Radiatoryi for heating systems

Radiator, konvektor, the battery, “an accordion under a window”. As though we named established in our apartment or a country house heating devices, we from them always wait for one — heat and a cosiness, conformity to an interior, long and non-failure operation. However attempt to satisfy these simple consumer requests in practice appears exigeant. We will try to understand why.

Problem of a choice of heating devices, first of all, difficult enough engineering problem. And only after its decision mdash; selection of a radiator answering to all necessary specifications (working and opressovochnoe pressure, teplootdacha, an operation mode), it is possible to start to operate with absolutely other terms: the size and the form, conformity to an interior, colour scale etc.
Long time for the consumer both these problems were decided automatically, and with an obvious technical priority. Driving to new apartment, we met or to a pain familiar pig-iron pigs which were there and then covered with furniture because of impossibility to reconcile to their shape, or metal accordions, expect heat from which the incorrigible optimist could only. But it is necessary to give due to the Soviet engineers: they perfectly knew characteristics of the centralised systems of heating, and the main task — to supply the service life of the heating device proportionate to the period of operation of a building, — they decided successfully enough. Radiator failure, excepting emergency cases of defrosting of systems of heating, was the phenomenon the extremely rare.
All was changed after the consumer felt the owner of the dwelling, doing not wish to limit itself to the decisions offered by builders, and the market could offer it possibility of a choice of heating devices. Priorities have radically exchanged — the design question left on the foreground. Replacement of obsolete radiators by beautiful, modern, aluminium and steel radiators of import production has acquired mass character.
At the initial stage very few people was interested in technical characteristics of these radiators and degree of their applicability in the Russian centralised systems of heating as all necessary certificates had the majority of import heating devices, and selling firms strenuously advertised advantages of the goods. First of all were mentioned fine design and high teplootdacha, and words about that, how many years the given radiator will please the owners.
Only after cases of failure of the heating devices, accompanied by notable financial losses, conflicts to neighbours and necessity again to change radiators there were ordinary practice, both consumers, and sellers have started more osoznanno to approach to this question.
Let’s try to define the basic technical characteristics on which it is necessary to pay special attention at a choice of the heating device.

Appointment. Often enough in technical characteristics, handbills, passports on an item the manufacturer or the seller defines a scope of the equipment. Look it can as follows: “the Given kind of radiators is intended for application in the independent and-or centralised systems of heating of inhabited, administrative and public buildings”. For simplicity it is necessary to understand urban apartment as the centralised system of heating, and under independent — your country house with own boiler installation. Remember that for heating devices is very big difference. If in the passport on an item accurately it is not registered, that it is intended for application in the centralised system of heating, do not acquire it for installation in the apartment: it can become not only heat source, but also a source of the big troubles for you and your neighbours.
Material. The first natural question which arises at each buyer at the sight of the heating device which has liked it: of what it is made? For today in the Russian market the radiators executed from following materials are presented:
Aluminium
Pluses: high teplootdacha, easy weight, modern design;
Minuses: rigid requests to quality of the heat-carrier and observance of modes of operation;
Bimetal (a steel + aluminium)
Pluses: the easy weight, modern design is adapted for work in the central systems of heating, high teplootdacha;
Minuses: the made narrower channels of passage of the heat-carrier;
Steel (panel and tubular radiators)
Pluses: modern design, possibility of a choice of colour and the form for steel tubular radiators;
Minuses: rigid requests to quality of the heat-carrier and observance of modes of operation;
Pig-iron
Pluses: the maximum service life — does not depend on quality of the heat-carrier;
Minuses: the weight is sensitive to hydroblows.

Pressure. “Name, please, parametres of the worker and opressovochnogo pressure in your system of heating.” This question sellers of the heating equipment like to confuse the potential buyers and by that to shift on them the share of responsibility for a choice of this or that kind of radiators. Actually in most cases this question is decided easily enough. If you are the happy owner of individual system of heating parametres of pressure can not excite you at all — any of the heating devices which have liked you will meet requests on pressure. With room variants business is more difficult, here again really is better to spend some time for the coordination of this question with ZHEKom which should grant you the exhaustive information in this matter. With the big share of probability pressure in your system can be defined and to that for type of heating devices has been established in your apartment initially, at a building stage. If it were the Russian pig-iron radiators working pressure does not exceed 6 atm, and test 12. If at you stand konvektoryi — a pipe with nasazhennoy on it a steel lattice, — that most likely, an indicator of working pressure at you more than 10 atm, and test — more than 12. Parametres of pressure for a radiator interesting you are indicated in advertising materials and the passport an item.

Teplootdacha. Acquiring a radiator it is not necessary to forget about the ultimate goal — to heat your premise. Thus the simple and clear word "heat" starts to be measured in watts, and your apartment or a cottage in cubic metre on which heating the certain quantity the watt is required, produced by that heating device which you acquire. To try to count independently or at least to trace all this chain — business ungrateful. Therefore in this question we advise to adhere to following rules:
Thermal account of your country house or summer residence is better to entrust with experts. It is desirable to deal with the company offering all complex of services: the project, a complete set, installation, guarantee and service. Otherwise in that case when to you will seem, that the temperature range in your house mismatches your submissions, it will be difficult to find someone with whom it is possible to solve this problem. Guilty it can appear both the designer, and the expert in supply, and the assembler. And each of them will confidently show on the colleague. The only thing with what it is necessary to be defined independently, is a material, a design and design of a radiator. From the first indicator, the price of your system of heating hardly depends on the second — appearance of a premise.
At a choice of the heating device for apartment most easier to start with figure 100 watt on 1 square metre of the area of a premise, except for non-standard situations (ceilings above 3 metres, angular and incorporated rooms). Teplootdachu one section or a standard size of the radiator chosen by you it is possible to specify at the seller, in advertising materials or in the passport on an item. It is necessary to remember also, that in advertising materials of the majority of sellers of the heating equipment it is underlined teplootdacha the radiators, calculated, proceeding from the maximum indicators of temperature of the heat-carrier (100oS) on an input in a radiator, that actually meets extremely seldom.Julia GOSPODINOVA Source: "the Building Expert" #16 (2003)
