How to choose a wood stove
Manufacturers produce two types of heating furnaces:
- Long-term burning;
- Periodic burning.
However, in the home most often use stoves of the first type, because they are more economical and can work continuously for several days in a row due to the gradual smoldering of firewood.
Long-burning furnaces function as follows: a heat exchanger with a certain gap between their walls is placed in a special metal case. When the oven is operating, air in this space heats up and heats the room.
The material for making wood-fired furnaces is:
- Heat-resistant stainless steel with a thickness of about 5 mm. The life of such units is up to 10 years.
- Cast iron, which holds heat much longer and is stronger than steel. The use of this material extends the life of the equipment to 25 years. However, such furnaces have one significant drawback: brittleness. Warm up( harden) such a construction is necessary gradually and then it will last for many years.
- Ceramics, the main advantage of which is a small weight, which allows you to transfer such equipment to any part of the house;
- Bricks are the most durable and reliable material.
Advantages of metal wood stoves
Advantages of metal heating units:
- Ease and speed of installation and dismantling, it's enough just to transfer the stove to the right place;
- Lightweight up to 200 kg, which eliminates the need for a foundation under the device;
- Serves not only for heating, but also for cooking food;
- Ideal for additional heating, as well as for the rapid creation of heat for example in a dacha, which is not a place of permanent residence and with a prolonged absence of owners quickly cools;
Indigirka is a technological novelty
Indigirka is a heating and cooking furnace with a built-in generator for electricity, the function of which is to convert thermal energy into electrical energy. To date, this design is the most advanced heating device developed by the engineers of the company "Termofor".
Such an aggregate at full working load is capable of generating a current of up to 50 watts and a voltage of 10-12 volts after 10 minutes after the fire is ignited.
In case of emergency or other unforeseen situations, such an oven will be a real salvation, because it will provide housing not only with heat, but also with such usual and necessary modern electricity.
Weight of Indigirka is about 54 kg, and the price may vary depending on the region and the availability of additional functions.
Increasing the heat transfer of furnaces on wood
It is much more pleasant to get the most out of it with minimum costs. Applicable to the same statement for heating furnaces on wood.
There are several ways to increase the heat transfer:
- Use hardwood firewood( birch, beech, oak).For example, a birch will give up 25% more heat than an aspen or alder;
- Drown only well-dried wood, the higher the humidity of the fuel - the less thermal energy they give;
- Finishing( surfacing) of the body with metal or cast iron strips, due to which the area of heat exchange increases;
