All about heating your home with wood

[ad_1]

Heat­ing a house with wood, despite the pres­ence of many oth­er types of heat­ing, does not lose its rel­e­vance today. Most often, they resort to it in the absence of a gas pipeline. This type of heat­ing is com­mon­ly used in rur­al areas. Quite often, wood heat­ing is used to heat pri­vate and coun­try hous­es, cot­tages and garages.

Advantages and disadvantages

There are many advan­tages to heat­ing with wood. The main thing is their low cost. It is low­er than the price of gas or elec­tric­i­ty. More­over, even wood­work­ing waste can be used for this type of heat­ing. More­over, by no means all the set­tle­ments of our coun­try are gasi­fied. This is espe­cial­ly true for vil­lages in rur­al areas. Heat­ing with logs is also great for sum­mer cot­tages.

An impor­tant fac­tor when choos­ing heat­ing with wood is the envi­ron­men­tal friend­li­ness of this fuel and the com­fort that it allows you to feel. This is not only warmth, but also visu­al plea­sure from the sight of burn­ing wood in a fire­place or in a stove equipped with a panoram­ic trans­par­ent screen, which is usu­al­ly built into the fuel load­ing door.

Heat­ing with wood also has dis­ad­van­tages. The first is the lack of automa­tion. After all, the fuel will have to be loaded into the stove, boil­er or fire­place with your own hands, and this takes a lot of time and effort. In this, heat­ing with logs is sig­nif­i­cant­ly infe­ri­or to gas and elec­tric heat­ing sys­tems. After all, they can be oper­at­ed prac­ti­cal­ly with­out human inter­ven­tion.

In advance, you will need to take care of the avail­abil­i­ty of a sup­ply of fire­wood. You can buy them or make your own. In addi­tion, if the area of ​​u200bu200bthe house is large, you will have to addi­tion­al­ly use radi­a­tors, since it is unlike­ly that it will be pos­si­ble to achieve good heat­ing with just a fire­place or stove. Espe­cial­ly in win­ter. It is best to use a boil­er with a water cir­cuit.

Despite the fact that fire­wood is afford­able for every­one, you will need to spend mon­ey on installing a stove, boil­er or fire­place. And this “plea­sure” can­not be called cheap. You will also have to mount all the addi­tion­al equip­ment that will be required to heat your home with high qual­i­ty.

Proper production of wood heating

Mod­ern wood fuel heat­ing sys­tems have sig­nif­i­cant dif­fer­ences from pre­vi­ous­ly used schemes.

Atten­tion: Brick stoves, which act­ed as a heat exchang­er, trans­fer­ring the gen­er­at­ed heat to the room, were replaced by mod­ern fire­places, boil­ers and stoves.

*
The choice of heat­ing device depends on the avail­abil­i­ty of space for instal­la­tion and the area of ​​the build­ing. When choos­ing a wood heat­ing sys­tem, you need to pay atten­tion to the fol­low­ing fac­tors:

  1. Ther­mal pow­er of the device. It depends on the area of ​​the house, the degree of its ther­mal insu­la­tion and the cli­mat­ic zone in which it is locat­ed.
  2. The need to allo­cate space for a boil­er or fur­nace. The device for heat­ing with wood fuel must be installed in a room spe­cial­ly des­ig­nat­ed for this pur­pose, which must meet cer­tain require­ments. In par­tic­u­lar, have sta­ble ven­ti­la­tion.
  3. Avail­abil­i­ty of stor­age space for fuel. Wood must not be stored in a room where a stove or boil­er is locat­ed. They must be stored sep­a­rate­ly.

To deter­mine the device that is best suit­ed for heat­ing with wood, you should take into account the para­me­ters of the build­ing and your finan­cial capa­bil­i­ties. As prac­tice shows, the most pop­u­lar and effec­tive option is to use a dou­ble-cir­cuit boil­er with a water cir­cuit in a pri­vate house. It will allow not only to warm the build­ing with high qual­i­ty, but also to always have hot water at hand. But in order to make the final choice in favor of one or anoth­er device for heat­ing on wood, you should con­sid­er each of them in more detail.

Wood heating options

In order for the house to be warm, you should choose the right wood-burn­ing heat­ing of a coun­try or pri­vate house that will be used. As already men­tioned, a stove, fire­place or boil­er can be used for this pur­pose.

Atten­tion: When choos­ing, you should start from the num­ber of rooms and the area of ​​u200bu200bthe build­ing.

Usu­al­ly, if the house is small, a stove or fire­place is installed. Oth­er­wise, it is bet­ter to install a boil­er with a water cir­cuit. Let’s take a clos­er look at each option:

  1. Fur­nace heat­ing is char­ac­ter­ized by high effi­cien­cy and a small heat­ing area. But at the same time, it is the eas­i­est to install. Fur­nace heat­ing is suit­able for build­ings up to 60 m².
  2. Water heat­ing includes a boil­er (fire­place, stove) with a pipeline con­nect­ed to it. Ther­mal ener­gy is trans­ferred through radi­a­tors. This heat­ing option is good for build­ings over 80 m².
  3. Fire­place heat­ing is in many ways sim­i­lar to stove heat­ing. The main dif­fer­ence is in a more capa­cious com­bus­tion cham­ber. In some cas­es, such a boil­er may have a hob.

