290 m 2 . The design has a turbo-cyclone burner that can run on liquefied or natural gas.
The operating pressure is 3 mbar. The maximum gas flow rate is equivalent to 2.85 m 3 / h. The manufacturer claims that the equipment can operate with complete combustion and minimal emissions of NO2 and CO. The coefficient of performance varies from 93 to 95%. The expansion tank in the kit has a capacity of 8.5 liters. An additional option is frost protection. This gas boiler for liquefied gas, the fuel consumption of which was mentioned above, has a fairly compact size, which is 60x44x24 cm. As for the weight, it is 29 kg.
Should I choose a model Rinnai RB-167 RMF
This dual-circuit equipment has a capacity of 18 kW. The device costs 39,900 rubles. The maximum heated area reaches 180 m 2 . The maximum gas flow rate is equivalent to 1.83 m 3 / h. The efficiency remains at the same level as the above equipment. Coaxial chimney when installing the device is discharged through the wall. The equipment weighs 24.5 kg, while its dimensions are 60x44x24 cm.
Single-circuit boiler of the brand Viessmann Vitogas 100-F GS1D870
If you need a gas single-circuit boiler for liquefied gas, then you can consider the model Viessmann Vitogas 100-F GS1D870, which is intended for heating rooms with an area of 200 m 2 . This unit will not create problems during installation, as it has a fairly compact size, so you can install it even in a small room.
The heat transfer surfaces of this equipment variant are reliable, because they are made of gray cast iron coated with scaly graphite. The burner is made of stainless steel, and the manufacturer managed to achieve efficient energy consumption thanks to weather-dependent automation.
This gas boiler for liquefied gas for heating provides a silent start and high reliability of ignition. Among the main advantages should be highlighted:
- reliability;
- economical and efficient work;
- attractive design;
- compactness.
Consumers, however, also highlight cons, the main one is the high cost.
Double-circuit boiler Rinnai RB-307 RMF
This equipment has a rather high cost, which is 52,900 rubles. The device is hung on the wall. Its power is 35 kW. The maximum heating area reaches 350 m 2 . The design has two circuits, one of them provides hot water supply, while the other - heating.
Antifreeze or water can act as a coolant. Hot water is supplied in a volume of 15 liters per minute, this is true if its temperature reaches 40 ° C. The maximum gas flow rate is equivalent to 3.52 m 3 / h.
Conclusion
When choosing a gas boiler for liquefied fuel, it is necessary to choose equipment with a higher power than its recommended level. This is due to the fact that the house is not always well insulated, and the height of the ceilings complies with the standards. In addition, if you choose equipment with power without a margin, then the device will work for wear during severe frosts, which will quickly damage the unit.
