For a new private house, cottage or villa for a good and efficient way of heating equipment will be the heating system "warm floor". Currently existing information suggests that the effectiveness of such a system is its residential heating is effective enough. Water heated floors today are becoming increasingly popular in private households, taking into account the large variety of technical equipment, materials and tools needed for the installation of such a system. Quality of heating in any case depends on the heat source. If gas and electric boilers for installation of floor heating of special questions arise, then a bunch of solid fuel boiler and the heating of the "warm floor", cause you trouble.
The main reason lies in the lack of a clear and effective adjustment mechanism for heating the coolant temperature. The temperature of the boiler water, which diverges along a contour for floor heating, should not exceed the required parameters. The slightest malfunction of the heater and on your floor, right in the room, you can prepare a meal. Consider the problem from different angles.
Warm floor - its effectiveness and compatibility with solid fuel boilers
The main advantage of which has a heated half in comparison with other heating methods, uniform warming up the internal space area. The room, which is equipped with underfloor heating virtually no heat, no cold zones. The heated floor radiates heat. Warm air flows uniformly move upward, forcing an air cooler. By natural convection occurs regular ventilation in heated rooms.
Important! According to its effectiveness Heated floor heating type operating due to a heating device for solid fuels, it is only slightly inferior to the same system operating on the gas-fired boilers.
Due to the fact that the temperature of the coolant in the heating circuit for the warm water floor lower than when convection heating is achieved a substantial saving of fuel resources. In the case of solid fuel boilers, this fact is important. The heated screed is a kind of heat accumulator, which is able to give a long time into the interior of the stored thermal energy. Even when stopping the boiler, heated floors for quite a long time remain warm.
At the proposed video describes in detail and shows the basic technical details and nuances encountered during assembly of the heating circuit.
For those who choose home floor heating by solid fuel boiler heating system, must take into account a whole range of nuances and technical aspects. Competent selection of a heating device for the heating system, correct piping and wiring, will allow you to get the maximum from the expected result of the heating equipment. Solid fuel due to its high inertia represent radiant floor heating system for the "double-edged sword '. On the one hand it is good, when the boiler cools down for a long time and the pipeline continues for some time to enter the hot coolant. This will allow for some time to avoid the rapid temperature drop inside the premises.

On the other hand, quickly reduce the temperature of heating during operation of boilers for solid fuel, it is not possible. The system is difficult to adjust. Requires installation of additional protective devices to compensate for the lack of technological flexibility of the heating equipment, working with wood or coal.
Enumeration of the disadvantages associated with the boiler equipment working with wood or charcoal can be extended:
- the need to regularly download the next batch of fuel (at least not less than 1 times a day);
- cleaning and cleaning of the boiler is done manually, which also takes a lot of time;
- the need to store a particular coal or firewood stock in the vicinity of the fuel assembly;
- regularly check the health and status of the chimney ventilation in the house;
- a sharp drop in the heating efficiency of the system by reducing the boiler power.
On a note: The last item for underfloor heating is not so urgent, remembering about the ability to play the role of a concrete screed heat accumulator.
Despite the obvious difficulties, the water floor in a country house, powered by solid fuel unit has its positive side. In the first place it is worth - autonomy. For a country house this plus the heating system is, if not the most important, is the key. Economy and efficiency of the heater, heated with wood, wood waste, on the coal or fuel briquettes, also is an important aspect that should be paid Attention.
Methods for connecting the solid fuel boiler to the floor heating system
Solution of the fundamental problems
The main problem is that most of the heating devices on solid fuels used in private houses - the absence of the automation to which we are accustomed to exploiting gas or electric units. In most models, the boiler stops carried out in semi-automatic mode, the ash pit closed, the boiler went out. Correspond to a principle of the heating boiler that would be in the house worked effectively heated floors.
Heated floor from a technological point of view is the equipment for which there is a fundamental limitation on the heating temperature. floor overheating will lead to the fact that the comfort of the house will have to forget for a while. Working boiler produces order of magnitude greater thermal energy than is needed to supply the heating circuit. The problem can be partially solved by installing a mixing valve or an electric pump system which circulates the hot coolant through the pipes. However, in this case, the main advantage is lost solid vehicles, their autonomy.
For reference: the recommended temperature of the floor surface in the accommodation should not exceed 29-300FROM. The maximum allowed threshold of 33 degrees in bathrooms, in bathrooms, where flooring is usually made of tile or tiles.
