Air-source heat pumps are more appropriate for replacing central-heating boilers in residential applications than ground-source heat pumps — according to Space Air

Presenting the case for air-source heat pumps

A strong demand for air-source heat pumps designed principally for space/water heating is predicted by Space Air, which distributes Daikin products.

Designing for lower pump energy consumption

While high-efficiency motors and variable-speed drives have a role to play in reducing the energy used by pumps, system design is much more important. Roy Henderson explains.

Not only is modern air conditioning equipment far more efficient than equipment that is 10 years old, but much of it qualifies for Enhanced Capital Allowances.

Taking energy efficiency seriously

Installers, specifiers and manufacturers in the building services industry must do more to educate their end-user customers on the benefits of installing energy efficient and cost effective equipment in their premises, according to Daikin Airconditioning UK Ltd.

The UK’s largest-ever underfloor-heating installation, undertaken by Warmafloor uses some 60 km of pipe. The work was undertaken for Airbus in the wing-equipping area of its aerostructures assembly and manufacturing centre in North Wales.

The role of underfloor heating in a sustainable future

Mike Lamb considers how increasing awareness of the importance of renewable energy adds to the importance of underfloor heating.

The hard facts of good design — Keith Westcott.

Effective underfloor heating depends on good design

Keith Westcott argues that the current boom in demand for underfloor heating makes good engineering based design even more crucial to maximise comfort and efficiency.

Underfloor heating operates very successfully with all types of heat pumps and with the condensing boilers which are now routinely specified.

Boosting the efficiency of underfloor heating with good controls

Graham Richardson explains the importance of controls in enabling underfloor heating to enable the heat generators that deliver hot water to operate at maximum efficiency.

The use of an air-to-water heat pump to serve Osma underfloor heating in this project in the Shetland Islands makes an important contribution to achieving zero carbon emissions

Supporting the future of the building-services industry — Modern Building Services is supporting CIBSE’s Student Bursary Scheme with an award for Adam Beales (centre), an MSc student at London’s South Bank University. He is pictured with editor Ken Sharpe and CIBSE’s Louise Enslin, who looks after the scheme.

Introducing Modern Building Services’ sponsored student

With the building-services industry continually faced with a chronic shortage of graduate engineers, CIBSE launched its Student Bursary Scheme three years ago. It provides a means for companies and organisations in the industry to do their bit for the future of the industry — including Modern Building Services.

Learning to love the Building Regulations

To the ever-growing number of people in the building-services industry who fully appreciate just how much can be achieved with energy-efficient plant and systems in dramatically reducing the energy consumption of buildings and their associated carbon-dioxide emissions, it will come as a culture shock to be reminded that there are plenty of people who do not. In this day and age when all forms of printed and broadcast media are constantly covering the threat of global warming — or at least blaming it for any weather that is perceived to be at all abnormal — can there really be responsible people out there who do not accept that good engineering can readily deliver energy savings of 25 to 30% and more, as highlighted in the link below?

CIBSE low-carbon register progresses towards thermal simulation

A section for those qualified in the use of building-simulation software is being added to CIBSE’s register of low-carbon consultants. It will be launched at the institution’s national conference in London on 24 and 25 April.
