FAQ
What does 1.5kW mean?+
1.5kW refers to the power output of the radiator, measured in kilowatts. This indicates the rate at which it converts electrical energy into heat – a higher kW value means more heat is produced.
How do I calculate the BTU needed for my room?+
BTUs (British Thermal Units) measure the amount of heat required to warm a room. A general rule of thumb is 10 watts per square foot, but factors like insulation and window size significantly affect this calculation. Use an online BTU calculator for more precise results.
Can I paint these radiators?+
Yes, you can generally paint the steel surfaces of these radiators using suitable paints specifically designed for metal. Ensure the paint is fully dry before operating to prevent damage or warranty invalidation – always check the manufacturer’s guidelines.
What type of radiator valves are compatible?+
These radiators typically accommodate standard UK thermostatic radiator valves (TRVs), which are readily available and allow for precise temperature control. Ensure you purchase TRVs with a suitable connection size to avoid leaks or damage.
Do I need to fit these radiators myself?+
Installation can be done DIY, but we recommend consulting a qualified heating engineer for safe and correct installation, especially if connecting to existing plumbing systems. Incorrect installation could void the manufacturer's warranty.
What is the warranty on these radiators?+
The radiator warranties are provided directly by the manufacturers. Please refer to the individual product page for specific warranty details regarding duration and coverage – typically 5-10 years against manufacturing defects.
Are there different finishes available?+
Yes, a variety of finishes are available across this collection including white, chrome, matte black, and brushed silver. The exact colour options available will vary by individual radiator model; please check the product listing for details.
How do I adjust the height of the radiators?+
Most models feature adjustable feet that allow you to level the radiator and fine-tune its positioning against walls or furniture. Ensure the feet are securely tightened for stability.
What’s the difference between a vertical and horizontal radiator?+
Vertical radiators are best suited for hallways and smaller rooms, while horizontal radiators are typically better for larger rooms like living rooms where they can provide wider heat distribution. Consider the room dimensions when selecting your radiator type.
Can I connect these radiators to a smart thermostat?+
While possible, compatibility with smart thermostats varies by manufacturer and model. Check the individual product specifications or consult a heating engineer for advice on integration before purchasing.
