Oil-fired condensing boilers bring high efficiency to listed building

Two oil-fired condensing boilers have been installed in a Grade 2 listed building in Yorkshire to provide space heating and domestic hot water. Supplied by Atlantic Boilers, they use outside air for combustion and achieve an annual efficiency of at least 92% and up to 99%. which is said to be 40% better than conventional modern boilers and up to 20% better than conventional condensing boilers. Flue-gas temperatures are always below 50°C, so low-cost plastic flues can be used.

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.

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.

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.

Underfloor heating in zero-carbon building

Underfloor heating has been chosen for a ground-breaking zero-carbon house project in the Shetland Islands. The project aims to show how an holistic approach to renewable energy can eliminate household carbon emissions. The Osma underfloor heating system is supplied with hot water by an air-to-water heat pump, which also provides domestic hot water via a heat store.

Electric underfloor heating is simple and cost effective

Electric underfloor heating mats from Creda are only 3 mm thick and can be used with any type of flooring — including ceramic tiles, carpet, laminate or wooden floors. They can used for new build or refurbishment projects in homes. Benefits include low capital cost and easy installation. They gently emit heat to provide an even, draught-free and warm environment. Temperatures are regulated by a wall-mounted multi-controlling thermostat that allows for 7-day programming.

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?
