How to make a heating greenhouse on wood?
There are a large number of heating systems for greenhouse premises. The article provides a detailed description of the simplest and most affordable way to heat a greenhouse - a wood-burning stove.
Why are stoves installed in greenhouses?
Using a wood-burning stove, optimal temperature conditions are maintained inside the greenhouse for growing plants. In addition, heating with wood is the most economical option available. Fire chambers can be made of brick or metal.
The first material heats up longer, but it also keeps heat for a long time and does not dry the air. The second, in turn, releases heat only as long as the combustion process occurs.
Types of greenhouse stoves on wood
Heating equipment on wood can be of several types. Wood is used as a fuel, it burns, generating heat.
Each such installation consists of the following parts:
- fuel combustion chamber;
- channels for air distribution;
- convection shirt.
A detailed description of each species is given below.
Brick oven with a hog
The construction is a massive brick stove with a horizontal pipe.
Important! To completely warm the soil, the heating device must be deepened into the ground or raised beds 30-40 cm up.
To make it, you need:
- metal pipes;
- two steel plates;
They begin construction with the foundation laying, it is formed from monolith and cement. Then the furnace itself is built, two pipes are installed in its upper part, through which air will circulate. A water tank is installed above the firebox, which will prevent air drying out.

Standard greenhouse stove on slivers and firewood
A similar design consists of:
- fuel tank with two compartments;
- openings for laying firewood;
Did you know? With the help of the furnace, you can predict the weather: a strong draft signals the onset of frost, and a weak draft indicates upcoming rains.
It is a metal cylinder placed horizontally and divided from the inside in two using a metal partition. Below is a fuel chamber with a door for loading firewood.
Chips are poured into its upper part, which also emits heat during smoldering. For the manufacture of such a furnace, two barrels welded together are suitable. When operating the device, it is necessary to leave a third of the fuel tank free.
Heat Exchanger Furnace
A heat exchanger is a device that is able to receive and give off heat without generating it on its own. For example, it is the water that circulates in the system, or the air circuit. To build such a heating element, it is necessary to connect thick-walled metal pipes to the heating installation and run them around the perimeter of the greenhouse.
How to make your own heating a greenhouse for wood?
The technology for constructing a heating system for a greenhouse is simple. Below is a detailed description of the manufacture of a long burning furnace from a barrel.
Tools and materials
To work, you need such tools:
- welding machine;
As materials use:
- metal barrel;
- a chimney pipe;
- steel strip.
Assemble the firebox as follows:
- Cut off the top cover from the barrel.
- A side hole is cut through for mounting the chimney.
- In the lower part of the case it is necessary to make an ash pan - a square hole through which the combustion products will be cleaned. A door is also constructed so that it fits snugly against the barrel.
- The previously cut off cover is evenly reduced so that it passes inward.
- They form a blow. A hole is cut out in the center of the lid, to which a small-diameter tube is welded.
- Steel strips are attached to the bottom of the lid, which serve as a kind of cargo for pushing firewood.
- Separately, a lid is made that will close the device; a hole for a pipe is made in it.

It is simple to heat the greenhouse in the winter, it is enough to make a wood-burning firebox using improvised materials. The above is a detailed instruction for the manufacture of such a device at home.
