The Truth About Fake Radiators
I've been advising people on heating retrofits for years, and fake radiators come up constantly. People find them online, see the photos, and assume they're getting a traditional cast-iron style heater at a fraction of the cost. It's not quite that simple, but they also aren't useless. Let me explain what they actually are, how they perform, and where they fall apart. A fake radiator is an electric convection or infrared panel heater housed in a decorative casing that mimics a traditional water-filled radiator. The casing might be MDF with a printed ceramic finish, powder-coated steel, or even real stone composite. Inside is a standard electric heating element — usually a PTC ceramic panel or infrared quartz tube — and a basic thermostat. Some higher-end versions include programmable timers and Wi-Fi controllers. The main selling point is aesthetics. You get the look of a period property radiator without running any pipework through your walls. The heating mechanism is where most people misunderstand these things. Despite looking like a water-filled unit, there is no water circulating through them. Water-filled electric heaters exist too — they use a sealed salt or oil core that holds heat longer — but the cheaper fake radiators are almost entirely air-convection based. That means they heat the air directly and push it outward. The decorative fins don't actually improve heat output meaningfully. They're there for visual appeal.
I once had a client who bought three faux Victorian-style radiators for a London townhouse he was converting. No gas line, no mains water connection available. He wanted the original character of the property preserved. The units looked fine on the wall. The problem was the room sizes. Each unit was rated at 1.5kW, which is decent for a small bedroom but inadequate for the two larger reception rooms he'd planned them for. The thermostats kept cycling on and off because the sensors were built into thin plastic housings on the front of the unit. In practice, the room never reached the set temperature, and the electricity bill was noticeable. I ended up recommending he supplement them with a single proper oil-filled electric radiator in the biggest room and use the fake ones only in the smaller spaces where the aesthetics mattered more than raw output. Here's something beginners miss. The wattage rating on these units is often misleading. A 2000W fake radiator won't heat a room the same way a 2000W conventional panel heater will, because the airflow path is different. The decorative casing restricts air movement around the heating element. You lose maybe fifteen to twenty percent of effective output compared to a standard convector heater at the same wattage. Factor that into your room sizing from the start instead of assuming one-to-one equivalence. Installation basics. These units are wall-mounted, typically using two or four screws through the backplate into wall anchors. Most weigh between four and eight kilograms empty, though the heavier stone-composite versions can push toward twelve. Make sure you're fixing into studs or using appropriate rawl plugs for the wall type. Drywall alone won't hold them safely if the unit is more than six kilos. Plug them into a dedicated socket or hardwire if you're doing a permanent installation. Never daisy-chain multiple units onto a single extension lead — that's a fire risk that shows up in surveys more often than you'd think.
Controls and efficiency. The cheapest models come with a basic dial thermostat that has a ten-degree swing. You set it to twenty degrees and it won't cut in until the room hits ten, then it runs full bore until forty. That's useless for comfort. Spend the extra money on a model with a digital thermostat and a programmable schedule, or just pair any unit with a smart plug and an external room sensor if you're on a tight budget. Smart plugs are about fifteen pounds and they solve the cycling problem entirely. Where these actually work well. Rental properties where you can't run pipes. Period buildings with listed status preventing structural changes. Guest rooms used intermittently where you don't want to fire up a central system. Bathroom auxiliary heat where a mirror heater or towel rail isn't enough. Second living spaces that stay closed off most of the time. In those scenarios, fake radiators are a perfectly reasonable solution. They're not revolutionary by any stretch, but they fill a real gap. Where they fail. Main living areas in poorly insulated homes. Any space where you need consistent background heat rather than boosting. Old buildings with draughts — these units move air around, so they'll just circulate cold air from gaps under doors and around windows faster. If your problem is insulation, a heater of any kind, fake or real, is going to feel inadequate because it's fighting the heat loss directly. Address the insulation first or budget for a significantly higher wattage than you'd normally need.

A specific edge case. I dealt with a customer who installed a fake radiator directly beneath a large sash window in an older property with single glazing. The unit was fine in terms of output, but the cold air dropping from the window created a downdraft that the convection heater was working against constantly. The thermostat kept running the element at full power and the room still felt chilly. I moved the unit to an interior wall and added a simple thermal curtain on the window side. Temperature stability improved immediately without touching the heater itself. Placement matters more than people realize with these units. The market for these has grown because people want period aesthetics in modern flats and renovations. The technology inside hasn't changed much — it's still resistive electric heating in most cases. What has improved is the casing quality. Earlier versions had visible seams and cheap-looking prints. Newer units from decent manufacturers use layered finishes, realistic textures, and better hardware for mounting. The difference between a fifty-pound unit and a three-hundred-pound one is mostly in the casing, not the heating element. Don't overspend on the looks if the wattage and controls are wrong for your room. If you're comparing fake radiators to alternatives, a standard oil-filled electric radiator will heat a room faster and more evenly. A portable convector is cheaper upfront. A heat pump is the right long-term answer if you're doing a full renovation. Fake radiators sit in the middle — better than a bare panel if aesthetics matter, worse than proper infrastructure if you're trying to solve a fundamental heating problem. Know which category your situation falls into before buying anything.
