Frequently Asked Questions
How does the tube-on-tube design of the Reina Cavo technically improve heat output compared to standard ladder rails?
The Reina Cavo features a distinctive tube-on-tube design where the horizontal bars are mounted on the front of the vertical collectors rather than between them. Technically, this configuration increases the surface area exposed to the room and allows for a higher volume of hot water to circulate through the rail. This solves the problem of low heat emission often found in standard flat ladders, ensuring the Cavo delivers a higher BTU output (up to 1757 BTUs for the 1580mm model) to warm both your towels and the bathroom air effectively.
Why is the stainless steel construction of the Reina Cavo recommended for wet room zones?
The Reina Cavo is manufactured from high-quality stainless steel, which naturally resists oxidation and corrosion without relying on a surface plating. This technically solves the issue of "peeling chrome" or rust spots that frequently occur on mild steel radiators in high-humidity zones like wet rooms or walk-in showers. The material forms a self-repairing passive layer, ensuring the rail maintains its structural integrity and aesthetic finish even when exposed to direct water splashes.
Can the Reina Cavo be installed on a Dual Fuel system for year-round towel drying?
Yes, the Reina Cavo is fully compatible with dual fuel installation. To solve the problem of unheated towels during the summer months when your main boiler is off, you can install a "T-Piece" connector on one of the bottom inlets. This allows you to insert an electric heating element into the vertical collector while keeping the central heating valves connected. You must ensure the element's wattage matches the liquid capacity of the specific Cavo model (e.g., approx 150W-300W depending on size) to prevent overheating.
What are the specific pipe center requirements for roughing-in plumbing for the Reina Cavo?
For accurate first-fix plumbing, you need to calculate the pipe centers based on the rail's width. The Reina Cavo has side connections at the bottom. The technical rule for pipe centers is approximately the Radiator Width minus 30mm (varies slightly by valve type). For the 500mm wide Cavo, the pipe centers would be roughly 470mm. The distance from the wall to the pipe centers is typically 65mm-80mm depending on the adjustable bracket setting. Always have the physical unit on-site before drilling tiles to solve misalignment issues.
Is the Reina Cavo compatible with open circuit (direct) hot water systems?
Unlike mild steel radiators which corrode if exposed to fresh oxygenated water, the stainless steel construction of the Reina Cavo makes it technically compatible with open or direct hot water systems. This solves the heating problem for homes that run their towel rails directly off the domestic hot water cylinder rather than a closed central heating loop, preventing the black sludge and leaks associated with using incompatible metals in open systems.
What type of valves are required to connect the Reina Cavo to standard piping without restricting flow?
The Reina Cavo uses standard 1/2 inch BSP female connections located at the bottom of the vertical collectors. To ensure proper flow dynamics, your valve selection depends on your pipework position. If pipes emerge from the wall, you technically require Angled Valves or Corner Valves to connect without stress on the joints. If pipes come up from the floor, Straight Valves are the correct choice. Using the wrong valve orientation can restrict water flow and cause system noise.
How do I bleed the Reina Cavo if the top horizontal bars remain cold?
Cold spots at the top of the rail indicate trapped air preventing hot water circulation. To fix this technical issue, turn off your central heating pump. Locate the air vent (bleed valve) at the top of the vertical collector. Use a radiator key to open the valve slightly until the air stops hissing and water begins to flow steadily. This displaces the air pocket with system water, restoring full thermal efficiency to the upper section of the rail.
Does the wall projection of the Reina Cavo allow for thick bath sheets to be hung easily?
The Reina Cavo has a wall depth of approximately 115mm. This generous projection, combined with the tube-on-tube design where bars sit forward of the uprights, technically solves the airflow problem seen in flatter rails. It creates ample clearance between the bars and the wall, allowing you to slide thick bath sheets behind the bars easily. This ensures better air circulation through the fabric for faster drying and prevents damp towels from touching the wall surface.
What does the 10 Year Guarantee technically cover regarding the Reina Cavo's welds and material?
The 10 Year Guarantee provided with the Reina Cavo covers technical manufacturing defects, specifically leaking welds and material failure under normal operating pressures. It verifies that the rail is manufactured to BS EN 442 standards and pressure tested (typically to 10 bar) to ensure safety in pressurized central heating systems. This guarantee solves the financial risk of premature failure, provided the system has been properly flushed and treated with a corrosion inhibitor upon installation.
