AUDE is a low‑consumption fluid filled electric radiator in injected aluminium, designed to deliver lasting comfort and optimal energy efficiency in everyday home heating. Its high‑thermal‑inertia heat transfer fluid retains heat and releases it gradually, reducing operating cycles and helping to optimise electricity use while maintaining a stable, comfortable room temperature.
What is the AUDE fluid filled radiator?
AUDE is an electric radiator with thermal fluid and injected aluminium body, engineered to offer lasting comfort and optimal energy efficiency. It belongs to HJM’s range of fluid filled radiators, which are designed to deliver long‑lasting, even warmth and effortless temperature control in domestic spaces. Thanks to its robust construction and high‑quality fluid, AUDE is a reliable solution for everyday use in living rooms, bedrooms and home offices.
High thermal inertia fluid for lasting warmth
At the heart of AUDE is a high thermal inertia heat transfer fluid that stores heat and releases it gradually over time. This high‑inertia behaviour reduces the number of on/off cycles needed to keep the room at the desired temperature, helping to optimise energy use while maintaining a consistent level of comfort.
The high‑quality thermal fluid ensures homogeneous and constant heat diffusion across the radiator surface, creating a pleasant atmosphere without cold spots. This makes AUDE particularly suitable for spaces where steady, gentle warmth is preferred over short bursts of intense heating.
Injected aluminium body: strength and durability
AUDE’s injected aluminium structure gives the radiator excellent strength, resistance to corrosion and long‑term durability. Aluminium is an effective heat conductor, helping to improve the efficiency of heat transfer from the fluid to the room air. Over time, this robust design helps the radiator maintain both its performance and its appearance, even with daily use during the heating season.
The radiator is supplied with wall mounting brackets (+2.5 cm) and features a double lateral fairing, contributing to a clean, integrated look once installed. AUDE offers IP24, Class I protection, making it suitable for a wide range of domestic environments.
Easy programmable digital thermostat and operating modes
AUDE includes an easily programmable digital thermostat that supports 24/7 scheduling with one free program and two pre‑recorded programs. This allows users to tailor heating to their daily and weekly routines, warming rooms only when needed and reducing unnecessary energy consumption.
The control system offers several operating modes, such as comfort, night, antifreezing, boost, auto, manual and away, so you can adjust the radiator’s behaviour to different situations and seasons. This flexibility makes it easier to balance comfort and efficiency throughout the year.
Safety and comfort features
To enhance safety and user peace of mind, AUDE integrates open‑window detection, adaptive temperature control, keyboard lock and a safety thermal limiter. Open‑window detection helps prevent energy waste by reacting to sudden drops in temperature, while adaptive temperature control improves the accuracy of room temperature regulation.
The keyboard lock prevents accidental changes to the settings, and the safety thermal limiter protects the unit against overheating, contributing to safe long‑term operation in residential spaces.
