Condensing boiler manufacturer Buderus has claimed that the newest addition to its commercial range is "a boiler for all occasions". The floor-standing GB312 is, it says, highly efficient and environmentally friendly, and particularly suitable for installation into existing heating systems. The range includes six GB312 models with outputs ranging from 90kW - 280kW, and features an aluminium condensing heat exchanger that maximises efficiency even when heat demand is low, as the boiler can modulate down to 30% of full capacity. The burner is linked to a digital Energy Management System (EMS) which continually monitors the system's heat requirements so that energy is not wasted when demand for heat drops. Intelligent control options and the EMS ensure synchronisation between boiler and heating system and the result is a price/performance ratio that should reduce fuel consumption and return initial investment costs.

As the responsibility of architects and property developers increases to comply with the new requirements specified by the Building Regulations Approved Document B 2006, SE Controls has updated its guide on smoke control systems in residential buildings. ADB's most significant revision is to pinpoint the need for smoke control to be treated as a system, in accordance with European standards. The new document also recognises the now widespread use of smoke shafts. SE Controls managing director Will Perkins says: "Meeting the requirements of Approved Document B is a major challenge for any residential developer. We have updated our Residential Smoke Ventilation brochure to provide all the advice and answers architects and contractors will need."

The partnership between Fernox and Signpost Housing Association has moved into its third year with the implementation of a water analysis service from Fernox. The service ensures that the central heating systems installed in 300 homes in North Dorset retain a valid warranty, as boiler manufacturers are increasingly reluctant to honour warranty repairs where they suspect that the problem has been caused by debris or sludge in the system. Each boiler is pre-commissioned using Fernox Cleaner F3 and Protector F1. On completion, the system water is tested using the Fernox Water Test Kit, and samples analysed to determine its condition, ensuring problems are caught early and repairs because of an invalid warranty are avoided.

An Isle of Lewis Housing Association has chosen Eco Heat Pumps for six new properties in Newvalley near Stornoway. The Eco Thermia Diplomat Heat Pumps are linked to a specially drilled borehole, and provide renewable energy for domestic hot water and space heating for each of the houses. A water-glycol mixture is pumped through pipework in the boreholes, drawing naturally occurring heat into the system from deep below the ground. The heated water - at 12 to 15°C - then enters the flow side of the Eco Heat Pump, where the compressor and condenser brings it to the temperature levels required in the property.

The Ecovector from Smith's Environmental Products is described as the next generation of fan convector, designed for use with the heating systems of today. Designed to look more like a radiator, the flat-fronted convector is operated by a single-speed fan which is claimed to run so quietly, 'it is difficult to tell if the unit is actually turned on.' It also features simple, easy to operate controls and has a built-in thermostat.
