Radiator Design – central heating radiators for every room

Selecting central heating radiators is a technical decision that determines the thermal stability and hydraulic balance of a domestic system. Our collection is engineered for wet systems, focusing on emitters that provide consistent heat while integrating into the specific architectural requirements of UK properties. By prioritizing units with standardized pipe centres, these radiators function as direct, high-performance replacements for older, less efficient components, minimizing the need for complex plumbing alterations. It is a technical response to the demand for modern thermal density within existing infrastructure.

The range handles diverse spatial challenges through geometry-first engineering, from high-output vertical units for restricted wall sections to horizontal models optimized for under-window placement. Each unit is vetted for its thermal delivery across a wide spectrum of outputs, ensuring reliability in everything from compact en-suites to expansive, open-plan environments. Furthermore, the low-water-content design of our modern panels ensures rapid response times to thermostat adjustments, enhancing overall system efficiency. Available in over 200 RAL Classic colours at no additional cost, these radiators integrate as permanent, functional elements of your interior architecture. It is a dependable choice for those who demand professional-grade precision and a seamless transition to high-efficiency heating.

Do all radiators work with central heating systems?

No. A radiator has to be designed for a wet central heating system to work with a boiler. Most standard radiators are, but electric-only models won’t work unless they’re specifically made as dual-fuel.

How do I know what size radiator I need for my room?

It really comes down to calculating how much heat the room needs. This is worked out in BTUs and depends on the room size, ceiling height, insulation, and how many windows there are. Once you have that number, you simply choose a radiator that meets or slightly exceeds it.

Are modern radiators more efficient than old ones?

Yes, in most cases. Modern radiators tend to heat up quicker and spread warmth more evenly than older models, especially when used with modern boilers and thermostatic radiator valves (TRVs). Swapping out very old radiators can make a noticeable difference to comfort and efficiency.

Can I replace just one radiator without changing the system?

Yes. You can change a single radiator without touching the rest of the system, as long as the new one is the right size and works with your existing pipework. This is a fairly common job in UK homes.

What’s the difference between single and double panel radiators?

A single panel radiator is slimmer and gives off less heat, while a double panel radiator produces more heat using the same wall space. Double panel radiators are very common in UK living rooms and larger rooms.

Do I need thermostatic radiator valves on central heating radiators?

They’re not strictly required, but they’re strongly recommended. TRVs let you adjust the temperature in each room separately, which improves comfort and helps avoid wasting energy.

Will new radiators reduce my heating bills?

They can, yes. Properly sized modern radiators allow the boiler to work more efficiently and heat rooms faster. They won’t magically halve your bills, but over time they can lead to noticeable savings.

Can central heating radiators work with low-temperature systems?

Yes, they can — but they usually need to be larger or have a higher output. Low-temperature systems, such as heat pumps, rely on radiators with more surface area to deliver the same level of warmth.

ROOM RADIATORS – CENTRAL HEATING RADIATORS

The central heating radiators shown here are designed for wet central heating systems, the most common form of heating in the UK. These radiators utilise hot water generated by a boiler—whether a combi, conventional, or system boiler—to distribute warmth efficiently throughout a room.
Because our room radiators feature a sophisticated appearance, there is no need to conceal them behind radiator covers or cabinets. These designer units are engineered to make every room comfortable while serving as a visual complement to your interior decor.
Our range includes several distinct types of central heating radiators. Tubular radiators remain highly popular due to their versatile profiles and configurations. For those who prefer a traditional aesthetic, our modern steel column radiators replicate the classic look in over 200 colours. Additionally, panel radiators are a frequent choice for those seeking a familiar, minimalist wall-mounted solution.
Selecting the right room radiator depends on both personal style and spatial constraints. For vertical radiators, width is the primary consideration for narrow wall sections, whereas horizontal models are sized to fit specific areas, such as under windows. With many models available in thousands of size variations, they offer the flexibility of bespoke radiators. Most of these coloured radiators are general-purpose units, performing reliably in kitchens, bedrooms, and living areas alike.
