The Ultimate Buyer’s Guide: How to Choose The Right Product for You

Key Factors to Consider

When searching for the best cheap electric heater to run, several factors go beyond just the initial purchase price. We always consider the wattage and heat output relative to the room size. A heater that’s too small will struggle to warm a large space, running constantly and inefficiently, while an oversized one is overkill. The heating method is also crucial: radiant heaters (like oil-filled or panel heaters) provide a steady, ambient warmth, while fan heaters offer rapid, directed heat. Think about how quickly you need warmth and for how long. Safety features are paramount; always look for tip-over protection, overheat auto-shutoff, and flame-retardant materials. For optimal running costs, an adjustable thermostat and an ECO mode are non-negotiable, as they allow the heater to cycle on and off to maintain a set temperature, rather than running continuously. Finally, consider portability if you plan to move the heater between rooms, and the noise level, especially for bedrooms or quiet workspaces.

Understanding Electric Heater Efficiency

Understanding what makes an electric heater “cheap to run” often comes down to energy management, not just raw power. While all electric heaters convert virtually 100% of electrical energy into heat (making them equally efficient at energy conversion), their running cost depends on how effectively they heat a space and how intelligently they manage that heat. For instance, a 1500W fan heater will use 1.5 units of electricity per hour on its highest setting. If your electricity costs £0.30 per unit, that’s £0.45 per hour. The “efficiency” from a user perspective comes from features like a precise thermostat (which prevents overheating and wasted energy), timers (to only run when needed), and oscillation (to spread heat faster, so it reaches comfort levels sooner and can switch off). Oil-filled radiators, like the Belaco models, are good at retaining heat, meaning they stay warm even after the element switches off, potentially reducing cycling frequency. Connected smart heaters, such as the Dreo Smart Wall Heater or Philips 3000 Series, can offer advanced scheduling and AI-driven modes that adapt to your usage, leading to significant savings by optimising when and how much heat is delivered.

Common Mistakes to Avoid

Through our testing and extensive observation of user experiences, we’ve identified several common pitfalls to sidestep when buying and using electric heaters. Firstly, avoid buying an undersized heater for a large room. It will work overtime, struggle to reach your desired temperature, and cost you more in the long run. Conversely, don’t overheat a small room with a powerful heater set to max; use the thermostat. A frequent mistake is ignoring safety features; always ensure your chosen heater has tip-over and overheat protection. We strongly advise against using extension cords with electric heaters, as they can easily overload circuits and pose a fire hazard—always plug directly into a wall socket. Another common error is not utilising a heater’s built-in thermostat or ECO mode; these features are designed to save you money by maintaining temperature rather than continuously heating. Lastly, consider the noise output if the heater is for a bedroom or quiet space; a cheap, loud fan heater might save on initial cost but compromise comfort.

Frequently Asked Questions

Which type of electric heater has the lowest hourly running cost?

Generally, a lower wattage electric heater will have a lower hourly running cost, assuming electricity prices are constant. For example, the Dimplex OFRB7N Eco Mini Oil Free Heater at 700W will cost less per hour to run than a 2000W fan heater. However, the overall cost depends on the size of the room and how long the heater needs to run to achieve and maintain comfort. For targeted, personal heating in a very small space, a low-wattage radiant heater can be the cheapest per hour. For larger spaces, a more powerful heater with an efficient thermostat and timer might be more economical overall as it heats up quicker and cycles off.

Are halogen heaters cheap to run for short periods?

Halogen heaters can be very efficient for short bursts of immediate, directed warmth. They operate by infrared radiation, directly heating objects and people rather than the air. This makes them ideal for quickly warming a person in a cold room or a small, poorly insulated area for brief periods. Their instantaneous heat delivery can feel very economical for short uses, as you don’t have to wait for the entire room to warm up. However, for prolonged heating of a whole room, they may not be as effective or energy-efficient as other types with thermostats.

Does a low purchase price usually mean higher running costs?

Not necessarily, but it’s a common trend. Very cheap fan heaters might lack advanced features like precise digital thermostats, ECO modes, or timers. Without these, they are more likely to run continuously or at higher power settings, potentially leading to higher energy consumption and running costs. More expensive models often incorporate smart technology, better insulation, and more accurate temperature controls designed to optimise energy use. However, some budget-friendly options, like the Dreo Atom 316 Ceramic Heater, offer excellent efficiency features for their price.

What features, like thermostats and timers, help lower running costs?

Thermostats are crucial for lowering running costs. They allow you to set a desired temperature, and the heater will automatically switch off once that temperature is reached, only turning back on when the temperature drops. This prevents unnecessary energy waste from overheating. Timers enable you to schedule the heater to turn on and off at specific times, ensuring it only operates when you need it. ECO modes (like those found in Dreo heaters and the Philips 3000 Series) intelligently adjust power output to maintain comfort with minimal energy use. Oscillation, while not directly saving energy, helps distribute heat faster and more evenly, meaning the room reaches comfort sooner and the heater can cycle off more quickly.

Are fan heaters expensive to use for several hours at a time?

Fan heaters, particularly those with higher wattages (e.g., 2000W), can become expensive if run continuously for several hours at maximum power. They excel at rapid, directed heating. However, if used with an effective thermostat and set to an appropriate temperature, a good fan heater will cycle on and off, reducing its average hourly consumption. Models with ECO modes, like the Dreo Fast Heating Portable Heater, are designed to manage this. For very long periods, especially in less insulated rooms, an oil-filled radiator might offer more consistent and potentially lower overall running costs due to its heat retention properties.

Can a heater under £50 still be economical to run?

Yes, absolutely. The Dreo Atom 316 Ceramic Heater is a prime example of an economical heater under £50. Many budget-friendly models still come equipped with essential features like adjustable thermostats and multiple heat settings. While they might lack some advanced smart features or wide oscillation, their ability to deliver targeted heat effectively, especially in smaller rooms, can make them very economical to run. The key is to match the heater’s power output and features to the size of the room and your specific heating needs, and always make use of its temperature control.

How does an oil-filled radiator compare to a fan heater in terms of cost?

Oil-filled radiators, like the Belaco 11 Fins Oil Filled Radiator 2500W, provide radiant heat that warms objects and air slowly but consistently, and they retain heat for a period after being switched off. This heat retention can make them more economical for maintaining warmth over longer durations, as they don’t need to cycle on as frequently. Fan heaters, on the other hand, offer instant, forced-air heat. They warm up a room very quickly but also cool down quickly once switched off. For short bursts of immediate heat, a fan heater might feel cheaper. For sustained, ambient warmth throughout the day or night, an oil-filled radiator often proves more cost-effective due to its heat retention and steady output, especially when managed by a thermostat.
