Quick guide from the manual
This document serves as a technical specification sheet for the Reina Colona Horizontal mild steel radiator. It provides essential data for installation planning, including dimensions, pipe center measurements, and heat output ratings. Please note that this document does not contain step-by-step installation instructions; it is intended for sizing and specification purposes.
Product overview
The Reina Colona Horizontal is a mild steel radiator available in various sizes and finishes, including white, anthracite, and raw steel lacquer. The product comes with a 5-year guarantee.

Technical specifications
The radiator is available in multiple configurations. Key technical parameters provided in the documentation include:
- Height and Width: Various dimensions ranging from 300mm to 600mm in height and 605mm to 1370mm in width.
- Pipe Centres: The distance between pipe connections varies by model. Important: For pipe centre measurements including valves, you must add 90mm to the listed value.
- Wall Distance: The distance from the wall to the radiator face.
- Fuel Type: Models are compatible with Central Heating (C), Electric (E), or Dual Fuel (D) systems.
Heat output data
The manual provides detailed heat output tables for central heating configurations. Outputs are measured in both BTU and Watts at two different temperature differentials:
- ΔT50°C: Standard output for modern heating systems.
- ΔT60°C: Output often used for older heating systems or specific design requirements.
Users should consult the specific model/SKU table in the document to determine the correct heat output for their chosen radiator size and finish.
Practical help
Common problems
Ensure you add 90mm to the listed 'Pipe Centres' measurement if you are including valves in your calculation.
Check the 'Fuel Type' column in the technical data table. Most models support Central Heating (C), Electric (E), and Dual Fuel (D), but some are limited to Central Heating only.
Before use
- Verify the wall structure can support the weight of the radiator.
- Confirm the required heat output (BTU/Watts) for the room size.
- Check the 'Pipe Centres' dimension for your specific model.
- Add 90mm to the pipe center measurement if installing valves.
- Verify the chosen fuel type (Central Heating, Electric, or Dual Fuel) matches your system.
