To date, there are more than five dif­fer­ent types of radi­a­tors for home, office and oth­er premis­es. They dif­fer from each oth­er in the mate­r­i­al from which they are made, as well as in shape. Radi­a­tors are steel, cast iron, alu­minum and bimetal­lic. In shape, they can be tubu­lar, sec­tion­al or pan­el. The mate­r­i­al of the bat­tery affects the heat trans­fer, and the shape affects the cir­cu­la­tion of warm air. The com­bi­na­tion of these fac­tors forms the cli­mat­ic con­di­tions in space. In this col­lec­tion, we will con­sid­er cast iron radi­a­tors.

Mod­ern tech­nolo­gies and design solu­tions have breathed new life into these devices. If ear­li­er they had a very unat­trac­tive appear­ance, today you can choose a mod­el for almost any inte­ri­or. In addi­tion, they have the longest ser­vice life, which aver­ages about 50 years. Cast iron bat­ter­ies with­stand very high water pres­sure, allow most of the heat to be trans­ferred not through con­vec­tion, but through ther­mal radi­a­tion, and are prac­ti­cal­ly not sub­ject to cor­ro­sion. The devices are con­nect­ed to the cen­tral heat­ing sys­tem in apart­ment build­ings, and if we are talk­ing about a pri­vate build­ing, then there is a need to lay a line. All these fea­tures make them high­ly com­pet­i­tive in the radi­a­tor mar­ket. How­ev­er, they also have a num­ber of dis­ad­van­tages. In par­tic­u­lar, this is a lot of weight, com­plex assem­bly and instal­la­tion, as well as the prob­lem­at­ic clean­ing between sec­tions.

Top 10 rating according to KP

1. Viadrus Bohemia 450/220

Our rat­ing is opened by a design mod­el from the man­u­fac­tur­er Viadrus. It is able to with­stand high water pres­sure and is extreme­ly resis­tant to cor­ro­sion. It can be used in sys­tems with both forced and nat­ur­al cir­cu­la­tion due to the large diam­e­ter of the through holes and low hydraulic resis­tance. Stan­dard equip­ment — ten sec­tions-ribs, which are primed with light gray enam­el. The weight of one rib is 11.4 kg.

2. Konner Modern 500

This mod­el dif­fers in com­pact­ness which the major­i­ty of com­peti­tors can­not brag of. The out­er sur­face of the radi­a­tor is per­fect­ly processed and has no extra bulges. In appear­ance, the mod­el resem­bles a stan­dard alu­minum con­struc­tion, but seri­ous­ly sur­pass­es it in qual­i­ty.

3. RETROstyle TOULON 500/110

The most impor­tant qual­i­ties of the Toulon radi­a­tor are reli­a­bil­i­ty, func­tion­al­i­ty and com­pact­ness. The geom­e­try of hard lines and a well-defined sil­hou­ette will per­fect­ly fit into the inte­ri­or in grunge, loft and hi-tech styles. In addi­tion, the mod­el is char­ac­ter­ized by excel­lent heat dis­si­pa­tion and the abil­i­ty to retain heat for a long time. The radi­a­tor is ful­ly adapt­ed to the fea­tures of our heat­ing sys­tems.

4. Viadrus Kalor 500/110

This mod­el is very pop­u­lar with cus­tomers due to its design. Out­ward­ly, it resem­bles the domes­tic mod­el MS-140, which in Sovi­et times was found in every home. The fac­to­ry equip­ment of the Viadrus Kalor 500/110 con­sists of a bat­tery with ten fins. Addi­tion­al com­fort dur­ing the oper­a­tion of the radi­a­tor pro­vides a built-in ther­mo­sta­t­ic valve. It allows you to imple­ment the con­nec­tion “from the floor” or “from the wall” direct­ly above the floor.

5. Alpine Air History 500

The design radi­a­tor of this mod­el is intend­ed for heat­ing of rooms of all types. The bat­tery has a soft and uni­form heat­ing, and also absorbs the sounds of water cir­cu­la­tion. The prod­uct is made of high qual­i­ty cast iron, which is immune to cor­ro­sion and primed with high qual­i­ty var­nish. It comes with any num­ber of sec­tions.

6. STI Nova 500 x7

This mod­el is a mod­ern cast-iron radi­a­tor, which is designed for use in heat­ing sys­tems of res­i­den­tial build­ings, pub­lic and indus­tri­al build­ings, cot­tages, etc. High effi­cien­cy is achieved due to the increased sur­face area and small vol­ume of coolant. The sur­face of the radi­a­tor has a heat-resis­tant white poly­mer coat­ing. The devel­op­ment ful­ly com­plies with all GOST stan­dards.

