The question of whether a stove is needed for a garage rises immediately after warm days are replaced by a cold season. And although antifreeze is poured into the car's cooling system, the cold adversely affects the battery, which in the winter simply does not want to start the car. At the same time, the motor warms up for a long time, the oil thickens, and the owner of the garage has an unpleasant feeling in it. Therefore, in this article we will deal with ovens that can be used in garages, tell about their varieties, pros and cons, and also give examples of designs.
To disassemble in garage furnaces, it is necessary to understand that ordinary stoves that heat houses are here will not work. A unit is needed that would evenly fill the space with heat, penetrating even into the viewing pit. Today, manufacturers offer a fairly wide range of garage furnaces, but do they all cope with their responsibilities. After all, the garage has a completely different ratio of square-cube. Briefly about it.
What is the principle of cooling the garage
What is the ratio: square-cube. About this parameter heat engineers know firsthand. The thing is that the smaller the structure, the greater the ratio of the area of its limiting structures to the internal volume of the room. So, for its heating will require more thermal energy.
So that you understand what we are talking about, let's compare two objects: a house 10x12 m in height 5 m, a garage 7x4 m in height 2.25 m. The volume of the house is 10x12x5 = 600 m³. The area of structural elements, and these are four walls, floor and ceiling, through which heat loss occurs is 460 m² (it is easy to calculate, everything is at the level of the school curriculum). Now the volume of the garage, which is equal to 63 m³ and the area of its restrictive structures - 105.5 m².
Now it is necessary to compare the ratios of the total area to the volume of each object. It turns out at home: 460/600 = 0.77, at the garage: 105.5 / 63 = 1.67. That is, a comparison shows that the garage has almost twice as much heat loss as the house. It turns out that the stove, which will have to be used in the garage, should be more powerful.
Of course, you can take into account that the garage temperature may be lower than in the house. For example, the optimum it will be no more than + 16C. But even in this case, the heating element will still be more powerful than that used in the house.
Rules for heating a garage
So, having dealt with heat losses, we turn to the question of how to heat a garage. Firstly, it should be noted that a more powerful furnace is a big fuel consumption. So, it is necessary to purchase a heating unit of economical action, which has a high efficiency.
Secondly, the stove must heat the garage room quickly. And if it concerns a private garage, then it should cool down quickly. This is due to fire safety requirements. Usually this category includes wood burning stoves. They quickly heat themselves and heat the room (15-20 minutes), and also cool down quickly. But due to low fire safety, such units are rarely used.
