Electrorad HHR340 Thermastore HHR White 3400W High Heat Retention Storage Heater (1140mm wide) with TFT Screen & WiFi Control

Electrorad HHR340 Description

The Electrorad Thermastore HHR340 is an intelligent highly efficient white high heat retention (HHR) storage heater designed to provide controllable, cost-effective warmth throughout the day and night.

Ratings - storage input: 3400W | storage output: 1487W | boost output: 1275W

Designed specifically for use with Economy7 or other off-peak tariffs, the HHR340 uses advanced ceramic core technology and intelligent, adaptive charging to maximize cost savings. Delivers up to 40% lower running costs than standard electric radiators.

Unlike traditional storage heaters that "leak" heat, this Lot 20 compliant unit engineered with advanced insulation and intelligent heat management, it retains over 50% of its stored heat for 16 hours after charging, ensuring warm, comfortable rooms whenever you need them throughout the day.

Built-in algorithms monitor the room temperature and learn your heating patterns, automatically calculating and taking only the precise amount of off-peak charge needed for the next day's heating.

Integrated Direct Boost Element: a powerful 1275W direct element for instant heat delivery when the stored heat is insufficient or an immediate temperature boost is required.

Operates from a single fused connection unit (requires a dual-rate meter), simplifying installation and wiring compared to traditional dual-fed storage heaters.

Features a large, high-resolution TFT display for intuitive weekly and daily programming, temperature recording, and energy consumption monitoring.

Includes Open Window Detection (pauses heating when a sudden drop in temperature is detected) and Adaptive Start (learns the best time to switch on for optimal energy savings).

Smart App Control (Optional): when paired with the optional MultiLink USBGATEWAY WiFi hub, users enjoy remote control, voice control (Alexa/Google Home), and Geolocation functions to manage heating from anywhere.

Fully complies with modern European energy efficiency regulations, contributing to an improved Energy Performance Certificate (EPC) rating for the property.
