Frequently Asked Questions
How does the Delta T 50 rating of the Ashby affect my bathroom heating calculations?
The heat output of the Ashby, such as the 2557 BTUs for the large model, is rated at Delta T 50. This assumes your central heating water is 75
What is the difference between the standard RAL 9016 finish and the S4H Special Finish options?
The standard RAL 9016 is a specific Traffic White powder coating that offers a bright, neutral finish with high durability against humidity. The S4H Special Finish and S4H RAL Colour options allow for technical customization, offering different textures or specific color codes to match your bathroom interior. While the standard finish is immediately available, special finishes involve a bespoke manufacturing process that provides the same corrosion resistance but allows you to solve specific aesthetic design requirements.
How do I calculate the total wall projection for the Ashby given its 72mm depth specification?
The 72mm depth specification refers strictly to the thickness of the Ashby ladder rail itself. To solve the installation layout, you must add the depth of the wall brackets. Standard brackets typically add 70mm to 90mm of clearance. Therefore, the total projection into the room will likely be between 140mm and 160mm. You must account for this total distance when measuring clearance behind opening doors or near sanitaryware to prevent obstruction.
Can the Ashby Designer Ladder Rail be converted to a dual fuel system for summer use?
Yes, the Ashby can be converted into a dual fuel towel rail. This technical modification involves installing an electric heating element and a T-piece fitting into one of the bottom inlets. This allows you to heat the rail electrically when the central heating is off in summer. You must ensure the selected element wattage (e.g., 300W or 600W) is compatible with the fluid volume of the specific Ashby model size you choose to prevent pressure buildup or boiling.
Why does the Ashby use a vertical column design instead of standard D profile tubes?
The Ashby utilizes a robust vertical column construction to solve the problem of low heat output often found in standard ladder rails. The larger diameter and surface area of the vertical columns allow for a greater volume of hot water to flow through the rail. This technical design choice increases the radiant heat emitted into the room, ensuring the unit functions as an effective radiator for the air temperature, not just a warmer for towels.
What type of radiator valves are required for the installation of the Ashby Towel Rail?
The Ashby requires standard 15mm radiator valves. The choice between Angled, Straight, or Corner valves depends on your pipework position. If your pipes emerge from the wall, Angled or Corner valves are the correct technical solution to keep the head of the valve tidy. If pipes come from the floor, Straight valves are needed. You must ensure the valve thread matches the standard 1/2 inch BSP tapping found on the bottom of the Ashby vertical collectors.
Is the 10 Year Guarantee valid if the Ashby is installed on an open vented heating system?
The 10 Year Guarantee covers manufacturing defects and corrosion resistance, but it is technically contingent on the water quality of your heating system. Whether you have an open vented or sealed system, you must ensure the system is chemically treated with a high-quality inhibitor to prevent internal oxidation and sludge. Installing the Ashby on a system with untreated water or active corrosion issues may void the warranty if the failure is caused by internal water chemistry rather than a product fault.
How does the weight of the Ashby influence the choice of wall fixings for plasterboard walls?
Although the Ashby weighs between 7kg and 13kg when empty, its weight increases significantly when filled with water. A standard plasterboard fixing may not hold this dynamic load, especially when towels are added. The technical solution is to anchor the brackets directly into the timber studs behind the plasterboard. If studs do not align with the rail width (500mm or 600mm), you should install a horizontal timber noggin within the wall or use specialist heavy-duty toggle fixings to distribute the load safely.
What is the significance of the tube spacing on the Ashby regarding towel drying efficiency?
The Ashby features sections of horizontal bars (9, 12, or 15 bars) with specific gaps between them. This spacing is a technical feature designed to allow adequate air circulation between layers of towels. Tightly packed bars can trap moisture, leading to damp smells. The optimized spacing on the Ashby ensures that warm air rises through the gaps, creating a convection current that dries towels faster and heats the bathroom air more efficiently.
How do I maintain the powder coated finish of the Ashby to prevent surface damage over time?
To maintain the RAL 9016 or special finish, you should avoid using abrasive chemical cleaners or scouring pads, as these can create micro-scratches that allow moisture to penetrate the coating. The correct technical maintenance involves wiping the rail with a soft cloth and warm soapy water only when the radiator is cold. Cleaning a hot radiator can cause the cleaning solution to evaporate too quickly, leaving streaky residues that are difficult to remove without damaging the paint.
