Review: Insignia Oil Filled Radiators – Are They the Best Buy for Your Home?

When the chill of winter sets in, finding an effective and efficient way to warm your living space becomes a top priority. Oil filled radiators have long been a popular choice for supplemental heating, offering a unique blend of consistent warmth and quiet operation. But with so many options available, how do you determine which one is truly the best buy for your home? Let’s delve into the world of oil filled radiators, specifically examining the Insignia brand, to help you make an informed decision.

What is an Oil Filled Radiator?

An oil filled radiator is a type of electric heater that utilizes diathermic oil, permanently sealed inside its metal fins, as a heat reservoir. An electrical heating element submerged within this oil warms it up. As the oil heats, it circulates throughout the radiator’s columns through convection, transferring heat to the outer metal surface via conduction. This warm surface then radiates heat into the room and warms the surrounding air through convection.

The primary advantage of this design is its exceptional heat retention. Once the oil reaches its set temperature, the heating element cycles on and off less frequently because the oil continues to emit warmth even after the element is off. This high thermal inertia provides a gentle, consistent heat that doesn’t dry out the air, creating a comfortable environment. They are also renowned for their virtually silent operation, making them ideal for bedrooms and offices. Compared to other heater types, oil filled radiators generally offer a safer surface temperature, reducing burn risks. Their portability, often featuring castor wheels, allows them to be moved easily to heat specific areas.

However, oil filled radiators do have some drawbacks. They typically take longer to reach the desired room temperature compared to fan or ceramic heaters because they rely on heating the oil first. Larger models can also be quite bulky and heavy, despite having wheels. While efficient for supplementary heating, they are usually best suited for medium to small-sized rooms, typically up to 270 square feet, rather than serving as a primary heat source for an entire large home.

Types of Oil Filled Radiators and Key Features

Oil filled radiators come in various configurations, each designed to meet different heating needs and preferences. Understanding these types and their features is crucial for selecting the right model.

Power Output and Room Size

The heating capacity of an oil filled radiator is primarily determined by its wattage, ranging from around 500W to 2500W. A general guideline is to allocate approximately 100 watts of power for every square meter of space, or about 10 watts per square foot, in a well-insulated room. For instance, a 1500-watt radiator is generally effective for rooms up to 150 square feet, while larger spaces, such as studio apartments or expansive living areas, might require a 2000W or 2500W unit. Selecting the correct wattage ensures efficient heating without overworking the appliance or consuming unnecessary energy.

Design and Heat Distribution

The distinctive design of oil filled radiators, characterized by multiple curved columns or “fins,” is not just for aesthetics; it significantly increases the surface area. A larger surface area allows more air to come into contact with the radiator, enhancing heat transfer through convection and radiation. Some modern designs feature wave-shaped fins, which further optimize the surface area for even faster and more efficient heat dispersion compared to plain fin designs. The number of fins often correlates with the heater’s wattage, with more powerful units typically having more fins.

Smart Features and Controls

Modern oil filled radiators often include advanced features for improved convenience and energy management. Electronic thermostats allow you to set a precise desired temperature, with the heater cycling on and off to maintain it, thus preventing overheating and saving energy. Programmable timers, sometimes offering 24-hour or 7-day schedules, enable you to automate heating cycles to match your daily routine. Remote controls provide effortless temperature adjustments from across the room, while eco-modes can optimize power consumption for greater efficiency.

Safety Mechanisms

Safety is paramount for any heating appliance. Quality oil filled radiators are equipped with several safety features.
