Frequently Asked Questions
What is the exact heat output per section for the Saxon 1446mm Vertical model to assist with precise room sizing?
The Saxon 1446mm Vertical radiator is engineered to deliver high thermal performance. Each individual section generates approximately 836 BTUs (245 Watts) at Delta T50. To solve your sizing calculation, simply divide your room's total heat loss requirement by 836. For example, a 5-section model (only 420mm wide) delivers 4180 BTUs. This high output density allows you to heat significant spaces using a very narrow vertical footprint, maximizing usable wall area for furniture.
Why is the Saxon 1446mm Aluminium radiator technically recommended for use with Air Source Heat Pumps (ASHP)?
The Saxon 1446mm combines a large vertical surface area with the high thermal conductivity of aluminium. In low-temperature systems like ASHPs (running at 35-45
Do I need to install a flow diverter or baffle in the Saxon 1446mm Vertical radiator?
Yes, for vertical aluminium radiators like the Saxon 1446mm, correct internal water flow is critical. If you pipe the radiator with flow and return at the bottom (Bottom Opposite Ends), the water may short-circuit across the bottom rail. To solve this, a flow diverter (spring or baffle) is typically required in the inlet. This component forces the hot water to travel vertically up the first section to the top header, ensuring the entire 1.4-meter height heats up evenly and preventing cold spots at the top.
What are the depth and total projection specifications for the Saxon 1446mm Vertical radiator?
The Saxon 1446mm sections have a depth of 95mm. When calculating the installation footprint, you must technically account for the wall brackets. The total projection from the wall to the front face of the radiator will generally be between 120mm and 130mm. While this is slim for a high-output vertical unit, you should check this dimension against door swings or hallway widths to ensure the radiator does not become an obstruction.
Is the Saxon 1446mm Vertical radiator suitable for mounting on internal stud or plasterboard walls?
One of the primary technical advantages of the Saxon Aluminium range is its low weight. A 1446mm high steel or cast iron radiator would be extremely heavy and require masonry walls. The Saxon is significantly lighter, making it technically feasible to install on internal stud walls. You should secure the brackets directly into the timber studs or use high-load toggle fixings, solving the problem of retrofitting high-output vertical heating in modern homes with lightweight partition walls.
What specific corrosion inhibitor must be used with the Saxon 1446mm to protect the 10 Year Guarantee?
Aluminium is chemically sensitive to pH levels. You must use a high-quality "mixed metal" corrosion inhibitor (such as Fernox F1 or Sentinel X100) and maintain a system water pH between 7.0 and 8.0. Standard steel inhibitors can cause the pH to rise (become alkaline), which eats away the aluminium oxide layer and causes hydrogen gas build-up. Failure to maintain this specific chemical balance will cause pinhole leaks and voids the manufacturer's guarantee.
Are the finishes on the Saxon 1446mm radiator durable enough for high-humidity environments like bathrooms?
The Saxon 1446mm comes in a standard White RAL 9010 powder coat, with optional custom RAL colours. This finish is electrostatically applied and baked at high temperatures to create a sealed, non-porous surface. This makes it technically resistant to humidity and suitable for bathrooms or kitchens. However, if the paint surface is deeply scratched or chipped, the exposed aluminium can oxidize. Immediate touch-up of any damage is required to maintain this protection in wet areas.
How does the low water content of the Saxon 1446mm radiator improve the overall energy efficiency of the heating system?
The Saxon 1446mm holds a fraction of the water volume of a steel panel or cast iron radiator of the same output. This low thermal mass means the boiler or heat pump has less water to heat up, resulting in a much faster response time. The radiator reaches operating temperature in minutes, providing immediate comfort. Conversely, it cools down quickly when the thermostat turns off, preventing the energy waste of "overshoot" heating, which directly reduces fuel consumption.
Can the Saxon 1446mm Vertical radiator be connected to a high-pressure district heating system?
The Saxon range is manufactured using high-pressure aluminium die-casting or extrusion techniques. It is typically rated for operating pressures of 10 Bar or higher (always check the specific batch rating). This makes it technically robust enough for high-pressure communal or district heating systems often found in modern apartment blocks, where standard steel panel radiators (often rated to only 6 Bar) would be unsuitable or prone to failure.
