New types of heating apartments and private houses give the developer a real opportunity to establish an alternative source. The system of heating the water floor allows you to create and combine heating with water heating. But this is not the limit, ahead of the unusual yet plinth and wall heating options. The main thing is to correctly calculate the parameters of the system, purchase the necessary materials and perform the installation of the system.

Warm floor for heating the house
The system of the warm floor is of great interest today, it is in demand and is available for self-assembly. Traditionally, the heated floor in a city apartment is used as additional heating.
Owners of private houses are lucky, they have the opportunity to install any system of water-heated floor before the onset of cold weather, thus solving the issue of heating. The floor heating of a private house can be considered a low-temperature CO system, in which the temperature of the coolant does not exceed 50 ° C.
The heated floor in the private house is exaggerated like a convector, in which the heated water passes through pipes arranged under the screed under the aggregate of the distribution manifold.
The design of the water-floor heating system must begin with a heat engineering calculation in the mode on line calculator.
Thermotechnical calculation
The purpose of heat engineering calculation using the "coefficient method" is to obtain the values of the parameters of the warm floor:
• specific heat output
• average floor heating temperature
• Specific flow rate of the heat carrier.
In the program calculation algorithm, averaged coefficients are introduced that take into account the effect of the pitch and diameter of the pipes, the material and thickness of the finish coat, and the thickness of the screed.
The results of the heat engineering calculation are: a sheet of material specifications in tabular form and a schematic image of the assembly unit. In accordance with the calculation results for the system parameters (nodes and collector), you can purchase materials according to specification.
Schemes, materials and types of underfloor heating in the house
The choice of schemes of a warm floor in the house is justified by concrete factors and efficiency of operation. There are some installation and installation methods that determine the types of water-heated floor and installation rules:
• flooring
• in a concrete screed.
The only thing that unites installation of kinds of a warm floor, these are rules of placing of pipes, excluding a lining of a highway concerning the established furniture.
Let's say that the installation of a heated water floor is effective when observing the temperature regime, namely the floor surface temperature is not higher than 28-30 degrees.
water heating technology
The technology of the device of the water-heated floor, installation rules and recommendations are based on the creation of a multi-layer cushion:
• soil or slabs with a sandy pile of rubble of a fraction of 0.3-0.5 cm, a polyethylene film on which a black crushed stone screed of the fraction 0.05-0.1 cm is placed, the total thickness of the layer reaches 7-10 cm
• waterproofing and thermal insulation layer, the thickness of which is determined by calculation
• Coiled waterproofing layer, reinforced with aluminum surface
• metal-plastic pipes with internal ø 16 stacked according to the chosen method
• concrete screed, reinforced with a 10x10 grid of 0.4 cm wire placed above the pipes
• Finish the floor.
The technology of the handheld device of the warm floor is backed by useful advice and installation rules for the main types of water floor.
rules for installing a flooring water floor
The floor installation of a water-heated floor consists of the following stages:
• installation of a mounted collector point on the wall
• laying of the insulation of the rough floor from polystyrene mats with technological grooves for pipes, mineral wool under the wooden basis (lags, modules and plates of particle board)
• waterproofing with reinforced material
• laying pipes according to the selected scheme with subsequent connection
• laying of the substrate for the finish finish (expanded polyethylene, gypsum fiber boards, acting as an element of the screed)
• flooring of the finish coat.
rules for installing the heating of the water floor in the screed
Installation of the water floor in the screed involves the following steps:
• installation and installation on the wall of a collector station with a pump-mixing unit and a collector block
• Damper banding around the perimeter of the floor
• flooring of waterproofing material
• laying of reflective thermal insulation material
• placement of reinforcing mesh or polystyrene mats with grooves and bosses for heated water pipes
• connection of pipe ends - one to the collector outlet for feed and the other end to the return
• connection of the thermostat via a communicator with a servo drive
• crimping of pipes in operating mode and checking for leaks
• Preparation of a mortar of a concrete screed from a dry concrete mix on cement base M300, which includes plasticizers and polypropylene fiber (the thickness of the screed is up to 5 cm)
• complete drying of the screed and subsequent covering of the finish coat.
How to install a self-installing underfloor heating system, starting from the rough floor, is presented in the video.
equipment for water floor
The device of a water heated floor in a private house is a labor-intensive and expensive exercise in which it is necessary to use such equipment:
• boiler
• Collector
• Mixing unit
• circulation pump
• pipes at a rate of 5 m per 1 sq. M of heating area.
When installing and installing the water floor, the area using inter-planar damper profiles is divided into sections. The breakdown is made at the beginning of the installation of the pipes, combining the sections with the contours. In practice for the device of a water floor I use pipes with internal dia. 16 mm, considering the length of the one-piece pipe not more than 90 m, which ensures the circulation of heated water of the set temperature.
How to install a water-floor pipe, shown in the video.
After installation of pipes and equipment, the parameters of the warm water floor system are set and the system starts up.
In addition to the water heating of the floor, there are several options for an electric warm floor, the installation features of which depend on the finish coating material, presented here, However, the advisability of a water floor in a private house is more appropriate.
Thus, it can be concluded that the water heating of the floor of the house has the prospect of using technology to heat the walls.
