Frequently Asked Questions
What is the practical advantage of choosing a Reina Diva Curved Towel Rail over a flat model?
The primary technical benefit of the Reina Diva Curved Towel Rail is the increased space behind the horizontal bars. The gentle curve projects the mid section of the rail further into the room compared to the vertical collectors. This creates a larger gap between the bars and the wall, making it significantly easier to slide thick bath towels through for drying. Additionally, the curved profile increases the total surface area slightly compared to a flat rail of the same width, potentially offering a marginal increase in convective heat output.
How do I calculate the total wall projection for the Reina Diva Curved model during installation?
The product specifications list the depth of the Reina Diva Curved Towel Rail as typically between 85mm and 100mm, depending on the adjustment of the wall brackets. Unlike flat rails which have a consistent depth, the curve means the center of the rail sits further out than the sides. When planning your installation, particularly behind a door, you must measure for the maximum projection at the center point of the curve to ensuring the door does not hit the radiator when fully open.
Can the Reina Diva Curved Towel Rail be converted for Dual Fuel operation?
Yes, the Reina Diva Curved range is technically suitable for Dual Fuel conversion. This involves installing a T piece and an electric heating element alongside the standard radiator valves. This setup allows you to heat the rail via your central heating in winter and use the electric element in summer when the main boiler is off. You must ensure the electric element rating (in Watts) is compatible with the towel rail's fluid capacity to prevent overheating or inefficient warming.
What type of valves are required for connecting this towel rail to standard pipework?
The Reina Diva Curved Towel Rail has standard 1/2 inch BSP connections located at the bottom of the vertical collectors. If your central heating pipes come up from the floor, you will technically require Angled Radiator Valves. If your pipes come straight out of the wall, you can use either Angled valves (which will turn the head outwards) or Corner valves (which keep the head in line with the rail) for a neater finish. Straight valves are generally only used if pipes run along the wall surface.
How does the Chrome finish affect the heat output of the Reina Diva Towel Rail?
It is a technical fact that Chrome finishes have a lower emissivity rating compared to painted finishes like white or anthracite. This means a Chrome Reina Diva Curved rail will output approximately 20 to 30 percent less heat (BTUs) than a painted version of the exact same size. When sizing this radiator for your bathroom, you must factor this into your heat loss calculations to ensure the Chrome model provides sufficient warmth to heat the room, not just dry towels.
Is it possible to install this towel rail as a standalone Electric Only unit?
Absolutely, the Reina Diva Curved Towel Rail can be installed as an Electric Only unit if you do not have central heating pipes in the bathroom. To do this technically, you would not install valves. Instead, you fill the rail with a thermodynamic fluid (usually a water and glycol mixture for frost protection and corrosion inhibition) and insert an electric heating element. You must leave a small expansion gap (air gap) at the top to accommodate internal pressure changes as the fluid heats up.
What does the 10 Year Guarantee cover regarding the Mild Steel construction?
The 10 Year Guarantee provided with the Reina Diva Curved range covers manufacturing defects related to the Mild Steel construction and the welding integrity. This protects you against leaks caused by faulty welds or material failure. It also covers the quality of the Chrome plating against peeling or flaking under normal conditions. However, it is vital to note that the guarantee is valid only if the heating system contains the correct corrosion inhibitor to protect the steel from internal rust.
How do I determine the correct pipe centers for roughing in pipework before tiling?
For standard ladder rails like the Reina Diva Curved, the pipe centers are typically the total width of the rail minus approximately 50mm. For example, if you purchase the 600mm wide model, the pipe centers will be roughly 550mm apart. However, because manufacturing tolerances can vary slightly, it is technically best practice to have the physical product on site before drilling tiles or fixing pipework positions to avoid costly adjustments later.
Why is the 25mm tube diameter significant for the Reina Diva range?
The Reina Diva Curved Towel Rail features horizontal tubes with a 25mm diameter. This is a technical specification that indicates a robust build quality compared to cheaper models which often use thinner 19mm or 22mm tubes. The larger 25mm diameter increases the surface area for heat emission and allows for a greater volume of hot water to flow through the rail, resulting in better performance and a sturdier, more substantial look and feel.
What is the difference in heat output between the 800mm and 1800mm high models?
The heat output is directly proportional to the number of horizontal bars (sections) and the total surface area. The 800mm high model typically has around 14 sections and outputs roughly 668 BTUs. In contrast, the 1800mm high model has 31 sections and outputs around 2487 BTUs. Technically, this means the taller model is nearly four times more powerful, making it suitable as a primary heat source for a family bathroom, whereas the smaller model is designed strictly for towel warming in small ensuites.
