The ambition of this project is therefore to develop and market a new heat emitter design that will reduce energy consumption for heating residential and commercial buildings, both new construction and renovation, by 20%. It will provide thermal comfort superior to the best systems currently available on the market and will enable installations to achieve high overall efficiencies thanks to its greater reactivity and low temperature operation. It will also be advantageous to couple it with production systems such as heat pumps or solar collectors. This original transmitter has, among other features, the following features: its constituent materials are commonly used in construction promoting rapid commercialization of the system. They are environmentally neutral, are quick and easy to install compared to conventional floor heating systems, can vary eight times faster, is three times smaller in size, weighs six times less and can work with less hot water than light floor heating systems currently on the market, has a higher maximum power and is better distributed. A first spin off grant was requested from the Walloon Region in order to carry out the additional research needed to move from the prototype to an industrialisable product and to carry out a more systematic market study. It is intended to create technological and economic added value for Walloon companies in the sector and, more broadly, for the energy and housing policy of our region. This project is based on a strong partnership with manufacturers and structures d´accompagnement. The protection of intellectual property rights has been taken into account by prior art searches which have made it possible to verify the novelty of the invention; a patent application has been filed and will make it possible to protect economic exploitation.
