Frequently Asked Questions
How does the 660mm height of the Edwardian 2 radiator affect its heat output compared to the 450mm model?
The 660mm height provides a larger vertical surface area for heat exchange. Technically, each section of the 660mm model generates approximately 398 BTUs (116 Watts) at Delta T50, which is more than double the output of the shorter 450mm version. This increased thermal capacity makes the 660mm model highly effective for heating larger rooms with standard ceiling heights while occupying the same floor footprint width-wise.
What are the floor load considerations for the Edwardian 2 660mm radiator given its weight?
The Edwardian 2 660mm is a heavy-duty cast iron unit. A single section weighs approximately 7kg. A typical 10-section assembly weighs roughly 70kg empty and over 85kg when filled with water. You must technically verify that your floor structure (joists or concrete) can support this concentrated load. For suspended timber floors, placing the feet directly over joists or adding structural reinforcement (noggins) is mandatory to prevent floor deflection.
Does the 140mm depth of the Edwardian 2 660mm radiator require special planning for wall stays?
Yes, the 140mm section depth is substantial. When installing, you must account for the wall stay clearance (typically 20-30mm), creating a total projection of around 160-170mm from the wall. This depth requires the use of a Luxury Wall Stay (a rigid brass or chrome arm) to clamp the radiator securely to the wall. The wall stay prevents the tall, heavy unit from tipping forward, which is a critical safety requirement.
Are the 1/2 inch BSP connections on the Edwardian 2 660mm compatible with modern thermostatic valves?
The Edwardian 2 660mm features standard 1/2 inch BSP female connections at the bottom corners. This ensures full technical compatibility with all modern manual and Thermostatic Radiator Valves (TRVs). No reducers are needed. However, due to the traditional styling, it is aesthetically recommended to use "period-style" heavy-pattern valves (in brass or black nickel) that visually balance the substantial weight and design of the cast iron sections.
Why is a system flush technically critical before commissioning the Edwardian 2 660mm radiator?
Cast iron radiators are sand-cast. Microscopic residues of casting sand or iron filings can sometimes remain inside the sections. Technically, it is vital to thoroughly flush the radiator and the heating circuit before final commissioning. If this debris circulates, it can damage boiler pumps or block heat exchangers. Installing a magnetic system filter is highly recommended to trap any ferrous debris and protect the boiler warranty.
How does the high thermal mass of the Edwardian 2 660mm radiator influence the heating schedule?
The Edwardian 2 660mm has a high thermal mass due to its weight and water volume. This results in a slow heat-up and cool-down cycle (high thermal lag). Technically, you should program your heating to turn on 45-60 minutes before the room is occupied. Conversely, the radiator will effectively heat the room for an hour after the boiler switches off. This "flywheel effect" provides a stable, consistent temperature, ideal for older properties with high heat loss.
Is the Edwardian 2 660mm radiator suitable for low-temperature heating systems like heat pumps?
Yes, cast iron radiators like the Edwardian 2 660mm are technically well-suited for heat pumps. Although heat pumps operate at lower water temperatures (35-45