The heat­ing sys­tem using wood­en logs can be sig­nif­i­cant­ly improved. For exam­ple, a heat exchang­er can be installed in the fur­nace, which will allow you to cre­ate a full-fledged water heat sup­ply.

But most often, a wood-burn­ing boil­er is used to heat the house. It is much eas­i­er and more prac­ti­cal to use than a stove or boil­er. In addi­tion, it can be made inde­pen­dent­ly.

Making a wood-fired boiler yourself

Mak­ing a wood-fired boil­er with your own hands is not at all dif­fi­cult. You just need to choose the right grade of steel. Its thick­ness must be at least 1.5 mm. The boil­er is rec­om­mend­ed to be made by weld­ing. But since it takes a lot of time, steel bar­rels with the desired wall thick­ness are often used.


*
It is best if the bar­rel capac­i­ty is 200 liters. It must be cut along, and inside to make a par­ti­tion. This will be required to install the wheels. A hole is made on the end part for mount­ing the door, which is rec­om­mend­ed to be select­ed in advance. You will also need a chim­ney with a diam­e­ter of not more than 10 cm. It is locat­ed on the reverse side and serves to remove car­bon monox­ide.

But if you intend to install a heat­ing boil­er made by your­self, you should be aware that it has some dis­ad­van­tages. First of all, it is low effi­cien­cy and short ser­vice life. In addi­tion, if you acci­den­tal­ly touch its sur­face, you can get burned, as it gets very hot.

A hand-made wood-burn­ing boil­er is per­fect for heat­ing var­i­ous out­build­ings with a small area. For exam­ple, barn, garage, etc. If you need to heat a coun­try or pri­vate house, it is best to install a fac­to­ry mod­el, which will be of much bet­ter qual­i­ty and will allow you to heat the build­ing well.

Arrangement of the boiler room

Wood heat­ing of a coun­try house implies the allo­ca­tion of a room in which the boil­er and devices for its con­trol will be locat­ed. This room must meet the fol­low­ing para­me­ters:

  • the pres­ence of a smoke chan­nel with a height of at least 4 m;
  • area not less than 6 m²;
  • the pres­ence of com­bined light­ing;
  • ceil­ing height not less than 2.5 m;
  • pres­ence of forced ven­ti­la­tion.

Atten­tion: Room dec­o­ra­tion should be made of fire-resis­tant mate­ri­als. If the boil­er has elec­tri­cal com­po­nents, there must be a pow­er sup­ply line.

What kind of firewood is best to use

Much for good heat­ing depends on what kind of fire­wood you use. It should be tak­en into account that the spe­cif­ic heat trans­fer of this type of fuel is much low­er than, for exam­ple, gas. For fire­wood, the heat trans­fer is — a max­i­mum of 17.4 MJ / kg, and for gas — 31.8 MJ / kg. More­over, to main­tain the desired tem­per­a­ture, logs should be reg­u­lar­ly thrown into the oven.

There are two ways to increase the time between down­loads:

  • heat­ing with wood, which emit the most heat;
  • instal­la­tion of a fur­nace or heat gen­er­a­tor with a large com­bus­tion cham­ber.

In the lat­ter case, it should be borne in mind that the vol­ume of the com­bus­tion cham­ber of boil­ers is much larg­er than that of fur­naces. Also, stoves are char­ac­ter­ized by slow­er heat­ing, dur­ing which you will often have to throw fire­wood. But then, you can enjoy the heat, as the fuel will burn quite inten­sive­ly and this will be accom­pa­nied by a large heat trans­fer.

Much depends on the wood you use. Ash, horn­beam and oak are dis­tin­guished by the great­est heat trans­fer. Their burn­ing tem­per­a­ture is about 1000 degrees. In addi­tion, they give a strong heat. The worst fire­wood from poplar. Their com­bus­tion tem­per­a­ture is less than 500 degrees, which means that the con­sump­tion of fire­wood will be greater, and the heat trans­fer will be less.

Atten­tion: Since ash and oak are quite valu­able tree species that are used to make var­i­ous fur­ni­ture, doors and var­i­ous oth­er things, it is best to use birch or white aca­cia for heat­ing your home. Of course, if these types of trees grow in your area.

Much depends on how dry the fire­wood is. After all, if they are wet, then the heat trans­fer will be min­i­mal. This is due to the fact that most of the heat gen­er­at­ed is required to evap­o­rate mois­ture. If you buy fire­wood, you should care­ful­ly check its dry­ness. And if you har­vest them your­self, the fire­wood should be dried well. This is the only way to achieve high-qual­i­ty heat­ing with a rea­son­able con­sump­tion of fire­wood.

Do-it-your­self wood-burn­ing heat­ing of a pri­vate house allows you not only to save a lot of mon­ey, but also to effec­tive­ly heat the build­ing even in severe frosts. It will not be dif­fi­cult to make a stove, boil­er or fire­place on your own. But it is best to pur­chase a fac­to­ry prod­uct, as it will be of bet­ter qual­i­ty and will last much longer. Of course, this sys­tem is not with­out some draw­backs and, for exam­ple, is infe­ri­or to heat­ing with gas or elec­tric­i­ty. But still, the demand for wood-burn­ing boil­ers, stoves and fire­places is still great. These devices are indis­pens­able for high-qual­i­ty heat­ing of hous­es in rur­al areas in the absence of gas sup­ply there.
