RenoXtra – savings of up to 40 per cent The RenoXtra high efficiency combination condensing boiler from Johnson & Starley features a gas saver module built into the cabinet of the boiler and provides additional system efficiency. The module works by recycling flue gas heat, extracting virtually all the energy to heat the incoming cold water. Reclaimed energy is stored in the unit and is used to pre-heat the incoming cold water. This results in extra domestic hot water (DHW) efficiency, lower gas consump- tion, lower running costs and reduced carbon emissions. It can also help to reduce DHW delivery response time. RenoXtra has a one-piece stylish appearance and to ease installation by reducing the lift weight; it is delivered in modular form. The complete assembly is mounted on a wall jig that contains the necessary fittings to connect the gas saver to the main body of the boiler.
enq. 209 Testo 480: professional high-end solution for climate measurement
Whether it is for testing ventilation and air-conditioning systems, evaluating the comfort level at workplaces or for testing in calibration labs, research labs and facilities: the Testo 480 is the new high-end device for the required high accuracy meas- urement. With an intelligent calibration and sensor concept, flexible data management and professional report generation via PC software, as well as numerous additional functions, the highest of requirements for extensive and advanced climate measurement are fulfilled in every regard. System-related measurement uncertainty is a thing of the past. Cutting-edge measurement technology means quick, easy and extremely professional measurements. Testo fulfils these requirements consistently with its new 480 and its probes so as to save customers time and money, while also guaranteeing them maximum measuring reliability and flexibility. The result reflects the simple calibration concept and intelligent probes that set a new standard in measuring technology. The climate measuring instrument is a high-end solution when it comes to measurement data management and report generation too. Users can transfer measurement data to the PC easily and flexibly via USB cable or SD card and manage this data efficiently using the PC software. The central trackpad ensures con- venient navigation through menus and settings. Air conditioning engineers also have guided measurement programs, such as for standards-compliant grid measurement on a HVAC system in accordance with EN 12599. All relevant climate param-
eters can be monitored using the extensive probe range including flow, temperature, humidity or CO2. This not only optimises the comfortable atmosphere in offices and living spaces, but can, for example, also prevent mould growth.

Vectaire ventilation units’ SFP rating improved Vectaire Ltd has improved the SFP rating on the WHHR100/90DC-B Plus and the MBOX125/2DC-B. They have been retested by BRE and the results pub- lished. The WHHR100/90DC-B Plus is a whole house ventilation unit with heat recovery, for installation in homes and offices. Its DC motor gives high efficiency, low energy usage and recovers 92 per cent of heat from extracted, polluted air. It is for loft, roof void, or cupboard installation. The MBOX125/2DC-B is an effi- cient, low energy solution to condensation and pollu-
tion, providing low level continuous ventilation. It is for loft or roof void installation and requires only one discharge grille. Also available with rectangular spigot - MBOX125/2DC204-B. Both units are continuous running with choice of trickle and boost speeds with low noise levels and running costs. They are compliant with Parts L and F of the Building Regulations.