7. Ogint 500

This radi­a­tor is made from high qual­i­ty cast iron. The out­er sur­face of this mod­el is cov­ered with a pro­tec­tive enam­el lay­er. The bat­tery is able to effec­tive­ly with­stand water ham­mer. It is ide­al for use in water heat­ing sys­tems for res­i­den­tial, indus­tri­al, admin­is­tra­tive and med­ical build­ings. The man­u­fac­tur­er pro­vides a two-year war­ran­ty on the radi­a­tor.

8. Exemet Neo 4–660/50

A high degree of heat trans­fer in this mod­el is achieved due to the pres­ence of four “columns” in depth for each sec­tion. This radi­a­tor is per­fect for replac­ing old bat­ter­ies, as it has a stan­dard cen­ter-to-cen­ter dis­tance for Russ­ian heat­ing sys­tems. This mod­el is deliv­ered assem­bled in a floor ver­sion.

9. RETROstyle DERBY 500

Unlike oth­er mod­els of the RET­ROstyle line, this radi­a­tor is com­plete­ly devoid of pre­ten­tious­ness. Lacon­ic and aes­thet­ic, it will per­fect­ly fit into any inte­ri­or. The radi­a­tor is able to with­stand pres­sure up to 12 atmos­pheres (or ≈10 bar). Anoth­er inter­est­ing fea­ture is the abil­i­ty to self-paint the radi­a­tor in any col­or. This will allow you to imple­ment even the most dar­ing design deci­sions.

10. MS-140 500

Mod­el MS-140 is a clas­sic cast-iron radi­a­tor, as we are used to see­ing it. It is intend­ed for use in heat­ing sys­tems with nat­ur­al or forced cir­cu­la­tion. Its main advan­tage is dura­bil­i­ty. Anoth­er dis­tinc­tive fea­ture of this bat­tery is the large inter­nal sec­tion of pipes and sec­tions, which will allow it to work for a long time with­out clean­ing. In addi­tion, these radi­a­tors are char­ac­ter­ized by increased iner­tia (they cool down longer after turn­ing off the heat­ing).

How to choose cast iron radiators

Choos­ing a cast iron radi­a­tor will not be a has­sle if you take into account some details. For clar­i­fi­ca­tion on this issue, “Kom­so­mol­skaya Prav­da” turned to the leader of the YouTube chan­nel on con­struc­tion and fin­ish­ing mas­ter Pavel Sidorik.

The best alu­minum heat­ing radi­a­tors

Alu­minum radi­a­tors are a great alter­na­tive to old cast iron radi­a­tors.

Required heat

Ini­tial­ly, you should decide where the radi­a­tor will be installed. For a typ­i­cal room with one out­er wall, one win­dow and a stan­dard ceil­ing, there is an opti­mal for­mu­la. It allows you to cal­cu­late the required num­ber of sec­tions and looks like this:

N = Sx(100/P), where N is the num­ber of sec­tions, S is the area of ​​the heat­ed room, and P is the heat out­put of the device

You should also take into account the iner­tia fac­tor of cast-iron radi­a­tors, these mod­els warm up for a long time, but they retain heat well even dur­ing inter­rup­tions in hot water.

Installation method

Before buy­ing, be sure to pay atten­tion to which instal­la­tion method is pro­vid­ed by the man­u­fac­tur­er. So, most mod­els are mount­ed on the wall, but there are excep­tions when the radi­a­tor is installed on the floor on spe­cial legs. Some man­u­fac­tur­ers pro­vide both options.

Nuances

In addi­tion to the above fac­tors, the weight of the bat­tery should also be tak­en into account. Nat­u­ral­ly, a sec­tion­al type mod­el will be much lighter than a mono­lith­ic one. How­ev­er, if you set­tled on the lat­ter option, then for instal­la­tion you will need spe­cial brack­ets that take up addi­tion­al space. Water pres­sure also plays an impor­tant role. In an aver­age mul­ti-storey build­ing, it is about 9–10 atmos­pheres. It is bet­ter to pur­chase a bat­tery with a pres­sure mar­gin of up to 12 units. Some man­u­fac­tur­ers indi­cate pres­sure in atmos­pheres, some in bars. It is worth remem­ber­ing that 1 atm ≈ 1.01 bar.

Design

Let’s move on to the aes­thet­ic part. To date, man­u­fac­tur­ers offer var­i­ous vari­a­tions in the appear­ance of cast iron bat­ter­ies. So, some retro-style mod­els can be com­pared to works of art. Their sur­face can even be dec­o­rat­ed with an orna­ment. How­ev­er, the cost of such heaters is quite high. If you decide to stick with the clas­sic cast-iron bat­tery, con­sid­er hid­ing it behind a dec­o­ra­tive grille.
