Find the ideal Large Double Radiator Online

If you’ve been looking for a radiator more on the large size, at Stelrad we have multiple sized radiators including steel panel, vertical and designer large radiators. No request is too big and we know all homes can vary in room size, so browse through our radiator collection to find the perfect fit for any room. Browse and buy online and get free delivery with any order above £200 whether you need large upright radiators for your bathroom or a steel panel option for your living room.

Sometimes, a standard size radiator just looks out of place in a large room and will also struggle to provide adequate heating throughout. If you’ve found getting the right size a challenge, we can help you here at Stelrad. Many of our ranges are available in a variety of sizes, with large radiators considerably bigger than many standard or traditional options. We can provide large radiators up to a maximum dimension of 600mm x 2400mm depending on the collection. If you are looking for a steel panel radiator, you choose up to 700mm x 2000mm which will provide sufficient heating coverage, such as the Softline Compact that comes with a 15 year warranty.

Of course, if you have a very large, open plan room design, you may need to incorporate more than one large radiator. A large double radiator can provide further heating coverage thanks to its double panel design. You can use our radiator size calculator to find the best options for your room and filter out those that wouldn’t be suitable. You’ll also be able to calculate the heat loss expected for the room you want to install the large radiator in. Use our heat loss calculator to work out the BTU (British Thermal Unit) requirement for the room before purchase.

Discover Large Horizontal Radiators

For something different to the norm, large horizontal radiators are a great addition if you have plenty of vertical wall space. Perfect for a kitchen layout where you may have less space due to appliances and storage or a bathroom, large upright radiators will provide excellent heating despite their orientation being different to classic designs. You’ll also be able to find large horizontal radiators that can be used as towel rails, providing added functionality. One of the largest sizes of large upright radiators we provide is 2500mm x 444mm, such as the Vita Column vertical radiator.

If you can’t find the exact size you’re looking for, don’t hesitate to contact us and we’ll help you get what you need in no time.

FAQs

Large Radiators FAQs

How Do I Check If a Large Radiator Will Fit My Room?

Open Close

If you are unsure about the size you need, whether it’s a large room or a compact one, you can use our radiator size calculator to match products to your requirements. You’ll need to measure the wall space where you want the large radiator to go as well as the gap between connecting pipes so that you can easily install. If you’re looking for vertical options, ensure you’ve measured the vertical wall space you have too and decide on how much of the space you want the radiator to take up.

Can a Radiator Be Too Big For a Room?

Open Close

Some designs of radiators may look overly large or small depending on the room. A large double radiator, for example, may look too bulky if in a small room, so finding the right fit is essential. When taking measurements, it’s best to allow plenty of space around the radiator so the wall isn’t completely filled. Also, choosing the wrong size radiator may not heat the room adequately or be energy efficient, meaning having to run for longer to heat larger rooms if too small and vice versa.

Are Large Radiators Expensive to Run?

Open Close

This will depend on many variables and how well insulated the room is. If you have a room that is single glazed compared to double glazed, the heat will escape much quicker and ultimately cost more to keep at a comfortable temperature. By working out the BTU (British Thermal Unit) requirement, you can determine how much energy you need to heat a room. You can do this using our heat loss calculator. Generally, choosing a large radiator will mean you can heat a room quicker than with a small one, so you won’t have to run it for as long. However, room sizes vary, so it is best to calculate heat loss before purchasing.
