THE ENERGY OF TOMORROW
NOW AT HOME
Natural and renewable thermal energy is available everywhere in large quantities.
We use the Earth to store it, water to transport it and the sun to heat you.
WATINYOO, the energy is in you !
Our values
WATINYOOwas born in 2017 with a clear project: To offer owners and operators a different approach to energy management based on the use of local, natural, immediately available resources and not expensive and centralized infrastructure.
By integrating the end user into the production process, his relationship with energy is profoundly changed and a more virtuous behavior is induced.
The WATINYOOconcept Includes all the elements of thermal energy production (heating, cooling, ECS), but also the electrical energy needed for this production (primary energy).
Our offer
WATINYOOuses soil to produce and store heat by installing a water loop as a means of transport and distribution.
By regulating the temperature of the loop using geothermal energy and additional sensors (fatal heat, grey water, solar), WATINYOOsystems achieve an optimum entry temperature. The heat pumps (HP) connected to the loop thus benefit from a stable temperature throughout the year, allowing them to reach (or even exceed) their maximum Coefficient of Performance (COP).
Additional heat sources (always free and natural) make it possible to supplement the thermal kWh requirements.
COMPARATIVE ENERGY PERFORMANCE
- Heating Oil or Gas + DHW electric: COP 2.5
- Aerothermal heat pump: COP 4.5
- WATINYOO Basic installation : COP 7.3
- Complete WATINYOOinstallation : COP 14,3
WATINYOOuses THE EARTH to store heat, produce it or dissipate it by means of a large diameter water loop (Ø 225 mm) installed 1.50 m deep.
Geothermal baskets are used to regulate the temperature of the loop.
The system thus benefits from a high thermal stability throughout the year in order to supply the HP connected to the system.
THE WATER is a naturally heat transfer element. To prevent any risk of pollution in case of accidental leakage, WATINYOOdoes not add any additives in the water contained in the loop.
HP draw from water the energy necessary for their optimal functioning.
The SUNis the main source of natural energy. WATINYOOrecovers it from capture points (eg PV/T hybrid solar panels) to provide additional energy to the whole.
PV/T panels cover the electrical energy needs necessary for the operation of the equipment.
ANOTHER VISION OF ENERGY
MUTUALIZATION OF Renewable energies
WATINYOO uses renewable energy, naturally available and abundant for better efficiency. We pool resources to optimize their efficiency. We use robust and mastered technologies for a better durability of the installation.
It is often said that the cheapest energy is the one we do not consume… our vision of efficiency also includes cost control.
First of all, the installation costs; each project is the subject of a detailed study to evaluate several possible solutions and the synergies that can result from their implementation.
Then operating costs; we select components for their high efficiency (to ensure production at a lower cost), durability (to ensure long-term operation) and low carbon footprint (for a reduced environmental cost).
This approach based on cost control allows us to offer you a very short return on investment (less than 5 years) for a very long installation life (at least 50 years).
Up to 100% coverage of thermal needs (heating, cooling, DHW).
To ensure your thermal comfort at all times, we install in our systems many intelligent sensors (using communication technologies) in order to be able to react to the slightest change in temperature.
Every second, the operation of the system is evaluated and compared with the set point parameters and external parameters (temperature, sunshine, etc.).
The control and regulation units that equip our facilities use artificial intelligence (AI) technologies to modulate the operation of the system by integrating in real time various parameters such as temperature histories, weather forecasts and pre-established scenarios of site use.
In the case of a renovation project, the WATeBOX management system can integrate existing equipment (heat scattering units, solar panels or photovoltaics) into the operation of the complex.
100% renewable energy, no CO₂ or GHG emissions.
It makes no sense to propose a heat management concept without integrating environmental preservation values.
For WATINYOO, not only does energy make sense if it is renewable, but heat production must be eco-responsible by limiting the impact on the environment.
