Horizontal radiators are the UK's most trusted home heating solution — and our collection at Tiles Paradise UK proves they don't have to be ordinary. Wide, powerful, and elegantly proportioned, these wall-mounted radiators deliver balanced warmth across every room while sitting seamlessly beneath windows, along low walls, and anywhere efficient heating matters most.
Placing a radiator beneath a window is one of the most thermally effective positions in any room. Warm air rising from the panel meets cooler air dropping from the glass above, creating a natural convection current that circulates heat evenly throughout the space — no cold spots, no wasted energy.
Beyond their thermal logic, horizontal radiators offer wide size flexibility, straightforward installation into existing UK pipework layouts, and a proportionate look that suits rooms with standard ceiling heights far better than any alternative.
Flat Panel Radiators — Slim, low-projection designs in single panel (Type 11) or double panel (Type 22). The double panel option nearly doubles heat output from the same footprint — ideal for larger or colder rooms.
Column Radiators — Traditional multi-column structure with a wide surface area for superior heat retention. Works beautifully in both period and contemporary interiors, particularly under bay and sash windows.
Designer Horizontal Radiators — Bold profiles, oval tubes, and sculpted panels that turn a functional fitting into an intentional interior feature.
Low-Level Radiators — Compact in height, powerful in output. Designed specifically for shallow window recesses, conservatory knee walls, and under-stair spaces.
Electric Horizontal Radiators — Independent room control with no pipework required. Perfect for extensions, home offices, and loft conversions.
All models are manufactured from high-grade mild steel or aluminium for fast heat-up, strong retention, and lasting durability.
Horizontal radiators are the most versatile format available. They perform brilliantly in living rooms under external windows, in family bathrooms with floor pipework, in kitchens between units, in hallways along wide wall runs, and in bedrooms where a standard-height panel sits naturally beneath the windowsill. For rooms where wall width is limited, our vertical radiator collection offers the space-saving alternative.
BTU — Calculate your room's required heat output based on floor area, ceiling height, and window count. Matching BTU to your space prevents both under-heating and wasted energy. Use our BTU calculator or ask our team.
Single vs. Double Panel — Single panel suits smaller, well-insulated rooms. Double panel is the right call for larger spaces or anywhere that consistently runs cold.
Wall Width — For under-window fitting, measure the internal recess width and choose a radiator that sits within it comfortably without extending past the frame.
Valve Type — Valves are sold separately. Angled valves suit floor-entry pipes with side connections; straight valves suit floor-entry with bottom connections; corner valves suit wall-entry pipes. Confirm your pipework configuration before ordering.
Browse our full range above, filter by finish, BTU output, or height, and find the right horizontal radiator for your space. Need help choosing? Contact our team — we're happy to guide you to the perfect fit, fast UK delivery included.
