High Output Vertical Radiators

Eliminate cold spots in your largest rooms with our market-leading range of high-output vertical radiators. At Trade Radiators, we specialise in "powerhouse" heating solutions designed for challenging spaces such as open-plan kitchen extensions, high-ceilinged hallways, and draughty period lounges. By utilising the vertical plane, these radiators deliver a massive thermal punch from a narrow footprint, allowing you to heat a room of up to 500 sq. ft. with a single, stylish unit.

Our collection features heavy-duty designs from trusted UK and European brands, including DQ Heating, Apollo, and Nordic. Every high-BTU model is engineered for maximum heat emissivity, ensuring your home remains cosy even during the peak of the UK winter.

Engineering Maximum Warmth: Columns & Convection

The secret to a high-output vertical radiator lies in its surface area. By increasing the number of columns or adding secondary panels (K2/Double Panel designs), these radiators allow for greater heat dissipation and more powerful convection currents. Our most potent models produce up to 11,460 BTU (3360W), capable of transforming a cold 46 sq. m room into a comfortable living space. Unsure of your requirements? Grab a tape measure and use our free BTU heating calculator to find your optimal power range.

Popular Sizes for Large-Scale Heating

Whether you need a discreet unit to tuck into a corner or a central statement piece, we offer a variety of sizes to suit your architecture:

• 1800mm x 600mm: Our "Gold Standard" for high-output living room heating.
• 1760mm x 620mm: A wide-format vertical for massive heat dispersal.
• 1800mm x 300mm: A narrow but deep double-panel solution for tight alcoves.

Built for Performance and Longevity

A high-BTU radiator must be robustly constructed to handle high water volumes and temperatures. Our vertical powerhouses are manufactured from 1.2mm high-grade mild steel or lightweight aluminium, ensuring optimal response times and durability. Features include a neat 105mm wall projection (typical) and multi-section designs for even heat dispersal. For a complete installation, ensure you pair these units with high-flow radiator valves to maintain consistent water pressure.
