Frequently Asked Questions
How does the 1846mm height of the Oscar Aluminium Radiator range specifically benefit rooms with high ceilings and significant heat loss?
The 1846mm height is technically optimized to deliver a massive heat output from a relatively small floor footprint. By utilizing the vertical wall space often found between tall windows or in double-height entrance halls, the Oscar 1846 creates a powerful convection current. This "chimney effect" draws cold air from the floor, heats it rapidly as it travels up the nearly 2-meter tall columns, and projects warm air into the room's upper volume, effectively solving the problem of heat stratification in large, high-ceilinged spaces where standard radiators would be ineffective.
What is the specific heat output per section for the Oscar 1846mm model and how do I calculate the total requirement for my room?
Each individual section of the Oscar 1846mm radiator generates approximately 1013 BTUs (297 Watts) at Delta T50. This is one of the highest outputs per section in the aluminium market. To calculate your requirement, take your room's total heat loss figure (e.g., 8000 BTUs) and divide it by 1013. In this example, you would need an 8-section model (producing roughly 8107 BTUs). This modular technical feature allows for precise sizing, ensuring you don't install an underpowered unit in a large room.
Why is the Oscar 1846mm Aluminium radiator considered a superior technical solution for heat pump systems compared to steel panel radiators?
The Oscar 1846mm combines two critical technical factors for heat pump efficiency: High Surface Area and High Thermal Conductivity. Heat pumps operate at lower water temperatures (35-45
What are the exact dimensions regarding depth and wall projection for the Oscar 1846mm radiator?
The Oscar 1846mm radiator sections have a depth of 116mm. However, this is not the total distance from the wall. You must technically account for the wall brackets which add approximately 30-40mm clearance. Therefore, the total projection from the wall to the front face of the radiator will be roughly 146mm to 156mm. This is an important consideration for installation in narrow corridors or behind doors, as the unit will protrude significantly more than a standard flat panel radiator.
Can the Oscar 1846mm radiator be installed on internal partition walls or does it require solid masonry?
Despite its imposing height and high heat output, the Oscar 1846mm is made from extruded aluminium, making it surprisingly lightweight. A 10-section model (delivering over 10,000 BTUs) weighs significantly less than a cast iron equivalent. This technical advantage means it is often possible to install the Oscar 1846 on internal stud walls or plasterboard partitions, provided you locate the timber studs for the brackets or use specialist heavy-duty hollow wall anchors, solving the problem of installing high-output heating in modern apartments with lightweight walls.
Why is it critical to use a specific type of corrosion inhibitor with the Oscar 1846mm Aluminium radiator?
Aluminium is chemically reactive to pH levels outside the neutral range (7.0 - 8.0). Standard inhibitors designed for steel radiators often allow the pH to rise too high (alkaline), which attacks the aluminium oxide layer. This causes electrolytic corrosion, generating hydrogen gas (air locks) and leading to pinhole leaks. To solve this, you must use a high-quality "mixed metal" inhibitor (like Fernox F1 or Sentinel X100) and check the system pH annually. Failure to do so is the primary cause of failure and will void the 10-year guarantee.
Does the Oscar 1846mm radiator require a flow diverter for correct operation and how is it installed?
Yes, for tall vertical radiators like the Oscar 1846mm, ensuring water reaches the top of the radiator is vital. If you connect the flow and return to the bottom connections (Bottom Opposite Ends), the water path can short-circuit across the bottom. A flow diverter (often a spring or baffle) must be inserted into the inlet side. This technical component forces the incoming hot water to travel up the first section to the top header rail, ensuring the entire 1.8-meter height heats up evenly and preventing the common problem of "cold spots" at the top of the unit.
What is the maximum operating pressure for the Oscar 1846mm radiator and is it suitable for commercial heating loops?
The Oscar 1846mm is manufactured from high-pressure extruded aluminium. It is technically rated for operating pressures much higher than standard domestic systems
Is the powder coat finish on the Oscar 1846mm durable enough for high-traffic areas like hallways?
The Oscar 1846mm is finished in a high-quality epoxy-polyester powder coat (Standard RAL 9010 White or optional colours). This finish is electrostatically applied and baked on, creating a hard, impact-resistant shell. It is technically superior to wet paint and resists chipping and scratching better than standard radiator enamel. However, given the radiator's projection into the room, care should still be taken in narrow hallways to avoid heavy impacts from furniture moving, as deep scratches exposing the aluminium can lead to surface oxidation.
Does the modular design mean I can add sections to the Oscar 1846mm radiator if my room is still cold?
While the Oscar 1846mm is constructed from modular 80mm sections joined by nipples and gaskets, extending it after installation is technically difficult and risky. It requires draining the system, removing the radiator, and using a specialized heavy-duty joining tool with new fibre gaskets. Breaking the factory seal often leads to leaks if not done perfectly. Therefore, the correct problem-solving approach is to use a BTU calculator to slightly oversize the radiator initially, rather than relying on the possibility of extending it later.
