Lightweight and easy to install, aluminium radiators are particularly suitable for smaller spaces. Thanks to modern design research, they come in a variety of sleek and contemporary styles. Representing a significant share of the heating market, aluminium radiators have both advantages and drawbacks—let’s explore them in detail.
Which radiators are better: aluminium or steel?
One of the main reasons why aluminium radiators are a popular choice is that aluminium is one of the best heat conductors. This plays a crucial role in the thermal efficiency of this type of radiator. Specifically, aluminium radiators heat up very quickly, ensuring a warm and comfortable home while also improving energy efficiency.
- As they warm up rapidly, aluminium radiators reach the desired temperature in a short time.
- As a result, the boiler works less, reducing the amount of gas required and leading to lower energy bills.
However, aluminium radiators contain less water than other radiator types, meaning that the boiler needs to turn on and off frequently, which can have an impact on energy consumption.
In comparison, steel radiators take longer to heat up properly. A second important factor should be considered when choosing the best radiator for your needs. While steel radiators require more time to reach the desired temperature, they also cool down more slowly, continuing to provide warmth even after the heating system has been switched off.
Aluminium radiators, on the other hand, lose heat more quickly once the heating is turned off, making them a better choice for smaller spaces.
The thermal inertia of an aluminium radiator can be further enhanced with smart home heating solutions, such as smart thermostatic valves.
- These devices allow for intelligent heating scheduling based on daily, weekly, and hourly habits.
- They detect room temperature with precision and, when combined with a smart thermostat, ensure that your home remains warm and comfortable throughout winter.
Users can also set different temperatures for each room, depending on their specific needs and usage.
How long do aluminium radiators last?
The lifespan of an aluminium radiator, like those made from other materials, depends on proper care and maintenance, making it difficult to define a precise duration. However, modern painting and manufacturing techniques have significantly increased their resistance to corrosion.
On average, aluminium radiators last between 15 and 20 years. Their performance can also be improved with simple maintenance practices, such as bleeding the radiator to remove trapped air.
How to remove air from aluminium radiators?
Air bubbles inside the radiator can block the flow of hot water, preventing the radiator from heating efficiently. Fortunately, modern models make bleeding the radiator an easy process.
- Slightly open the bleed valve, placing a container underneath to catch any water.
- Let the water flow out slowly—there is no need to fully open the valve.
- Once a small amount of water has been released, close the valve securely.
- Check the boiler pressure, which should be between 1 and 2 bar after the operation.
What are the latest-generation radiators?
Aluminium and steel radiators fall into the latest-generation heating solutions, combining energy efficiency, aesthetics, and design in both shape and colour.
This ensures they seamlessly integrate into any environment. Additionally, if paired with smart thermostatic valves, their aesthetic appeal remains unaffected.
Smart thermostatic valves are not only designed for energy savings but also as stylish heating elements. They combine functionality with minimalist design, offering a wide range of colours and finishes to match any interior.
