Frequently Asked Questions
How does the cantilevered shelf design impact the installation and wall spacing requirements?
The Reina Troisi features a unique cantilevered design with a prominent top shelf that extends significantly from the wall. The total depth or wall projection is 300mm, which is much deeper than standard flat ladder rails. When planning your installation, you must technically account for this 300mm projection to ensure the unit does not obstruct door swings, shower enclosures, or walkways. This deep profile is intentional to provide a functional heated shelf for stacking folded towels while leaving the lower bar free for hanging active towels.
What are the precise pipe centre measurements required for first fix plumbing?
To install the Reina Troisi correctly, you need to set your pipework to the specific pipe centre dimension of 462mm. This measurement is the distance between the centres of the two water inlet/outlet pipes. Since the overall width of the unit is 532mm, the pipe connections are inset. Additionally, the Wall to Pipe Centre distance is fixed at approximately 67mm. It is critical to adhere to these dimensions during the first fix stage to avoid the need for offset elbows or adjusting tiled surfaces later.
Can the Reina Troisi be converted to a dual fuel unit for summer use?
Yes, the Reina Troisi is compatible with dual fuel conversion, allowing you to use it with your central heating in winter and as an electric towel warmer in summer. To achieve this, you must install a T-piece on one of the inlet valves to accommodate both the water flow and an electric heating element. You must select an element with a wattage that matches the liquid capacity of the rail (typically around 100W to 150W for this size) to prevent overheating. This setup ensures you have warm dry towels year round without running the main boiler.
Is the heat output of 708 BTUs sufficient to heat my entire bathroom?
The Reina Troisi delivers a heat output of approximately 708 BTUs (Delta T50). While this is excellent for warming towels and providing background heat, it may not be sufficient as the primary heat source for large or poorly insulated bathrooms. You should calculate your room's specific BTU requirement by measuring the Height, Length, and Width in meters and multiplying the volume by 150. If your room requires more than 700 BTUs, you should technically treat the Troisi as a supplementary towel warmer and install it alongside a second radiator or underfloor heating.
What type of radiator valves are compatible with the Reina Troisi connection ports?
The Reina Troisi is equipped with standard 1/2 inch BSP female connections located on the vertical uprights. For a standard installation where your pipes emerge from the wall, you should technically use Corner Valves or Angled Valves turned 90 degrees to achieve a neat finish. If your pipes come up from the floor, Angled Valves are the correct choice. Straight valves are generally not suitable unless you are running surface mounted pipework horizontally along the wall to meet the rail connections.
How do I maintain the polished surface to ensure the 25 Year Guarantee remains valid?
The Reina Troisi comes with a market leading 25 Year Guarantee, which reflects the durability of the stainless steel. To maintain this warranty and the aesthetic appeal, you must clean the surface regularly using only a soft cloth and warm soapy water. You must strictly avoid using abrasive scouring pads, steel wool, or chlorine based cleaning agents (like bleach), as these can chemically attack the passive oxide layer of the stainless steel, leading to surface pitting or scratching that is not covered by the manufacturing defect warranty.
Does the shelf configuration affect the bleeding process for removing trapped air?
Yes, the horizontal shelf configuration can trap air if the system is not bled correctly. The air vent (bleed valve) is typically located at the highest point of the vertical upright. If you notice the top shelf bars are cold while the bottom section is hot, you have an air lock. To solve this, turn off the central heating pump, wait for the system to settle, and carefully open the bleed screw with a radiator key until a steady stream of water flows without sputtering. This ensures the hot water circulates through the entire shelf loop.
Is the Reina Troisi compatible with open vented central heating systems?
Yes, the Grade 304 Stainless Steel construction makes the Reina Troisi chemically inert and fully compatible with both modern sealed pressurized systems and traditional open vented (gravity fed) systems. Unlike aluminium radiators which can suffer from electrolytic corrosion in open systems, stainless steel does not react with copper pipework or oxygenated water. This makes it a technically safe and versatile choice for any domestic heating system architecture without requiring special inhibitors beyond standard maintenance.
Why are the wall brackets non adjustable and how does this affect mounting on uneven walls?
The Reina Troisi is supplied with fixed stainless steel wall brackets to support the leverage weight of the 300mm deep shelf. Because the brackets are not adjustable, the mounting wall must be perfectly flat and vertical. If you are installing on an uneven surface or textured tiles, you may need to use packing washers behind the bracket base plates to ensure the rail sits level. Installing the unit on a twisted plane can cause stress on the stainless steel welds and make the pipe connections difficult to align without leaks.
