Do Infrared Heaters Actually Save You Money? The Honest Answer

Yes, infrared heaters can save you money - but only in the right room, for the right number of hours, and against the right alternative. They primarily transfer heat to people and surfaces through infrared radiation rather than relying mainly on circulating warm air. Used to heat one room for a few hours a day, a well-chosen unit from our infrared heaters range can genuinely cut what you spend on heating. Left running all day to warm an entire house, it almost certainly won't. Here's the honest breakdown, using real UK running-cost figures rather than marketing promises, so you can decide whether infrared heating actually suits the way you use your home.

How Infrared Heaters Actually Use Electricity

Every plug-in electric heater, whatever it looks like, converts electricity into heat at close to 100% efficiency at the point of use - none of the energy is lost up a flue the way it is with a gas boiler. What makes an infrared heater different is how that heat reaches you. Instead of warming the air and waiting for it to circulate, infrared heaters emit radiant heat that warms your skin, clothing and furniture directly, in much the same way sunlight warms you even on a cold day. According to Electrical Safety First's guidance on portable heaters, radiant-style heaters " radiant heaters primarily transfer heat to people and surfaces through infrared radiation rather than heating the room mainly through air circulation" at all, which is why you can feel the warmth almost instantly, even in a draughty space.

This matters for running costs because a fan or convection heater has to warm the whole volume of air in a room - and keep re-warming it every time a door opens - before you feel any benefit. An infrared heater skips that step. It doesn't use less electricity per kilowatt than any other type of electric heater, but it can make targeted heating more practical, particularly when you only need warmth in one occupied area.

It's also worth understanding why electric heating in general carries a reputation for being pricey, since that context shapes every comparison later in this guide. According to the Energy Saving Trust, electricity typically costs around four times as much as gas per unit in the UK. Electric resistance heaters, including infrared heaters, convert almost all of the electricity they consume into heat at the point of use, but a near-perfect conversion rate doesn't cancel out a much higher starting price for the fuel itself. That's the tension at the heart of the "do infrared heaters save money" question, and it's why the honest answer depends so heavily on how and where you use one.

What Really Determines an Infrared Heater's Running Cost

There's no single answer to "how much does an infrared heater cost to run" because the real cost depends on several things working together, not the heater alone.

The starting point for any running-cost calculation is the current electricity unit rate. Under Ofgem's price cap for July to September 2026, a typical UK household on a standard variable tariff pays around 26.11p per kilowatt hour (kWh) for electricity on direct debit, plus a daily standing charge. That rate changes every quarter, so it's worth checking Ofgem's latest figures before you do your own sums.

Using that rate as a guide, here's roughly what different infrared heater outputs cost to run for one hour, assuming the heater is working at full power the whole time:

●        A 400W infrared panel: around 10p per hour

●        A 720W infrared heating panel: around 19p per hour

●        A 1,500W portable infrared heater: around 39p per hour

●        A 2,000W wall-mounted infrared heater: around 52p per hour

●        A 3,000W outdoor patio heater: around 78p per hour

In practice, few heaters run at full output the entire time. A heater fitted with its own thermostat, or paired with a smart plug, will cycle down or switch off once the room reaches your set temperature, which is where the real savings usually come from - not from the technology itself.

Insulation and draught-proofing make a bigger difference to these figures than most people expect. The Energy Saving Trust's guidance on electric heating points out that an insulated, well-controlled home will reduce heating bills whatever type of heater you're using, since less of the warmth you're paying for escapes through gaps, single glazing or an uninsulated loft. A gap under a door or an unlined chimney can undo a good chunk of what a well-sized infrared heater is doing, so it's worth checking the basics before assuming a heater alone is the problem or the solution.

Are Infrared Panel Heaters Cheaper to Run Than Other Electric Heaters?

Watt for watt, an infrared heating panel and a fan heater of the same output cost exactly the same to run, because both are converting electricity to heat at close to 100% efficiency. The difference shows up in how you use them. A fan heater tends to get switched on and left running because the room feels cold until enough air has circulated. An infrared panel heats you and your immediate surroundings within a minute or two, which makes it easier to use in short bursts rather than leaving it on out of habit.

That behavioural difference is genuinely useful in rooms with high ceilings, large windows or solid walls that hold the cold, where warm air escapes or cools quickly. Our infrared heating panels are a good example - a slimline wall or ceiling-mounted panel that delivers steady background warmth to a home office, living room or bedroom without the noise or dust circulation of a fan heater. If you're weighing up infrared heaters panels against oil-filled radiators or fan heaters for a specific room, sizing the wattage to the room (rather than buying the biggest unit available) makes far more difference to your bill than the heater type alone. As a rough guide, a 720W panel used for three hours a day works out at a little under 60p a day at current Ofgem rates - roughly £4 a week - which is a manageable add-on for one room, but would multiply quickly if you tried to heat an entire house the same way.

Infrared Heaters vs Central Heating: Which Can Actually Cost Less?

This is the comparison most people actually want answered, and it deserves an honest one.

Under the same Ofgem price cap period, gas costs around 7.33p per kWh compared with 26.11p per kWh for electricity - roughly a third of the price, unit for unit. That single fact means that heating an entire multi-room home for most of the day is almost always cheaper on gas central heating than on electric infrared heaters, simply because you're paying more per unit of energy, even though the electric heater itself is more efficient at converting that energy into heat.

