The role of manufacturers

21 October, 2006
Manufacturers have a major part to play in responding to climate change says GERRY STAPLEY.
Northleigh House
Conventional air conditioning may not be the best way of delivering comfort in buildings as ambient temperatures rise.JOHN STAUNTON discusses an alternative.
roof
RICHARD SCOTT explains why sustainable energy is no longer an option but a necessity — and looks at heating and hot-water innovations for the 21st century.
heat pump
A small village in North Yorkshire is a working model of the effective application of renewable-energy technologies.
church
Effective and energy-efficient heating for a village church in Gloucestershire is provided by an air-conditioning system — used purely for heating. Such is the efficiency of Toshiba’s Super Digital Inverter Split heat-pump system with a COP of over 4.0 at full capacity that it provided an effective replacement for electric radiant heaters in this Methodist church, which has no gas available. The system was suggested by local air-conditioning contractor Eesicool.
HVCA
British business wasted nearly £600 million through poor energy management this summer. If nothing else gets efficiency changes made, then greed will, says HVCA president MIKE McCLOSKEY
PV
To speed up the installation of photo-voltaic systems by up to 90%, Wieland Electric has developed a specialised connection system.
heat pump
The Thermia Diplomat heat pump is now available from Eco Heat Pumps and can extract heat from a variety of sources — ground loops, lakes and outdoor air.
Xcell
A whole-house heat-recovery system from Xpelair is said to be up to 92% efficient. The Xcell 150 unit is designed for smaller dwellings and is the smallest in the Xcell range. It can be installed in existing buildings.
clyde
Clyde Energy Systems has helped bring Bromley Council up to speed on condensing boilers with a CPD session on Part L of the Building Regulations and the replacement of old boilers with condensing boilers.
Vaillant
Vaillant claims that its AuroTherm VFK 900 flat-plate solar collector is the highest performing available in the UK It joins the company’s total-solar-system solution launched earlier this year.

Boiler burns rape-seed oil

17 October, 2006
Rape-seed oil can now be used as the fuel for the R Series of condensing boilers from Atlantic Boilers. The rape-seed is stored like conventional fuel oil in an external or bunded vessel and piped to a pre-heat tank within the boiler, from where it passes to the burner. The rape-seed oil burns with the same maximum condensing efficiency as light oil and natural gas.
Kildare
Occupants of a dramatic office building that has won a RIBA award can control the temperature of their surrounding office environment from their PCs — thanks to an innovative natural-ventilation system from SE Controls.
training
Over a hundred heating engineers have qualified for the BPEC certificate in solar domestic hot water by participating in Vaillant’s training programme. This certificate gives candidates automatic entry to the Government’s Clear Skies Scheme, which is now part of the Low Carbon Building Programme managed by Energy Savings Trust. The scheme gives householders access to grant funding for fitting solar heating.
Stiebel
Stiebel Eltron offers a range of solar systems for generating domestic hot water. They are available exclusively through Applied Energy, with a nationwide after-sales services and approved-installer network.
factory

The power of solar energy

17 October, 2006
Tucked away in the north-east corner of Wales is a factory producing photo-voltaic solar panels and being installed in a rapidly growing number of substantial projects in the UK.
graph
When a fixed-speed pump is preferred over a variable-speed unit, there is no need to compromise energy efficiency, as ROY HENDERSON explains.
Barrett
Pump specialist Smedegaard UK is developing a new corporate image following the recent appoint of Chris Barrett as general manager. Smedegaard is a Danish company and makes pumps in Denmark and Switzerland. The UK operation at Bridgewater makes pressure and boosting equipment covering commercial/domestic, industrial and fire-fighting applications.
Britta Frank
Their ability to save energy is just one benefit of applying variable-speed drives to pumps. BRITTA FRANK explores other possibilities.Variable-speed drive (VSD) has become a familiar term, and many have embraced this technology to reduce energy consumption and keep costs down. VSDs have been extensively tried and tested with pumps and pumpsets for a number of years, but further technological improvements continue to provide benefits for the end user.
booster
AquaTech has extended its range of VariMatic water-pressure booster sets, based on combination of Smart Logic controller and variable-speed inverter technology.
taconova
To simplify the installation of solar heating systems, Taconova has introduced a solar station combining pump, regulator and air vent. Designed for commercial, public-sector and domestic applications, the FV 70 Tacosol 3.0 enables hydraulic balancing, flow measurement and venting to be performed at the same point.
sledgehammer
By exploiting the latest in pump technology, Grundfos is moving to reduce the energy consumption of domestic circulators by up to 80% compared with today’s average.
pump room
PETER NEARS explains why variable-speed pumps should be commissioned by a competent person to achieve effective operational performance, maximise energy savings and prolong life expectancy.
