Heating, ventilating, and air conditioning

An energy trio... Energy autonomy thanks to combined geothermal, biomass and solar power Up to 80 % of heating by biomass-fired combined heat and power plant, ~20 % covered by geothermal Fronius International, based in Pettenbach, Upper Austria, is active in the fields of welding technology...

Heating costs through the roof? Consider cladding and insulation Cladding is used to provide an additional layer of insulation to a building which improves thermal performance and weather resistance. It can be made using a variety of technologies, materials and procedures. Metal, wood, brick, vinyl...

Have you looked into those cavities? Cavity wall insulation Insulating wall cavities can help you cut energy use and save money by reducing heat lost through walls in colder months, and keeping it out during warmer months, which cuts back on cooling needs. Cavity wall insulation can be used in any...

Free cooling can assist in cooling water which is subsequently used in industrial processes or air-conditioning systems. It is an economical system which can help reduce costs and energy uses. Free cooling uses low outside temperatures to chill the water and can replace mechanical refrigeration...

The solar thermal identity… or should that be supremacy? Solar thermal (also called solar heating collector) is a mature renewable energy technology. Solar collectors have recently been used not only for the preparation of hot water and pool water, but also for heating objects and devices. It can...

Air source heat pumps… an absorbing proposition Air source heat pumps absorb heat from the outside air. This heat can subsequently be used to warm radiators, air convectors and water, or in other heating systems. The process lowers fuel bills, cuts carbon emissions, and requires minimal maintenance...

A great introduction to ground and water source heat pumps Ground and water source heat pumps (GSHP) are easy to run once installed and provide low-carbon heating or cooling. Average reduction in CO2 emissions are reported to be from 25 % to 70%. These reductions depend on the use of GSHP - either...

Biomass heating is a proven technology which most commonly uses virgin wood, certain energy crops, industrial wood residues and certain agricultural residues to produce heat. Biomass is considered a low-carbon technology if the feed material is derived from sustainable sources. Significant carbon...

Economisers are gas-to-water heat exchangers located within a purpose-built flue section. They are used to recover heat from flue gasses for shell and water-tube boilers. The main use of economisers is to pre-heat boiler feed water. An economiser can potentially be retro-fitted to most steam and...

Case for dual burners Installation of dual fuel burners to replace heavy oil burners, with the aim of increasing fuel-heat effectiveness and avoiding radiation heat loss, among others. Steam and high-temperature hot water (HTHW) boilers is a category of technologies commonly used in industrial...

According to the Carbon Trust, heating can account for as much as 60 % of total energy use, yet a large proportion of the energy consumed by heating is likely to be wasted due to incorrect control settings. Notably, lowering heating temperatures by just 1º C can save 8 % on fuel consumption, and...
