750w Electric Radiators | Aluminium, WiFi & Traditional-Style Heating for Rooms Up to 7.5m²
Our 750w electric radiators cover one of the most popular output levels for small to medium-sized rooms — typically those up to around 7.5m² in well-insulated UK homes. This category includes bedrooms, home offices, hallways, kitchens, and landings — any space where consistent, controllable warmth is needed without the expense of a higher-output unit.
What makes the 750w range particularly versatile is the choice of heating technology available. If you prefer a modern, slimline aluminium electric radiator with smart controls, the Vanguard range — available in a standard programmable version or a fully WiFi-controlled model — delivers rapid heat-up, ceramic core heat retention, and Lot 20-compliant efficiency in a clean, contemporary finish. If you are replacing a central heating system or want a radiator that looks exactly like a traditional plumbed radiator, the DigiLine double panel steel radiator — designed and manufactured in Britain — provides the same familiar look and feel, filled with thermal fluid for even, comfortable warmth throughout the room.

A 750w electric radiator is suitable for well-insulated rooms of approximately 7–7.5m². This covers a compact single bedroom, a typical home office, a hallway, a landing, or a kitchen in a modern or recently renovated property. If your room has high ceilings, large windows, poor insulation, or sits on an exposed external wall, a higher output may be more appropriate — our Electric Heating Calculator will give you a more accurate figure in seconds, or call our UK team on 0113 239 9919.
Vanguard 750w — Aluminium, Ceramic Core & Smart Controls
The Vanguard range from Electrorad is a continental-style aluminium electric radiator with a ceramic core at its heart. The aluminium body heats up rapidly and distributes warmth evenly, while the ceramic core continues to emit heat even after the element has switched off — reducing on/off cycling and keeping running costs in check. Both the standard Vanguard and the Vanguard WiFi at 750w include a precision thermostat accurate to ±0.1°C, a 7-day programmable timer with 9 preset programmes, open window detection, adaptive start, an energy consumption monitor, and silent Triac-controlled operation. The controls sit discreetly at the top of the unit to maintain its clean aesthetic — ideal for living rooms, bedrooms, and home offices.
The Vanguard WiFi model adds app control from anywhere in the world via the free Electrorad app, full Amazon Alexa and Google Home compatibility, and geolocation automation — so your heating turns on as you approach home and off as you leave. WiFi is enabled via an optional lightweight USB gateway (smartbox), and the signal can hop between radiators to extend range throughout larger properties. Both models are Lot 20 Ecodesign compliant and achieve the highest available seasonal efficiency rating.
DigiLine Double Panel 750w — Traditional Style, Modern Intelligence
The DigiLine double panel at 750w is ideal for customers who want an electric radiator that is indistinguishable from a traditional plumbed central heating radiator — the same steel construction, the same profile, and the same feel of warmth. Designed and manufactured in Britain, the DigiLine is filled with thermal fluid that heats the entire surface area evenly without any pumps or moving parts. The precision thermostat is accurate to ±0.1°C, and the double panel design features smart control: when the room is within 1°C of the target temperature, only the front panel runs; when more warmth is needed, the rear panel activates as a boost — saving energy without sacrificing comfort. Open window detection, adaptive start, a lockable control panel, and a maximum selectable surface temperature of 60°C, 75°C, or 90°C are all included as standard.
For those who want wireless control, the DigiLine is compatible with an optional Zigbee 3.0 UniPL gateway, which links with your router to provide full app control (Unisenza Plus app), Amazon Alexa and Google Home integration, and multi-zone scheduling from a single interface. The thermal fluid is 100% recyclable, cannot freeze, and is designed to prevent internal corrosion — meaning no maintenance and an extremely long service life. DigiLine radiators are delivered by pallet; please ensure someone is available to receive the delivery.
100% Efficient — No Plumbing, No Maintenance
Every product in this category converts all consumed electricity directly into room heat. There are no pipes, no boiler connections, and nothing to service. Wall brackets and installation hardware are included with all models.
