Frequently Asked Questions
How does the double column design of the Reina Casina Aluminium Radiator specifically affect thermal output compared to a single panel model?
The double column (or double panel) configuration technically doubles the surface area available for heat transfer. By having a second layer of aluminium heating tubes behind the front panel, the radiator generates significantly higher BTU and Wattage output within the same wall footprint. This makes the double column model the correct technical solution for larger rooms or spaces with high heat loss where a single panel would not provide adequate warmth.
What are the precise wall projection dimensions for the Casina Double Column radiator and will it obstruct narrow walkways?
The Reina Casina Double Column radiator has a wall-to-front projection of approximately 86mm. This is a slim profile for a high-output double radiator, achieved through the flat-tube aluminium design. When installed, the front face sits closer to the wall than many traditional steel double panel radiators (Type 22), making it an excellent problem-solving option for hallways or landings where you need high heat output but must maintain clear passage width.
Why is the Reina Casina Double Column range recommended for use with low-temperature renewable heating systems like heat pumps?
This radiator combines two critical technical features for heat pump efficiency: high thermal conductivity and large surface area. Aluminium transfers heat 5x faster than steel, and the double panel design maximizes the contact area with the air. This ensures the radiator can emit effective warmth even when the water temperature flowing through it is lower (e.g., Delta T30 or 40 degrees Celsius), which is typical for air source and ground source heat pump systems.
Does the 10 Year Guarantee provided with the Reina Casina Double radiator cover the finish as well as the structure?
Yes, the 10 Year Guarantee covers the physical integrity of the aluminium structure (against leaks and manufacturing defects) and the durability of the powder-coated finish. The radiator is finished in a high-quality textured White (RAL 9016) or Anthracite coating that is thermally stable. This ensures the paint will not crack, peel, or discolor under the expansion and contraction cycles of the heating system for the duration of the warranty.
Are the vertical and horizontal versions of the Reina Casina Double Column interchangeable during installation?
No, you must select the specific orientation required for your space. The vertical and horizontal models are technically manufactured with internal flow diverters positioned differently to ensure correct water circulation. Installing a vertical model horizontally (or vice versa) would prevent the water from flowing through all the aluminium sections, leading to cold spots and significantly reduced heating performance.
How does the low water content of the Casina Double Aluminium Radiator reduce energy consumption in my central heating system?
Despite being a double panel radiator, the Casina holds a relatively low volume of water due to its narrow aluminium channels. This technical benefit means your boiler or heat pump has less water mass to heat up, resulting in a faster cycle time. The radiator reaches optimum operating temperature in minutes rather than hours, reducing the total "on-time" of your energy source and providing a more responsive heating system that reacts quickly to thermostat changes.
What specific valve connection type is required for the Reina Casina Double and where are the tapping points located?
The Reina Casina Double Column radiator utilizes standard 1/2 inch BSP (British Standard Pipe) connections, which are universal for UK plumbing. The tapping points (inlets) are located on the sides of the bottom of the radiator. For a standard installation, you will need Angled valves if your pipes come from the wall, or Straight valves if your pipes come up from the floor. The side connections allow for easy access and maintenance without disturbing the radiator mounting.
Can the Reina Casina Double Column radiator be installed on internal stud walls given its higher heat output and size?
Yes, this is a major problem-solving advantage of aluminium. Although it is a double panel unit with high heat output, the Reina Casina is significantly lighter than an equivalent steel double convector radiator. This reduced weight load means it can often be safely installed on internal plasterboard or stud walls using standard fixings, whereas a heavy steel alternative might require the wall to be reinforced or opened up to add timber support noggins.
Is the textured finish of the Reina Casina Double harder to clean than a smooth steel panel radiator?
The textured powder coat finish is designed to be durable and low maintenance. While it has a tactile surface, it does not trap dust excessively. The flat vertical columns are spaced to allow easy access for a duster or soft brush between the sections. Unlike steel panel radiators with complex convection fins (grills) inside the top, the open column design of the Casina allows you to easily clean the entire surface area, preventing dust build-up which can impede heat convection.
Does the modular sectional construction mean I can extend the width of the Reina Casina Double radiator later?
The Reina Casina is manufactured using a sectional process, but the Double Column units are factory-assembled and pressure tested as complete sealed units. Technically, you cannot easily add or remove sections on-site after purchase without specialist tools and compromising the 10 Year Guarantee. It is essential to use a BTU calculator to determine the exact heat output and width you need before ordering to ensuring the unit is perfectly sized for your room's heat loss requirements.
