Frequently Asked Questions
How does the 1646mm height of the Oscar Aluminium Radiator maximize thermal efficiency in rooms with limited floor space?
The Oscar 1646mm High model is technically engineered to solve the problem of heating large rooms where wall width is restricted, such as narrow hallways or kitchen pillars. By utilizing vertical height rather than horizontal width, it provides a massive surface area for heat exchange. The 1646mm columns create a powerful "chimney effect," drawing cool air from the floor, heating it rapidly as it rises through the long flutes, and projecting it out at the top, ensuring effective convection heating throughout the room volume without occupying valuable furniture space.
What are the precise BTU and Wattage outputs per section for the Oscar 1646mm model and how does this affect sizing?
Each individual section of the Oscar 1646mm radiator delivers approximately 925 BTUs (271 Watts) at Delta T50. This is a very high output for a single vertical strip. To solve your sizing requirements, you simply divide your room's total heat loss figure by 925. For example, a 10-section unit (total width 820mm) produces a massive 9247 BTUs. This high density of heat output allows you to heat very large open-plan areas with a single, relatively compact vertical unit, reducing the need for multiple radiators.
What are the depth and projection specifications for the Oscar 1646mm radiator when installing in a narrow corridor?
The Oscar 1646mm radiator has a section depth of 116mm. However, for installation planning, you must account for the wall brackets. The total projection from the wall to the front face of the radiator will be approximately 146mm depending on the bracket adjustment. While this is deeper than a standard flat panel, the rounded column design minimizes sharp edges, making it a safe and practical option for high-traffic areas like corridors or landings where people might brush past.
Is the Oscar 1646mm Aluminium radiator compatible with low temperature heating systems such as air source heat pumps?
Yes, the Oscar 1646mm is an excellent technical choice for renewable heating systems. Aluminium has a thermal conductivity 5 times greater than steel, allowing it to respond instantly to the lower water temperatures (35-45
What specific type of corrosion inhibitor must be used with the Oscar 1646mm to prevent hydrogen gas build up?
Because the Oscar 1646mm is made from aluminium, it is chemically sensitive to pH levels. You must use a high quality central heating inhibitor specifically formulated for "mixed metal" systems (containing aluminium, copper, and steel). You must maintain the system water pH between 7.0 and 8.0. Failure to do this can lead to electrolytic corrosion, which generates hydrogen gas (requiring frequent bleeding) and can eventually cause pinhole leaks, voiding the 10 year manufacturer guarantee.
Can the Oscar 1646mm radiator be installed on internal stud walls despite its large size and heat output?
One of the main problem solving features of the Oscar 1646mm is its lightweight construction. A cast iron radiator of this height would weigh hundreds of kilograms and require solid masonry or floor reinforcement. The Oscar is made from extruded aluminium, making it significantly lighter. A 5-section model (producing over 4600 BTUs) is light enough to be hung on a standard internal stud wall using appropriate fixings into the timber uprights, simplifying installation in modern homes or apartments.
Why is the Oscar 1646mm radiator supplied with a diverter or baffle and how must it be installed?
Tall vertical radiators like the Oscar 1646mm can suffer from flow circulation issues if not piped correctly. If you connect the flow and return pipes to the bottom of the radiator (Bottom Opposite Ends), the water may naturally flow across the bottom without rising to the top. To solve this, a flow diverter or baffle (often a spring or internal plug) is usually required inside the inlet to force the water up the first section to the top header. You must ensure your plumber installs this correctly to guarantee the entire 1.6 metre height heats up evenly.
Does the modular sectional design allow me to extend the width of the Oscar 1646mm radiator after purchase?
While the Oscar 1646mm is built from individual 80mm sections joined by nipples and gaskets, it is technically advised to order the correct size from the factory. Extending the width on-site requires a specific high-torque joining tool and fresh fibre gaskets to ensure a pressure-tight seal. Opening the radiator can compromise the factory seal. Therefore, it is best to use a BTU calculator to determine the exact number of sections needed beforehand rather than attempting to modify the unit later.
How durable is the finish on the Oscar 1646mm radiator against scratches and moisture in a bathroom environment?
The Oscar 1646mm features a high quality polyester powder coat finish (Standard RAL 9010 or custom colours). This finish is baked on at high temperatures to create a hard, non-porous shell that is highly resistant to scratches and impact. This sealed surface makes it technically suitable for humid environments like bathrooms, as it prevents moisture from reaching the aluminium substrate. However, if the paint is deeply chipped, it should be touched up immediately to prevent oxidation of the exposed metal.
What is the maximum operating pressure for the Oscar 1646mm and is it suitable for high rise apartment blocks?
The Oscar 1646mm is manufactured using an extrusion process that creates a seamless vertical column. This construction method allows it to withstand significantly higher pressures than standard panel radiators, often rated up to 16 Bar (test pressure usually higher). This technical specification makes it perfectly suitable for high pressure district heating systems found in high rise apartment blocks or commercial buildings, where standard residential radiators might fail or leak.
