Cal Bailey shares his hard experience of the benefits of off-site manufacture — especially for pipework.
Microflex preinsulated pipework is available in the UK through Watts Industries. It is composed of thermal insulation around carrier pipe(s) and covered by a double-skinned closed chamber jacket. These pipes can be used for distributing water for heating, cooling and hot and cold water supply services.
The commissioning of piped services inevitably faces time and budget constraints. Peter Rees considers how these challenges can be addressed.
The time taken to power flush central-heating systems can be halved using Adey’s VibraClean radiator agitator.

When in the latter stages of last year, Sir Nicholas Stern in his review ‘The economics of climate change’ highlighted the impact on the world's GDP of climate change, there was considerable scepticism in some quarters. The spread of his predictions was very wide — ranging from unabated climate change costing the world at least 5% of GDP each year right up to over 20% if more dramatic predictions come to pass. At the very best, he believes that the impact of climate change on GDP can be limited to around 1%.
New construction orders for private commercial projects underpinned a 6% rise in the volume of new orders for the year to April 2007 compared with the previous 12 months, according to figures from the Department of Trade & Industry. All figures are seasonally adjusted and at 2000 prices.
Burner manufacturer Riello has called on the Government to produce statutory requirements for the use of biofuel in the heating industry by introducing a heating-fuels obligation.
