We use the so-called chemical water from a district heating network; will sediment for anyway?
Chemical water will be helpful against scale and rusting, but black sediment will still be forming in the system as a result of electrochemical corrosion.
Can water containing chemicals be left in the system or should it be replaced?
Bauer treatment is chemical-free. Since thermal conductivity is best for clean water, we recommend replacing the water.
Won’t old, separating sediment cause clogging, in the various regulating valves of the system, for example?
The sediment will partly dissolve and separate in very small particles and won’t cause any clogging or any other issues. In order to remove dirt circulating in closed systems, special filters are used with the Bauer device.
How often should the filter be cleaned and how complicated is it?
Everything depends on the condition and “dirtiness” of the system. The normal filling time of the first filters is 3-4 months. Cleaning a filter is a simple act and we’ll provide you with a manual and instructions.
How big are the operating costs of your device? The power consumed by smaller equipment is ab. 40 W and that consumed by bigger ones ab. 100 W; therefore, the expense is small. Also, the maintenance of the filter and the replacement of the elements thereof are a small expense, compared to the continual maintenance and repair costs of the system. When buying a filter, 6 filter elements will be enclosed.
How can you make sure that your device is really working?
We’ll perform chemical analyses of the water as required. They will be performed in independent accredited labs, to ensure the trustworthiness of the results. Water analyses performed before and after the installation of the device will be compared. The amount of sediment accrued on the filter element will show cleaning processes too. For instance, the “petering off” (drop in efficiency, uneven distribution of heat, etc) gradually taking place in the central heating system will stop and the system will be operating as designed when cleaned.
Is it really possible to stop using chemicals at the maintenance of a central heating system?
It’s often chemicals behind the high iron content of circulating water evident in chemical analysis in many cases. High iron content, however, will cause malfunctions and prevent the operation of heating equipment, increasing operating costs. As a result of Bauer water treatment, the dissolution of metals in water will be minimised and old sediment will also be removed from heat exchange surfaces, thus ensuring the full operation of the heating system. For example, sediment of 1 mm will cause in an increase in heating costs of ab. 10% on heat exchange surfaces.
But what if no problems can be seen based on water analyses?
It may be a “hidden” problem – corrosion can be taking place under a heavy layer of sediment. In the case of newer systems active corrosion hasn’t started yet, but the varied materials used in the heating system, the mutual effect thereof, lower temperatures and also smaller sizes of the pipes will render the system extremely sensible even to low sediment and iron contents. Water analyses have often been “normal”, yet the system fails to work as designed. By applying Bauer treatment, the systems are back in work again.
Where do I install the Bauer device?
The best installation location is in the return flow pipeline, in front of the heat exchanger. Yet since the system is closed, it can be installed also after the heat exchanger.
Where should I install the cleaning filter in the central heating system?
The filter should be installed parallel with the circulation pump; the flow rate through the filter is adjusted with the help of a line adjustment valve.
