smart heating for every home

smart heating for every home

Aalberts hydronic flow control plays a crucial role in shaping eco-friendly buildings and they are now participating in another innovative project where heat in homes is being stored and then used 'on-demand' to provide hot water and central heating.

This venture is also taking place at The Green Village in the Netherlands, where both Aalberts integrated piping systems and Aalberts hydronic flow control previously announced to research and test the use of in-house hydrogen installations in existing buildings.

heat transfer
The heating systems used in many of today's buildings are simply designed to heat rooms to the correct temperature. However, such systems can be far more energy-efficient if heat storage is part of the system. With heat storage you can run the heat source (of all types such as heatpumps, distribution networks, solar panels etc.) at the optimal efficiency rate and make the heat available when needed.

“The project is called the Dreamhûs,” explains Ben Mureau, Director innovation at Aalberts hydronic flow control. “One of the challenges society currently faces is making older houses, such as those constructed in the 1970s, more sustainable and energy efficient. The Dreamhûs project is a scalable, affordable concept that can be used in standard (terraced) houses.

In this project, we are using three flextherm batteries which use phase change materials (PCM) capable of storing and releasing large amounts of energy—one for warm water, one for heating and one for back-up. Imagine the flextherm batteries as innovative 'boilers', which use inorganic salts as PCMs rather than water. The salt is heated to 70C via an electric spiral, and at that temperature it becomes completely liquid.

When someone in the house turns on the hot water tap, for example in the shower, the salt cools down again and gives off the energy to water-filled exchangers, which supply hot tap water. Basically, the flextherm batteries only provide heat when required. We will learn how this system behaves and can be optimised for different real live situations to assure comfort combined with efficiency and off course a fair sales price."

energy for all
With hydrogen technology still under development, Aalberts hydronic flow control are using technology that is both energy efficient and cost-effective. “While we continue to look for hydrogen solutions, we are also working on options for the intervening period,” Ben says.

“And the three systems we are testing are applicable for today and the future.
The first is an all-electric system made for direct heating with electrical elements. The second is linked to a heat network, with the source coming from solar panels, a fuel cell or a heat pump. And the third system is based on a hydrogen-fired boiler or a fuel cell, which is a long-term answer."

sustainable entrepreneurship
Our goal is to add real value within the eco-friendly buildings market, while contributing to Aalberts aim of supporting SDG7, ensuring access to affordable, reliable, sustainable and modern energy. Harnessing cheap and efficient energy is one of society’s great challenges, and we are determined to help advance technologies within this area.
