The Elysator Family

In the past, the majority of underfloor heating were installed with plastic tubes, which are not impermeable to oxygen. Meanwhile, it is fortunately easily possible to produce heating pipes for floor heating systems and to obstruct the diffusion function on nearly tight. Indeed, the best heating system also disposes of enough elements, which cannot call this quality their own. This is valid not only for valves, screw connections, circulating pumps, but also for control units, automatic breathers and defective expansion vessels. At these places, it also comes in very modern heating systems to an unintentional oxygen admission. This oxygen, a too deep pH factor, but also a raised conductivity of the filling water are typical triggers for damages of heating installations.

To guarantee a long life span for modern heating systems, all manufacturers give comprehensive tips and directives. These suggest demineralizing the filling water for every heating system. A reason for it are experiences from the practice, which underpin that already minimum steps of hardness in the filling water lead to damages in high-quality devices like gas-fired hot-water tank, warm pumps and solar arrangements. One of the most frequent causes is the amount of lime in the filling water. Using the example of a detached house with a heating system of 350 liters system water content results in average amount of 100g lime in the filling. Although this amount may seem small, it is able to damage by lime precipitation the built heating system permanently. The amount of lime increases, of course, with the amount of the used filling water. In addition, it varies from region to region due to the different degrees of hardness of the tap water.

Counteract corrosion from the beginning

Also damaging for sensitive devices such as heating baths is the penetration of the filling water with salts. Therefore, it comes to corrosion of the lines within the heating system. Electrochemical reactions have a harmful effect on the metallic parts of the system and accelerate the wear process. Benefiting from a high amount of salts the formation of galvanic elements is promoted that ultimately cause this corrosion. It also contained in the unfiltered water, chlorides, sulphates and nitrates have their not insignificant proportion.

It is true that, at simple softened water, calcium and magnesium ions exchanged for sodium ions, thus removed from the water hardness, and significantly lowered the hardness grades, but the salinity of the water remains unchanged. In case of modern systems, an important damage factor remains completely unchanged.

Earlier it was especially set for inhibiting corrosion on chemical types of corrosion protection. In many cases, however, it was found that especially in hard to reach places on glands, but also in already by rust and dirt damaged places no more active protective effect could be obtained and the real problems were solved so only dissatisfactory. Made even more difficult to perform such protection method proves the need for constant monitoring. This is not only time-consuming but also costly. The attempt to split the heating system into two parts (heating circuit and kettle circle) by using heating exchangers, only leads to two separate problem areas in the long run, but not to sustainable solution to the problem. In addition, modern heating systems are significantly more prone to silting, blockage of control valves and pumps and precipitation by lime and other water constituents. The consequences range from quick corrosion breakthroughs in the boiler, flow noises by gas developments, increased energy consumption to serious water damage.

The Elysator family

With over 30 years of experience and the most environmentally friendly and most sustainable operating system on the market for filter systems for heating systems Elysator provides the Elysator and Elysator trio not only for operators of large heating systems, but also for wise individuals with economy activity the optimal solution. Both systems are designed for the most different large heating systems and can be easily integrated into existing systems. Both the Elysator and the Elysator trio are extremely low maintenance and do not require am external power supply. In the normal case you will need service every three to six years with the Elysator whereas you needed a service once a year where you had to spend lot of money and time without the Elysator.

Both series come completely without the use of chemicals and are recommended by leading professional associations, institutions and producers.
