Water source heat pump systems are becoming increasingly popular, but one lesser known water source application is open loop systems. 

Open loop collectors take the form of two separate straight pipe collectors. These designs abstract and filter the water through the heat pump. This water is then discharged either back to the water source or another discharge area.

Renewable heating expert Finn Geotherm, has completed a landmark installation for leading European agricultural plant breeder RAGT Seeds in Cambridgeshire, to deliver both heat and passive cooling with significant energy savings.

RAGT's initial brief was to reduce the heating costs for its six glasshouses, which are used for developing new crops. LPG had previously been used to heat the glasshouses which, with a U value of around six, meant the boiler was in constant use in winter, leading to issues with fuel supply and heat distribution as the system couldn't keep up with the heat being generated. RAGT needed a new system to work with its existing grow tubes.

CP Electronics, the industry-leading designer and manufacturer of energy-saving lighting controls, has unveilled its next generation of Vitesse Plus, a seven-channel lighting control system specially designed for educational and commercial applications, as well as retail spaces.

New from Bright Spark Solar is the Solar Sensor LED Light.

This inexpensive solar-powered LED floodlight is robust and fully weatherproof and provides some powerful lighting using free solar energy for a host of applications from driveways and yards to remote buildings, paths and entrances.
