Loops of small diameter polyethylene-coated copper tube are buried between 50cm and 60cm below the surface of the garden of the house to form a captor through which refrigerant fluid is pumped, typically R407c blend. A scroll compressor and a stainless steel plate heat exchanger within the generator unit complete the circuit to transfer the energy captured from the soil into the house.
The energy taken from the soil is quickly and continually replaced by sunlight, wind and rainfall, but at the same time the captor is protected from sudden ambient temperature changes. The use of this free energy enables a COP (coefficient of performance) of between 3.9 and 5.1, which means that for every kW of electrical energy consumed to operate the generator, the system produces between 3.9 and 5.1 kW of energy to heat the building.
In order to save precious and expensive space within the house itself, the generator unit is designed to be very compact, and most importantly, to be installed outdoors. Here, it can be mounted close to an outside wall, or lost in amongst the plants and bushes, which incidentally are unaffected by what is going on beneath them. Only a small control panel, together with the water pump and connection components are installed inside the house, offering very practical space benefits in garages or utility rooms, the normal hiding place of traditional heat-pump based heating systems.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
