Frequently Asked Questions
How does the 2046mm height of the Oscar Aluminium Radiator maximize thermal output in rooms with minimal wall width availability?
The Oscar 2046mm High model is the tallest technical solution in the range, designed specifically to solve the problem of heating large volume rooms where only a narrow vertical strip of wall is available. By extending the heat exchange surface to over 2 meters, it generates a massive "chimney effect" for convection. This allows even a narrow 420mm wide unit (5 sections) to deliver over 5400 BTUs, providing the equivalent heat of a large horizontal double panel radiator without occupying the floor space.
What is the precise heat output per section for the Oscar 2046mm model and how does this affect system design?
Each individual section of the Oscar 2046mm radiator produces approximately 1095 BTUs (321 Watts) at Delta T50. This extremely high output density means you can heat very large spaces with relatively few sections. For system design, this is critical; a 10-section model delivers nearly 11,000 BTUs. You must ensure your pipework flow rates are sufficient to supply this heat load, as a single Oscar 2046mm can demand as much energy as three standard bedroom radiators combined.
Why is the Oscar 2046mm radiator particularly recommended for low temperature renewable heating systems?
The Oscar 2046mm is an ideal emitter for heat pumps because it combines maximum surface area with high thermal conductivity. Even when the flow temperature drops to 40
What are the structural mounting requirements for installing a 2-meter tall aluminium radiator on internal walls?
Although the Oscar 2046mm is made from lightweight aluminium (making it lighter than cast iron), the sheer height creates a significant leverage moment on the wall brackets. You must use the supplied heavy-duty brackets and ensure they are fixed into solid timber studs or masonry. Using standard plasterboard toggles is not recommended. The top retaining bracket is technically critical to prevent the tall unit from tipping forward, while the bottom brackets bear the vertical weight load.
Does the 2046mm height require a specific flow diverter installation to prevent cold spots at the top?
Yes, for a radiator of this extreme height, internal water velocity is crucial. If connected via bottom opposite ends (BOE), gravity can cause the water to flow across the bottom rail without rising fully to the 2-meter top header. To solve this, a flow diverter (baffle) must be installed in the inlet. This forces the hot water to travel vertically up the first section to the top before cascading down the other columns, ensuring the entire 2046mm height is hot and preventing the top half from remaining cold.
What specific corrosion inhibitor regime is required to protect the Oscar 2046mm Aluminium radiator?
The Oscar 2046mm is sensitive to electrolytic corrosion if the system water pH is incorrect. You must use a high-quality "mixed metal" inhibitor (such as Fernox F1 or Sentinel X100) and maintain a neutral pH between 7.0 and 8.0. Standard steel inhibitors can cause high alkalinity, which eats away the aluminium oxide layer. Given the high value of these large radiators, annual checking of the inhibitor levels is a mandatory technical requirement to prevent hydrogen gas build-up and pinhole leaks.
What are the depth and projection dimensions I need to allow for when installing the Oscar 2046mm in a hallway?
The radiator sections themselves are 116mm deep. However, you must technically account for the wall bracket standoff. The total projection from the wall to the front face will be approximately 146mm to 156mm. In a narrow hallway or behind a door, this is a significant protrusion. You must measure the door swing arc carefully to ensure the handle does not strike the radiator, as a heavy impact on the aluminium fins could cause cosmetic or structural damage.
Is the Oscar 2046mm radiator suitable for high pressure district heating systems found in modern apartments?
Yes, the Oscar 2046mm is manufactured using a high-pressure extrusion process. This seamless vertical construction makes it technically capable of withstanding operating pressures far higher than standard steel panels, often rated to 16 Bar or more (refer to specific batch data). This makes it a perfect problem-solving choice for high-rise buildings or district heating networks where system pressures often exceed 6-10 Bar, ensuring safety and durability where other radiators might fail.
How does the low water content of the Oscar 2046mm improve the energy efficiency of my heating system?
Despite its massive size, the Oscar 2046mm holds a relatively low volume of water compared to a steel column radiator of the same output. This low thermal mass means the boiler or heat pump has less water to heat up initially. The radiator responds rapidly to thermostat changes
Can I install the Oscar 2046mm radiator horizontally if I have a wide wall space available?
No, the Oscar 2046mm is technically designed as a vertical radiator. The internal manifolds and flow characteristics are engineered for vertical water movement. Installing it horizontally would disrupt the convection currents (the fins would be horizontal, blocking airflow) and trap air pockets that cannot be bled out, leading to noisy operation and zero heat output. You must select a specific horizontal model (e.g., Oscar 440mm or 600mm high) for wide wall spaces.
