chose radiator material In the category building materials and construction Many people are interested in knowledge and learning about many subjects, this knowledge may be vital at some point in your life, attention enough, and dive into more detail more articles and learn more information about chose radiator material.
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.
