Aluminium Radiators

There's more to choosing an aluminium radiator than picking a shape and colour. The right option depends on how you heat the room, the output you need and the system it will connect to.

These FAQs cover the main things to check before you order.

 

What are the benefits of aluminium radiators?

• Fast heat-up times - Aluminium is an excellent conductor of heat, allowing radiators to warm up quickly and bring your room to a comfortable temperature sooner.
• Energy efficient - Their speedy heat-up times mean aluminium radiators can be particularly efficient when used with modern, responsive heating systems, helping you heat your home without unnecessary energy use.
• Lightweight and easy to install - Aluminium is significantly lighter than steel, making these radiators easier to handle and install, particularly where wall weight is a consideration.
• Low water content - Aluminium radiators require less water to heat effectively, helping them reach temperature quickly and making them a responsive choice for modern heating systems.
• Environmentally friendly - Aluminium can be recycled repeatedly without losing its key properties, making it a more sustainable material choice for your home.

 

Are aluminium radiators better than steel radiators?

Aluminium generally heats up and cools down more quickly, while steel is widely used across a huge range of radiator types. The right choice depends on your heating system, the output your room needs, your available wall space and your budget.

 

What size and output do I need for an aluminium radiator?

When choosing any radiator, always start with the amount of heat the room needs. 

For a central heating radiator, use our BTU calculator to find the required output, then choose a model that meets it and fits your available wall space. 

For an electric aluminium radiator, check the wattage instead.

 

Can I use aluminium radiators with my existing heating system?

Aluminium radiators can be used with many central heating systems, including systems that have radiators made from other metals.

The system’s water needs to be treated correctly, though. Check the manufacturer’s instructions and make sure the radiator is suitable for your system before it's fitted.

 

Do aluminium radiators need corrosion inhibitor?

A wet heating system containing aluminium radiators should use a corrosion inhibitor suitable for aluminium and mixed-metal systems. Aluminium doesn't rust in the same way as steel, but it can still corrode if the system water isn't properly treated.

 

Are aluminium radiators cheaper to run?

Not necessarily. While aluminium's quick response can help you control the room temperature more closely, the material alone doesn't decide what your heating costs. What you pay depends on how you heat the room, how powerful the radiator is, how quickly the room loses heat and how long you leave the heating on.
