What is a Single Radiator?
A single radiator has one panel for hot water or electric heating to pass through. These are often slimmer and less obtrusive, making them ideal for smaller spaces.
Benefits of Single Radiators
- Compact design — perfect for rooms with limited wall space.
- Faster heat-up time due to smaller water capacity.
- Generally more affordable than double radiators.
Drawbacks of Single Radiators
- Lower heat output compared to double radiators of the same size.
- May struggle to heat larger rooms efficiently.

What is a Double Radiator?
A double radiator features two panels, increasing its heat output significantly. They are slightly deeper but deliver more warmth, making them ideal for larger spaces or colder areas.
Benefits of Double Radiators
- Higher heat output — heats rooms faster and more effectively.
- Great for larger living rooms, kitchens, or areas with poor insulation.
Drawbacks of Double Radiators
- Bigger and bulkier — requires more wall space.
- Slightly higher purchase and installation costs.

Frequently Asked Questions
What is the main difference between single and double radiators?
Single radiators have one panel and are slimmer, while double radiators have two panels and produce more heat but are deeper.
Do double radiators cost more to run?
Double radiators use more hot water to heat, but they can heat rooms faster, which may balance out running costs depending on your usage.
Can I replace a single radiator with a double?
Yes, but you need to ensure your pipework and available wall space can accommodate the larger size and depth of the double radiator.
Which radiator is best for small rooms?
Single radiators are typically better for small spaces because they are slimmer and provide enough heat for compact areas.
Final Thoughts
Single radiators are best for small rooms and areas where space is limited, while double radiators are ideal for larger spaces that need a higher heat output. The best choice depends on your room size, layout, and heating needs.
