FAQ
What kind of wall fixings are included?+
Each radiator typically comes with a selection of plastic plugs and rawl bolts suitable for mounting onto non-combustible walls, such as plasterboard. However, always ensure the wall is appropriate for supporting the weight of the radiator – consult a building professional if unsure.
Do I need to bleed these radiators?+
Yes, all panel heaters require regular bleeding to remove trapped air and maintain optimal performance. Bleeding should be done periodically, particularly after periods of inactivity or temperature changes.
What size room is a 2500W radiator suitable for?+
A 2500W radiator is generally best suited for rooms up to approximately 20 square metres. Larger spaces will require multiple radiators for effective heating.
Are these radiators safe to use with children?+
All electrical appliances should be kept out of reach of small children. Ensure adequate ventilation around the radiator and regularly check for any signs of damage or overheating.
What type of flow gauge is included?+
The supplied flow gauges are typically simple, adjustable valves that allow you to control the water flow rate through the radiator, influencing its heat output.
Can I use these radiators with a standard UK heating system?+
Yes, these radiators can be used with most standard UK heating systems. However, it’s crucial to ensure compatibility with your existing system pressures and temperatures – consult a qualified engineer if necessary.
What is the warranty on these radiators?+
The manufacturer's warranty typically covers defects in materials and workmanship for a period of one year. Refer to the product documentation for full details regarding coverage.
How do I install the wall brackets?+
The wall brackets are usually easy to fit, requiring only a screwdriver. Ensure you select a suitable fixing point on the wall, considering its load-bearing capacity and adhering to building regulations.
What is the flow gauge used for exactly?+
The flow gauge regulates the water temperature passing through the radiator, allowing you to adjust the heat output based on your comfort preference. Turning it fully open delivers maximum heat, while closing it reduces the flow rate and therefore the heat produced.
What if the radiator leaks?+
If a leak occurs, immediately turn off the water supply at the isolating valve. Contact the manufacturer for assistance – Amazon’s standard returns policy may not cover damage caused by improper installation or use; check Amazon's terms for details.
