Therefore, in such systems can be used safely only heavy and unsightly cast iron radiators, which are particularly resistant to extremes of temperature and oxygen. On a modern and efficient heating devices have to forget. The most common are systems with a circulating pump can use a pipe with a smaller cross section, and therefore, ultimately prove to be more "economical". In addition, as a rule, they closed, that is, they use the diaphragm expansion tanks in which the coolant is not contact with atmospheric air. This allows the diversity of modern space heaters – bimetal and aluminum radiators, steel panel and tubular heaters, finally, design radiators. However, and here the problem of dissolved oxygen and corrosion does not cease to be relevant.
If, on domestic regulations, the oxygen content in the coolant should be no more than 0,02 g / l, in practice and in the central systems, and autonomous (with intensive feeding of) this value is ten to twenty times more. It is therefore reasonable to use modern, corrosion-resistant pipes, for example, such as tubular steel radiator Charleston Pro (Development Zehnder) with a special internal anti-corrosion coating. "Pitfalls" Mounting As previously mentioned, assembly defects are manifested at once. Often "in place" they are difficult to observe even for an expert. Shortcomings declare themselves in the worst possible moment – during the heating season. They appear usually leak coolant and reducing power of the system, because of what housing does not get the right amount of heat. Major errors installers, for which then pays the customer, are fairly typical.
And the third area of work that I want to designate – is raising the prestige and the overall level of professionalism Realtors. Today, unfortunately, often do not pass the deal through, but in spite of the professional level of the agent. I would like to see employees of all self-respecting company is constantly mindful of the fact that they act primarily all in the interest of the client, think about maintaining the prestige of the profession and that successfully carried out, quality deal for them would be the best recommendation. I do not welcome the holding of deals just to generate income. Income – It is a consequence, the reward for a job well done by the deal, but first you need to think about helping people. But this does not exclude the possibility that the realtor must know the value of their work and be able to properly explain the cost services. I spend training for agents and teach them to respect themselves and their profession to be able to explain its importance to consumers, because many seem to understand the value of their work, but when dealing with a client and can not tushuyutsya explain what they are doing, why you need to contact the company and not to the particular agent, why not work with multiple companies simultaneously.
