Thermal water system technology could reduce energy bills

In a world that is growing more conscious of energy consumption and sustainability, consumers are looking for solutions that not only make life comfortable but have a low environmental impact too.

Our home heating systems are central to these efforts, with modern heating systems harnessing the power of technology to become more energy-efficient, aiming to decrease carbon emissions while also cutting costs.

Modulating energy consumption to reduce bills

Octopus Energy Heating Limited, part of Octopus Energy Group, has unveiled a cutting-edge innovation in published patent, GB2609902, that leverages technology to optimise and reduce energy consumption. Specifically, the patent is directed to a computer-implemented method for modulating energy consumption in water provision systems.

The patent revolves around the dynamic control of a water provision system in buildings. In essence, it provides a system which is able to accurately predict when peaks in energy consumption are likely to occur – for example, at the end of the working day, and adjust how it heats water accordingly.

When there is a high energy demand in a region, the system switches from using traditional electrical heating elements to a thermal energy storage medium, saving on costs and reducing demand on the power grid. The system takes advantage of off-peak periods when energy is cheaper, to store  thermal energy which can then be used during peak periods, reducing energy costs significantly.

The system’s decision-making process relies on real-time data. Energy tariffs that reflect national or regional energy demands, act as the indicator for implementing energy modulation.

By responding in real-time to energy tariffs, homeowners can enjoy the comfort of a heated home whilst contributing to a significant reduction in peak-time energy consumption.

The method also allows the home to essentially ‘store up’ on heat during off-peak periods, making it a reservoir of warmth when most needed, ensuring efficiency in both energy and cost.

Innovation demonstrates market intent

For Octopus Energy Heating Limited, this patent is not just an innovation but a strategic asset. It places them at the forefront of the energy conservation movement and offers consumers a tangible solution that is both efficient and environmentally conscious.

Patented technologies can provide a competitive edge for businesses. A patent not only offers exclusive rights to the invention but signals to the market a commitment to innovation. Patent ownership can also open the door for licensing opportunities, collaborations and even help to attract investors.
