Features underfloor heating systems using metal heat distribution plates

low-temperature heating system "warm floor" in recent years is very popular among the owners of country houses. can be written radiant comfortable warmth The advantages of this system, which favorably perceived by the person, reduced coolant temperature, thus reducing heating costs as well as increased heat storage ability. But with all the advantages of the system is not without its drawbacks, which can be minimized by using a device for floor heating metal heat distribution plate.

In this article, we are using specialist Company "trimethyl" Answers to the following questions:

• What is the system of floor heating.
• What are the features of a warm floor with metal heat distribution plate.
• How to make a radiant floor heating with termoplastinami in a house with wooden ceiling.
• How to improve the efficiency of heat distribution in concrete floors with metal termoplastin.

Features floor heating system

To understand how the metal heat distribution plate improves the efficiency of warm sex, you need to understand some of the features of the classical system of low-temperature water heating.

Warm floor consists of a network of heating pipes laid on the insulation layer, which circulates coolant, e.g., water, and a rendered monolithic concrete floor.

Unlike the radiator heating, floor heating heat carrier is not necessary to heat to high temperatures. The system is calculated so as not to exceed 28-29 ° C in a dwelling surface temperature floor heating. This person subjectively perceives the radiant heat coming from the floor heating is more comfortable. As a result, the room temperature can be lowered and does not make it 20 and 18 ° C, a temperature decrease of only 1 ° C allows to reduce the annual average energy consumption of about 6-12%.

Those. the consumer gets a double benefit - and at the same time cost-effective heating system. Not surprisingly, the number of people increases every year, wishing to mount in a country house warm floor. But, with all the advantages of the system, it has a number of disadvantages associated primarily with the design characteristics and installation.

We have already mentioned that the pipes are insulated floor screed concrete, which has a large mass.

As a result, the owners of houses with wooden beams, here otnesom karkasniki, home of SIP panels, log houses (not considered UWB slab foundation and floors on the ground), are forced to give up the floor heating, because the weight just will not stand girders overlap.

suburban residents can be attributed to this group, which would like to reconstruct, without global rework, the old houses, which overlap and are not designed for the increased load from the concrete ties. The third group otnesom owners of cottages, are planning to mount a concrete floor heating, but would like to improve its performance and comfort level.

It should be noted that the classical scheme of floor heating installation is connected with the "wet work". This also imposes some restrictions, for example, if the winter concreting will produce at low temperatures. In addition, the Gulf of concrete floor, you need to give it time to set the necessary strength. This increases the timing of construction and finishing works and, consequently, leads to increase in the estimate.

I'm going to make a warm floor in a new building. Zamonolichivat pipes in the concrete floor do not want to. Thinking about how to make a warm floor, which quickly enters the working mode according to the principle came home from work, turned on, and it quickly warmed up.

Solve all these problems can be mounted if the floor heating on the base metal termoplastin, making the so-called light "dry" heat-insulated floors, or zamonolitit heat distribution plate in concrete tie.

Termoplastiny for floor heating: characteristics and purpose

Sanekxxx (User FORUMHOUSE):

I have built a house of SIP panels. I want to make the water warm floor. I am afraid that the overlap will not sustain the load from the concrete screed. I am thinking about other options. Heard about a lightweight, so-called plank floor heating system using metal plates, and wanted to know what it is, and what kind of "pie" in this design?

Dmitry Yukhimenko (Technical Specialist trimethyl companies):

Termoplastina made of galvanized steel and is a single-piece article with special "Wings" - edges of rigidity and the trough in the middle, which keeps the water floor heating pipe. Form trench made in such a way that it tightly embraces the pipe, and the "wings" on heating plate increase heat transfer area. As a result, heat is distributed uniformly, and thus increases the efficiency of the entire system.

Wafer size:

• length - 1 m;
• Width - 11 or 13 cm;
• diameter pipe used floor heating - 1.6 cm;
• weight - 500 grams.

The plates can be laid on a layer of insulation - polystyrene (density at least 30 kg per 1 cc. m), Epps or mounted on a wooden base, with without a "wet work".

Additionally, plates may be used in classic floor heating device, zamonolitiv them in the concrete floor. To begin to tell about the nuances and benefits of the so-called "Dry" installation.

Radiant floor heating on the basis of termoplastin in a house with hardwood floor

ViktorLaPipa (User FORUMHOUSE):

My house was built somewhere in the 60s of the last century. I want to make a warm floor on the second floor, but because old building, concrete screed should not be done, the overlap will not survive. I think to make the so-called "Dry" floor heating, only a "pie" will be the best?

In this situation, you can mount a "dry" floor heating with termoplastinami in two ways: to lay them on polystyrene or on a wooden base. "Cake" in this case is as follows:

• subfloor;
• insulation layer about 3 cm (or PPP Epps) or bearing pieces of wood;
• heat distribution metal plate;
• GOLS sheet 10 mm can be laid in two layers;
• substrate;
• Finish flooring (laminate flooring, ceramic tiles).

For efficient operation of floor heating systems based on termoplastin not require concrete screed, respectively - several times reduced weight of the assembly.

In fact, under such a system, when determining the load acting on the floor, a lot of floor heating, mounted "dry" method, using metal termoplastin can not take payment. Therefore, it can be successfully used in wood construction and for renovation of old houses.

The metal being an excellent conductor of heat, effectively redistribute it to the floor. Thus, although such a system and has a low heat storage capacity - an important advantage of the classic underfloor heating with solid concrete screed, it becomes a plus, as a quick access to the operating mode operation. This is especially important if the house used in the "cottage" for visits on weekends, and you need to quickly heat the room to a comfortable temperature.

the height of the heating base is also reduced.

For example, the total height of the EPS system is only 5 cm. All work carried out in the shortest possible time, because eliminates the need for concreting, reinforcement, dirty, complicated and "wet" processes.

Dmitry Yukhimenko:

Before mount a water based floor heating heat distribution plates must determine the method of laying the pipes. The simplest and most economical option - stacking "snake", but in this design due to the gradual cooling of the water can heat drops on the floor. Therefore, this stacking is used only in small spaces.

Step pipe laying and termoplastin depends on what the foundation under them is selected (foam board or wood), and how tightly scheduled positioning galvanized plate with each other.

Recommended floor heating pipes laid in increments of no more than 15 cm, maintaining the gap between the plates 10 - 20 mm.

Slots for termoplastiny in thermal insulation polystyrene plates can be cut termorezakom. For additional waterproofing system can use density polyethylene film 200 microns, mounting the rolls with overlaps of at least 10 cm and further their cementing tape. The first film layer is rolled out on the floor, which has been previously cleared of debris, and the second layer is spread over the wafers, prior to sheet GOLS. On the perimeter to prevent deformation of the structure under thermal expansion floor heating tape mounted damper.

Improving the efficiency of heat distribution in concrete floors using termoplastin

The increase in heat transfer area, through the installation of a concrete termoplastin in a warm floor, also increases its efficiency, comfort of use and will help to minimize the so-called the effect "zebras".

Dmitry Yukhimenko:

The smaller the temperature difference (heat unevenness) on the surface of the floor heating from warm to cold portion, the more pleasant to walk on it, and the more effectively it works. For example, if, standing foot to cover, you feel that the heel heat, and cool fingers, then, using metal plates, the heat is distributed more evenly, and we get rid of the "zebra".

In addition, when the metal monolithing termoplastin in a concrete screed floor heating system works more balanced. Respectively: You can reduce the temperature of the coolant, which reduces energy costs.

On FORUMHOUSE have a photo report, which tells about particular installation floor heating using metal plates and aluminum foil.