Where the comparison flips is when you don't need to heat the whole house. Firing up a gas boiler and pumping hot water around every radiator to warm one room you're using for two hours costs more overall than switching on a single infrared heater in that room, because the boiler, pump and pipework are all using energy too. This is particularly true for rooms with no radiator at all - a converted loft, a garden office, a conservatory or an outbuilding - where the alternative to an infrared heater usually isn't cheaper central heating, it's no heating at all.

When Infrared Heating Can Genuinely Save You Money

Infrared heaters tend to pay for themselves, or at least avoid adding much to your bills, in situations like these:

●        Heating a single room you're using for a few hours, such as a home office or a snug, rather than firing up the whole central heating system for one person

●        Warming spaces that have no radiator or gas supply at all, including garden rooms, garages and loft conversions

●        Topping up a cold spot in an otherwise warm home, such as a conservatory or a room over an unheated garage

●        Outdoor and semi-outdoor use, where outdoor infrared heaters give instant warmth on a patio, balcony or hospitality terrace without gas bottles or an open flame

●        Short, high-frequency bursts of heat, such as warming a bathroom for twenty minutes each morning rather than heating it constantly

When Infrared Heating May Not Be the Cheaper Option

It's just as important to be upfront about where infrared heaters are unlikely to save you money:

●        Heating a whole house for most of the day, where gas central heating's lower unit rate wins on cost even with some inefficiency in the system

●        Poorly insulated rooms that need a high-wattage heater running for long stretches just to feel comfortable

●        Homes that already have an efficient, well-zoned central heating system with thermostatic radiator valves, since you'd effectively be paying for two heating systems rather than one

●        As a full-time replacement for a heat pump in a well-insulated home; the Energy Saving Trust notes that heat pumps typically deliver around three times more heat per unit of electricity than a standard resistive heater, which changes the sums considerably over a full heating season

None of this means infrared heating is a bad choice - it means it's a tool for specific jobs, not a blanket replacement for how your whole home is heated.

Choosing the Right Infrared Heater for Your Space

The right choice depends on the room, not just the budget. A small home office needs a different type of heater from a bathroom or an outdoor terrace.

For everyday indoor rooms - bedrooms, living rooms, home offices - a wall or ceiling-mounted panel from our indoor infrared heaters range gives steady, unobtrusive background warmth without taking up floor space. For gardens, patios and outdoor dining or hospitality areas, look for a heater built specifically for outdoor exposure, with a suitable IP rating against rain. If you're after something that works across several room types, our smart heaters range includes app and voice-controlled options that make it easier to run several rooms efficiently without babysitting a dial.

Bathrooms are a slightly different case. A damp room needs a heater rated for that environment, and this is where a mirror-style infrared heater lamp earns its keep - combining a demisting mirror, an LED light and a heating element with the correct IP rating in one wall-mounted fixture, rather than running a separate fan heater on the floor next to water. Renters and anyone in a flat without wall-mounting options, meanwhile, are usually better served by a portable, freestanding infrared heater with a tip-over safety cut-out, since it needs no installation and can move between rooms as required.

How Smart Controls Cut Down Wasted Heating Spend

The single biggest cause of an infrared heater costing more than it should isn't the heater itself - it's a heater running in an empty room, or running at full power long after the room is already warm. A basic heater with no thermostat has no way of knowing when to ease off.

Pairing a heater with a proper thermostat closes that gap. Our Wi-Fi thermostat for infrared heating lets you set a target temperature and a schedule from your phone, and works with Alexa and Google Home if you'd rather just ask for the room to warm up before you get there. The Energy Saving Trust's own advice on heating controls makes the same broader point about any heating system: only heat the rooms you're actually using, and avoid leaving heating running in rooms that are empty, since this is consistently one of the most effective ways to bring down a heating bill without any change to the heater itself.

Staying Safe While You Save

Cutting your heating bill shouldn't come at the cost of safety, and electric heaters - infrared types included - do need to be used sensibly. Electrical Safety First, the UK charity dedicated to reducing home electrical accidents, advises keeping any portable heater at least a metre away from curtains, furniture and other combustible materials, and never using one to dry clothes. They also recommend running a heater from a wall socket rather than an extension lead, placing it on a stable, level surface where it can't be knocked over, and choosing a heater that carries proper UK safety certification (CE or UKCA marking) from a reputable retailer. A heater with a built-in thermal cut-out and, for wall-mounted patio and bathroom models, an appropriate IP rating for damp or outdoor conditions, adds a further layer of protection.

So, Are Infrared Heaters Worth Buying?

The honest answer on infrared heaters is that they're worth buying for the right job: heating one room you're actually using, warming a space with no other heating source, or adding instant outdoor warmth to a patio or terrace. They're less convincing as a way to heat an entire house full-time, where gas central heating's lower unit cost, or a heat pump's higher efficiency, will usually work out cheaper over a full winter. Match the heater to the room, add a thermostat so it isn't running when nobody needs it, and an infrared heater can be a genuinely sensible way to stay warm without heating space you're not using.

If you're still weighing up options, start with the room that's actually cold right now rather than trying to solve every room in the house at once. A single, well-sized infrared heater with a thermostat, used in the space where you spend the most time, is usually where the clearest savings and the most noticeable comfort improvement come from.
