RadiWarm HE4140 1.625 kW Low-Height Electric Radiator

Reliable Heating for Conservatories and Low Walls

The RadiWarm HE4140 is a compact, low-height electric radiator designed to provide efficient, comfortable heating where space is limited. At just 400 mm high and 1400 mm wide, it’s ideal for conservatories, bay windows, and low walls — delivering full heating performance in a sleek, unobtrusive design.

True Wet-System Warmth Without Plumbing

Each RadiWarm unit is pre-filled with treated water and fully sealed, producing a natural, radiant heat without the need for plumbing or maintenance. The internal micro-boiler circulates the water to replicate the same gentle warmth as a traditional wet central heating system, powered entirely by electricity.

Smart Temperature Control

The HE4140 works with the RadiWarm RFC wireless controller, offering 7-day programming, adaptive start, and frost protection. Once set, it maintains your chosen temperature efficiently while keeping running costs low.

Quick Installation and Maintenance-Free Design

Fitted with sturdy wall brackets and rated IP44 for bathroom safety, the radiator installs quickly and operates quietly. Simply plug into a 230 V socket or spur connection for reliable, long-lasting heat with no servicing required.

Built in Britain to Lot 20 Standards

Handmade in the UK and fully Lot 20 compliant, the RadiWarm HE4140 offers dependable, energy-efficient heating backed by a 2-year manufacturer’s warranty.
