Electric heating is the simplest and most efficient way to generate thermal energy thanks to its 99.99% efficiency and the direct conversion of one type of energy into another through the use of electric heating elements. But at the same time, this method is also one of the most expensive, yielding in energy costs only to liquid fuels and lubricants, such as gasoline, diesel fuel, and oil.
Gas boilers are positioned as the second popular source of heat. Of course, they are good for everyone, with the exception of one nuance — not everywhere there is the possibility of connecting to a gas main, and the cost of such a connection amounts to many tens of thousands.
Therefore, there is no doubt that the majority of people who have country residences are concerned about the problem of heating their homes with the lowest monetary costs for both equipment and energy.
How to organize the heating system of a house in which there is no electricity
The most promising heating system in conditions of limited access to blue fuel at present is solid fuel boilers, which are both purely wood-fired and designed for a wide range of combustible materials, which significantly expands the range of applications. A separate subspecies are the combined boilers of the firewood / electricity, firewood / gas, gas / electricity and other combinations.
However, of significant interest, for complete independence from centralized supply and the ability to implement heating without electricity, are precisely simple solid fuel boilers that do not require electricity, gas or anything else besides the main fuel for their operation.
Types of boilers that do not require a power supply network
There are not so many types of equipment based on design differences. There are much more devices that differ in the type of fuel:
- Coal and coke.
Of course, now there are combined boilers that digest any kind of combustible materials with the same diligence, but they are usually quite expensive, complex and do not have such technical perfection as instances that use one thing. Yes, and most of them require electrical power, otherwise the boiler will turn off, and the heating system will stop working.
Therefore, the range of devices is significantly reduced, which greatly simplifies the selection process:
- Purely mechanical boilers.
- conventional ovens.
Due to the difficulties in installation and operation, only boilers are of interest, which do not take up too much space, have a fairly high efficiency, are reliable and can be easily integrated into any heating system using standard tools.
The main difference from electronic counterparts with microprocessor brains is the lack of the possibility of fine tuning the system parameters and automatic control. On the one hand, this is a minus, and on the other, a plus. Minus — because it is inconvenient and all manipulations have to be done manually, not forgetting to independently control all indicators. The plus lies in exceptional reliability — there is practically nothing to break in a mechanical boiler and the heating of a private house without electricity is carried out smoothly. Unless a manufacturing defect can overshadow the joy of enjoying warmth.
Features of installation and operation
Features of the installation of stoves and fireplaces should not be considered — this is a whole science. This process is not something to repeat, but even to control an inexperienced person will not be able to do it. Therefore, we restrict ourselves only to such more or less standardized devices as solid fuel boilers.
First, and most importantly, the boiler must have a separate room, which is isolated from living rooms.
Second — draft and ventilation should always be in perfect order. Carbon monoxide poisoning occurs very quietly, and statistics say that 85% of accidents are fatal.
Thirdly, the quality of the fuel plays a decisive role. In order to achieve passport characteristics, you need to feed your friend only high-quality food. The main parameters are ash content, calorific value and humidity. Wood moisture content of 10 and 20% gives a difference in the generation of thermal energy up to two times. Therefore, from one cube of dry wood you can get as much heat as from two cubes of wet wood. There is a difference in money.
The fourth follows from the third — a place to store fuel supplies. It must be dry, ventilated and easily accessible — you still have to carry firewood there. Or bags of pellets/charcoal.
Therefore, heating a house without electricity will force its owner to work physically and require a certain amount of attention to the process.
Tips & Tricks
- If the boiler is pellet, then it is better to purchase a copy with a large volume of the fuel bunker, which will reduce trips with a shovel to the boiler room to load fuel.
- In places remote from civilization, or with difficult access roads, a boiler oriented to the use of firewood will be more preferable. Because no one will be able to bring a couple of hundred kilograms of pellets to the customer along a snowy or flooded road, which are the only ones suitable for the boiler. Firewood is always in abundance can be found around the house.
