By selecting the appropriate furnace type and taking into account all pertinent factors, you can minimize your environmental impact while still enjoying a warm and cozy home. Making the switch to a more environmentally friendly heating solution can be easy and satisfying with the correct knowledge and direction.

Subtleties of stove heating in a greenhouse

The majority of gardeners heat their greenhouses in the spring and late fall using furnaces. Most of the time, winter heating is not profitable. The greenhouse’s vestibule, ventilation system, and gas outlets all contribute to the furnace’s increased efficiency and decreased fuel consumption.

Any model’s operating principle is as follows:

1. Cold air from the street enters the room through the pipe of the upper part equipped with a barrier.
2. Fuel is laid in the lower compartment. But oxygen access to it is limited, so combustion occurs slowly. Fuel is rather not burning, but smolder. The intensity of the process is ensured by competent adjustment of the damper.

Thus, long-term, gradual heating is provided with the least amount of fuel.

The following considerations should be made when installing the furnace:

1. The priority task in the greenhouse is soil heating, not air. Therefore, the furnace must be placed closer to the ground.
2. Another option is to raise the beds by 30 – 40 cm or installation of boxes with seedlings on the shelves.

Water for watering plants will also be provided by connecting to the water circuit’s stove.

When it comes to heating your greenhouse, choosing the right furnace is crucial for maintaining a healthy and productive environment for your plants. There are several popular types of greenhouse furnaces available, each with its own advantages and fuel options. Whether you"re considering a wood-burning stove for its rustic charm, a gas heater for efficiency, or an electric furnace for convenience, it"s essential to weigh factors like heating capacity, energy efficiency, and maintenance requirements. Additionally, consider the size of your greenhouse and the climate in your region when making your choice. Opting for a furnace that suits your specific needs and conditions will ensure optimal growth for your plants while keeping your energy costs in check.

Types of furnaces

You can construct a stove by hand if you have the necessary supplies and some basic construction knowledge. Nevertheless, it makes sense to purchase a finished model if you don’t want to put more work on yourself. You must first research the features, benefits, and drawbacks of various models in order to make the best decision.

Vologda

High heat transfer rate model. only needs to lay fuel twice a day. Efficiency of the stove: up to 80%. The way it works is kind of like watching a gas generator burn. Flexible hoses that are fastened to the fuel tank and boiler’s back wall supply the coolant.

The model is not commonly found in private greenhouses, but it is recommended for large-scale installations. The shape "Vologda" is a big barrel that is positioned horizontally.

As long as tubes are fused to it. The furnace comes with a number of options. The smallest moves through the tubes at a speed of five cubic meters per minute of air.

Drawbacks of the model:

• there is no way to adjust the temperature regime;
• bulky and inconvenient in installation;
• requires systematic control during combustion.
• high price.

Utilizing solid wood for wood fuel allows the oven’s combustion time to be maximized.

Betakova stove

The designer’s name was used to give this model its name. It is currently produced in a number of domestic factories.

The range of produced models includes multiple varieties intended for heating spaces of varying capacities:

• Gymnasium student;
• Student;
• Engineer;
• Assistant professor;
• Professor.

It is advised to choose the smallest option, "gymnasium," for small greenhouses.

In terms of structure, Butakov’s stove is a fuel tank with three millimeter-thick steel walls that heats two species evenly along its length:

1. The side are curved and crossed together in the upper part.
2. Front and rear-convection, supplemented by special jet-propelled guns for supplying secondary air to the chamber.

Efficiency is raised in part because of the design, which enhances the furnace’s heat transfer mechanism. Both the regular and gas generation modes can be used with the furnace. Butakov’s stove requires the ash to be completely closed and the gate of 2/3 to be blocked in order to operate in the prolonged combustion mode. The wood will then burn, but the gas it releases will not.

The stove has a 12-hour battery life. To achieve this, the combustion chamber must be as full of fuel as possible before the stove is started, the gate must be adjusted to the desired position, and the chimney’s height must meet the requirements for this firebox volume.

All that is suitable for Professor Butakov’s stove is sawdust or firewood. Since the temperature at which coal burns is unacceptable for the metal used to make the case, coal cannot be used in such a model.

The suggested model should be carefully considered before purchasing a Butakov oven. Some manufacturers do not include secondary combustion chambers, which lowers efficiency and necessitates frequently laying firewood while in use.

Bulereyan (Breneran)

The German or American Bulerians’ oven, which is comparable to the Russian Breneran oven, is a gas generator consisting of two combustion chambers:

• lower – gasification;
• upper – burning.

The furnace’s front side has a gate to control power and a door for loading fuel. The combustion pipe is located on the rear of the firebox. A chimney comes to accompany him.

