Bring a practical heating solution and a considered finish to your interior with the Supplies4Heat Larkin Double Horizontal radiator. Its horizontal design suits a variety of room layouts, while the double configuration offers a different option from the single version in the Larkin range.

Constructed from mild steel, this radiator has a straightforward design that works in both contemporary and more traditional spaces. It can be a good fit beneath a window or along a wider section of wall, depending on the dimensions of your room.

Choose a size that works for your room

The Larkin Double Horizontal is available in three sizes: 520mm high by 1,200mm wide, 600mm high by 900mm wide, and 600mm high by 1,200mm wide. Heat output ranges from 3,637 to 4,852 BTU/h at T50, depending on the model.

When deciding which size to buy, consider the available wall space as well as the amount of heat your room needs. Insulation, window size and room dimensions can all influence the output required.

Matt White or a RAL colour finish

Choose Matt White for a clean, understated appearance, or explore the RAL colour option if you'd like to coordinate the radiator with a particular interior scheme. A complementary shade can help the radiator blend into the room, while a contrasting colour can make it a more noticeable feature. Confirm the available RAL colours before ordering.

Check the installation dimensions

Designed for central heating systems, the Larkin Double Horizontal has a listed wall-to-pipe-centre measurement of 76–82mm and a wall-to-face depth of 116–122mm. Pipe centres are 870mm for the 900mm-wide model and 1,170mm for the 1,200mm-wide models.

If you're replacing an existing radiator, compare these measurements with your current pipework and available clearance. The double configuration may also require more space from the wall than a single model, so check the dimensions before installation.

A considered option for everyday heating

With its choice of sizes and finishes, the Supplies4Heat Larkin Double Horizontal offers flexibility when planning a room update or choosing radiators for a renovation. It is made from mild steel, designed for central heating and listed with a 10-year warranty in the supplied product specifications.

Q1: What is the difference between the Larkin Single and Double Horizontal radiators?+

They are different configurations within the Larkin range. Compare the heat output, dimensions and wall clearance of each version to decide which is suitable for your room and installation.

Q2: Does the double version need more space behind it?+

The supplied specifications list a wall-to-face depth of 116–122mm for the Double Horizontal. Check the available clearance around the radiator, including space for valves and pipe connections, before fitting.

Q3: Can I replace a Larkin Single with a Larkin Double?+

Possibly, but you should not assume they will fit in exactly the same way. Compare the dimensions, pipe centres and wall clearance of both models, and ask a qualified installer to check whether your existing pipework and mounting arrangements are suitable.

Q4: Which model has the highest heat output?+

The 600mm-high by 1,200mm-wide model has the highest listed output at 4,852 BTU/h (1,422W) at T50. Check your room's heat requirements before choosing it based on output alone.

Q5: Is the RAL colour option suitable for a coordinated interior scheme?+

The RAL Colour option gives you an alternative to Matt White when planning your room's colour scheme. Confirm the available colour references with the retailer before placing your order, particularly if you're matching other fixtures or finishes.

Q6: What should I measure before ordering?+

Measure the available wall width and height, check the pipe positions and allow for the radiator's depth. The listed pipe centres are 870mm or 1,170mm, depending on the width, and the wall-to-face depth is 116–122mm.

Q7: How can I tell if the radiator will heat my room adequately?+

Compare its listed T50 heat output with the room's calculated heat requirement. Room dimensions, insulation, glazing and external walls can affect how much heat is needed, so a heat-loss calculation is more reliable than choosing by room type alone.

Q8: What warranty is supplied with the Larkin Double Horizontal?+

The supplied product data lists a 10-year warranty. Review the manufacturer's warranty terms for details of coverage and any conditions that apply.
