1250w Electric Radiators | Traditional-Style British Heating for Rooms Up to 12.5m²

Is 1250w Right for Your Room?

A 1250w output comfortably covers well-insulated rooms of around 12.5m². This typically covers a standard double bedroom, a dining room, or a mid-sized kitchen in a modern UK property. If your room is larger, has high ceilings, solid walls, or significant glazing on a north-facing aspect, stepping up to our 1300w or 1500w categories may give you a more comfortable result. Our Electric Heating Calculator will give you a precise figure based on your room's actual dimensions and insulation, or call our UK team on 0113 239 9919.

DigiLine Double Panel 1250w — The Radiator That Looks Just Like Central Heating

The DigiLine double panel range is designed and manufactured entirely in Britain from steel with a durable powder-coated finish, built to give homeowners, electricians, and property developers the same breadth of radiator choice that plumbers have always had — but running entirely on electricity. If you are replacing a gas central heating system room by room, upgrading from ageing storage heaters, or extending heating into a space that cannot be plumbed, the DigiLine provides the same familiar aesthetic and the same comfortable feeling of warmth — without a single pipe in sight.

Inside the steel body sits a sealed cavity filled with thermal fluid. This fluid is heated by 100% efficient electric elements that warm the entire radiator surface rapidly and uniformly, with no hot spots or cold patches. Central convection fins behind the panels ensure a balanced output of radiant heat — warming surfaces and people directly — and convected heat that circulates warmed air throughout the room. There are no pumps, no moving parts, and nothing to service or drain. The thermal fluid is specifically engineered to resist freezing and internal corrosion, and is 100% recyclable at end of life.

The double panel design includes a particularly intelligent energy management feature: when the room temperature is within 1°C of the programmed set point, only the front panel operates. When the room temperature drops further from target — such as first thing in the morning or after a window has been opened — the rear panel activates as a boost, increasing output automatically until the room recovers, then stepping back to single-panel operation. This avoids the energy waste of running at full power unnecessarily while ensuring the room always reaches temperature when needed.

The precision thermostat maintains room temperature to within ±0.1°C, switching on and off dynamically to minimise electricity use. Open window detection senses a rapid temperature drop and pauses heating until the window is closed. Adaptive start learns your room's specific heat-up characteristics over time and begins heating in advance of your scheduled times — so the room is at the right temperature precisely when you need it, not just when the clock tells the radiator to start. A lockable control panel prevents accidental or unauthorised changes to settings, and the maximum surface temperature can be set at 60°C, 75°C, or 90°C to suit the room's occupants and use case.

For those who want the convenience of remote control, the DigiLine is compatible with an optional Zigbee 3.0 UniPL gateway. Once connected to your router, the free Unisenza Plus app gives full scheduling and temperature control from any smartphone or tablet, along with Amazon Alexa and Google Home voice control integration and multi-room zone management from a single interface — making it one of the most capable WiFi-controlled electric radiators available in a traditional style.

The DigiLine does not include a plug as standard and will need to be hardwired by a qualified electrician, or a plug can be purchased separately and fitted to the cable for plug-in installation. This product is delivered by pallet — please ensure someone is available to receive the delivery. If you are ordering three or more DigiLine units, free pallet delivery applies.

100% Efficient — No Plumbing, No Maintenance

Like every product in our range, the DigiLine 1250w converts all consumed electricity directly into room heat — nothing is wasted. There are no pipes, no boiler connections, and nothing to service year on year. Wall brackets and installation hardware are included.