Uncommon in the winter, when bad weather disrupted power supply to residential buildings. In such a situation threatens to stop circulation pump overheating not only a heater but also the destruction of the basic units and elements of the heating system. Restoring power lead to the fact that the superheated coolant will once again flow into the heating circuit which is not capable of withstanding such temperatures. As a result, a breakthrough, and the failure of the whole heating system. What this means, you can imagine!
In order to protect themselves against such trouble, it is better to equip autonomous heating system additional devices for the removal of excess heat. immediately extinguish the boiler will not work and reduce the heating temperature, especially at night, did not immediately succeed. For this work you can perform additional devices.
The process first. Connecting radiators
Important! Without installing a three-way valve (typically 3-8 pieces. according to the number of loops) operation of your heating system will always be under threat. Mixing unit, equipped with three-way valves, able at the right time to solve the problem of cooling the heated coolant.
With access to the heating boiler for underfloor heating, heated with wood, it is sufficient to establish in-house additional radiators. The main task, which is assigned to them, is to compensate for the excess heat coming from the heating apparatus. Hot coolant will circulate freely on the battery, giving extra heat. Usually, for this purpose, put 1-2 radiator in areas which are periodically visited by the inhabitants of the house (the corridor, the basement, Heating Rooms).
The cast-iron battery is fully capable to cope with this role. Cast iron radiators withstand great pressure (superheated steam). The main task during the installation of the radiator, to obtain greater heat transfer area.
On a note: at a temperature of coolant at the outlet from the boiler 45-600Since only the installation of auxiliary radiator reduces the boiler water temperature of 5-8 degrees.
The battery is connected in such a way that the boiler water flowed into it in a natural way. The system, so equipped, able to withstand considerable overheating and does not collapse. In this case, you can do without the expansion tank, if it is a solid-fuel units of small capacity in which the combustion chamber has a small volume.
Method two. Installing the storage tank
If you have a house of considerable size can give preference to a more reliable and efficient option. Heat storage, in other words, large capacity coolant collection copes with heating the coolant temperature controller role.
Important! There also should be mindful of the need to install a three-way (termosmesitelnogo) valve. As a rule, any heating system can not do without such a device.
The proposed scheme demonstrates just how simple and easy to perform the installation of the storage capacitance to the overall heating system.
According to the principle of operation - the thermal battery is the same gidrostrelkoy, only larger. The main problem to be solved by thermal receiver is to select the heat. Operating the boiler will heat the heat transfer fluid flowing in the first holding tank. Already from the storage tank cooled to the required temperature of the coolant will disperse to the heating circuit of floor heating.
Typically the volume of the tank is calculated based on the ratio - 40 liters per 1 kW heater. With such a technique you no longer scary overheating. Due to the storage tank and the efficiency of underfloor heating, you will be able to significantly reduce the amount of fuel in the boiler downloads. The savings there!
Choosing a solid fuel boiler for underfloor heating
Deciding for yourself to create in-house comfort and convenience with the help of solid fuel boilers and heating systems "warm floor" system, it is not necessary to build special illusions. This scheme is so sensitive and gentle in operation, so you will be required constant attention and control to the operating equipment.
In order to somehow simplify your task in the future should be strictly to the choice of the solid unit.
Use the traditional wood-fired unit can only then you will have more time to spend on its maintenance. The situation is better with the boiler equipment, equipped with automated fuel supply mechanism. Good in this respect, solid pellet machines. By setting the pellet hopper next to the heating unit, it is possible to release themselves a lot of time.
For example: a loading hopper, an average of 1-2 m3 fuel in the form of pellets, it allows to operate smoothly boiler capacity 50 kW practically week. The heating system is practically immune to defrost during your long absence.
Balance the shortcomings of traditional solid aggregates allow pyrolysis type boilers.
Even with manual loading, you will need only 1-2 times to fully load the furnace unit. The duration of burning of fuel in the furnace, the presence of a heat storage system, the physical properties of the concrete screed in the complex and provide the desired comfortable temperature inside the premises.
conclusion
In assessing the technical capabilities of solid units with the expectation of the installation in the house underfloor heating, you can draw the following conclusions. The technical solution in this case is viable. Solid fuel boilers with under-floor heating can provide the expected effect if a responsible approach to solving problems and not to save on materials.
It should be noted that the system of floor heating works better with the boiler equipment on solid fuel, when the house is a great consumption of thermal energy, hot water system works. The greater use of heat in the house points, the more functional will be your heating. For small residential buildings to chase the high power heating appliances, hoping to install underfloor heating, it is not necessary. Otherwise, you will have to additionally resolve the excess heat flow problem.
