Are electric heaters cheaper to run than central heating? Experts answer this hotly debated question so you can save money without worry

Electric heaters are a common necessity in most homes, to boost warmth and direct heat when needed.

But, with winter weather setting in, experts warn that in most instances they aren't cheaper to run than central heating – and certainly won't save you money long-term.

Here, our HVAC pros break down how much it costs to run an electric heater, the benefits of them, and why using one might not be the best option for you.

Are electric heaters cheaper to run than central heating?

While electric heaters are a brilliant, interim solution to add warmth to a room, they aren't a cost-effective fix long-term, even in comparison to leaving the heating on all day.

Andy Shu, HVAC specialist at ZapFixers explains, 'No, electric heaters are generally not cheaper to run than central heating unless you're heating a small, isolated space for a short period.

'Central heating, which typically uses gas or heat pumps, is more energy-efficient and cost-effective for heating an entire home.'

To break down the costs, Shu advises that the average cost of an electric heater is roughly between $0.15-$0.20 per kWh depending on local electricity rates. This means running a 1,500W heater for five hours would cost about $1.13 a day.

To compare the two home heating types, the average cost of central heating is around $0.05-$0.08 per kWh for gas heating, meaning heating a 1,500 square foot home costs around $1-$1.50 a day – making natural gas the cheapest type of heating to run.

'Gas is significantly cheaper than electricity per unit of energy,' says Shu. 'And, central heating systems distribute heat efficiently across the home, whereas electric heaters only warm a single space.'

Drawbacks of using electric heaters

As well as being more expensive to run long-term in comparison with central heating, if you're wondering if you can leave a space heater on overnight, experts warn that prolonged use increases the risk of overheating, burns, and even fires. Instead, to negate one of the most common fire risks in your home, keep heaters approximately three feet away from any flammable sources, and always turn them off when heading to bed or leaving the house.

Francis Kasper, certified HVAC technician with Chill Brothers Texas, also notes that electric heaters 'may create dry air or hot spots if not placed correctly.'

When to use electric heaters

That being said, electric heaters are undoubtedly an efficient solution to temporarily heat up smaller spaces, particularly if you're clued up on the best types of space heaters.

Sophie Edwards, a News Writer here at Homes & Gardens who grew up in the U.S., says, 'My father's apartment growing up had electric heaters that you could turn on in just one room,' which can help to cut energy bills where applicable, by avoiding heating an entire home. As Colin Matei, owner and president of Clean Air Heating & Cooling says, 'This targeted approach reduces overall utility costs while providing comfort in specific spaces.'

Lucas Moncado, co-owner and master electrician at Brooks Electrical Solutions also points out that electric heaters may be a good match for eco houses which harness the power of solar panels. 'In instances where I've worked with renewable energy systems, like solar-powered homes, an electric heater can be an excellent match, offset by the energy savings of solar panels.'

Furthermore, electric heaters can also be useful to warm up spaces when experiencing problems with your central heating, while awaiting professional help.

How to get the most out of your electric heater

Electric heaters can be expensive, so, when using one in your bedroom ideas or living room ideas, how can you make the most out of it? HVAC specialist Shu shares his tips:

• Use a thermostat-controlled heater to prevent unnecessary overheating and energy waste
• Supplement it with insulation by ensuring windows and doors are sealed to retain heat
• Try zone heating by closing off rooms that don't need heating to focus warmth where needed
• Set a timer and run the heater only when you're present in the room
• Choose energy-efficient models by looking for ceramic or infrared heaters, such as the Lasko Oscillating Digital Ceramic Tower Heater available at Amazon for better performance
