As one fireplace to heat a two story house

But year on year is not necessary — it is summer, more like autumn, and summer visitors are living in different climatic regions. Well, the end and the beginning of the season at all different — someone finishes the gardening business since the beginning of the school year, and the other is guided by the first snow. Therefore, the source of heat in the country house can not hurt, even if it's just a summer cottage.

One of the options of heating in a not too hot time device fire. In this article I want to tell you about the structure of the fireplace heating in one suburban house.

 

The real story of one of heating of a country housethe Owners of this house in a holiday village near St. Petersburg started the holiday season earlier — in March-April. At this time in the North-West confident of snow. And went to town with the new snow, in November. The presence of heat in this mode of operation of the country house — a prerequisite.

The main gas in the village was not, square footage is not allowed to install the gas tank (gas storage tank), use bottled gas for the calculations of the owner was not economical. The number of kilowatts allotted for the house was insufficient for the device of system of heating on the basis of the electric boiler or using space heaters.

Selection of the heater is narrowed to solid fuel boiler or furnace heating.

The option of the boiler did not come, because it was assumed that mainly in the house to live in mother-in-law with their grandchildren, and the old woman is difficult to cope with such a heating technique. The traditional oven was too bulky for a small house.

In the end the choice fell on the fireplace, and the customer was interested in the question of whether to only use it for heating small frame country home in the period from early spring to late autumn. Besides, solving the problem with the heating, we can obtain the decoration living room — fireplace, near which you can gather for winter family holidays.

The fireplace as the heaterso by the fireplace, followed to find out whether it will fit as the solution of the task. A fireplace as a heating appliance? And why not.

 

Although in recent years the fireplace from completely utilitarian heating device, which he has traditionally been, for example, in England and European countries (Russian preferred furnace), is rather a design "thing" in the interior, plus a demonstration of the wealth of the owner. Most often the fireplace is pretty expensive, and in some cases can become a true luxury item, the cost of which is comparable to the price of a dacha in a prestigious area.

Modern fireplace can easily perform different functions: you can only be a great decoration of the interior (e.g., fireplaces) or, in addition to decorative role, to serve as a source of heat. The main thing — to choose the right model and perform the installation based on the needs.

Types of fireplacesas this article is about the fireplace as the heater won't waste time on the examination of purely interior options and decorative way to design the outer part. Let us turn the attention to the combustion part.

  • traditional English fireplace
The English fireplace is the fireplace with an open rectangular firebox. Fireplace Rumford — enhanced variation of the classic English fireplace, the furnace has a trapezoidal shape. From the point of view of heating is the least efficient device: its efficiency is usually very low: from 5% to 20%. An open fireplace allows you to adjust the strength of combustion, the hearth burns a lot of fuel, giving a strong heat in the process, and cools down quickly when the active burning ceases.

  • modern indoor fireplace
Today, consumers often choose fireplaces enclosed type — having a tight-fitting door with fireproof glass. The door allows more economical use of fuel. In addition, advanced models have built in valves for regulating the intensity of combustion. Some furnaces manufacturers claim that the efficiency of their products reaches 85%.

Of course, they are evil: the coefficient of performance for devices operating in such an unstable fuel like firewood, the concept is very subjective. Efficiency fireplace or a stove depends not only on the device itself the furnace, but grades of wood (hot birch, oak or larch, or so-so the wood is alder or poplar), from their moisture and other things.

 

Fireplaces closed: many different, but all good?Modern versions of the fireplace is a metal box, furnace or fireplace cassette factory performance with a tight door equipped with a glass and adjustment knobs (various valves, podduvalom, dampers). A nozzle for connection to the chimney. The chamber of the furnace may be cast iron or steel lined with chamotte plates.

Depending on model, the furnace can be equipped with a smoke box different design, the camera of the second afterburning, thermal sleeve, convective channels, a circuit for the device of system of water heating and other necessary and useful adaptations that increase the efficiency of your appliance and usability.



In addition to fireplace inserts and fireplace cassettes, there are still stoves, caminetti (self-contained fireplace inserts that do not require additional decorative frame), simply just stoves and fireplaces.

That is, in addition to the traditional furnace products designed and built by a master Builder from the bricks on-site, offered a good ready-made options, made in a production environment, using modern engineering solutions.

Learn more about the structure of the fireplace inserts and the throes of choosing the very best furnace, fireplace or furnace it is necessary to write separately. Here I want to tell you about the option that was chosen for this particular project.

 

The Swedish view of the heating devicesto solve the problem — the organization of heating by means of one of the fireplace, chose the products of "Keddy". Sweden is a Northern country, and what a warm house Swedes understand perfectly. The Scandinavian company more than forty years has been designing and producing cast iron fireplace magazines and other furnace equipment.

At the time of construction of the fireplace this country house, more than a decade ago, the company's products "Keddy" was one of the most efficient in terms of heating. In our country today on the market there are many other proposals. But the magazine "Keddy", in my opinion, continue to be the leaders among heating appliances. For the study of the country house, choose the model Keddy SK 203.

Fireplace cassettes produced by this company are of the one-piece housing of high quality cast iron. Cast iron is the best material for the manufacture of the furnace, as it has high conductivity. Cast iron fireplace insert will allow you to heat the room to a third more effective than steel counterparts.



Cast iron is more suitable to work with high temperatures from heating of the outer casing of this alloy is not subject to deformation. And among other similar products Keddy fireplace cassettes stand out for their quality and manufacturability.

