For a complete vertical radiator close to 300 mm wide, the EMKE 900 x 304 mm model is the only listed product that fits the search. It is a single-layer steel panel radiator with a stated 297 W output. The other listings are a radiator cover or replacement heating elements, not complete vertical radiators, so they should not be treated as equivalent options. Check the connection details and room-heating requirements before choosing.
| Product | What It Is | Best Suited For |
|---|---|---|
| EMKE 900 x 304 mm | Complete vertical panel radiator | Buyers seeking a compact radiator around 300 mm wide |
| 30 cm no-drill cover | Radiator cover | Buyers looking for a cover, not a heat source |
| 300 mm straight fin tube | Heating element component | Equipment repair or assembly where specifications match |
| 300 mm fin heater tube | Heating element component | Technical replacement needs requiring a specific voltage |
| Finned heating tube | Heating element component | Compatible equipment requiring a tubular element |
EMKE 900 x 304 mm Vertical Radiator

Best for: Buyers who need a complete, narrow vertical radiator close to 300 mm wide. This is the strongest match in the list because its stated dimensions are 900 x 304 x 52 mm, and the listing identifies it as a wall radiator for a bathroom, bedroom, or living room.
The single-layer steel panel has a stated heat output of 297 W and is described as suitable for rooms up to approximately 5 m². Listed installation details include a G1/2-inch connection thread, 50 mm axle spacing, an 85 mm distance from the wall, and a net weight of 7.2 kg. Its flat anthracite design may suit buyers looking for a contemporary appearance.
Limitation: The stated output and room-area guidance are product-listing claims, not a substitute for calculating a room’s heating needs. Confirm the connection arrangement and installation requirements before purchase.
30 cm No-Drill Radiator Cover

Best for: Someone searching for a cover or decorative radiator accessory rather than a radiator. The listing describes a metal cover intended to help shield walls from stains and smoke and provide a surface for display. It also claims its brackets direct heat into the room.
Measure the existing radiator before choosing a size: the listing says the cover length corresponds to the radiator length plus 10 cm. That makes careful measurement important, especially when fitting a cover in a narrow space.
Limitation: This product is not a complete vertical radiator and does not provide a stated heating output. Avoid choosing it as a substitute for a heat source; confirm its dimensions and fit with the seller’s specifications.
300 mm Straight Fin Heating Tube

Best for: A buyer sourcing a heating element for equipment or a compatible assembly, not someone who needs a ready-to-install room radiator. The listing describes a straight fin radiator heating tube with a 26 mm ceramic cap and a 300 mm size option. Listed power options range from 300 W to 900 W.
Limitation: The listing does not provide enough information to establish that this component can be used as a household vertical radiator. Check voltage, dimensions, electrical requirements, and equipment compatibility before selecting a version.
Stainless Steel Fin Heater Tube

Best for: Buyers looking for a tubular heating element with a specified electrical setup. The product name lists 110 V, 220 V, and 380 V versions, along with power options and a 300 mm length. The listing describes a 304 stainless steel tube with fins.
Limitation: Product details are inconsistent: the name lists several voltage and wattage choices, while the selected variation text references 380 V and 350 W. Confirm the exact configuration before ordering. This is a component, not a complete room radiator.
Finned 304 Stainless Steel Heating Tube

Best for: Buyers replacing or sourcing a tubular heating element for equipment whose requirements match the part. The listing describes a 304 stainless steel finned tube, several voltage and power choices, and a range of sizes. It also claims the element heats rapidly and is designed for installation in compatible equipment.
Limitation: The listing does not identify this as a complete vertical radiator or provide enough detail to verify a specific system fit. Confirm the size, voltage, power, and installation requirements with the equipment documentation.
Buying Guide: Choosing A 300mm Wide Vertical Radiator
Do you need a complete radiator or a component?
A complete radiator is a heat-emitting unit designed to be installed as part of a heating system. A finned tube is a component, while a radiator cover is an accessory. For a room-heating purchase, prioritize a product explicitly described as a complete radiator and verify its installation details.
How should you compare dimensions?
Check the radiator’s width, height, and depth, then compare them with the available wall space. A product listed as 304 mm wide is close to 300 mm, but it may not fit an opening limited to exactly 300 mm. Also account for connection position and the space required for installation.
How much heat output do you need?
Use the stated wattage as one comparison point, not as a guarantee that a radiator will heat a particular room. Room size, insulation, windows, climate, and the broader heating system affect performance. The EMKE listing states 297 W and approximately 5 m², but buyers should confirm suitability for their room.
What connection details should you confirm?
Check thread size, connection position, pipe spacing, and wall clearance against your existing system or installation plan. The EMKE listing specifies a G1/2-inch thread and 50 mm axle spacing. Have a qualified professional confirm whether these details match the intended installation.
Frequently Asked Questions
Is a 304 mm radiator suitable for a 300 mm space?
Not necessarily. A 304 mm-wide radiator exceeds a strict 300 mm limit. Measure the full available space and allow for installation clearances before choosing.
Which listed product is a complete vertical radiator?
The EMKE 900 x 304 mm product is the only listing identified as a complete vertical panel radiator.
Are the finned heating tubes alternatives to a room radiator?
No. They are listed as heating elements or tubular components. Their descriptions do not establish that they are complete room radiators.
Can a radiator cover replace a radiator?
No. A cover is an accessory for an existing radiator. It does not provide a stated heat output of its own.
What should I check before buying a narrow radiator?
Confirm its dimensions, heat output, connection type, pipe spacing, wall clearance, and compatibility with the heating system. Also verify that the product is a complete radiator rather than a cover or replacement part.
