Whether you are building a new home or renovating an existing space, one vital consideration is your heating system. While an HVAC specialist is ultimately responsible for designing an effective solution, you can independently calculate the optimal number of radiator sections with our online Heating Radiator Section Calculator. Simply provide your room’s dimensions and other essential parameters.
Calculator Functions
This web-based tool is designed to determine the required heating radiator sections per square meter based on the power of each section. The calculator features:
The program calculates the number of radiator sections, the room’s total heat losses, the specific heat loss per square meter, and the heat output per individual section. All results can be saved as a PDF file or printed for your convenience.
Follow these steps to obtain your results:
When evaluating different radiator models, consider these key technical aspects:
There are four primary types of radiators available: steel, cast iron, aluminum, and bimetallic.
Steel Radiators – These units offer dependable heat output at a competitive price, though they might be less tolerant of hydraulic shocks and high pressure, and can be prone to corrosion. Steel models are commonly available in panel or tubular configurations.
Cast Iron Radiators – Known for their longevity, cast iron radiators are a staple in centralized heating systems. They deliver robust heat along with excellent resistance to corrosion and hydraulic shocks, although their slower response times and heavier weight may pose installation challenges.
Aluminum Radiators – Modern aluminum radiators, produced through casting or extrusion, are highly popular. They provide superior heat output with a lightweight design for easier installation, although they can be more sensitive to pressure fluctuations and rapid temperature changes.
Bimetallic Radiators – Combining an external aluminum shell with an inner core of steel or copper, bimetallic radiators offer outstanding performance. They ensure high heat output, solid construction, and excellent resilience against corrosion and hydraulic shocks, while remaining relatively light.
To achieve optimal thermal comfort, it is essential that radiators have a suitable heating surface to efficiently warm your room without overwhelming the boiler. Other important factors include the radiator’s construction material, which affects the heat transfer coefficient, and the water temperature within the system. Ultimately, the heat output depends on the radiator’s radiating surface, and the most efficient designs maintain steady performance even with fluctuating external temperatures.
For precise calculation of the required radiator sections, use our online Heating Radiator Section Calculator. By accounting for both room area and volume, this tool assists in establishing the ideal section count for effective heating in homes and apartments alike—suitable for both panel and alternative radiator types.
Glossary
Heating Radiator – A heating device consisting of individual sections—tubular or elongated elements—that channel a circulating heat carrier, typically water. It releases heat through convection, radiation, and conduction.
Heat Carrier – A liquid medium that transfers thermal energy within heating systems. Water is the most common medium in centralized and residential setups, while antifreeze solutions—generally based on propylene glycol (recommended by many manufacturers) or ethylene glycol (less advised)—are used in specific circumstances.
