Best-value optioneering

15 November, 2005
When capital cost exceeds the available budget it is time to practise best-value optioneering — namely, investing in the right solution, not in just doing the project really well. ANDY GREEN explains.
Underfloor heating
COLIN PAVEY highlights the benefits that are making underfloor heating the system of choice for commercial and public-sector buildings.
sports hall
Radiant tube heating is among the most economical forms of space heating on the market. It is clean, energy-lean and responsive. HOWARD MARFLEET looks at the options and applications for radiant heating.
Seward
With financial support available for both commercial and domestic projects, TERRY SEWARD examines the technology of heat pumps for space heating.
boiler
DAVID WHITFIELD explains how the built-in modulation and control capabilities of modern condensing boilers should be utilised to achieve more efficient underfloor heating systems.
LST
A low-surface-temperature (LST) fan convector has been developed by Biddle Air Systems in response to customer demands for a fan convector with a surface temperature no greater than 43°C.

Radiator-cleaning service

14 November, 2005
Coverad, which makes and fits LST radiator and pipe covers, has expanded its service for cleaning radiators and covers to all existing and new customers, regardless of the make of cover or radiator type. The cleaning system was developed with estates and infection-control departments in top UK hospitals.
mosque
A bank of four Broag Quinta wall-hung condensing boilers serve the space-heating system for a new mosque in Bradford. They were supplied complete with cascade kit for the 30 m-square Madni Jamia Masjid, which has been built and furnished in stages over the last three years as the money was raised.
hotel
Following serious damage to the Wellington Hotel in Boscastle, Cornwall, by flash floods in August 2004, the heating and hot-water requirements are served by a Hamworthy Milborne 502 wall-hung modular condensing boiler with an output of 100 kW.
carpets
Tests carried out for Nu-Heat by BSRIA on the effect of carpet on the performance of underfloor heating have shown that much heavier carpets can be used than is generally recommended.
