Halogen heaters have become popular as quick and portable heating solutions for homes, offices, and outdoor spaces. They’re lightweight, compact, and give off instant heat, making them a go-to choice for people who don’t want to wait for a central heating system to warm up an entire room.
But one of the most common questions people ask before buying one is: Are halogen heaters cheap to run?
Are Halogen Heaters Cheap To Run?
Yes, halogen heaters can be cheap to run, BUT only under specific conditions. They excel as low-cost, targeted heaters for short-term use, but become expensive if relied upon as a primary heat source. Here’s the breakdown:
Why Halogen Heaters CAN Be Cheap
- Targeted & Instant Heat: Unlike central heating that warms whole rooms (including unused space), halogen heaters use infrared radiation to directly warm people and objects in their path. This means less energy is wasted heating empty air.
- Lower Wattage Options: Available in very low wattages (100W – 400W), perfect for personal warmth at a desk or in a small area. Low wattage = low running cost per hour.
- No Warm-Up Time: They provide heat instantly, so you only use energy when you actually need warmth, unlike systems that need time to heat up.
Why Halogen Heaters CAN BE Expensive
- High Wattage Models = High Cost: Powerful models (1200W – 2000W) consume significant electricity. Running a 2000W heater for several hours daily costs substantially more than central heating per unit of heat delivered to a whole room.
- Inefficient for Whole-Room Heating: They don’t effectively heat the air in a large or poorly insulated space. To feel warm, you often need to run them longer or at higher settings, increasing costs.
- Costs Add Up with Prolonged Use: Their low hourly cost advantage disappears with extended daily use. Relying on one for 8+ hours a day becomes costly.
How Much Does it Cost to Run a Halogen Heater?
The running costs of any electrical appliance depend on its wattage and how long it’s used. Halogen heaters typically come in different wattages, ranging from small 100W desk heaters to large 2000W freestanding models.
Wattage is a measure of how much power the heater consumes.
- A 400W halogen heater uses 0.4 kWh (kilowatt-hours) if run for one hour.
- A 1200W model uses 1.2 kWh per hour, and so on.
If your electricity costs £0.30 per kWh (UK average in 2025), then:
- A 400W heater costs about 12p per hour.
- A 1200W heater costs about 36p per hour.
- A 2000W heater costs about 60p per hour.
If your electricity costs $0.165 per kWh (US average in 2025), then:
- A 400W heater costs about $0.066 (6.6¢) per hour.
- A 1200W heater costs about $0.198 (19.8¢) per hour.
- A 2000W heater costs about $0.33 (33¢) per hour.

How to Calculate Your Own Running Costs
If you want to figure out exactly how much a halogen heater will cost you, here’s a simple formula:
Running Cost = (Heater Wattage ÷ 1000) × Hours Used × Electricity Price per kWh
Example: Running a 1200W heater for 3 hours at £0.30 per kWh:
(1200 ÷ 1000) × 3 × 0.30 = £1.08
This formula works for any wattage and any electricity tariff. You can also use smart meters or online calculators to get a more precise idea of your costs, especially if your electricity supplier uses variable rates depending on the time of day.
Tips to Reduce Halogen Heater Running Costs
Halogen heaters can be affordable when used wisely, but if you run them for long hours, the electricity bill may surprise you. Luckily, there are several ways you can minimize running costs while still staying warm and comfortable.
- Use Timers and Thermostats
- Many modern halogen heaters come with built-in timers and thermostats. Instead of keeping the heater on for hours, you can set it to turn off automatically after 30 minutes or an hour.
- A thermostat helps regulate temperature by switching the heater off once the desired warmth is reached. Without one, you risk wasting energy by overheating the room.
- Positioning for Maximum Efficiency
- Halogen heaters work by radiating heat directly, so their placement matters. Position the heater in front of you rather than across the room.
- In small rooms, place it near walls to prevent heat loss. For outdoor use, angle it to cover seating areas rather than leaving it facing open air.
- Combine with Other Heating Methods
- Instead of relying on halogen heaters alone, use them as supplemental heating. For example, keep central heating at a lower temperature and use a halogen heater only when you’re sitting still in one place.
- Combining a halogen heater with insulation upgrades (like draft stoppers, thermal curtains, and rugs) ensures the warmth lasts longer without needing extra power.
- Limit Usage Duration
- The golden rule with halogen heaters: use them for short bursts. A quick 15–30 minutes of radiant heat may be enough to warm you without keeping the heater running all night.
- Take Advantage of Off-Peak Rates
- If your electricity supplier offers time-of-use tariffs (cheaper power at night), you can plan your usage during those hours to save money.
In short, the key to saving money is to treat halogen heaters as targeted, short-term heating solutions rather than full-time replacements for central heating.
