This new technology of efficient, reliable, durable and affordable communication systems in Moscow. Scope of PEX fittings and other items produced by this technology – a system of cold, hot water,PEX radiant heating.

When installing pipes made of polyethylene, polypropylene, is normally used diffusion welding performed using simple and inexpensive equipment. This connection method does not require special skills and available to everyone. The design of the result is a completely sealed, and the welding process takes very little time. Thus, the connection is ready for operation immediately after cooling (2-3 min.). PVC fittings are generally used for sinks without pressure, so they are not welded together, and fastened with bells, rubber seals, less often – glue joints.

Use of PEX pipe fittings usually provides a significant economic effect: the cost of transportation and installation are reduced in comparison with steel pipes in a few times. The economic effect of the use of pipes and fittings, as compared with steel and cast iron is made up of savings on freight costs, reduced labor costs and waste during installation, cost of supplies, lack of expenditure in the period of operation, as well as a significant life – about 50 years. If all these data into account when determining the value of the pipeline and the estimates, the assembly made of pipes and fittings will provide cheaper by 15-20% compared with the pipeline, made of galvanized steel pipes.

PEX Pipe made of polymers have a number of advantages over steel: the weight of a small PEX tube, they are stainless steel, seamless, not overgrown during the operation, do not vibrate and emit a humming sound, do not break when water freezes (System can withstand multiple cycles of freezing in the presence of pressure without destruction), do not make stray currents do not require painting and are easy to install. For example, pipes and fittings, depending on the operating pressure can work for decades with the temperature of the liquid to 95 ° C. Polypropylene and polyethylene pipes are environmentally friendly and are successfully used in pipes of cold and hot water, heating and air ducts with a working pressure of 25 atm.

Due to the fittings with chrome-plated PEX brass pipe fittings easily combined with steel pipes and steel bars, while laying in the ground do not require additional insulation. In addition, in recent years actively introduced

You need Tankless Water Heater Valve Kit and mostly recommend Radiant Heat Manifolds for install also you need PEX Tool

If you believe that the Tankless water heater room – troublesome and expensive, and hot water is still needed, then your home water heater is ideal for summer residents and urban residents in three scorching summer months – it is generally ideal. Especially since most of the water heater works on gas or electricity. And if your house with no electricity, the gas cylinder will be required.

There are two types of water heaters – instantaneous and cumulative. In the instantaneous water heaters water is heated to the desired temperature, passing through the heater (radiant heating coil) and derives from the device is already hot. Instantaneous water heater has no tank, where water could heat up. Therefore, to heat the large volume of water requires large amounts of electricity. For taking a shower requires unit capacity not less than 8 kW. Our Canadian standard wiring is designed for much lower power. Moreover, because of poor water quality on the radiant heating coil quickly formed lime, which reduces the life of the heater. To install instantaneous water heaters you will need more and additional equipment like automatic-protection and a separate cable to connect. All this greatly increases the cost of the heater.

Regardless of the method of radiant heating water heaters are divided into instantaneous and cumulative. Electric water heater compact and give hot water immediately. Despite the large electric power, these devices are quite economical, since the power consumption only during the percolation of water through them. There are flow heaters of various capacities. For example, a whole range Stiebel Eltron Tempra (Germany) includes a miniature device to one source (17 l / min), and devices that can provide hot water cottage (up to 22 l / min). They consume power from 12 to 36 kW. Expensive models are equipped with microprocessors that support user-specified temperature. Typically, home wiring is not designed to connect high-power device, and setting “Stiebel Eltron Tempra” may require a separate power supply circuits with its own circuit breaker, wiring and grounding of the section. Typically, instantaneous water heaters with capacity exceeding 15 kW p for three-phase power.

Panel heat transfer plates of aluminum produced in Canada with 50-ies. and well-known domestic consumers. radiant heating panels – is two welded together forged, 1/2 PEX Crimp tool, forming a series of vertical parallel channels, which are combined with horizontal collectors. The panels are made in single and two-row version without convection fins, as well as fins and decorative coating of heat-resistant enamels. aluminum is more than cast iron or aluminum, corrosion and therefore this type of heaters are more suitable for closed radiant heating systems – in cottages, low-rise buildings, and if an individual item of the heat – in buildings of any height. aluminum heat transfer plates in the majority of an operating pressure of 6 to 10 atmospheres, hydrostatic testing – 13 atm and the maximum coolant temperature of 1100 C to 1500 C.

Along with aluminum, manufactured in Europe bimetallic panel heat transfer plates, which are aluminum tubes that are filled in monolithic panels made of aluminum with fins or without him. Bimetal heat transfer plates free from the shortcomings inherent in an aluminum heat transfer plate (susceptibility to electrochemical corrosion, the possibility of hydrogen generation due to chemical reactions, which enters aluminum), but have the same thermal efficiency. They are used in all radiant heating systems, including those with high blood pressure. Pressure bimetallic heat transfer plates – 25 atm hydrostatic testing – 37 atm, the maximum coolant temperature – 1100 S.

An alternative to cast iron in an aluminum radiant heating engineer, from which the more striking in appearance and less metal-consuming heat transfer plates. The advantage of aluminum heat transfer plates is that they heat the room faster than cast iron heat transfer plates, and well-controlled byLUX  thermostats valves. They are pressed, manufactured by injection molding or extrusion molding section and collectors that are interconnected with special pipe nipple and tightening bolts. Metal consumption of such heat transfer plates – in the range of 11 to 21 kg per 1 kW of heat, it depends on the distance between the collectors and design sections. Aluminium sectional heat transfer plates of different construction and an operating pressure of 6 to 25 atmospheres, hydrostatic testing pressure from 9 to 37 atm, the maximum coolant temperature to 1300 C. Aluminum heat transfer plates are good in the radiant heating systems, which kept the acidity of the coolant (pH of water – within 7 – and measures to prevent sudden changes in pressure and temperature. To prevent electrochemical corrosion in the joints of aluminum sections with aluminum pipes must use pex crimp tool.

In the heating expansion of the liquid, and hence the loading of the expansion tank is slow, and during the entire period of the system varies slightly. However, the operating temperature can reach +90 ° C. Therefore, the main criterion for selecting the material for expansion tank expansion tank heating system is resistant to temperature and longevity.

Many of our compatriots are perplexed by the problem that it is better to buy, reliable electric tankless water heaters Proterm, for example, or that the manufacturer), or indirect heating tankless water heater. It may be noted that the tankless water heater, as already noted, quickly produces hot water, in that, in principle, and is its only advantage over electric tankless water heaters.

Continuing the theme of the classification of gas-fired tankless water heaters, you can also divide the devices into several types depending on the method of removal of gases emitted during operation of the tankless water heater (with forced or natural draft) and the type of ignition of the tankless water heater (piezo or electronic).
