Factors to consider while buying oil filled radiators
When buying an oil-filled radiator, consider the following factors to ensure you choose the best option for your needs:
Heating Capacity (Wattage): Choose a radiator with the appropriate wattage for the size of your room. Higher wattage (e.g., 2000W or more) is better for larger rooms, while lower wattage is suitable for smaller spaces.
Portability: If you plan to move the heater around, look for features like castor wheels or a handle for easy transportation. A lightweight design also helps with mobility.
Safety Features: Check for essential safety features such as overheat protection, tip-over switches, and thermal cutoffs. These ensure the radiator automatically turns off if it becomes too hot or is accidentally tipped over.
Size and Design: Consider the radiator’s size and appearance. It should fit comfortably in your space and match your home decor. Some models also have a slim or compact design, making them easier to store when not in use.
Thermostat and Adjustable Settings: An adjustable thermostat allows you to set the desired temperature for personalised comfort. Additionally, multiple heat settings (e.g., low, medium, high) provide flexibility based on your needs.
Energy Efficiency: Look for energy-efficient models that retain heat well. Oil-filled radiators tend to be more efficient since the oil inside retains heat for a longer time, helping save on electricity bills.
