Features of the combined boilers GAZ-DROV

Additional pipes that are successfully utilized in the construction of warm floors, bath and pool heating, and radiator heating are included with Universal equipment. The firebox with the gas burner beneath it is where firewood, coal, sawdust, and pellets are burned. It switches off automatically when solid fuel is used.

Utilizing the combined gas-drum boilers is made convenient by the steel heat exchanger that runs the length of the case. 92% of the efficiency is achieved when thermal insulation for the walls is achieved using mineral wool. The supply is provided by a copper heat exchanger located in the upper portion of the apparatus. Air dams, which regulate the flow of air, are included in the design.

Advantages and disadvantages

The gas-drum boiler has several benefits over its conventional counterparts.

• two chambers – provide for the use of solid fuel with gaseous;
• the possibility of simultaneously connecting several contours, which allows you to heat several neighboring buildings at once;
• Efficiency is in the range of 90-95%;
• independence from power supply, and if necessary, and gas supply;
• easy installation, repair – no special knowledge and significant costs are required;
• It takes a little area, although it is more advisable to use a separate boiler room for installation;
• A small number of relatively safe emissions.

There were a ton of benefits, but none at all

• The large weight of the structure complicates the transportation and requires the construction of a thorough foundation;
• The higher the productivity of the equipment, the less its functionality;
• To obtain the necessary performance, you need to correctly calculate the power, given that for 10m2 it will take about 1kW.

Note: You should increase this indicator by 30% when working with double-circuit structures.

Device and principle of operation

There are three distinct modifications of gas-wood boilers that differ in terms of both functionality and design:

1. The presence of a module that allows you to convert to gas.
2. Simultaneously two separate fireboxes, for gas and firewood.
3. Heat generator equipped with an electric heating element.

Complete automation is provided by multi-fuel structures. Following firewood combustion, the module autonomously transitions to a different fuel. Electricity is used to heat the water in the hot water.

Existing species

Many varieties of universal heating equipment are available from manufacturers:

Solid fuel with a gas burner

Each installation has a single combustion chamber that is constructed from steel or gray cast iron. The loading door is swapped out for a gas burner in order to convert to gas heating. Equipment performance may be negatively impacted by frequent energy carrier switching. When there’s no chance to heat the house with a particular kind of fuel, wood and gas boilers are in high demand.

Gasual

Allows stone coal to be used in conjunction with a main gas supply. Because the gas boiler runs entirely on gas rather than electricity, you can create autonomous heating.

Gasodiesel

Natural gas or diesel are used for heating.

The design is the reason for the low cost of two fuel units. The apparatus allows the burner to be reinstalled in accordance with a particular fuel type. Certain models have universal burners that can burn both kinds of fuel.

Criterias of choice

You must consider the fuel that is available in a given area when selecting a device. They also accept the room’s measurements, the frequency of equipment maintenance, and the presence of automation. You should compute its thermal power using an appropriate model and consider the quantity of circuits that need to be connected. The subsequent parameters hold significant importance:

• performance;
• hot water supply;
• Built -in Ten;
• design features.

Note: In order to connect equipment to the gas line, the necessary permits must be obtained and a project plan must be created.

In the realm of home heating and insulation, the integration of gas and solid fuel boilers stands out as a game-changer. This innovative system operates on the principle of versatility, offering homeowners the flexibility to utilize both gas and solid fuel sources for heating. Essentially, it functions by incorporating two separate combustion chambers within a single unit, allowing for seamless switching between gas and solid fuel modes based on preference or availability. This dual functionality ensures uninterrupted heating even in situations where one fuel source might be scarce or impractical. By harnessing the efficiency of gas and the reliability of solid fuel, this hybrid boiler system not only optimizes energy use but also provides a reliable heating solution for households, ultimately enhancing comfort and reducing energy costs.

Instructions for installation and operation
