Radiant Heating Design

When designing the radiator heating we calculated heat loss in areas of the building and on this basis, selected size and type of heating appliances. Next is placing heating appliances (radiators, convectors, etc.) and supply of coolant in accordance with the scheme specification. The project also includes a radiator heating design risers and mains heating system.

The scheme presented below, in fact, the “skeleton” system radiator heating. This figure shows the place of installation of heating appliances, as well as the coolant supply lines.

We believe that with this attractive and functional interface, as well as increased opportunities of climate control, a LUX Thermostat will be a great future.

Herewith:

* Exchanger understands
• Remove all plates
* Plates are soaked in a special solution
* Each plate is washed in hand ”
* Package is inserted into the heat exchanger plates
* Exchanger is collected and is pressed.

Advantages:

Demountable flush 100% provides a guarantee of quality.
Eliminates contamination of any kind.
Everything is clear and the customer sees the whole process works.

Disadvantages:

If the heat exchanger has worked in critical conditions, or the life of rubber seals come to an end, it is likely that seals the heat exchanger will have to change (ie, cost and terms of service activities will increase)

The scheme Collapsible cleaning the heat exchanger, as a rule, differs only in the choice of a particular method of cleaning the heat exchanger plates after disassembly. Use a few basic ways:

- Collapsible for washing the heat exchanger is sometimes possible to remove contamination with a jet of water from the pressure washer.

- In case of more serious sediment in the heat exchanger, with collapsible washing the plate heat exchanger was originally purified from the upper layer of sediment with high pressure, and then soaked in acid solution, and then again cleaned with pressure washer.

* Chemical method of cleaning pipes and PEX heat exchangers from scale
* Water pumping method of cleaning pipes and heat exchangers from scale.

When descaling of pipes and heat exchangers, chemical method easiest to dissolve (rather quickly, with minimal concentrations of acid at higher pH values, with a minimum water temperature) scale, which contains calcium carbonate and magnesium hydroxide.

Somewhat less soluble scale, consisting of corrosion products. corrosion (rust) and alluvial sludge, containing oxides of iron (III and IV).

That’s why we recommend to clean the pipes and heat exchangers from scale in a timely manner, so as soon as regulyanaya descaling can guarantee the stable operation of the heating system, heat exchangers and pipelines in the winter season.

When cleaning the heat exchangers and pipes from scale worst dissolves scale, containing silicates (CuO, MgO, SiO2) and organic compounds.
The risk of late descaling.
Late descaling and scale removal can lead to various undesirable consequences:

* Burnout fuel untimely removal of scale as a result of reduced heat scale. Since the thermal conductivity of carbon steel, 46-58 W / m ° C, and boiler fouling 0,082-2,3 W / m ° C, then obviously the increase in fuel consumption, the volume of flue gases and reduce boiler efficiency when dealing with scum-like layer on the inner surfaces of boiler pipes in the absence of timely cleaning of the boiler.
* At large thickness of scale increases the resistance of the passage of water directly to water pressure, there is a violation of circulation, which leads to burnout of the metal

All these reasons – an important occasion in a timely manner to service operations to remove fouling in heat exchangers, boilers and pipes. JSC “Unified Service Center offers a range of services to ensure a stable and reliable operation of plate heat exchangers.

Qualitatively, and you need time, we carry out:

* CIP and collapsible chemical cleaning of heat exchangers
* Repair of heat exchangers
* Replace the plate package of heat exchanger
* Chemical cleaning of heat exchangers
* Increased capacity plate heat exchangers
* Replace the seal plate heat exchangers
* Delivery of spare parts for plate heat exchangers

You can also purchase equipment and reagents for cleaning heat exchangers

On the pages of our newspapers, we have already presented an affordable and efficient way to heat yourself and others through the space heating through the floor, and a specialist team of technical information IGO Electric revealed the secrets of electric cable heating systems. In principle, they can be used as basic as you can not connect to the central heating, and as additional, creating a cozy rooms, offices, bathrooms, basins, toilet suites.

