The deliberate choice of a radiator for an apartment

What should I consider when choosing radiators for apartments

All engineering networks are its technological lifespan and city apartment heating system is no exception.Change is necessary not only central heating risers, but also end-device system - water heating radiators.Hike to a nearby building materials supermarket or walking in internet only complicate the problem of choice: all of these devices, if you believe the advertising, seem ideal.

recommend that you start with the product specifications, as the other attractive qualities of your purchase, you can find a variety of model range from leading manufacturers.

1. First of all, try to find you need the performance of devices, responsible for the comfort and warmth in your home.Make it a snap.According to the standards for our typical apartments Thermal power of the appliance should provide 100 watts per square meter.Working heat one section (P) radiator is listed in the data sheet (say 0,185 kW), yardage (S) of your dwelling is known (let it be 21 square meters).Then a simple formula: N = Rh100 / S, ie,for a complete heating of the room you need 185h100 / 21 = 11 sections of a selected radiator.
2. Now it is clear that the rate of heat transfer sectional device plays an important role, and it must be fought.
3. corrosion resistance of the material internal surfaces in contact with the coolant.For this indicator, the main materials heaters descending lines can be located as follows: cast iron - steel - aluminum.
4. Selecting a radiator for the apartment makes you wonder about its heat transfer, in fact, the main indicator of the performance of any heating device.Thermal conductivity of materials from the preceding paragraph is the opposite and therefore the issue is transferred to the design scope.

Selection of material and design radiator heating

Arte consider only some disadvantages of the various endpoints of urban heating systems.

Cast iron radiators.Initially, a high rate of thermal inertia, reactivity to adjust and control system.Low heat conductivity metal: up to 80% of the heat is transferred by radiation, that the working fluid at lower temperature adversely affects heat transfer.Convective heat transfer is practically not working.

Steel panel.Heat-conducting properties similar to cast iron, corrosion and poor.The inevitable deposition of corrosion products and lime slagging conducting channels over time, lead-pipes just scores of these units.

aluminum radiators for an apartment.In addition to all the well-known poor corrosion resistance in aggressive environments also have another drawback.The operating pressure of 10-15 atmospheres such radiators still holding, but limiting Compression 30-35 atm can crawl and leak in the connecting nodes.

Bimetallic radiators.The devices are relatively new, but has already won the sympathy of consumers.Technical characteristics of the models we have considered in a separate article, it is simply pay attention to the price factor.The average cost of comparable heat output of aluminum, iron and bimetallic sections of 300/370/600 rubles.There is a difference, and yet ...

Which cooler for an apartment, we recommend

Analysis radiators market, customer reviews and their own experience allows us to provide an optional message for the correct choice of modern heating equipment for your apartment:

• type: bimetallic with two wings convection;
• manufacturer: from rating-proven models;
• heat section: 180-195 kW;
• overall depth: 80-100 mm;
• center distance: 450-500
• number of sections: on the basis of the calculation.

Try to install such possible claimed 50 years in your home will be warm and cozy, and we rejoice with you.
