How to choose the correct radiator power?
The efficiency of heating depends on the correct operation of individual elements of the entire system. The heart is of course the selected energy source, while the direct sensations are provided by elements located in individual rooms. The final element is radiators , but in order for the apartment to be really warm, it is necessary to match the appropriate variant.
One of the most important parameters to consider is the power of the radiator. It is selected based on individual factors, among which the most important is the heat demand. This factor depends on additional issues, such as the level of thermal insulation of the building, the materials used for construction or the construction technology. Special calculators available online are a great help. They determine the heat demand, taking into account factors such as the level of the building's storeys, the size of the rooms, the location of the building or the number of external walls.
The type of installation used is also of great importance. Heating can have two sources - side or bottom.
How to choose a radiator for a 25m2 room?
When choosing the right radiator, in addition to the size of the room, you also need to consider the external walls, windows and the expected temperature that should prevail every day. Due to the fact that individual characteristics must be taken into account, in case of doubt the best solution is the help and advice of a specialist.
In addition to the square footage, you should also take into account the specifics of the interior (number of windows, balcony doors, external walls) and the location of the radiator.
In order to properly select the power of the device, the most common method is the estimation method. It assumes that the available square footage should be multiplied by the value needed to heat an area of 1m2 or 1m3. Assuming that the final temperature will be around 21-22 degrees, the room has at least one window and an external wall, then the minimum power of the heater should be no less than 80-100 W/m2.
How to choose a radiator for a 20m2 room?
A radiator for a room with an area of 20 square meters is selected in a similar way. It will be necessary to estimate the potential heat losses, which will not be high with good insulation. With a value of 50 W/m2, the obtained value must be multiplied by the size of the room. This means that the optimal choice will be a device with a power of 1000 W. However, if the room is located in an old building, where the degree of thermal insulation is significantly lower, then the heat losses may be significantly higher, which means that a radiator with a higher power output will have to be installed.