- Batteries are rarely improve design and building heat unevenly, and the floors are often cold. The heating elements are “warm floors” are hidden from the eye, but allows the thermostat to control the temperature within specified limits. “Warm floor” is safe to use, reliable and durable, – said Serg, and explained the device of this system:

- It is based on the radiant heating cable or heating mat that is placed on a rough floor at the stage of renovation. Control of the heating cable is controlled by a temperature sensor and thermostat.

Heating can be direct, that is heated directly in the connection. It is used usually in wet areas. And partial-accumulation – when the floor gives off heat during heating, and after a power outage, have your own accumulated. It is used mainly in areas where coverage has a large thermal resistance (parquet, carpet, linoleum).

S. Puhtin noted that the latter type of heating is suitable for use dvuhtarifnogo electric meter: the heat stored in the watch cheap night rate, passed the room during the day.

Cable Kits “Teplolux” Made LLC Special Systems and Technologies “, Mytischi) are recommended for bedrooms, nurseries and other rooms where people spend most of their time. Products of different brands of this series can be chosen so that the warm area from corner to 1,8 m2 to room 20 m2, with consumption from 0.27 to 2 kW, as required heating section (a section of twisted pair cable of fixed length) are added. Includes a section itself, thermostat, temperature sensor, which is mounted in the floor, and bellows for him. Metal mounting strap with petals can rigidly fix the cable and even withstand a step layout for attaching the section to the floor. The system allows not only to maintain the required temperature, but also to save while a third spent on heating energy. And by using thermal insulation (for example, “Termofola – polyethylene foam with a layer of lavsan and aluminum foil) are useless and excluded the lower heating floors.

Manufactured to provide greater electrical, mechanical and fire safety and security, not recommending, at the same time, mounting system under a stationary arrangement of furniture and equipment (sofas, cabinets, dishwashers, gas stoves).

Cable «Tassu» Finnish company «Ensto», in principle, similar to domestic, differs only by specific characteristics. He is ready for laying a shielded heating element power density 20 W / m Laid at a depth of 3-8 cm below the cement flush and decorative coating. Available in nominal capacity from 0,24 to 2,2 kW and is designed for space heating from 1,5 to 27 m2.

Heating mat – will not complicate anything in the explanations – is the same heating cable, with the same electrical characteristics and heat-generating opportunities. Cable is enclosed in a two-layer insulation and braided shield. But the math simplifies installation, as producer half of your work is already done: he put a snake on a special cable net, fastened it to her and written instructions what to do next.

And then you have to prepare a place for the thermostat (it can be installed individually or in alliance with the sockets, switches), proshtrobit wall liner for food and the floor beneath the sensor, to sweep the floor, bedding insulation pack mate, ask a specialist to perform the electrical connections, put flooring (tile, carpet, flooring) to the appropriate solution, glue or paste, and, after 10 days, to begin to enjoy the comfort.

Note: after 10 days, not 28, which are necessary for drying thick cement ties at installation “vnematovogo” cable. Just in the cement covering is not necessary.

“Mat” Teplolux-mini »of Mytishchi can be installed in conjunction with other types of heating devices. The mats are placed in a solution for fixing flooring.

«ThinMat» Company «Ensto» – one of the latest innovations in the Finnish assortment MPO Wiring “. He looks like a native, but made in the company «Ensto». Again, that the mats, as well as cables can dock to warm up the largest area. And you can “cut” grid (without breaking the cable!) To lay the mat on the floor of a complex configuration or circumvent sofas and cabinets.

This is not just “warm”, ideal for direct heating, but also “thin” the floor. At its core cable is almost twice thinner than that of «Tassu». And mounted on the surface of the floor mat is easy, on the basis of self-adhesive, a layer of tile adhesive or mastic. He produced a strip of 48 cm in length from 2 to 10 hours to a single thermostat can connect two identical mat.

- Bear in mind that not every flooring material suitable for use with such heating systems, – said Sergei Puhtin. – For example, beech flooring, cork boards or planks of the floor for this little fit. A heating bath and other wet rooms should be used more and the unit breaker at 30 mA.

