Choosing between an Oil Filled Radiator vs Storage Heaters: Which Wins? can be tricky, especially if you’re new to home heating. The details of how each works and their pros and cons might seem overwhelming at first. But don’t worry! This guide will break down everything in simple steps, making the process easy to follow. We’ll explore the differences so you can make the right decision for your home. Let’s get started!
How Oil Filled Radiators Work
Oil filled radiators are a common type of heater used in homes. They’re pretty easy to operate and can be a good choice for certain situations. Inside, these heaters have a sealed chamber filled with oil. When you switch on the heater, electricity heats up the oil. The oil then stores the heat and slowly releases it into the room. This process allows the radiator to keep radiating warmth even after it is switched off. Because the oil is contained, these heaters are generally considered safe, and they don’t require any special setup.
Key Features of Oil Filled Radiators
Radiant Heat: Oil filled radiators mainly use radiant heat, which means they warm objects directly. Unlike convection heaters that heat the air, radiant heat travels in straight lines and warms whatever it hits. Think of how the sun warms your skin.
Radiant heat makes these radiators effective at heating specific areas or smaller rooms. Because they heat objects directly, the effect is noticeable quickly. This is especially good if you need a quick boost of warmth in a chilly room. The heat is less affected by drafts, maintaining a more even temperature. Also, this type of heating is typically quiet and doesn’t circulate dust as much as some other types of heaters.
Safety Advantages: Since the heating element is sealed within the oil, oil filled radiators are generally considered safe. There are no exposed heating coils that can be touched. They usually have safety features like automatic shut-off to prevent overheating.
The sealed nature of these heaters means less risk of fire hazards. Many models also have tip-over protection, which turns off the heater if it is accidentally knocked over. The outside surface of the radiator usually doesn’t get as hot as other types of heaters, further reducing the risk of burns. These safety aspects make them suitable for homes with children or pets.
Portability: Most oil filled radiators are designed to be easily moved from room to room. They often come with wheels and handles. This allows you to place them where they’re needed most.
The portability of an oil filled radiator is a real advantage. You can move the heater to where you’re spending time, allowing for localized heating and saving energy. This is especially useful for those who only need heat in certain areas of their home. You don’t have to heat the whole house, which can lower your energy costs. The ability to move the radiator also makes it ideal for use in temporary or seasonal living spaces.

Overview of Storage Heaters
Storage heaters are a different approach to home heating. They are designed to store heat during off-peak hours when electricity costs are lower. They then release this heat throughout the day. This makes them a more economical option for certain users. The core of a storage heater is made up of bricks or ceramic blocks that absorb heat. These blocks are heated up overnight and then gradually release warmth during the day. This provides a more consistent, long-lasting heat, but it also means that the heating is less responsive to sudden temperature changes.
The Advantages and Disadvantages
Off-Peak Electricity Use: One of the main benefits of storage heaters is their ability to use cheaper, off-peak electricity. This can significantly reduce energy bills, especially for those on special tariffs.
The economic advantage here is substantial. Off-peak electricity is often significantly less expensive than standard rates. By charging the heater overnight, you can heat your home at a fraction of the cost. This is good for individuals and families on a budget, making it easier to afford home heating during colder months. It also helps to spread energy demand, which is good for the power grid.
Consistent Heat Output: Storage heaters provide a steady heat output throughout the day. This is achieved by the slow release of heat from the storage materials. This makes them good at maintaining a stable, comfortable temperature.
This steady warmth is a big benefit for those who don’t want temperature fluctuations. Because the heat is released over many hours, you don’t need to constantly adjust the thermostat. This consistent temperature can be very helpful in homes where the occupants want a stable and predictable environment. However, it can be a disadvantage if you need rapid heating or prefer to switch off the heat completely during parts of the day.
Initial Cost and Installation: Storage heaters can be more expensive to buy than some other heating systems. Installation also might require more work, especially if you need to install a special electricity meter for off-peak rates.
While the long-term running costs may be lower, the upfront costs can be an obstacle. This makes them less accessible to those on tight budgets. The more complex installation may also require professional help, adding to the initial investment. Before purchasing storage heaters, you need to consider the total cost, not only the ongoing energy savings.
Comparing Oil Filled Radiator vs Storage Heaters: Which Wins?
When choosing between an Oil Filled Radiator vs Storage Heaters: Which Wins? depends on your specific needs and situation. Both types have advantages and disadvantages. Oil filled radiators are known for their ease of use, portability, and safety. Storage heaters excel at using off-peak electricity, offering potential cost savings. Understanding these differences will help you make the right choice.
Energy Efficiency Considerations
Operational Energy Use: Oil filled radiators convert electricity directly into heat when they’re turned on. They are 100% efficient in doing this, meaning all the electricity is used to produce heat. However, since they run only when switched on, their running cost depends on electricity prices at the time.
Oil filled radiators can be very efficient during the time they’re in use. They heat the room quickly, allowing you to control energy use by switching them on when you need them. The cost of running these heaters can go up during peak electricity times, which is a factor to consider. These are more appropriate for smaller rooms or supplemental heating needs.
Storage Heater Efficiency: Storage heaters take advantage of off-peak electricity, which can be cheaper. They store heat, releasing it slowly over time. The efficiency depends on how well the heat is stored and how much is lost to the surroundings.
The energy efficiency of storage heaters comes from their ability to use less expensive electricity during off-peak hours. The efficiency of the storage itself affects how long the heat lasts and how much is wasted. To gain the best advantage, you have to use a storage heater correctly, planning the settings to match your heating needs. This also involves understanding how to manage the heat output during the day, so you don’t waste energy.
Energy Cost Comparison: The main factor influencing the cost is the rate you pay for electricity. Oil filled radiators can be cheaper if used for short periods or when electricity rates are low. Storage heaters can offer savings if they’re used with an off-peak tariff.
The price of electricity at the time of use is the key factor when using oil filled radiators. If you run them during peak hours, it can be more expensive. Storage heaters give you the chance to avoid those higher prices by storing heat when electricity is cheap. The ultimate cost difference varies depending on your energy tariff, the size of your home, and your heating habits.
