Correctly designed electric floor heating is, undeniably, one of the most luxurious and effective ways of heating. It has been used in Scandinavia on a wide scale since the 1990s, particularly with the arrival of what are known as laminate and wooden floating floors. A sign of customer satisfaction is not only the ever-growing number of such products sold, but also the relatively high speed with which they are spreading to more and more new markets.
With the growing popularity of heating foils, new producers and distributors have also appeared, mainly from Asian countries. They are trying to sell similar products, often without sufficient knowledge of how to produce or install them. > > >
It’ll help you understand how to determine the required output for heating, what heat loss is, why it is sometimes more advantageous to choose large-scale surface heating and sometimes direct heating convectors, if floor heating can really heat the whole house and why electric heating is the most suitable heating system for low-energy houses (LEH). > > >
In the third part of the series about the construction of an energy-saving house in Moravany u Brna, practical experience with the heating system and the real operating costs in the previous calendar year are described, and also the quality and method of heating is detailed from the point of view of the location of the source. A comparison of the distribution of air temperatures in the vertical plane in a room with floor and ceiling heating was carried out. > > >
The calculations in the first part of the series of articles about the construction of an energy-saving house in Moravany u Brna confirmed that this design with its electric heating system will be very economical; the project author also appreciated the variability of the heating system, the accuracy of regulation and the high user comfort. Thermal comfort throughout the house will thus be provided by FENIX Jeseník products - for the REP-HOUSE, floor heating via ECOFILM foils was chosen for most areas, and ECOFLOOR heating mats were fitted under the floor tiling in the bathrooms and kitchen. In two rooms, the author designed ceiling heating using ECOFILM C foils. Of course, this is all with BMR central regulation. > > >
The aim of the REP-HOUSE design project, an energy-saving house in Moravany u Brna, which was created through the cooperation of the author of the project with Fenix Jeseník (the largest domestic producer of electric heating systems and one of the REP-HOUSE project partners) is to demonstrate the capabilities of the contemporary building industry in the field of low-energy and passive structures. The author of the project is an associate professor at the Faculty of Civil Engineering of Brno University of Technology. As early as during his doctoral studies, he was engaged in research in the area of energy saving in structures and the possibilities of increasing the thermal resistance of masonry blocks. He lectures on the topics of the thermal protection of buildings and low-energy structures at the Faculty of Civil Engineering of BUT and thus it is logical that his own family home could function as a small ‘laboratory’ where he can try things out for himself from the position of a common investor – i.e. starting from the design stage and moving through the execution of the building up to its eventual utilization, including all the consequences of his decisions. From the beginning, it was therefore his main aim as the author of the project to design a house with internal thermal comfort both in the winter and summer seasons and simultaneously with an emphasis not only on the acquisition costs but mainly on the lowest possible operating costs. > > >
Ortotech s.r.o. provides comprehensive services in the area of orthopaedics, prosthetics, physiotherapy and production of tailor-made orthopaedic and prosthetic medical devices. While carrying out the renovation, the owners of the company decided to use electric heating to upgrade the heating equipment and especially to be able to employ their own production technology. > > >
Matyas House was built within the precincts of the Town Castle around 1479 and it was incorporated in the Miners' Bastion. The house is a tall four-storey building adjoining the Slovak Church. The majority of rooms are with flat ceilings, only some of them on the ground and first floors are barrel vaulted. > > >
Medial virtual reality keeps confirming the conviction that the growth of energy prices applies exclusively to the electric energy and the rise in the prices of gas remains almost without any comments.
What is the reality, though – let´s look at some hard data published by EUROSTAT:

The Golden Lane at the Prague Castle was festively opened after a year-long reconstruction on 1st June 2011. The main objective of the reconstruction commenced in May 2010 was to repair the obsolete rain water drainage system. The situation was serious as the status of the system was endangering the structural stability of the individual buildings.
During the renovation, a complete reconstruction of all underground services and internal wiring inside the total of 16 period houses was carried out. The whole renovation cost approximately CZK 34 mil, additional CZK 5 mil were invested in restoration works.
In April 2010 the Fenix Group produced a report titled "ECOFILM Ceiling Heating in Low Energy Houses". The purpose of this report was to demonstrate that satisfactory thermal gradient comfort curves can be achieved for large area low power radiant ceiling heating systems installed in low heat loss properties. > > >
A video appeared on a publicly accessible web page
where the panel ECOSUN 300U is compared with a product of the Chinese company YUNSOR.
It is clear from the course of the test and its conclusions that the manufacturer does not have sufficient knowledge in the field of thermodynamics and his conclusions are entirely misleading: > > >
In July 2010 our Turkish partner, the company YS Mimarlik, installed heating for the playing field at the Kasimpasa premier league football club’s stadium in Istanbul. The new grass surface with electric heating is part of a complete reconstruction of this stadium. ECOFLOOR MAPSV type heating cables with a wattage of 15W/m were used. > > >
Anyone considering the construction of a house today almost certainly assumes it will have a minimum of class B energy efficiency, or possibly be on the border between A and B, or even be wholly within the A band (more about PENB – the energy performance certificate for buildings – can be found here…). In other words, it will be at least a low energy house (LEH), or almost a passive house. It is probable that no one today is planning buildings with worse heating characteristics. One of the choices which have to be made concerns the selection of an appropriate heating system. Much has been written about this issue, and much of that contains varying and sometimes even mutually contradictory recommendations. The reason for this is not only that the writers have different subjective viewpoints, but also different priorities which bias their arguments.
In the winter period, harsh climatic conditions can lead to complications on construction sites during repairs to damaged gas and water networks, excavation work etc. Such problems can be avoided with the help of FENIX electric heating systems. > > >
The virtual reality created by the media gives the impression that the growth in electricity prices is way out of control, and that it is significantly higher than the growth in prices of other energy sources. But what is the situation really like in the EU and in the Czech Republic? Let’s take a look at the hard data published by the EUROSTAT agency: > > >