«ThinMat» Company «Ensto» par 100Vt/m2 intended for use in well-insulated rooms with tiled or require limitations on the power of the sexes (such GVLV). “Thin mat” at 160 W/m2 used in wet or poorly insulated buildings with concrete, tiled or stone floors. Each of them, if necessary, is completed with a specially designed thermostat.

If you have already decided to make the house floor heating in commercial offices “MPO Wiring” technical consultants will help you choose the right area and the electrical characteristics of a set of commodity group P90. In addition, they recalled that in our range have appeared more and Danish heating «DEVI» of the world’s leading manufacturer of floor heating systems (commodity group P93).

And if you have not yet decided, we recall, the legs must be kept warm, if there is a fear that his head would not stay in the cold. “Warm floor” for this – the best remedy.

The habit of warm water in particular is making itself felt in the summer, when the sultry weather background in conducting prevention hot water, but in a village house or estate shestisotochnoe warm water does not centrally held.

Therefore the question of “to wash or not wash (yourself and dishes) from the category of classic should go into the practical level (cold or hot), bring in one of the sales offices MPO Electrical and where to stand squarely faced with the choice of a wide range of water heaters (commodity group B98 ) to suit you in performance, electrical characteristics and size.

First you have to think: what to choose. Water Heaters closed connected directly to the cold plumbing lines, work under pressure and feed water to several nearby points (in the kitchen and shower, for example). Units are connected via an open three-way tap to the plumbing for supplying hot water at one point, with the output of water is always open.

Water heaters are instantaneous or cumulative. In flowing water is not retained, only heated when it passes through the heat exchanger – the hotter, less consumption, but quickly, so power consumption is quite high. Used in residential and office spaces with a small consumption: 3,5-5 kW allow in a few minutes to get 1,8-3 liters per minute (for washing and dishwashing). Do not need regular maintenance, but require an additional machine at 32-40 amp, single supply wire in 2,5-4 “square” and grounding. If the computer you are still at 2,5 kW – will have to be replaced.

In the storage units to heat 30 liters of water from 12 to 75 degrees (for washing the family, washing dishes and for a short shower rather) is required from 15 minutes to an hour, 100 liters will warm to 3,5-4,5 hours. On the other hand and cools it slowly, like a thermos (half a degree per hour: it makes sense to heat water at night when dvuhtarifnom counter). You can connect to an ordinary power outlet: even 150-liter water heaters consume no more than 1,5-2 kW. That is, they are particularly good for low water pressure and poor wiring. But the need to periodically clean the heating elements from scale and replacing the magnesium anode, which prevents deposition of salts.

Excess pressure in the tank is discharged through the drainage hole safety valve. And when will block and cold water (temporarily), leakage from the unit prevents the check valve. But if the water in the tank is still not proved, the heater does not burn out due to set its thermostat.

Tankless water heaters usually have a protection class IP 24 (splash, kitchen and bathroom) or IP 25 (on the jets for a shower).

Cast iron radiators – very durable, but have a large thermal inertia, thus difficult to adjust the radiator and room temperature without proper temperature control of tankless water heater.

Steel panel radiators type – advantages: a large number of sizes, good heat dissipation, low water content, well-regulated radiator thermostat, have low thermal inertia. The main drawback – can not stand the fluid to be drained, do not like open systems and heating systems that use pipes resistant to the diffusion of atmospheric oxygen (for example, some types of polypropylene tubes).

Aluminum radiators – occupy an intermediate position between the steel and iron, combine virtually all the advantages and disadvantages of the previous groups of radiators. It makes sense to put in those cases where iron or steel, for whatever reasons do not meet the requirements. Significant addition – the quality of the radiator depends on the manufacturer and the quality of the raw material.

Bimetal radiators – Radiators with steel core and an aluminum jacket, designed to operate at high pressure coolant. The use of low-rise construction economically unfeasible.

Steel tubular radiators and convectors – as well as bimetallic designed for multi-storey building. Not sufficiently heat transfer surface area, and, consequently, low net power.
