Cali Sense Eco design features and performance compared to storage heaters

Electric Radiators eco-design certifications and energy performance

Most electric radiators on the market in the UK have a basic CE, the Cali Sense is NF Performance *** + fully compliant with the new UK EcoDesign 2018 lot 20 directive, and accredited to NF Energy Performance Cat C Certification. This is indisputably one of the most stringent quality control certifications in the world and is indisputable evidence of the superior quality and Energy Efficiency of our smart radiator compared to all other competitor systems available online.

NF certification, Mark of compliance, covering aspects such as safety, quality, usage ability and electric heater Energy performance.  Is based on tangible elements: certification rules that are defined with consumers and businesses, tests, manufacturing plant inspections, customer satisfaction surveys, mystery shoppers, and so on. Even after obtaining NF certification, the product, and its manufacturing sites are continuously audited to ensure a consistent level of quality is maintained throughout the production process, offering consumers the guarantee of a rigorously tested quality control procedure.

This means that the Cali Sense has been tested by VERITAS + LCIE  an independent body on safety but also in performance and energy efficiency. So, unlike other companies selling products online that just talk, we prove our performance by independent lab testing.

Theirs is mainly a self-declaration, in most cases, there is no mention to an independent lab test of their products.  To obtain an NF 3*** oeil certification there are quite a lot of different tests a product needs to pass. The following are only to name a few:


NF performance *** testing includes a few endurance tests that demonstrate the quality of the product over time like an ageing test of resistance is performed

Quality of Temperature control

Characterised by the drift in load and temperature amplitude compliance with the requirements of the LCIE NF Performance specifications require that the electric heater is regulated by a so-called PID regulation: Proportional Integral Derivative.

In the case of the Cali Sense electric radiator, this regulation has been the subject of a very fine adjustment in a bi-climatic chamber specific to the product and adapted to each power. As a result, the Cali Sense benefits from a performance in regulation 2 to 3 times better than the current most demanding standard.

Dynamic Efficiency technology

Some online resellers claim their radiators can achieve, have an accuracy of +-0,2°C.  This is obtained by amplitude. So, this for Intelli Heat represents an amplitude of 0.4K, therefore, our Cali Sense is 4 times better.


The Cali Sense is equipped with the V27 technology and without any prior adjustment, the radiator is in a learning mode to understand and memorize the behaviour of the occupant: periods of absence, presence. The initial learning phase is 7 days minimum but this learning is perpetual, it repeats week after week to understand and optimize.
