Frequently Asked Questions
What makes the Tallis Vertical Column Radiator different from standard panel radiators in terms of heat output?
The Tallis Vertical Column Radiator is designed with a high performance double column configuration that maximizes surface area for heat transfer. Unlike standard flat panel radiators, the Tallis range features robust vertical columns that allow for greater water volume and air circulation. This results in exceptional heat outputs, such as 6486 BTUs (1901 Watts) for the 1820mm x 600mm model, making it a powerful heating solution for large rooms with high ceilings or poor insulation.
What are the exact depth dimensions I need to allow for when installing a Tallis Double Vertical Radiator?
The Tallis Double Vertical Radiator has a substantial product depth of 120mm due to its deep double column structure. When planning your installation, you must add the depth of the wall brackets to this 120mm figure to calculate the total projection from the wall. This is significantly deeper than standard radiators, so it is critical to measure your available floor space and door clearances to ensuring the radiator does not become an obstruction in narrow hallways or landings.
Are the Tallis Vertical Radiators available in custom colours or only in standard White?
While the standard stock finish for the Tallis Vertical range is a crisp White RAL 9016, which is available for fast delivery, the product page indicates that customization is possible. You can order these radiators in a specific S4H RAL Colour or a Special Finish to match your interior design scheme. However, opting for a bespoke finish is a special order process that will typically incur a longer lead time compared to the off the shelf White option.
How does the 1820mm height of the Tallis Vertical model benefit rooms with limited wall space?
The 1820mm vertical height is a technical design feature intended to save horizontal wall space. By utilizing the vertical plane, a narrow model like the 1820mm x 300mm unit can be installed on slim pillars or tight wall sections where a traditional horizontal radiator would not fit. Despite its narrow 300mm width, it still delivers a powerful 3241 BTUs, allowing you to heat a room effectively without sacrificing space needed for furniture or appliances.
What type of guarantee is provided with the Tallis Vertical Column Radiators?
The Tallis Vertical Column Radiators are backed by a comprehensive 10 Year Guarantee. This warranty covers manufacturing defects such as leaks, weld failures, or material corrosion under normal operating conditions. It reflects the high quality of the steel construction and the durability of the finish. To ensure the validity of this guarantee, it is essential that the radiator is installed by a qualified professional and that the heating system is properly flushed and treated with a corrosion inhibitor.
Do I need to buy specific valves for the Tallis Vertical Radiator connections?
Yes, the Tallis Vertical Radiators are sold without valves, so you must purchase them separately. The radiators feature standard 1/2 inch BSP connections. Because the connections are typically located on the bottom sides or underside depending on the specific model layout, you will need to choose Angled, Straight, or Corner valves based on where your pipework emerges (floor vs wall). The choice of valve also allows you to add a thermostatic control for better energy efficiency.
How many sections are included in the varying widths of the Tallis Vertical range?
The width of each Tallis Vertical radiator is determined by the number of steel sections it contains. For example, the 300mm wide model consists of 10 sections, the 480mm wide model has 16 sections, and the 600mm wide model has 20 sections. This section count is a key technical detail because it directly impacts the weight of the radiator. A 20 section double vertical model is significantly heavy, so you must ensure your wall is structurally sound enough to support it.
Is the heat output listed for the Tallis range calculated at Delta T50 or a different rating?
All heat output figures listed for the Tallis Vertical Column Radiators, such as 5190 BTUs for the 1820mm x 480mm model, are calculated at Delta T50 (?t 50
Can the Tallis Vertical Radiator be installed on a standard UK central heating system?
Yes, the Tallis Vertical Column Radiator is fully compatible with standard UK central heating systems, including both open vented and sealed systems like combi boilers. It is manufactured from steel, which ensures rapid heat up times and responsiveness to thermostatic controls. The standard pipe connections ensure it can replace existing radiators with minimal modification to pipework, provided the pipe centers are adjusted to accommodate the radiator's width and wall projection.
Why is the Tallis Double Vertical model described as a high heat output radiator?
The "Double" designation in the Tallis Double Vertical model refers to its dual rows of columns, which effectively doubles the surface area compared to a single layer radiator of the same dimensions. This increased surface area allows for a much higher volume of heat to be radiated and convected into the room. For example, a relatively compact 1820mm x 420mm model outputs over 4500 BTUs, classifying it as a high output radiator suitable for demanding heating requirements in large or open plan spaces.