Pipes for the cold and hot air output are installed on the top and bottom of the firebox. The pyrolysis process is what makes the stove operate profitably. The gas released during combustion helps to heat the air in the greenhouse rather than the fuel returning heat to it.

Ten hours with one load of fuel. Thus, two loads in the morning and evening enable the greenhouse’s temperature to be maintained continuously.

Bourgeois

The most basic greenhouse heating design. It has a simple device. The barrel-shaped firebox has a door, chimneys, a pipe for warm air output, and a fuel-laying jumper in the upper third of the tank.

The following factors contribute to the room’s heating:

1. Moving hot smoke along the pipe laid in the central part of the greenhouse or on its side sides.
2. Heating radiation with stove surfaces.
3. Hot air formed above the jumper and leaving a special pipe.

The bourgeois can work with coal, firewood, and leftover lumber. The type of fuel and the air’s ability to enter the furnace determine how intensely it burns.

Selecting this kind of heating is worthwhile only in situations where burning can be continuously controlled. One of the stoves’ main drawbacks is that it requires systematic fuel laying.

Bubafony – an advanced bourgeoisie

The creator of the model was given the name Bubyakina Afanasy. The design alludes to furnaces with extended burning times. The fuel tank is split into sections using a clamping circle and a piston as part of the design. It is supported by the fuel inside. Fuel burns at the bottom as a result, and pyrolysis gases burn at the top. The pipe serves as both the oxygen supply and the piston handle at the same time.

You can use any fuel in the furnace, including garden and household waste. The model’s benefits include its effectiveness, ease of use, and potential for unattended operation. Nevertheless, Bubafoni’s limited range is a serious disadvantage. The fan needs to be added to the design in order to solve the issue.

Slobozhanka

From the outside, this stove looks like a potbelly stove with the addition of a caloriece and a gas generator. The utilization of combustible gases boosts the furnace’s efficiency. They serve as an extra heat source even though they are not visible.

The combustion chamber is filled with fuel that is fed in from above. The entire process of heat release takes place in a downward direction.

Three distinct methods of air supply can be distinguished based on the unique design of the "Slobozhanks":

1. The pipe hole from top to bottom with a Mr.
2. Pipe located in the center of the device. The air in this design enters below.
3. Side pipe located in the lowest of the furnace.

The "Slobozhaanka" housing is shaped like a barrel and contains seven vertical pipes. The model consists of:

• lack of a pallet for removing not burned residues;
• the need for regular fuel laying.

How to choose fuel

Long-burning stoves can burn practically any kind of fuel, including coal, firewood, sawdust, and biomass.

The decision is based on the greenhouse’s specifications:

• Sawdust – an affordable type of fuel for summer residents, next to the site of which is a sawmill. Most often they can be taken for free, since the workers simply collect and throw these waste.
• Firewood – Optimal choice for a greenhouse furnace. In a small greenhouse, fuel can be laid once a day. Firewood is available and environmentally friendly.

• Coal. The main advantage of this type of fuel is high calorie content. Disadvantages – the release of toxic substances, as well as a large amount of waste. Some types of coal with improper storage can be dangerous because they are prone to spontaneous combustion.
• Briquettes. This type of fuel combines the advantages of firewood and coal. Briquettes are rapidly flared up, maintaining prolonged burning. Fuel has high efficiency, efficiency and lack of harmful emissions.

Greenhouse Furnace Type	Criteria for Choice
Wood-burning Stove	Good for off-grid; consider fuel availability and storage
Electric Heater	Easy to install; look for energy efficiency ratings
Propane Heater	Portable; check safety features and cost of propane
Solar Heater	Environmentally friendly; assess sunlight availability

Making the right greenhouse furnace selection is essential to keeping your plants in a productive and comfortable environment. With so many options available, it’s critical to comprehend the most common varieties in order to make an informed choice.

The wood-burning furnace is a popular type that is renowned for its dependability and affordability. It is a green option because it runs on wood, a resource that is replenishable. To guarantee best performance and safety, it needs routine maintenance, though.

The natural gas or propane furnace is another well-liked choice. These kinds provide steady heat output and are practical and simple to use. Because of their effectiveness and capacity to maintain consistent temperatures, they are frequently chosen for larger greenhouses.

There are electric furnaces as well, and they are renowned for being simple to install and clean. They may require more upkeep than other types, but their simplicity and low maintenance costs make them popular choices.

Think about things like your greenhouse’s size, your spending limit, and the fuel supply in your area when selecting a greenhouse furnace. Prioritizing energy conservation and safety features will also help to keep your greenhouse a safe and healthy space for your plants.

Keep in mind that purchasing a high-quality furnace is an investment in your greenhouse’s future. You can create the ideal growing conditions for healthy plant growth all year long by selecting the right type and taking into account all the relevant factors.