The solutions we propose are based on a circular analysis of the need to limit unnecessary production. For example, a heating requirement and a domestic hot water (DHW) requirement are often treated separately when they could be shared…
In this example, we would propose a heat pump (HP) to cover the need for heating and DHW at the same time. In addition, by combining hybrid solar panels (heat recovery photovoltaics) with it, we cover a large part of the HP’s primary energy needs (electrical) while providing the bulk of the thermal energy needs for the production of DHW. This is energy that is not wasted and heat that is not produced unnecessarily.
Through this approach, we contribute to the reduction of GHG (Greenhouse Gases) and of CO₂ emissions on our equipment. It’s good for the planet.
The heat pumps (HP) are connected to the water loops installed in the ground, thus benefiting from an ideal inlet temperature for a maximum COP.
By associating the water loops with each other, by means of plate heat exchangers, we create a micro intelligent heat network (SmartGrid thermal) able to ensure the transfer of the calories required by the different WATeBOXconnected.
Thanks to the WATeBOX(control and regulation unit), each installation can automatically communicate with the other installations in the network in order to transmit heat requests or respond to requests initiated by other WATeBOXwithin the same network.
The extension of the network makes it possible to increase the number of additional renewable energy collection points (roof, grey water, etc.) and, consequently, to contribute to improving their performance.
TECHNOLOGIES
WATINYOO
proposes a circular approach to heat management, based mainly on the use of naturally available renewable energy sources. The capture and management of these heat streams uses proven technologies, recognized for their robustness. By associating several technologies with each other, we create a synergy whose result is an unprecedented energy efficiency …
THE WATeBOX
As the heart of the installation, the WATeBOXis responsible for controlling and regulating energy flows.
It manages the automatic regulation of the elements (sensors, pumps, probes, etc.) that ensure the operation of the system.
It exchanges with the network its operating data and heat requests (transmitting or receiving).
Finally, it ensures the recording of contributions to the network, thus enabling each subscriber to benefit from a remuneration corresponding to his contributions.
The plate heat exchanger
Plate heat exchangers are used to connect water loops together to create heating networks.
The metal plates allow heat exchange without hydraulic connection between two loops.
With high thermal efficiency (95 % heat transfer), the exchangers allow heat to be transferred from one loop to another almost without loss.
Hybrid photovoltaic panels
Hybrid photovoltaic (PV/T) panels are designed to produce electrical energy from solar radiation (photovoltaic) and convection heat from solar thermal energy.
The installed PV/T surface area (optionally combined with batteries) covers all or part of the electrical energy needs of the installation (heat pump + accessories) while providing additional heat that can be used for the production of DHW.
The water loops
We use a temperate water loop (maintained at around 15°C) to supply the heat pumps (HP) connected to it.
Made of a Ø 225 mm high-density polyethylene (HDPE) pipe for a length of several hundred meters, the water loop allows a large quantity of liquid to be stored.
The water contained in the loop will draw the natural heat from the ground (geothermal principle) at a depth of 1.50 m.
Unlike aerothermal heat pumps (which draw heat from the ambient outside air), water-loop heat pumps benefit from an optimum temperature all year round for much higher efficiency.
Geothermal heat pumps
The efficiency of a water heat pump is much higher than that of an air heat pump (using the heat from the outside air).
The coefficient of performance (COP) of an air heat pump is 4.5 (or 4.5 thermal kWh produced for every 1 electrical kWh consumed) when that of a water heat pump (with water at 15 °C) reaches 7.3 (or 7.3 thermal kWh produced for every 1 electrical kWh consumed).
Geothermal baskets
The geothermal baskets consist of a polyethylene pipe (Ø 25 mm) arranged in a spiral over a height of 2 to 3 m.
Installed in the ground (-4.50 m), they contribute to the regulation of the geothermal water loop by capturing heat from the ground (or dissipating excessive heat from the loop).
Each basket (diameter of 1.20 m) represents an Exchange length of the order of 100 m for a thermal power of 700 to 1200 W depending on the nature of the terrain.
