Frequently Asked Questions
How does the solid cast iron panel design between the columns of the Edwardian 2 450mm radiator technically enhance thermal efficiency?
Unlike standard open-column radiators, the Beaumont Edwardian 2 features unique solid cast iron webs or panels between the two vertical columns. This technical design feature significantly increases the surface area and thermal mass of the radiator. By "amplifying" the heat retention, these solid sections allow the radiator to store more thermal energy and radiate warmth for a longer period after the boiler cycles off, making it a highly economical choice for maintaining steady room temperatures.
What are the specific dimension constraints for installing the Edwardian 2 450mm radiator in narrow hallways or corridors?
The Edwardian 2 450mm is engineered with a slimline profile, having a section depth of just 108mm (measured from the skirting board). This is significantly shallower than many traditional cast iron models (often 140mm+). When you add the required wall stay clearance (approx 20mm), the total projection is roughly 130mm. This technical compactness makes it the ideal problem-solving solution for heating narrow hallways or landings where preserving clear walkway width is critical.
How do I calculate the total heat output for a custom-sized Edwardian 2 450mm assembly?
The heat output is modular. Although exact BTU ratings can vary slightly by system temperature, a standard calculation uses the Delta T50 rating per section. For the Edwardian 2 450mm, you generally assume approximately 140-150 BTUs per section (due to its compact height). To solve your room's heating requirement, divide your total heat loss (e.g., 2000 BTUs) by 145. This determines the precise number of sections (e.g., 14 sections) needed to heat the space efficiently without oversizing.
What are the floor loading specifications given the 3kg per section weight of the Edwardian 2 450mm model?
While lighter than larger models, the Edwardian 2 450mm still has a high density. Each section weighs approximately 3kg. A 15-section radiator would weigh 45kg empty and roughly 55kg when filled with water. Technically, you must ensure your floorboards or subfloor can support this static load. For suspended timber floors, it is best practice to locate the radiator feet directly above the joists or install additional timber noggins to prevent long-term deflection of the floorboards.
Why is the 450mm height of the Edwardian 2 specifically suited for combating window downdraughts?
The 450mm height is a strategic technical dimension designed to fit beneath standard and low-level window sills. Placing a radiator here is the most efficient way to heat a room, as the rising warm air convection current meets the cold air falling from the window glass (downdraught). This interaction neutralizes the cold draft and circulates warm air into the room, solving the problem of "cold spots" near glazing without obstructing the view or curtain drape.
What are the technical requirements for painting the "Primed" finish of the Edwardian 2 450mm radiator?
The radiator is supplied in a base Primer which is a protective transit coat, not a final finish. The cast iron surface is porous; if left in just primer, it will absorb moisture and rust. You must technically apply a suitable topcoat (oil-based eggshell, satin, or specialist radiator enamel) to seal the metal. Ensure the radiator is cold, clean, and dry before painting. Alternatively, specifying a factory-applied "Farrow & Ball" or "RAL" finish provides an immediate, professionally cured protective layer.
Are the 1/2 inch BSP connections on the Edwardian 2 450mm compatible with standard thermostatic valves?
Yes, the Edwardian 2 450mm features industry-standard 1/2 inch BSP female connections at the bottom. This ensures full technical compatibility with all modern manual and Thermostatic Radiator Valves (TRVs). Due to the radiator's "Edwardian" period styling, it is aesthetically recommended to use traditional-style brass or black nickel valves (like the Bentley or Crocus range) which complement the cast iron aesthetic while providing modern energy-saving control.
Why is a "Luxury Wall Stay" mandatory for the installation of the Edwardian 2 450mm radiator?
Even though the Edwardian 2 is lower (450mm) and less top-heavy than taller models, it is a freestanding heavy object. A Wall Stay is technically required to anchor the radiator to the wall and prevent it from tipping over if knocked or pulled (e.g., by a child). A "Luxury" stay clamps firmly to the rear column and provides a rigid mechanical brace, ensuring the installation complies with safety standards without bearing the vertical weight of the radiator.
What specific water treatment is required to protect the Edwardian 2 450mm cast iron radiator from internal corrosion?
Cast iron is susceptible to oxidation if the system water is not treated. Technically, you must flush the system thoroughly upon installation to remove flux and debris. Then, you must fill the system with water dosed with a high-quality Corrosion Inhibitor (suitable for mixed-metal systems) and check that the pH is neutral (between 7.0 and 8.0). Failure to maintain this chemical balance can lead to sludge build-up and internal corrosion, which will void the 10-year manufacturer guarantee.
