Features of garage heating
Garage space settles for specific needs. These needs must be met by the heating of the garage. But in any case, it is important to determine the way that will be the most economical and safe. The right approach will provide the room with an ideal heating system.
It is necessary to choose a heating system that will block work in case of failures and malfunctions. Therefore, when creating a cheap heating is worth considering, and not whether it will lead to serious problems. The most convenient is to choose an economical option that can provide the desired temperature regime with minimal energy expenditure.
Garage heating should meet the following functions:
- resistance to temperature extremes;
- autonomy, which will allow to continue heating in the absence of energy.
Creating an economical garage heating system will be possible with a competent approach to the insulation of walls, roofs, garage doors, as well as with a well-designed ventilation system. Sometimes competent arrangement of garage insulation is enough to maintain the car and start its engine without problems. If the garage still requires heating, you need to initially decide on a project option.
Before its creation it is worth considering what types of fuel are possible for use in a particular system.
As a fuel for the garage heating system can be considered:
- solid species (firewood, sawdust, coal);
- liquid types (fuel oil, diesel, water);
All types of fuel have some features that imply the use of this or that equipment. Depending on the type chosen, it will be possible to create this or that heating system.
For example, you can install garage heating cheaply and quickly if you choose equipment that runs on wood or other solid fuels.Equipment of this type is not recommended to be installed near combustible materials that are in large quantities in the garage. Therefore, wood or coal stoves for the garage can not be called fireproof heating option.
Gas boilers can be installed in the garage if a gas pipeline is connected to the building. In the absence of a central gas pipeline, it is possible to consider equipment operating on liquefied gas. The boilers are different in configuration, and are also equipped with an automatic security system. The only significant feature is the impossibility of storing a gas cylinder inside the garage.
Another option that has its own characteristics - heating with electricity.
The main advantages of the equipment:
- small dimensions;
- no need for chimney.
Lots of options for each type of equipment makes you think about the choice. Consider them in more detail.
Economical way to heat the garage - heating with solid fuel Heating in the winter will provide a homemade stove working on wood. The manufacture of such a furnace is available at home. Buying ready-made equipment is not expensive.You will need to think about the installation of the chimney. It is also important to consider a way to store a stock of firewood, coal, or other solid fuels. It takes time to procure solid fuels, and the chimney will have to be periodically cleaned from soot.
The potbelly stove can work not only on solid fuels, but also on diesel fuel. Diesel fuel is expensive today, so waste fuel is often used for such stoves, and it is not fire safe. To ensure safety, it is worth considering the garage boilers of domestic manufacturers. They are characterized by a longer burning time, which increases the battery life. The copper of long burning is characterized by efficiency, durability. The only drawback of the system is the need for constant monitoring.
Homemade potbelly stove can be an alternative equipment. They successfully use second-hand lubricating oil. Development is settled and filtered. Such equipment adds not only heat, but also a specific smell. Many believe that for the garage is an insignificant moment.
Variants of equipment operating on diesel are commercially available.Diesel - air heaters consume a glass of fuel per hour. When this develops heat transfer up to 2 kW. There are more powerful equipment options.
Heat guns are used not only for the garage, but also for industrial premises. Some models can operate on solid fuel or from electricity. The cost of models on the market varies depending on the types of fuels used. You can buy a kit that runs on different fuels.
If there is electricity in the garage, then an electric boiler can be connected to it. This equipment is quite enough for heating the garage, since the premises of this type are usually small in size. Electric heating is reliable and compact. It does not require the construction of the chimney.
Electric heating options may be as follows:
- fan heater;
You can choose one or another method depending on how long a person is in the garage room. For example, with a rare visit, a pair of fan heaters will suffice. With a long stay in the garage you need to consider options for convectors or radiators.Devices of this type of craftsmen are made by hand. For example, for electric radiators enough pipes of suitable size, as well as heaters. The equipment is on sale, but it will have to spend money on it.
The electric boiler is a complex system. It includes the pipelines and the boiler itself. Electric boilers on sale are induction or electrode. The first option is expensive. However, according to the owners, the costs fully justify themselves over time.
Electrode boilers are cheaper in cost, but equipment performance is lower. For electrode equipment need antifreeze. At the same time, not every “non-freezing” is suitable for a specific device.
On sale there are appliances suitable for heating a small garage. For example, infrared heaters. The equipment is characterized by the fact that it heats objects, then objects give off heat to the surrounding space. IR devices consume a lot of energy, so they are considered not very economical.
