RadiWarm HE4100 Low-Height Electric Radiator
Compact Heating for Conservatories and Low Walls
The RadiWarm HE4100 is a low-height, water-filled electric radiator designed for reliable and efficient heating where wall space is limited. At only 400 mm high, it’s ideal for conservatories, bay windows, and dwarf walls — providing full heating performance in a compact footprint.
True Wet-System Warmth Without Plumbing
Each radiator is pre-filled with specially treated water and permanently sealed, requiring no plumbing, bleeding, or maintenance. The built-in micro-boiler produces a smooth, radiant heat output that closely replicates the feel of traditional wet central heating, without the need for pipework or a gas connection.
Smart, Efficient Control
The HE4100 connects wirelessly to the RadiWarm RFC controller, offering 7-day programmable scheduling, adaptive start, frost protection, and eco-saving functionality. Once installed, it maintains a consistent room temperature while optimising energy use.
Easy Installation & Safe Operation
Installation is simple — mount the radiator on the supplied wall brackets and plug it into a standard 230 V socket or spur connection. Built to IP44 standards, it’s suitable for use in Zone 2 and Zone 3 bathroom areas. The sealed, maintenance-free design ensures long-term reliability with zero ongoing servicing.
Built in Britain to Lot 20 Standards
Manufactured in the UK, the RadiWarm HE4100 meets Lot 20 energy efficiency standards and is backed by a 2-year manufacturer’s warranty for complete peace of mind.
