2000w Electric Radiators | High-Output Heating for Rooms Up to 20m²

Is 2000w Right for Your Room?

A 2000w output suits well-insulated rooms of approximately 20m² — a spacious living room in a modern new-build, a large double bedroom in a well-maintained Victorian terrace with upgraded insulation, or any room where the 1500w or 1600w categories fall slightly short. In rooms with poor insulation, very high ceilings, or large single-glazed windows, you may find our 2500w category a better fit. Our Electric Heating Calculator provides a personalised recommendation based on your specific room dimensions and conditions. Our team is also happy to assist — call 0113 239 9919, Monday to Friday 9am–5pm.

Choosing the Right 2000w Product: A Guide Across the Range

With nine distinct product technologies available at 2000w, this category rewards careful comparison. The right product depends on your room's wall dimensions, whether you want WiFi, the heat delivery style you prefer, your budget, and whether you are a homeowner, landlord, or developer.

Aeroflow AF05E 2000w — Classic German Horizontal Format

The Aeroflow AF05E is a classically proportioned German electric radiator — 980mm wide and 615mm tall — that delivers 2000w through the same German fireclay heat plate technology common to the entire Aeroflow range. Its refractory block assembly of non-porous fireclay heat plates retains and radiates heat for well over 30 minutes after the element cycles off, providing a steady, comfortable room temperature with none of the sharp cycles of a basic panel heater. Built-in 2.4GHz WiFi connects directly to your router — no gateway required — and the Smart RM app provides full remote scheduling and control via Android or iOS. Compatible with Amazon Alexa. The ±0.2°C thermostat, 7-day programming, open window detection, and adaptive start are all standard. Supplied in white RAL 9010, available in any RAL colour on request. CE and GS certified. 30-year body guarantee, 2-year thermostat warranty. Pallet delivery. Dimensions: 980×90×615mm, heats up to 20m². Also available as part of the Aeroflow 650w–2500w range.

Aeroflow AF14E 2000w — Ultra-Wide Low-Profile German Format

The Aeroflow AF14E delivers the same 2000w output and German fireclay quality as the AF05E, but in a strikingly different format — 1580mm wide and just 325mm tall. This makes the AF14E the right choice for rooms where horizontal wall space is plentiful but height is limited: under low windows, across the width of a bay window alcove, beneath a wide windowsill, or along a low wall between kitchen units. The wide, shallow profile creates a different visual aesthetic to a standard radiator and can work particularly well in contemporary or open-plan interiors. All Aeroflow performance, control, and warranty specifications apply equally to the AF14E as to the AF05E. Pallet delivery — please note that this product qualifies for additional delivery surcharges in some postcode areas; see our Delivery Information page. Dimensions: 1580×90×325mm, heats up to 20m².

Vanguard VA2000W 2000w — Aluminium Ceramic Core with Built-In WiFi

The Vanguard VA2000W is one of the most popular radiators in the entire Electric Radiator Shop range, combining aluminium construction with a ceramic core for rapid, responsive heating and excellent heat retention between element cycles. The built-in WiFi connects via an optional USB gateway for full app control and compatibility with Amazon Alexa and Google Home. The ±0.1°C precision thermostat, 7-day programming with nine preset modes, open window detection, adaptive start, silent Triac switching, energy monitor, and Lot 20 compliance are all standard. Wall-mounted on a standard 13A supply. Dimensions: 895×95×575mm, heats up to 20m². Also available without built-in WiFi as the Vanguard VA2000, and as part of the Vanguard 750w–2000w range.

DigiLine DE50DX125Z 2000w — British-Made Double Panel, Standard Width

The DigiLine DE50DX125Z is a British-designed and manufactured double panel traditional-style radiator at 1250mm wide and 500mm tall — large, imposing, and visually indistinguishable from a plumbed central heating radiator. Thermal fluid heated by 100% efficient electric elements delivers both radiant and convected heat, while the intelligent dual-panel control system uses the rear panel only when the room is more than 1°C from the target temperature — conserving energy by running only what the room needs. The ±0.1°C thermostat, open window detection, adaptive start, and lockable control panel are standard. Optional Zigbee 3.0 WiFi via the UniPL gateway enables Unisenza Plus app control and Alexa/Google Home compatibility. No pumps, no maintenance. Pallet delivery. Dimensions: 1250×80×500mm, heats up to 20m². Also available as part of the DigiLine double panel range.

DigiLine DE30DX200Z 2000w — British-Made Double Panel, Extra-Wide Low Profile

The DigiLine DE30DX200Z is a genuinely unusual product — 2000mm wide and just 300mm tall, it is the widest and lowest-profile radiator in the entire Electric Radiator Shop range. Designed for rooms where vertical wall space is severely limited — beneath particularly low windowsills, under fitted furniture, or along a low dado wall — it delivers the same full British-made DigiLine quality and intelligent dual-panel control in a format that simply cannot be replicated by any other product in the range. Please note this product qualifies for additional delivery surcharges in some postcode areas. Pallet delivery. Dimensions: 2000×80×300mm, heats up to 20m².

