Types of underfloor heating
Underfloor heating is available in many variants. Indeed, it is increasingly replacing the traditional central heating system, which uses radiators. There are three types of underfloor heating, such as:
- air - it is relatively little known, which does not change the fact that it is
functional. It is a really good alternative to traditional radiators. It consists of combining a foundation structure with air floor heating. In this case, the air channels create a closed circuit. However, you need to be aware that such floor heating cannot be installed in a finished space. It is best to plan it at the stage of building the house. - electric - this is a solution that does not generate high operating costs. This is a particularly good choice if you want to supplement your current heating system. It works best for individual rooms. In this case, heating cables are installed under the floor, but it must be remembered that they must be made of materials with appropriate electrical resistance. The materials heat up and release heat into the environment. Of course, the temperature can be regulated. A thermostat is used in this case. This is a relatively cheap solution, and at the same time convenient to use.
- water - enjoys the greatest popularity. This type of floor heating ensures even heat distribution, as well as high comfort of everyday use. You also don't have to worry about air circulation. The system is based on heating pipes through which water flows. Of course, you still need to install additional devices. We are talking about valves or a boiler, and the operating costs are really low.
Costs of installing underfloor heating in the Onnline system
Installing underfloor heating is a good investment. We can say that it will pay off really quickly. Here we can recommend installing underfloor heating in the Online system. All materials meet the most stringent quality standards. Of course, the price of the entire heating is influenced by the size of the surface. You should choose the right pipes for underfloor heating. The recommended pipe diameter depends on the length of the loop. Onnline offers pipes with a width of 22 to 36 mm. You should know that if you use too small a diameter, the flow resistance will be too high and the circulation pump may have a problem overcoming it. The costs of installing underfloor heating include all the necessary materials, as well as the price per square meter of the specialist's work.
The price of the contractor's work ranges from PLN 20 to PLN 100 per square meter and depends on the experience, reputation of the company, and the degree of complexity of the underfloor heating installation. It is important to realize that labor costs are higher in larger cities. In addition, a square meter of water heating is cheaper than a square meter of electric underfloor heating. The price of various types of tools in heating systems must also be added to the installation costs. One of them is a return temperature limiter, which prevents overheating of the installation and at the same time saves energy.
Necessary materials for Onnline brand underfloor heating
It is worth investing in the necessary materials for underfloor heating that ensure efficient operation. These include:
- underfloor heating pipes - here
you should pay attention to the material, which should be strong and resistant to corrosion. A corrugated casing pipe, also known as a conduit, works very well. It provides protection for the cables against mechanical damage. It is also extremely resistant to stretching and compression, and thanks to its intense color, it allows for even easier identification of the cables. You can choose blue or red casing pipes. - hooks and clips for underfloor heating - small accessories for underfloor heating are also important, including hooks and clips. You can choose those for manual fastening on polystyrene mats. You can also choose clips for rails. They can be used to easily fasten underfloor heating pipes to the insulation layer. Hooks also play an important role. They are used to fasten double pipes. They should be selected according to the drill bits.
- underfloor heating distributor - this is an important element of the entire installation. You can choose a model with an electronic pump or a distributor without accessories. Various numbers of circuits are available. The underfloor heating distributor plays a very important role, as it transfers the heating agent to the entire heating system. Thanks to it, all circuits have the same flow rate.
- cabinet for the distributor - protects the distributor from mechanical damage. It should therefore be durable, impact-resistant and easy to install. Here, you can choose a flush-mounted cabinet, which is used to mount the distributor with a mixing system, but also without such a system.
- floor accessories - these are other essential elements of the entire installation. These include, for example, a central strip. For example, you can decide on a wireless one. You need to pay attention to the number of zones. An important element is the temperature regulator. For greater comfort, but also safety of work, a pipe unwinder should be used.
How much does a square meter of flooring cost - estimated cost
Underfloor heating is not very expensive. The cost consists of materials. This is an expense from PLN 80 to PLN 180 per m2. This applies to water heating. The price of materials in the case of electric heating is higher and ranges from PLN 90 to PLN 300 per m2. In addition, there is also the price of labor. However, the costs should not be reduced by choosing cheap materials. It is worth choosing systems from renowned manufacturers such as Onnline.