Cast iron fireplace insert Keddy is very correct geometry even in doors not sealing asbestos cord, which eventually breaks down and requires replacement. The doors are so precisely made and have thoughtful design that closes tightly even without additional seals.

The furnace of Swedish production have one of the highest efficiency: manufacturers are talking about almost 70%. Such high efficiency of the device due to applied engineering solutions:

  • monolithic design
The lack of welded or bolted connections increases the reliability of the design. Manufacturers provided the continuous use of the furnace indefinitely long time. This means that it is possible to continuously heat the entire heating season: the factory warranty on cassette twenty years, although the devices are no problem to work much longer.

One-piece cast iron body — one of the main benefits of the cassettes "Keddy". Under high thermal loads, the housing of the fireplace cassette do not warp, and its tightness allows to achieve the combustion whiter high temperature that increases the energy efficiency of the fireplace. Passport magazine SK 203 indicated power of 14 kW.

  • the optimal form
Prismatic shape magazine additionally reflects the heat from the walls inside, which also increases the thermal efficiency of the heater. The outer casing Keddy has a one-piece double wall with air cavity in between. The air between the walls cools the cassette, the heat itself: it additionally protects the design against deformation, it increases the efficiency of the combustion process and improves device heat dissipation.

  • adjusting boost
On the front side of the cassette has a handle to adjust the flow of air entering the furnace for combustion (see the diagram "item 1"). Adjustment allows you to use the tape in two modes: fast, hot burning, and the mode of decay. Wood one tab missing almost ten hours in the slow mode. The adjustment is made by means of two cranks, turning the small valve.

  • preheating of the air for blowing
The air that enters the interior of the cassette for combustion, before entering into the furnace is preheated in the convection channels at the sides of the inside of the case (see the diagram "item 2"). Passing through the channels, air is heated by heat magazine, so the furnace operation consumes less firewood, which increases efficiency. The heated air enters the furnace through the narrow slits along the vertical sides of the cassette situated in front of the glass.

In addition, the heated air entering the furnace, washes the glass, preventing the deposition of soot is called a "clean glass"system.

  • high fin heat exchanger
On the cartridge housing top rear and on the inside of the cassette is made of cast-iron ribs that increase the heat transfer unit.

  • camera second afterburner
Fireplace "tooth" forms a second chamber for afterburning. Products of combustion are not immediately sent up the chimney: resting in the fireplace "tooth", the smoke enters the chamber of the second post-combustion, where the burning down of particles not burned in the main furnace. Thus, first, saves fuel, and secondly, additional heat is released, increasing the efficiency of the heat transfer device, its efficiency.

  • a simple closing mechanism of the door
Impeccably customized doors with ceramic glass close simple and effective mechanism.

 

Diagram of the heating system in a holiday houseso as the primary heat source fireplace chose the tape of the Swedish brand "Keddy" model SK 203. And now about how everything else was arranged, which led to the desired result — the successful heating of the house total area of 90 square meters: living room and kitchen on the ground floor, two bedrooms on the second.

Given that this fireplace was planned the only heating device, chose the model with power reserve. For its calculation usually use the following formula: 1 kW on 10 square meters with a ceiling height of not more than three meters. That is, when the passport value of 14 kW, there was almost a 50% reserve thermal capacity.

 

The heating of the first floor isthe fireplace placed in the living room. This Parking space is due to radiant thermal energy, emitted from the burning fire through the glass doors.



To the heater worked efficiently, in addition to the heat source heat battery: something with a large mass and made of a material with a high heat capacity. One of such materials — clay, and hence the products made from it, for example, bricks. Furnace heating based on the large mass of bricks, is heated by hot gases of combustion products, gradually radiating heat into the room when the furnace is already finished.

In this project, the thermal battery was a brick wall between the living room and kitchen with chimney. Veneer magazine is also brick, in addition to accumulate heat. Heating plate-a partition made according to the principle of dvuhlampovoe furnace around here on such a scheme.



Hooded design, in my opinion, has the advantage compared with the channel furnaces: for a more simple inner structure, easier to clean, i.e., easier operation and increased durability. Ductless furnaces are the best heating at the bottom.

 

The heating of the second floorOn the second floor required a heating of two small bedrooms and a staircase hall. For heating the bedrooms is used the heat produced as a result of convection in the thermal box. The air surrounding the fireplace heated the tape itself is heated and the warm air upwards. The temperature in the heat shield around the cassette reaches 500-600 degrees Celsius.

From the heating duct in the air duct channels the hot air is supplied into the second floor bedroom. The photo shows the stage of installation of the fireplace at the stage of installation of flanges for connection of ducts.

The ducts were removed in the ceilings in the bedrooms. Throughout the route these channels provide insulation for fire safety and prevent losses of heat.

The duct ended with the grids shown in the area of the floor. Is well thought out arrangement of the gratings of air ducts, so they were in places where the heated air could freely exit through the holes, but not on-the-go people, because he can be quite hot.



The result the customer was pleased with — the house was warm even in winter, the family came to the country for the holidays. The use of fireplace cassettes allows you to heat the house in cold weather very quickly, which is important for truckers, going out in the cold from time to time. And the heat shield-battery securely holds the heat.

In addition to this method, there are other options to use a fireplace cassette for heating small country houses: the device is a water jacket and batteries as a complementary source of heat, Underfloor heating-type ondol, and others. The subject of heating is very broad, so one article to consider in detail all the ways. published