Accorto 2000w — Ceramic Core with Occupancy Sensing and Landlord Lock

The Accorto 2000w adds integrated occupancy sensing — via a built-in microwave sensor — and a landlord lock function to the ceramic core heating technology common across the Accorto range. The radiator detects whether the room is occupied and automatically reduces to a setback temperature when the room is empty, cutting energy use in rooms with irregular occupancy patterns without requiring manual intervention. The landlord lock prevents tenants from overriding the heating programme — particularly valuable in HMOs, furnished lets, student accommodation, and managed properties. The ±0.1°C thermostat, comfort/economy/frost modes, and open window detection are all included. Lot 20 compliant. Dimensions: 741×90×570mm, heats up to 20m². Also available as part of the Accorto 700w–2000w range.

ThermaStore HHR 3400w — Economy 7 Storage Heating for 20m² Rooms

The ThermaStore HHR 3400w is the largest model in the ThermaStore HHR range and the only product in this category rated for a 20m² room output via Economy 7 or Economy 10 off-peak charging. Its 3400w ceramic core charges overnight on a cheaper off-peak electricity tariff, then releases stored heat steadily throughout the following day via a fan-assisted output — providing equivalent room coverage to a 2000w direct-acting radiator while reducing per-unit energy costs. Independent testing indicates savings of up to 40% compared with standard electric radiators and up to 20% compared with older storage heater technology when used on a qualifying tariff. Adaptive charging, geolocation, open window detection, boost element, BRE SAP database listing, and optional app/voice control are all included. Installation must be carried out by a qualified electrician. Pallet delivery. Dimensions: 1140×185×743mm, heats up to 20m². Also available as part of the ThermaStore HHR 1650w–3400w range.

Smartpanel 2000w — Precision Programmable Panel Heater

The Smartpanel 2000w delivers the Smartpanel range's outstanding thermostat precision (±0.1°C), energy monitoring, adaptive start, and 7-day programming with nine factory presets plus four customisable settings in the highest output the range offers. At just 80mm deep, it remains one of the slimmest 2000w radiators available. No WiFi, but unmatched temperature control accuracy at a highly competitive price for buyers who want precision without paying a premium for app connectivity. Powder-coated steel in RAL 9016, safe-touch surface. 13A plug-in supply. Dimensions: 825×80×450mm, heats up to 20m². Also available as part of the Smartpanel 600w–2000w range.

Designer Panel 2000w — Built-In WiFi, Ultra-Slim

The Designer Panel 2000w brings built-in WiFi, rapid aluminium element heating, and a 90mm slim profile together at one of the most accessible price points for a WiFi-enabled 2000w radiator. Comfortable/economy/frost modes, open window detection, adaptive start, and 7-day programming are all standard. No external gateway required. Plug-in 13A or hardwired. Dimensions: 815×90×430mm, heats up to 20m². Also available as part of the Designer Panel 1000w–2000w range.

Contract Panel 2000w — Built-In WiFi at Entry-Level Price

The Contract Panel 2000w is the most affordably priced WiFi-enabled 2000w radiator in the range — ideal for landlords, developers, and multi-room projects where budget discipline matters. At 65mm slim — the thinnest product in this category — it is easy to install in tight spaces. Built-in WiFi, aluminium element, comfort/economy/frost modes, open window detection, and adaptive start all included. Plug-in 13A or hardwired. Dimensions: 815×65×430mm, heats up to 20m². Also available as part of the Contract Panel 500w–2000w range.

Which 2000w Product Is Right for You?

For the finest heating quality and the longest guarantee, the Aeroflow AF05E or AF14E (depending on your wall shape) delivers German fireclay performance with 30-year assurance. For the best all-round premium radiator with WiFi and proven popularity, the Vanguard VA2000W is the standout aluminium ceramic choice. For a traditional radiator look with British manufacturing and intelligent dual-panel efficiency, choose between the DigiLine DE50DX125Z (standard width) or the DE30DX200Z (ultra-wide low profile). For occupancy sensing and landlord lock in a rental or managed property, the Accorto 2000w is unmatched. For the tightest possible temperature control without WiFi at mid-range price, the Smartpanel 2000w excels. For built-in WiFi at the lowest price point, choose the Contract Panel (slimmest) or the Designer Panel (slightly more refined finish). And for Economy 7 tariff users, the ThermaStore HHR 3400w is the only product in this category that meaningfully reduces your per-unit heating cost.
