NEYRA is a low‑consumption fluid filled electric radiator in injected aluminium, designed to provide lasting comfort and optimised energy use in everyday home heating. Its high‑thermal‑inertia heat transfer fluid stores heat and releases it gradually, helping to reduce operating cycles while maintaining a stable, comfortable room temperature.
What is the NEYRA fluid filled radiator?
NEYRA is an electric radiator with thermal fluid and injected aluminium structure, engineered to deliver lasting comfort and optimal energy efficiency. As part of HJM’s range of fluid filled radiators, NEYRA is designed to provide long‑lasting, even warmth and easy temperature control in domestic spaces. Its balance of performance, robustness and simple controls makes it a practical choice for everyday heating in bedrooms, living rooms and home offices.
High‑inertia heat transfer fluid
At the core of NEYRA is a high thermal inertia heat transfer fluid that retains heat and releases it gradually into the room. This high‑inertia behaviour reduces the number of on/off cycles required to maintain the desired temperature, helping to optimise energy consumption over time.
The high‑quality thermal fluid ensures homogeneous and constant heat diffusion along the radiator, creating a pleasant, consistent level of warmth without cold spots. This makes NEYRA particularly suitable for spaces where steady, gentle heating is preferred throughout the day.
Injected aluminium body for strength and efficiency
NEYRA’s injected aluminium body provides strength, resistance to corrosion and long‑term durability. Aluminium is an excellent heat conductor, supporting efficient transfer of energy from the fluid to the surrounding air and contributing to the radiator’s overall efficiency.
Each unit is supplied with wall mounting brackets (+2.5 cm) and includes a double lateral fairing, ensuring a clean, integrated appearance on the wall. NEYRA is rated IP24, Class I, which allows safe installation in a wide variety of domestic environments.
Digital programmable thermostat and operating modes
NEYRA features an easily programmable digital thermostat that supports 24/7 scheduling with one free program and two pre‑recorded programs. This enables users to match heating profiles to their daily and weekly routines, heating rooms only when they are in use and reducing unnecessary electricity consumption.
The control logic supports multiple operating modes, including comfort, night, antifreezing, boost, auto, manual and away, giving flexibility to adapt the radiator’s behaviour to different times of day and seasons. This helps households balance comfort and cost throughout the heating season.
Safety and comfort functions
To enhance safety and ensure reliable operation, NEYRA integrates open‑window detection, adaptive temperature control, keyboard lock and a safety thermal limiter. Open‑window detection reacts to sudden drops in temperature, helping to avoid wasting energy when a window is left open.
Adaptive temperature control refines how the radiator reaches and maintains the set temperature, reducing overshoots and improving comfort. The keyboard lock prevents accidental changes to settings, while the safety thermal limiter protects the unit from overheating during long‑term use.
