Aluminium radiators are not particularly prone to corrosion, however this does not mean they absolutely never corrode. The exterior of aluminium radiators are covered in a paint finish which means that surface of the radiator will not react with the air. Because of this, rust and corrosion is very rarely a problem.
What are the disadvantages of aluminium radiators?
Like all materials, there are also some cons when it comes to aluminium radiators. These include: They can lose heat faster: While aluminium radiators are fantastic conductors of heat, this has another side; they can also lose heat faster than stainless steel models.
How long does an aluminum radiator last?
between 8 and 10 years
How Long Do Aluminum Radiators Last? It might surprise you to know that when compared to copper-brass radiators, aluminum ones generally last longer. In fact, most aluminum radiators usually last between 8 and 10 years.
What is the advantage of an aluminum radiator?
Aluminium radiators transfer the heat from the water to the air in the room faster than steel radiators. This means that they require less heated water from the boiler and will be faster to respond to changes in the room heat requirement, hence reducing any wasted heat.
How do you protect aluminium radiators?
The outer surface of an aluminium radiator is always coated in paint, therefore the aluminium itself won’t come into contact with oxygen. If it should, for example through small scratches overtime on your radiator, a new layer of aluminium oxide will form which protects the metal underneath, protecting your radiator.
Are aluminium radiators worth it?
Very energy efficient
Aluminium is an excellent conductor of heat, which makes it a brilliant metal to manufacture radiators out of. As aluminium conducts heat so well, it means that aluminium radiators can get up to your desired temperature more quickly than radiators made out of other materials.
Are aluminium radiators better?
Aluminium conducts up to 5 times more efficiently than steel meaning two things, your rooms will warm up faster, and also cool down quicker due to the metal reacting to dialling up or down of the thermostat more quickly.
Can you repair a aluminum radiator?
Aluminum radiators cannot be repaired like copper-brass radiators can. Additionally, the type of tanks and the location of the leak is important too.
How do I know if my radiator is aluminum?
Use a knife point to lightly scratch the tubes, if it copper you’ll see it. The end tanks are usually brass. Most of the newer ones will have aluminium fins, that’s fine since it’s not touching any coolant.
Are aluminum radiators better than plastic?
The aluminium core that rests within most plastic radiators is a little more durable, but even that isn’t as effective as the brass and copper radiators that have been widely used for years.
What are the disadvantages of aluminium?
What are disadvantages of Aluminium? Disadvantages : Aluminum requires special processes to be welded. It is abrasive to tooling, or more accurately, the aluminum oxide coating that forms upon it is. It is more expensive than steel.
Are aluminium radiators better than copper?
The aluminum radiator is 100% aluminum furnace brazed without any insulating solder. That is why aluminum radiators work better than copper ones. If you could build a copper radiator the exact same way we make the aluminum ones, it would work better than the aluminum.
Can I mix steel and aluminium radiators?
Yes you are right, don’t mix aluminum rads with steel/cast iron, and if you do don’t use fernox inhibitor :O.
What is radiator stray current?
In simple terms, stray current is a chemical/ electrical process which causes an electrical current to pass through a vehicle’s cooling system fluid. It can cause rapid damage to radiators and will indirectly cause problems with other engine components such as water pumps, thermostat housing etc.
How do you stop a radiator from corroding?
Key prevention tips
- Use corrosion inhibitor coolant and demineralised water only.
- Use the manufacturer’s recommended coolant.
- Ensure the system is adequately flushed during coolant change or replacing of parts.
- Don’t mix coolants — top up your coolant with the same pre-mix currently in the car.
Why are radiators grounded?
Why bathroom radiator earthing is important is to prevent electrocution, fire hazards and damage to the radiator and other appliances. Usually, you can see a thin wire going from the radiator to the ground. Is a radiator an extraneous conductive part?
How much better is an aluminum radiator?
An aluminum radiator does cool better than a copper brass radiator. For example, an aluminum radiator with 2 rows of 1″ tubes is equivalent to a copper brass radiator with 5 rows of 1/2″ tubes. Aluminum provides high efficiency, is lightweight, and has a longer life compared to copper brass.
Are aluminium radiators better for heat pumps?
Correctly sizing heat emitters
For example, with a low temperature system, such as an air source heat pump, a larger surface area is needed to effectively transfer the heat from the system and this is why underfloor heating or aluminium radiators can be the ideal solution when it comes to heat emitters.
How much more efficient are aluminium radiators?
15% less energy
Because of their thermal qualities, aluminium rads generally use lower amounts of water than their heat-emitting competitors. Again, this means that less energy is used to heat the water, less energy is needed to pump the water around your heating system and….you’re using less water.

How do aluminum radiators work?
These radiators are made by brazing thin aluminum fins to flattened aluminum tubes. The coolant flows from the inlet to the outlet through many tubes mounted in a parallel arrangement. The fins conduct the heat from the tubes and transfer it to the air flowing through the radiator.