Oil radiators operate on the principle of a conventional convector. The equipment is able to quickly heat a small room, at a cheap price.
Heat fans with ceramic elements also serve as a heat source. The cost of devices is high, but they have a lot of positive characteristics due to the increased heating area.
Heating the garage with autonomous electrical appliances is convenient, since the devices do not require professional installation. They can be connected to a simple outlet, so you do not need coordination with the organizations that provide power. In addition to the garage, these devices can be used in other outbuildings, for example, in greenhouses. Among the shortcomings, it is worth noting the rapid cooling of the air after switching off the device and the impossibility of heating the garage in the absence of energy.
You can heat the garage with batteries with a circulating pump. Connection diagrams are possible with the boiler, as well as without it. The system is usually connected to electricity and is heated by a coolant, which uses water circulating in a closed profile of pipes.
Heated pipes with hot water give off heat to the surrounding space. Water heating is laid in the garages, which are adjacent to the house.This option is also considered the most suitable for garage complexes. Pipe laying is quite an expensive event. Those who have enough income, use water-heated floor in a private garage. It is convenient, fireproof. You can save money with the installation of water heating in the garage using a conventional stove, a pump connected to radiators. For self-installation, this system is complex, it requires knowledge and skills.
Air heating - economical and efficient in winter.
Any way - profitable and economical. Properly installed air heating of the garage creates comfortable temperatures in the most visited places of the room. Thermal energy is delivered to workplaces through pipes and ducts. For the distribution of warm air used tees, regulators, and more. A popular scheme can be considered in more detail.
So, the system will function thanks to the heat generator. The device must be equipped with a temperature sensor. The equipment is installed in the garage, reliably protected from drafts.Thermal insulation materials will eliminate the leakage of heated air.
Installation of air ducts is carried out under the roof of the garage. At the heart of the highway is galvanized steel insulated. Separate pipes are interconnected by a certain method and connected to the boiler. Functionally, this type of heating creates a directional stream of warm air. Equipment for such systems is considered to be fireproof. Air heating in the garage is easy to install yourself. It should be borne in mind that convectors are usually mounted in a wall and work on the principle of air conditioning. And the steam ovens in the process of working suck the cold air into themselves, and emit it already heated. And to that, and to other equipment, you can connect the system of guide pipes.
It is also worthwhile to consider in more detail the option of heating the garage with appliances working on working out. Furnace waste oil or antifreeze can be highly efficient units. Devices are factory or homemade. Both options are popular because they are characterized by a simple principle of operation.
Such stoves are very often used in car services and garage boxes,as devices simplify the disposal of waste resources. Although the furnaces are not cheap, their further exploitation does not incur any expenses. So the cost of fuel pays off in just a few months of active use.
Store samples of such stoves include a pyrolysis combustion chamber. The package also includes a fuel tank, the capacity of which is enough for a day of continuous operation. The fuel in the production stove burns without the smell of burning oil. Also included is an afterburner and upper ring for the construction of the chimney.
Variants of more expensive furnaces are different droplet combustion scheme. The fuel consumption in the system is lower, and you can use almost any oil, even domestic oil. Drip dispenser provides a constant long-term burning of a certain power.
The stove is kindled by adding burning rags or rubber to a special bowl.
The first and second types of structures craftsmen embody independently. The assembly sequence of a homemade stove is quite simple.
The first chamber is being assembled - it is a round device, closed by a lid with drilled holes.A pipe is installed inside the device - the second chamber of the furnace. A metal bottom is welded to these parts, and a cover is installed. The tank joins a pipe. A portion of the inner tube is welded to it. A chimney is welded to the top of the perforated pipe.
Such a stove can be installed on a flat platform made of non-combustible materials (brick, concrete). Mineral or synthetic oil can be used as a fuel. It is strictly forbidden to use gasoline, kerosene, as well as solvents.
Drip type stoves in home production are equipped with two tanks. In one, there is a burning process, and in the other a combustible gas accumulates. In the second chamber, combustion also occurs, so these stoves give a higher efficiency in comparison with the first option.
In addition, drip-type furnaces are supplemented with elements of equipment that allows you to connect the stove to the tank. It can heat the water or cook food.
The simplest version of the installation of a similar design - from a gas cylinder.
It is divided into four zones:
- mixing zone;
- pyrolysis zone;
- combustion zone;
- post-combustion zone.
In this case, the upper and lower zones are cameras. Both are connected by a pipe that is installed inside. To the top of the cylinder is mounted chimney. Everything, a simple standalone device is ready.
