One To Avoid

Midea 11 Fins Electric Oil Heater with Remote Control & LED Touch Screen

We tested the Midea 11 Fins Electric Oil Heater and found it to be more style than substance. While it does offer quick heating (thanks to its Arrowfly Heating Technology) and operates quietly, several glaring issues overshadow these positives.

The thermostat, a critical feature, is wildly inconsistent. It struggles to maintain the set temperature, leading to frequent and frustrating fluctuations. The lack of a proper timer to schedule specific on/off times further limits its usability.

Additionally, the auto-shutoff after 12 hours means it can’t be relied upon for continuous heating without manual intervention.

Design-wise, the heater looks modern and is easy to move with its wheels and handle. Safety features like overheat protection and a tip-over switch are welcome additions. However, durability is questionable, with some components feeling flimsy, raising concerns about its long-term reliability.

While it may work as a temporary heating solution, the overall experience is disappointing. If you value consistent performance and hassle-free operation, this heater is not the best choice. The Midea 11 Fins Electric Oil Heater promises a lot but ultimately fails to deliver on the most important aspects. We’d recommend looking elsewhere.

How We Evaluated and Chose the Best Oil-Filled Radiators

When testing oil-filled radiators, we didn’t simply rely on their heating capabilities. Instead, we conducted a comprehensive evaluation to ensure they excelled in performance, safety, design, and overall usability. Here’s how we assessed each model:

Heating Performance

We tested each radiator’s ability to warm a room efficiently, measuring how quickly it reached a comfortable temperature. Using thermometers and timers, we evaluated warm-up times and checked for even heat distribution across different spaces.

To ensure versatility, we tested each model in rooms of varying sizes and measured temperature changes at regular intervals. Consistent, reliable heating was a priority, especially for use in colder environments.

Energy Efficiency

Energy consumption was carefully monitored using power meters, comparing usage across multiple heat settings. We tested thermostat accuracy to ensure each radiator could maintain the desired temperature without excessive energy use.

Radiators with eco modes were further assessed to determine how effectively they conserved power while still providing sufficient warmth.

Safety Features

Safety was a crucial focus in our testing. We simulated overheating scenarios to evaluate the reliability of automatic shutoff systems and gently tipped radiators to confirm tip-over protection.

Infrared thermometers were used to monitor the temperature of external casings and fins, ensuring they remained safe to touch during operation, even after extended use.

Ease of Use

User experience was a key consideration. We examined the usability of controls, thermostat dial and timers, focusing on clear labelling and intuitive interfaces. Portability was tested by evaluating how easily the portable heaters could be moved using wheels, handles, or compact designs.

Additionally, setup and assembly processes were scrutinised to ensure they were straightforward and user-friendly, even for those unfamiliar with similar appliances.

Noise Levels

To ensure quiet operation, we used decibel meters to measure noise during use. Silent operation is particularly important in settings like bedrooms and offices, where excessive noise can disrupt relaxation or focus.

A radiator’s ability to maintain near-silent performance was highly valued in our assessments.

Durability and Build Quality

We inspected the materials and construction of each radiator, focusing on the quality of fins, casings, and wheels. Extended use was simulated by running the radiators continuously for several days to identify potential issues, such as performance degradation or signs of wear and tear.

Models with robust materials and solid construction scored higher for their ability to withstand regular use.

Extra Features

Radiators with additional features stood out during testing. We evaluated functionalities like timers, remote controls, and digital displays for accuracy and convenience. Cord length and storage options were also reviewed, as these details can significantly impact a unit’s usability.

Models with thoughtful extra features, such as eco modes or frost protection, earned higher marks.

Real-Life Scenarios

To provide a realistic evaluation, we tested radiators in various settings, including small bedrooms, spacious living rooms, and drafty areas. Performance in temperature extremes was also examined, ensuring the radiators could deliver reliable heating even in the coldest conditions.

Aesthetic Appeal

Design was an important consideration, as oil filled heaters should complement home decor rather than detract from it. We assessed models with modern, sleek designs and neutral finishes that could easily blend into different interior styles.

Compact and space-saving designs were also prioritised for smaller living spaces.

Value for Money

Finally, we compared the performance, features, and build quality of each radiator against its price. Models that offered exceptional heating efficiency, safety, and useful extras while maintaining a reasonable price were considered the best investments.

Frequently Asked Questions

Do Oil Radiator Heaters Use a Lot of Electricity?

Oil radiator heaters do not necessarily use a lot of electricity, as their energy efficiency depends on factors like wattage, room size, and thermostat settings. They retain heat even after being turned off, which helps conserve energy.

Proper use of eco modes and thermostats can further minimise electricity consumption.

Where Is the Best Place to Put an Oil-Filled Radiator?

The best place to put an oil-filled radiator is in an area with good air circulation but away from obstructions like furniture or curtains. Positioning it near a cold source, such as windows or exterior walls, can help counter drafts and ensure even heat distribution throughout the room.

Can I Leave an Oil-Filled Radiator on Overnight?

You can leave an oil-filled radiator on overnight, as they are designed with safety features like overheat protection and tip-over switches. However, ensure it is placed on a flat, stable surface and set to a low, consistent temperature to avoid excessive energy use or overheating risks.

Do Oil-Filled Radiators Need Refilling?

Oil-filled radiators do not need refilling because the oil inside serves as a heat reservoir and is not consumed or evaporated. The sealed system ensures that the oil remains intact throughout the radiator’s lifespan, requiring no maintenance in this regard.

How Do You Maintain an Oil-Filled Radiator?

To maintain an oil-filled radiator, clean the exterior regularly to remove dust and debris. Inspect the power cord for wear and tear, and ensure the wheels and handles are secure. Store it in a dry, safe place when not in use, and follow the manufacturer’s instructions for proper care.
