chose radiator material – Comfort and warmth – the main components of a cozy home , so modern apartments and homes well, can not be imagined without a radiator ( battery).
Now increasingly replaced bulky cast iron radiators come stylish and beautiful bimetallic battery ! It is not always even the most modern radiators will warm the house due to certain features of the device and your heating system.
To avoid such inconvenience and disappointment , please use our instructions when choosing a heating radiator.
Step 1. Check out the types of radiators
Modern radiators are of various kinds depending on the material of manufacture and construction. When choosing a radiator advise to pay attention primarily to the material section , because it affects the heat transfer material future batteries ( and , consequently, the temperature in the room ) , its severity and longevity
Cast iron radiator – radiator type , familiar to us from the Soviet era . Reliable and cheap sections of iron have more disadvantages than advantages – poor heat dissipation, large mass , the need for painting . However , the classic is always in demand when the budget variant heating. We strongly recommend the use of cast iron radiators with independent heating !
Steel radiator – the best option for heating a country or a private home . The fact that steel radiator ” not tolerate ” a centralized heating system , which is most common in apartment buildings – rusts when draining the coolant , can not withstand pressure during hydraulic testing , not react with oxygen , got through a piping system . In turn , steel radiators – modern with an attractive design panels have high heat and are relatively budget option heating. Do not recommend installing steel radiators in a damp room (eg bathroom) !
Bimetal radiators – despite the high cost of construction , recommended for all types of heating. Bimetal radiator is good to use – durable (steel pipe radiator is not subjected to chemical processes ) , with good heat dissipation ( the outer layer of aluminum heat transfer speeds ) , with a modern look . Recommended for homes with central heating system !
Aluminum radiators – consists of sections , the number of which is selected taking into account the features of the room . Plus aluminum radiators are high heat , ease of construction and rapid cooling . However, using these radiators to be careful – aluminum construction corrode from the hot water flowing through the pipes .
Step 2 . Determine how much power is required for the room
Defined the type radiator, you need to pay attention to the heat output , the value of which depends on the particular room. Purchasing radiator with bad or insufficient capacity for a particular room , freeze is not difficult.
Amount of power consumption depends on several factors:
– Size of the room ;
– The number of external walls and windows of the premises ;
– Type of house ( brick , stone );
– View windows ( wooden, plastic ) .
Thermal power for all types of radiators are different :
cast iron radiator – 80-150 watts ( for one section );
steel radiator – 450-5700 W ( for the entire radiator );
aluminum radiator – 190 W (for one section );
bimetal radiator – 200 W ( one partition ) .
So, for the typical panel houses ( with the height of the walls up to 3 meters, the window and the outer wall ) requires 1.7 kW of power for heating 10 m. m space . In new houses by 10 m. m accounts for 1 kW of power. But for space with two exterior walls is required not less 2.5 kW power consumption.
In combination with additional space heating devices (eg underfloor heating ) calculated radiator power must be reduced by the value of the power additional devices .
Knowing the thermal capacity and the amount of room you can determine the number of sections, each of which consists radiator. The approximate formula that calculates the number of sections N = S / 1,7, where N – number of sections , S – area of the room and the number of 1.7 is defined and its capacity radiator material.
Step 3 . Read the operating pressure
Operating pressure – an important indicator when choosing a radiator . Should immediately withdraw from the purchase batteries , which the working pressure is less than your heating system. Also selected radiator shall be designed to limit pressure (served during hydraulic testing ) . For multi-storey brick and private homes , this figure should be 3 atmosphere for panel residential buildings – 8 atmospheres for high-rise buildings (over 9 floors ) – 16 atmospheres.
Working pressure of various types of radiators :
cast iron radiator – 10-15 atmospheres ;
steel radiator – 6-8,7 atmospheres ;
aluminum radiator – 16 bar ;
bimetal radiator – 35 atmospheres.
Step 4 . Remember important details
Going to the store for purchase , you still remember some of the important things when choosing a suitable radiator :
– Important elements of modern radiator thermostat is ( automatic or manual ), and tap to release air and water shutoff ;
– Learn the value of working and test pressure in your heating system ( it can be done in your home serving organizations);
– Type of heating in your home ( one-and two-pipe is );
– Pipe sizes , of lead to the radiators ;
– The width of the radiator is usually determined by the width of the window opening ( sill ) and accounts for 75 % of the width of the window.