Heat in the garage will be, if you choose appliances that run on gas. However, for some devices, it is not necessary to have a central gas pipeline passing nearby. Gas powered devices are simple and inexpensive. For example, the simplest is the burner.
The device needs liquefied gas that heats the heat exchanger. Heat comes from it, and the movement of warm air is provided by a fan. The burner can quickly heat a small room in which repairs will be made.
The gas heat gun will show itself more effectively on a larger area. Auto-mechanics willingly use equipment in large repair boxes, despite the fact that this device is quite noisy.
On sale you can find portable devices that run on gas. The devices are supplied complete with automation, besides with special gas cylinders, which exclude the violation of fire safety.Devices proved to be effective not only in garage boxes, but also as home equipment.
Recently, catalytic heat exchangers have become widespread, in which a liquefied gas mixture enters the heating element. The panel heats up, giving heat to the room.
Another option for gas-powered appliances is gas convectors. The equipment is powerful enough to heat not only a small garage, but also a warehouse.
Heating devices of this type are of two types:
- Open performance. The devices have an observation hole on the front side that allows you to observe the flame.
- Closed execution. The equipment is usually mounted in a wall, and looks like an electrical device.
Choosing this or that type of device it is important to understand that it must be fireproof.
The safety of any equipment is, first of all, compliance with the rules of operation. Different types of devices meet certain standards. If you combine them into a single whole, then the most secure will be electrical equipment.
Heaters on gas with a balloon or a register still carry a great danger during operation.
Electric heaters of any kind require:
- Compliance with the possibilities of outlets and the connected electrical network to the garage. It must withstand the power of the device.
- Compliance with humidity indicators. In the garage should not be damp. This phenomenon, for example, can occur with a sharp transition from negative to positive temperatures.
Gas diesel, gasoline and other types of heaters must comply with the following standards:
- to be absolutely tight, otherwise any leakage of liquid fuel will lead to fire;
- to be equipped with a chimney, otherwise there may be poisoning by combustion products;
- be equipped with a ventilation system, otherwise there will be a shortage of oxygen in the room.
If the basis of the choice of the device to lay safety, it is better to prefer electrical options. If the basis of choice - the price, then choose diesel units.
Tips and tricks
Experts advise to choose a heater for the garage in accordance with the capacity. The larger this indicator, the larger the area the device can heat. To calculate approximately the required power, it is recommended to calculate the area of the room and multiply the resulting figure by eight.
The result will be approximate, as for accurate calculations there is a special formula that includes such indicators as power (kcal / h) (N), volume (cubic meters) (V), temperature difference (outside and inside) (dT), warm air dispersion coefficient (K), for which the following values are accepted:
- 0.6-0.9 - in the presence of thermal insulation;
- 1-1.9 - while insulating the garage door and concrete walls;
- 2-2.9 - in the absence of insulation and concrete walls;
- 3-3.9 - with metal gates and walls.
The formula is as follows: N = V * dT * K.
The calculation for the garage 7 * 4 * 3 meters, insulated from all sides and with an exhaust hood will look like this:
V = 84 cu. m
For example, at a temperature of minus 20 degrees in the garage should be around zero, then dT will be - 20. For a heated garage, K will be equal to 1.5. We consider:
N = 84 * 20 * 1.5 = 2520 kcal / hour.
To convert the value to W, we will solve another example, since 1 W = 0.86 kcal / hour or 1 kcal / hour = 1.163 W, so our value in BT will be the following - 2930, 76. A heater of such power will heat the room to the set temperature for an hour. By the way, the price of devices is closely related to power.
Secondary values are functionality and country of origin. As a functional, for example, there may be regulators, as well as an elementary system of safe automation.
For example, the simplest oil heaters with a capacity of 2900 W will cost 3500-4000 rubles. Devices with more power will cost about 5,000 rubles, but with exactly calculated figures you should not overpay.
If finances allow, it is better to choose models of equipment working on gas with a closed type of combustion chamber. Devices with power up to 4W can be bought at a price of 12,000 rubles. More expensive diesel equipment of the same capacity. Devices can be purchased at a price of 28,000 rubles.
Quickly and cheaply, you can assemble a device of the required power with your own hands. To make the equipment, you will need pipes, radiators and other parts. This is also a waste, but also labor costs, as well as the obligatory availability of skills. Otherwise, it is better to make the necessary calculations and see the economic benefits of buying a factory heater. These devices will be much more reliable.
