Frequently Asked Questions
How does the heat output of the Reina Marco Chrome compare to painted radiators of similar size?
The chrome plating process on the Reina Marco acts as a thermal insulator which technically reduces the heat emission rate by approximately 20 to 30 percent compared to white or anthracite powder-coated models. For example the 1100mm Reina Marco Chrome outputs 1428 BTUs. If you are installing this in a bathroom with poor insulation or large windows you must solve the potential heating deficit by either selecting the largest 1400mm model or ensuring you have a secondary heat source like underfloor heating to maintain a comfortable ambient temperature.
What specific components are required to convert the Reina Marco Chrome into a dual fuel system?
To convert the Reina Marco Chrome to dual fuel operation you technically need to install a T-piece at the inlet valve. This allows you to connect both the central heating water supply and an electric heating element simultaneously. You must select an element wattage that matches the specific output of the rail; for the 800mm model (307 Watts) a 150W element is suitable while the 1400mm model (495 Watts) requires a 300W element to prevent overheating the fluid inside the rail when the central heating is off.
How does the 120mm depth of the Reina Marco Chrome affect installation in narrow bathrooms?
The Reina Marco features a projection of 120mm from the wall to the front face which is deeper than many standard ladder rails. In a narrow cloakroom or en-suite this depth can technically obstruct door swings or reduce walkway width. To solve this spatial problem you must measure the clearance radius of your bathroom door and ensuring there is at least 150mm of clearance space in front of the radiator to allow for safe movement and the hanging of thick towels without blockage.
What are the correct pipe center measurements for the Reina Marco given its 500mm width?
The pipe centers for the Reina Marco are not exactly 500mm. Technically the centers are calculated based on the width of the vertical collectors minus or plus the valve variance. For this ladder rail the pipe centers will be approximately 455mm to 460mm depending on your specific valve choice. You must physically measure the radiator with the valves attached before drilling holes in your floor tiles to avoid the costly problem of misaligned pipes which places stress on the valve seals.
Why might the top bars of the Reina Marco Chrome remain cold after installation?
Cold spots at the very top of vertical ladder rails like the Reina Marco are almost always caused by trapped air pockets that prevent hot water from circulating to the highest point. To fix this technical issue turn off your central heating pump to stop the flow and locate the bleed valve at the top of the vertical upright. Use a radiator key to open the valve slightly until the hissing air stops and water begins to flow. Close it tightly to restore full internal pressure.
What type of radiator valves should I use if my pipes emerge from the wall?
The inlet connections on the Reina Marco Chrome are located at the bottom of the vertical uprights. If your central heating pipes come out of the wall you should technically use Angled or Corner radiator valves to create the necessary 90 degree turn into the bottom of the rail. Using straight valves in this scenario would force the pipes to protrude awkwardly into the room. Corner valves provide the neatest solution keeping the valve heads tucked in line with the radiator for a streamlined professional finish.
How do I maintain the chrome finish on the Reina Marco to ensure the 10 Year Guarantee remains valid?
The 10 Year Guarantee covers manufacturing defects but can be voided by improper maintenance that damages the plating. To solve the problem of corrosion or peeling chrome you must never use abrasive scouring pads or acidic cleaning agents containing bleach. You should clean the rail using only a soft microfiber cloth and warm soapy water. Additionally you must ensure the bathroom is well ventilated to prevent condensation from sitting on the cool metal surface when the heating is off which can lead to surface pitting over time.
Is the Reina Marco Chrome compatible with low temperature heat pump systems?
The listed heat outputs (e.g. 1732 BTUs for the 1400mm model) are calculated at Delta T50 which assumes a boiler flow temperature of around 75 degrees Celsius. If you are using a renewable heat pump system that operates at lower temperatures (Delta T30) the actual output will be significantly lower likely around 850 BTUs. To solve this sizing problem you must apply a correction factor to the manufacturer's rating and likely install the largest available model to provide sufficient heat.
Can the Reina Marco Chrome be installed on a plasterboard partition wall safely?
The Reina Marco is constructed from mild steel and holds a significant volume of water especially the 1400mm model making it heavy. Installing this directly into plasterboard using standard wall plugs creates a risk of the fixings pulling out under the cantilevered load. To solve this structural issue you must locate the timber studs behind the plasterboard or install a timber noggin between the studs prior to tiling. The brackets should be screwed directly into this timber reinforcement to guarantee a safe and secure installation.
Does the Reina Marco require a specific water treatment to prevent internal corrosion?
Yes like all mild steel radiators the Reina Marco is susceptible to internal rust if the heating system water is not treated. To solve this maintenance issue you must add a high quality chemical inhibitor to your central heating loop during installation. This chemical coats the inside of the steel tubes preventing reaction with oxygen in the water. Failure to do so will lead to the formation of black magnetite sludge which blocks the waterways and eventually causes pinhole leaks that are not covered by the warranty.
