When opening the tap water from the accumulator enters the network and compensates for the sharp drop in pressure. The larger tank capacity, the less often the pump. Sales can be found accumulators with capacity from eight to several hundreds and even thousands of liters. I must say that cheap vosmilitrovye tanks not adequately cope with their problems. Thus, the draw-point (kitchen faucet, shower, dishwasher, etc.) spends from six to fifteen liters per minute, so the only missing eight liters for 15-30 seconds of a particular device. Practice shows that the optimal solution for a country house is to buy 25 – or 50-liter accumulator (cost 50-100 USD). Important operating parameters of pumping stations are the compactness of the equipment and quiet of his work.
Good performance in complex series of mq (Grundfos): their overall size is just 57x22x32 cm This mini-station will fit even on the kitchen shelf. Quiet Operation depends primarily on the design of the pump (centrifugal pump is much quieter than the vortex) and the method of motor cooling (fan or air pumped liquid). Thus, the pump motor mq cooled by water, which provides a lower noise level. Nevertheless, the leaders are pumps 'glandless' (for example, a series of chie, Grundfos). Without water, appliances can overheat and fail, so safe work in such equipment used protection from 'dry run'. This option have a series jexm (Ebara), bgm (Lowara), ngc with the automation unit brio (Calpeda), station mq (Grundfos), mcx (Nocchi), Wilo-Jet fwj (WILO) and Hydrofresh (Pedrollo).
BA more advanced version – the use of external IR receiver or IR repeater (IR-sensor small signal that can be installed in another room and connect to the device in the zone). Then run, say, DVD-player or receiver can be directly in the second zone with his full-time remote control, the majority of today’s models receivers serve as the central switching unit AV-systems, there are special connectors for infrared repeaters. Also, many modern AV-equipment is the so-called trigger ports (usually with 12 V), which are designed for simultaneous operation of multiple components. For example, you can enable video in sync with the sinking of a motorized screen, and the inclusion of the second zone (kitchen) LCD TVs to quietly monitor the development of the plot, while brewed coffee … In a complex multi-systems that have one or two controllers, control is exercised by means of desktop or embedded in the wall panels control – keypads or touch with a color LCD screen. Keypads are practical, but this is the last century. Touch panels offer significantly more features, and produces a limited number of companies.
And besides order for this placement, we reduce you to a night club, the most fashionable in Moscow, recently discovered, and you'll be with them on exclusive rights to work as a taxi and be in the cheese and butter and caviar lunch ride … "Well, we think, lucky, lucky so.

It turned out that the car as a taxi they need not even Mercedes and Jaguars, Porsches … Well yes, we said to them, and that may be all the same as a Mercedes and as a suitable taxi, S220 and S221. And then, What do you know, they give the Jaguars … We met at the club after this fashion. Arrived.
Steel entrance door. The design of steel doors is very simple – a metal frame, sheet steel on the outside door, two ribs in the cavity of the door hinges, blockers, two locks. Depending on the manufacturer, the price of steel doors are very different, ranging from 100 to 800 dollars per square meter. The question arises why such a big run-up prices? Price steel doors is derived from parameters such as – the quality of the bearing structure, the finishing material, a manufacturer of door hardware and locking systems design. Some steel doors are equipped with a rough frame of welded metal pins that are hammered into the wall first. But most of the iron doors are mounted in the door without the use of welding on a steel pin or anchor bolt.
Gas stations – it's environmentally friendly, reliable and modern units for stand-alone and backup power supply. They allow the owner to be independent from routine and emergency outages, and sometimes so that altogether cancel the service suppliers. Compared with diesel or gasoline power generators, gas have a number of tangible benefits. Petrol and diesel engines are limited to types used in these fuels. Gas power plants work well as a liquefied gas "LPG" or gas 'methane' from the main pipeline and passing gas released during oil production, which usually burned. If the electricity needs are great, compact generators easily merge, forming one strong unit increased reliability. After the failure of the stop or to prevent one of the components generator is only slightly reduces the overall power output.
