How the combined gas and wood boiler works

Efficient heating of your home is necessary for both financial viability and comfort. The hybrid gas and wood boiler is one creative solution that is becoming more and more well-liked. Combining the renewable energy of wood with the dependability of gas heating, this system provides the best of both worlds. But how precisely does it function?

The dual-fuel mechanism at the heart of the combined gas and wood boiler drives its operation. It combines a wood-burning stove and central gas heating, two different heating systems. With this combination, homeowners can take advantage of the cost-effective and environmentally friendly wood fuel alternative while still enjoying the convenience of gas heating.

The boiler starts working when the thermostat registers a need for heat. In the event that gas is chosen as the primary fuel, your home will be warmed by the boiler’s ignition and subsequent heating of the water that is pumped through the central heating system. This procedure guarantees steady and dependable heating, especially in the winter or when instantaneous warmth is needed.

But the adaptability of this system is what makes it unique. The boiler easily switches to wood burning mode when wood fuel is preferred or easily accessible. When the wood burner is in this mode, it ignites and heats the water similarly to a gas burner. Due to this flexibility, homeowners are able to select the fuel source that best suits their needs, taking into account factors like cost, environmental impact, or personal preference.

Additionally, the boiler that combines wood and gas promotes sustainability. One way for homeowners to lessen their dependency on non-renewable fossil fuels like natural gas is by integrating wood as a renewable energy source. Since the carbon dioxide absorbed during the tree’s growth balances the carbon dioxide released during combustion, wood is regarded as carbon-neutral. Those looking for greener heating options will find this feature appealing.

In conclusion, the hybrid gas and wood boiler presents a novel method of heating a home by fusing the sustainability of wood fuel with the ease of use of gas. This system offers homeowners flexibility, dependability, and the chance to lessen their environmental impact by seamlessly integrating two heating methods. Gaining an understanding of this system’s workings is essential to fully utilizing its advantages.

Design and operation of gas-oil boilers

1. Module with the possibility of conversion to gas.

Mixed-type combined boilers for gas and wood have integrated automation that completely automates the combustion process. The module automatically transitions to gas or electricity once the wood in the firebox has burned completely. An electric coil heats the water for DHW.

It is very expensive to install a wood and gas boiler simultaneously in one system. Costs are lowered by 30–40% with the purchase and installation of universal equipment.

Bifuel wood-gas boilers

Gas-wood combination boilers are common in residential settings. The following units are part of the design:

Furnace chamber – made of steel or cast iron. One or two furnaces are installed in the construction. Modification with two furnace chambers, more convenient. A gas burner is installed in the lower furnace. In the upper chamber there are grates for burning wood.

Depending on how well the boiler CT performs, DHW can heat up to 700 liters of water per hour. A built-in 40–120 liter water storage tank is one of the modifications.

Electric-gas-and-wood boilers

Gas, wood, and electricity combined heating boilers use a device similar to dual-fuel units. The installed electric heating element is the primary distinction. Combination boilers that run on gas, wood, and electricity work on the following principle:

The main type of fuel is considered to be wood. After combustion of wood, the gas burner is switched on in automatic mode. The heating process continues without stopping.

A single log laying can extend the autonomous operation time of certain gas, wood, and electricity-powered universal heating boilers by up to 12 hours. This is achieved through the utilization of the gas generation principle.

In this post, we examine the inner workings of a hybrid gas and wood boiler, highlighting its cutting-edge capabilities and advantages for both home insulation and heating. This innovative system gives users flexibility, efficiency, and environmental friendliness by combining the power of wood and gas. The boiler minimizes its environmental impact while delivering dependable heating through the seamless integration of these two energy sources. We investigate how the boiler effectively alternates between wood and gas on demand, guaranteeing both economy and peak performance. We show how this technology gives homeowners a greener and more sustainable way to keep their homes warm and comfortable all year long, from its dual-fuel capability to its user-friendly controls.

Recommendation for choosing a boiler on gas and wood

The choice of gas and wood combination heating boilers is influenced by the heated building’s technical specifications and the requirement for combustion process automation. Keep an eye out for the device’s additional functions, or lack thereof.

The primary standards for selection are:

Performance – one kilowatt of power is enough to heat 10 m² of a building. The boiler is selected in accordance with the need for heat consumption of the building. For a room of 100 m², you will need to install a 10 kW model, for 200 m² – 20 kW, and so on.д.

When the boiler is connected to the main gas supply, a project must be made and all required commissioning permits must be obtained. The same installation guidelines apply as they do to any other gas equipment.

The main manufacturers of wood-gas boilers

A crucial factor that influences the selection of a bi-fuel boiler is the nation of origin and the brand of the heating appliance. High-quality equipment is produced in Russia, Ukraine, and the EU:

Ukrainian and Russian combined boilers – fully adapted to the realities of domestic operation, insensitive to the quality of fuel, voltage fluctuations in the network. Heating boilers on wood and gas, Russian production, produce several leading manufacturers:

Kupper PRO (Teplodar company),

Wirbel (Austrian-German company with the same name),

In terms of reliability and assembly quality, European units marginally outperform their domestic counterparts. There are some glaring flaws in Russian boilers, particularly when it comes to automation and gas generation mode operation.

Russian equipment is always becoming better, and customers’ requests are taken into consideration. We can anticipate producing goods that are capable of competing in the future.

How much does the equipment on gas and wood cost?

The location of the manufacturer’s plant and brand awareness affect price policy. Depending on capacity and equipment, a multifuel boiler made by Russian manufacturer PARTNYOR will cost between 22 and 24 thousand rubles.

The price range for the Finnish equivalent of Jaspi is 120–150 thousand rubles. Significant difference. In actuality, the customer receives an almost entirely autonomous station with a storage tank and automation, giving them complete control over the combustion process, for this amount of money. Every procedure pertaining to the Russian boiler will require manual control.

When a gas boiler is independently remodeled for firewood, the approximate cost of a traditional multi-fuel domestic production unit is frequently incurred.

A viable option for effective home heating is to combine wood and gas in a boiler system. Through the integration of both fuel sources, homeowners can experience the advantages of dependability, economy, and ecological sustainability.

Gas is a convenient and reliable primary source of heat that provides constant warmth. It guarantees continuous heating, particularly in times of high demand or when wood fuel is scarce. Gas contributes to cleaner air and a healthier environment by producing consistent heat output with minimal emissions through its efficient combustion process.

Conversely, wood gives the system more adaptability and environmental friendliness. Wood pellets or logs provide an environmentally sustainable substitute for fossil fuels since they are a renewable and carbon-neutral fuel. Furthermore, burning wood can be more economical, especially for homeowners who have access to free or inexpensive wood sources like wood waste or fallen trees.

In a combined boiler system, the power of wood and gas works together to optimize flexibility and efficiency. Homeowners can depend more on wood fuel to offset costs and lessen their reliance on non-renewable resources during times of high demand or during spikes in gas prices. On the other hand, the gas component easily takes over to maintain steady heating when convenience is of the utmost importance or when there is a limited supply of wood.

Additionally, combined gas and wood boilers now have improved functionality and control thanks to modern technology. Sophisticated automation systems guarantee ideal fuel burning and temperature control, maximizing energy efficiency and reducing waste. Homeowners can effectively manage their heating system by modifying settings in accordance with their schedules and preferences thanks to remote monitoring and programmable settings.

In summary, the hybrid gas and wood boiler presents a convincing option for home heating by combining the sustainability of wood fuel with the dependability of gas. Through the utilization of cutting-edge technology and the combined advantages of both fuel sources, homeowners can experience economical, eco-friendly, and effective heating all year long.
