The "Stalinist" houses and the old foundation walls of the inner often a plank wall. In modern building interior walls made of gypsum concrete generally, foam, etc. giprokartona Partitions of the above materials have very little bearing capacity and durability. It is recommended before final selection of "To tap" the wall. If the wall is concrete or brick, even if it is thin (for it is ventshahta) can safely hang up on her water heater to 100 liters in volume. Water heaters up to 200 liters are advised to hang up only on the load-bearing walls. If the walls have a low carrying capacity, then we recommend installing heaters on them no more than 50 liters, or make them a special metal frame.
I would like to add that most amount purchased – it is 50 liters. 2. Selection: Choosing a stainless steel or enamel water heater, you will inevitably face a dilemma: water heater tank with an internal stainless steel or enameled with a tank. Enamelled tanks are cheaper, but the Russian people by ear certainly nicer word "stainless steel". "Corrosion" in our mind represents something sturdy, perpetual, well made. Conventional wisdom is that "stainless steel" is expensive enameled tank at 30 – 100%, but is several times longer, and with it you get trouble with frequent replacement of the magnesium anode, in other words in the Russian context, where the low quality of cold water, the optimum use water heaters, stainless steel. 3. Size, shape currently range of water heaters is very wide.
Another important question, which depends on the design drawing – is its location: in the corner against the wall or on the "island." In Depending on this, and the type of drawing is angular, island or wall. EXACT SIZE One of the main parameters that must be considered when selecting exhaust is its width. Hoods should not be already cooking surface, otherwise not all the evaporation from the surface will fall into the hood, some will continue to spread through the rooms. Too broad range hood, much bigger area of cooking surface, also useless. No, of course, pulling the air, it will be better, but the noise – is stronger. NOISE But the next most important parameter – this is noise. This parameter by itself can do little to characterize the hood, it is always necessary to bring (and perceive) only in conjunction with the corresponding value of the noise performance. If you want to determine which model is less noisy, you should compare the values of sound pressure at equal performance.
There is another approach. You can compare which of the extracts will be more productive at the same level of noise. For information: whisper creates noise 25 … 30 dB, the compressor refrigerator – 38 … 43 dB, the conversation – 50 … 60 dB, the allowable for a permanent job is considered noise v70dB. Productivity No matter how important the appearance of drawing, and whatever requirements are imposed on it "noise" performance is one of the main parameters which determine how well and how quickly air can be cleaned in the kitchen.
The word 'verification' in our world it's not so long ago. Most people hear 'verification' in a hurry to fix – 'check'. And wrong – just checking. Without the letter 'P'! However, these words are not only consonant with, but close to nature. Verification – the same check, but + devices! Testing, which from time to time subject to the instrument, so that was confirmed by their suitability for further use for other purposes. It is understandable, because, sooner or later, any device wears out and starts to cheat. How we test clock for precise time signals, and test instrumentation (and well: confide!) For the most accurate – the standards! Therefore, calibration is konkterny view Test instrumentation for their professional competence.
Verification – this is a very serious matter. Because the organizer span affairs in Russia today metrological principles was himself Dmitri Ivanovich Mendeleev. With the direct participation of the great scientist in 1900 was created the First Moscow tent verification of weights and measures. Today it is a Federal State 'Rostest-Moscow'. Russia's largest institution of practical metrology. Segogodnya annually more than 2.5 million measuring instruments are checked against etalolnami that are in Rostest-Moscow. But widely in the home with the notion of verification, we have encountered just recently.
Literally a year or two ago, meter verification was concern for energy suppliers. At that time the price 'for the light', 'the gas' very few cared what exactly is considered the counters. And we trust takes readings, especially without thinking whether they can trust, and how, who and how often should verify their authenticity. Now the situation has changed.
