The Duo-Thermo

The Duo-Thermo company has had a presence in Portugal since 1998 acting as the representative and installer of a unique heating system developed and patented in Germany. The General-Manager, Mr. Paul J. Baltes, has generated great interest in this market, progressively adapting the system to the needs and tastes of its customers, a process that has greatly enhanced the overall aesthetic quality of the system and the possibility of integrating the Duo-Thermo system in virtually any style of home, office or public building. This system has existed in Germany since 1979, having been patented in the following year under the patent license number 0025959 B1 by the engineer Horst Knappe. Its widespread acceptance in northern countries has been a great success story not only because it has met the demands of individuals and populations already accustomed to high-quality thermal comfort over the centuries but also because it has surpassed classical systems in what concerns the quality of the environment produced, the level of energy consumption as well as its practical and clean nature and the fact that it requires no maintenance whatsoever. The Duo-Thermo heating system, that is, the stone that produces the heat, is already being used in a wide range of countries such as: Germany, Austria, Switzerland, France, Belgium, Holland, Denmark, Luxembourg, Norway, Sweden, Italy, Spain, Croatia, the United States, Canada, to name but a few. Twenty-five years of experience under our belts, including studies and certificates conferred by technically specialised institutions of international recognition, have bestowed upon this system an irrefutably high level of quality and safety as well as an aesthetic quality that can satisfy the tastes of each and every one of our clients. For these very reasons the Duo-Thermo system is considered to be not only the system of the present but that of the future as well.
