How to make firewood heating in a private home: variants of the device with air and water circuits

In anticipation of a cold time of year it is very important that the house was warm. In modern life, there is a large variety of ways for home heating, and each year this list is expanding thanks to new technologies. But the usual methods still in vogue and we have not lost relevance. For example, a furnace heating method, based on the water circuit - proven generations. In fact, this method is combined and is based on the furnace and water heating mode. This article will help you understand how to build their own heating systems using this scheme and detailed guidance.

Specificity of the heating system

Standard oven heating method unevenly distributes the heat, the main heat mass around the furnace itself, but the further away from it, in order to be colder. But the presence of the circuit will provide an opportunity to distribute the heat throughout the residential premises. And with a single oven, you will be able to heat all the rooms in the house. The furnace also heats the walls and flue that is just as important at Ardagh. Employment of this method is based on heating coal-fired boiler principle, except for the water circuit and the substance used for heat transfer.

Backbone of this structure is the detail of the coil, which is part of a heat exchanger, which is connected and the rest of the chain.

Benefits stove heating

You do not need to make expensive acquisitions to assemble the unit, as the components are highly accessible.
Longevity life time work. And in the course of service required to carry out non-essential exterior renovation, ie cosmetic improvements. And it is much more profitable service in the specialized service of modern technology.
The design of the finished mechanism make unique as the parameters of the construction, which are suitable to decorate and after the oven on an individual project.
In comparison, an improvised method of heating and conventional heating boilers, wins the first, as it contributes to heat not only the coolant but also chimneys. When operating such a system transmits heating to radiators. Even if you stop to heat, the furnace will be a long time to heat the room until it has cooled completely.
In addition, you can plug in a heating oven for even cooking. A heat exchange element can be integrated in the existing mechanism.

heating system shortcomings with water jacket

It occupies a large amount of free space. If mount design it is necessary to consider this factor. And if you improve an existing inserting a heat exchanger unit, you have a lot of time in adding fuel to keep heating during the day.
Reduced safety against fire. Fireplace or stove involve storage of fuel in the immediate vicinity, which means that can not be left unattended for a long time.
If there was a tab with an error dimootvoda, the living room will be filled with carbon monoxide. What is just as dangerous to human health.

For your information! If you decide to build this type of heating in a country house, where you are not present in winter constantly, to fill the unit, use antifreeze liquid, so you will avoid peremerzaniya pipes.

principle of operation

Working principle of the heating furnace with water jacket uncomplicated. Water enters the heat exchange element, which is located in the furnace, the heating is due to the combustion of fuel. Then to circulate hot water heat passing through the radiator, giving heat. Passing round the chain, cooled down, water is again returned to the oven.

Assembly and connection of heat equipment

If there is even the initial design skills, you can collect the furnace for heating circuit on their own, especially if you are able to experience in bricklaying or settling furnace. You should start with the preparation of the heat exchanger, as it is the most important part in the whole mechanism. You can purchase it in one of the specialty stores, or make your own hands, using pipes and iron sheets. Creating a product yourself, you can give the desired shape, given the characteristics of the room space.

Information! Since the system is complex, it is better to entrust the design of proven professionals in order to avoid situations threatening the lives of people in the living room, if you are not competent enough in this question.

heating system can be done in two ways:

create the entire chain, starting with the installation of the heat exchanger;
embedding the coil in the existing system.

The second option is more difficult, because you need to partially disassemble the structure. And the installation of parts will reduce the volume of the furnace.

Mandatory conditions when mounting

The water level in the construction of the heat transfer element must be higher than 4 cm, otherwise it will boil and this is unacceptable.

The water level in the construction of the heat transfer element should be greater than 4 cm

The coil should be not less than 5 mm thick. If you use for burning coal, the wall should be even thicker, otherwise they just burn through.

Observe the installation distance from the walls of kindling. Leave for at least 2 cm, this distance will be enough, given the expansion upon heating coil.

With extreme caution Treat pazharoopasnosti entire structure. Inside the oven should be the distance between the timber walls and partitions, since these parts prostnoe tangency facing ignition. Optimally to make the finish brick or other refractory material.

Heating furnace exchangers

In the diagram below illustrates one type of coil. It is optimally suited for heating and cooking systems, as on top of it can easily accommodate a plate for cooking.

To facilitate the creation of part of the process, you can make some changes to the design, namely to replace the U-shaped tube at the top and bottom of the profile. Among other things, if needed, can replace conventional pipe rectangular profiles.

If the furnace is not the setting of the cooking surface, the best option would be to put a few tubes in a horizontal position, it significantly raise the level of efficiency. Depending on the layout and equipment of the water circuit, to mount the device to display or water treatment can be anywhere.

To construct a coil of sheet iron

Plast metal should be at least 5 mm for this element. When collecting the same profile is applied 60 * 40 mm tubes and 5 mm, they are intended for output and water water mass. The total size of the device depends on the length of the fuel of the stove.

If eventually the element will be integrated in the boiler-heating system, the best solution would be to to make the gas warmed the shelf and leave the coil in the flue channels, which will be located in front of exchanger. When this calculation is easy to put the cooking surface.

Also detail can be made in the form of a book, when you combine the extreme panels tubes or profiles. But with such a construction of the upper shelf is missing. A need for optimal permeability supply connecting pipes at the top. Come out to better organize the back of the heat exchanger or on the lateral side.

In such a construction better placed immediately above the hob register.

Getting to the circuit assembly

Picking construction going on in the same way as in other Ardagh systems. Do not forget to include a caveat, in this type of heat, returns an array of water enters the furnace level above.

Movement of the thermal mass at such a heating may be of three types:

Natural - provides for the installation of pipes under the largest angle that can be done. The docking tube furnace zone and need to construct booster portion, for this purpose it is sent up to 1-1.5 m, and then send down to the batteries.
Forced - up at 30% efficiency. In preparing the plan is necessary to provide a pump that will give the right pressure. However, heating is not recommended for use only this type of circulation, as during a power failure or pump failure, the vehicle comes to a boil and the mechanism will arise.
Combined - provides for connection of pipes of the first mounting point with electric pump, which need to be connected into the structure as shown in Scheme 4. This combination will allow the pump to operate from the power supply, and in the absence of current, the movement will continue within the system naturally.

construction assembly

This stage is usually best left to a professional, for the reason that in the absence of any experience in this field correctly assemble the construction will not work.

Consider the total area of the house, since the value of the unit depends on this. Note that if the construction weight above 750 kg, before installing it is necessary to establish a foundation. Before installation on a foundation of sand prosypku do, it will perform the function of thermal insulation, it is important to provide for the safety rules to avoid fire.

Described in the article method of heating, reliability and durability, not to mention the fact that it is not expensive. Installation also requires a large investment of money. Also, try yourself as a designer and make this an attractive element of the interior attraction.

Next offer available to video creation with the method of the furnace brick with connecting the water circuit.
