Frequently Asked Questions
How does the unique flat top design of the Gatsby 570mm radiator differ from traditional rounded cast iron models
The Gatsby 570mm features a distinctive flat top surface rather than the rounded shoulders found on Victorian or Georgian styles. This technical design characteristic, often referred to as the Urban or Art Deco style, provides a cleaner, more modern geometric profile. It effectively bridges the gap between period properties and contemporary industrial interiors, offering a shelf like appearance that prevents dust from settling in deep crevices found on curved models.
What is the exact heat output per section for the Gatsby 570mm radiator and how does this impact room sizing
Each individual section of the Gatsby 570mm radiator delivers approximately 310 BTUs or 91 Watts at Delta T50. To accurately size your radiator, you must divide the total heat loss requirement of your room by 310. For example, a living room requiring 4500 BTUs would technically need a 15 section assembly. This high output per section is due to the dense, boxy profile which maximizes the radiant surface area within a compact height.
Does the 180mm depth of the Gatsby 570mm radiator require specific consideration for wall projection
Yes, the Gatsby 570mm has a substantial section depth of 180mm. When you factor in the mandatory wall stay clearance of approximately 20mm to 30mm, the total projection from the wall into the room will be around 200mm to 210mm. You must technically assess your floor plan to ensure this deep profile does not obstruct walkways, door swings, or furniture placement, particularly in narrow hallways or small cloakrooms.
What are the structural floor load requirements for the heavy Gatsby 570mm radiator
The Gatsby 570mm is an exceptionally heavy radiator due to its solid, blocky casting. Each section weighs approximately 8.6 kg. A standard 10 section assembly weighs 86 kg empty and over 100 kg when filled with water. Technically, you must ensure that your subfloor can support this concentrated point load. For suspended timber floors, it is critical to position the feet directly over joists or install timber noggins bracing underneath to prevent floor deflection.
Why is the Gatsby 570mm supplied in a Primer finish and what are the painting obligations
The radiator is supplied in a standard Black or White Primer, which is a temporary protective coating to prevent rust during transit. It is not a sealed cosmetic finish. Technically, the installer must apply a final topcoat using an oil based eggshell or specialist radiator paint to seal the cast iron against moisture and oxidation. Failure to apply this topcoat will eventually lead to surface rust. Alternatively, factory applied polished or metallic finishes are available for immediate installation.
Do I need a Cast Iron Radiator Joining Tool for the Gatsby 570mm radiator
If you order a radiator longer than approximately 1200mm or 15 sections, it may be shipped in smaller blocks for safe handling. To assemble these blocks on site, you require a Cast Iron Radiator Joining Tool and a set of joining nipples. This technical process involves inserting the tool through the center of the radiator to screw the nipples into the internal threads, applying high torque to compress the gaskets and create a permanent watertight seal.
Are the connection tappings on the Gatsby 570mm compatible with modern thermostatic valves
The Gatsby 570mm is cast with standard 1/2 inch BSP female tappings at the bottom corners. This ensures full technical compatibility with all standard UK radiator valves, including modern Thermostatic Radiator Valves or TRVs. You do not need reducers. Due to the modern industrial aesthetic of the Gatsby, it pairs particularly well with geometric or simple valve designs in finishes like Pewter or Brushed Nickel rather than ornate floral valves.
What type of wall stay is required to stabilize the Gatsby 570mm radiator
Despite its wide and stable footprint, the Gatsby 570mm is a heavy freestanding object. A Luxury Wall Stay is technically mandatory to anchor the top of the radiator to the wall. This prevents the unit from tipping forward if accidentally impacted. Given the flat surfaces of the Gatsby sections, the wall stay must be carefully positioned between the sections to clamp securely against the rear column without scratching the finish.
Why is a system flush technically critical before commissioning the Gatsby 570mm radiator
Cast iron radiators are manufactured using sand moulds. Small amounts of casting sand or metal filings can remain inside the sections. Technically, it is vital to thoroughly flush the radiator and the heating pipework before final commissioning. If this debris is not removed, it can circulate into the boiler and damage the pump or heat exchanger. Installing a magnetic system filter is the recommended technical solution to trap ferrous debris and protect the system.
How does the high thermal mass of the Gatsby 570mm radiator affect heating schedules
The Gatsby 570mm has a very high thermal mass due to its weight and water content. This results in a slow heat up and cool down cycle known as thermal lag. Technically, you should program your heating to turn on 45 to 60 minutes before the room is occupied. Conversely, the radiator will act as a heat store, emitting warmth for over an hour after the boiler switches off. This helps maintain a stable, comfortable temperature in older properties with high heat loss.
