Saint-Gobain PAM UK has been awarded a major contract to supply more than 70km of its EN545 approved Natural ductile iron pipe range for a flagship project for Wessex Water.

The water company is constructing a number of schemes as part of its water supply grid project to help meet future demand without developing new sources. The project will allow Wessex Water to improve the security of supply for customers – even in the event of a catastrophic failure – and meet reductions in abstraction licences required by the Environment Agency to improve flows in some rivers and protect their ecology. It will also help deal with seasonal or occasional deteriorating raw water quality – particularly increasing concentrations of nitrates at some groundwater sources – as well as meeting future water supply demands. It includes the construction of a new water main to transfer water from the south of Wessex Water’s region, in Dorset, to Salisbury in Wiltshire via Blandford and Shaftesbury.

Due for completion by 2018, much of the pipeline route passes through the Cranborne Chase and West Wiltshire Area of Outstanding Natural Beauty and has been designed to avoid environmentally sensitive areas.

The first order will see around 17km of DN350 pipe supplied for a twin main section between Sturminster Marshall and Snowsdown.

Wessex Water held a number of initial consultations with Saint-Gobain PAM UK to discuss the options for pipe materials. Ductile iron was ultimately selected by Wessex Water for the majority of the project for its strength. The design was able to achieve a bed and haunch to support the pipe, which has reduced the import and export of materials, lowering the impact on the environment. Ductile iron pipes also offer installation flexibility, with multiple pipes in a single trench, as well as a relatively short and discreet installation period, meaning trenches do not need to be left open for extended periods. With the native soils being primarily chalk, the ability to rapidly backfill trenches quickly is key, as chalk left at a trench side for long periods could be exposed to the effects of heavy rainfall, making it more difficult to reinstate.

The Natural range, available in diameters from DN350DN to DN600DN, offers strong corrosion resistance in soils with resistivity as low as 500ohm cm through its 400grm Zinc Aluminium alloy protection. The protective coating also eliminates the need to identify transition points between medium and low resistivity soils, where alternative systems may require a change from standard to supplementary protection.

Simon Cottingham, Director of Key Accounts and Major Projects at Saint-Gobain PAM UK, commented: “We worked closely with the Wessex Water team to define the scope of the project and recommend a solution which would allow the customer to benefit fully from the performance attributes offered by ductile iron pipes. We are very proud of taking part in this project and contributing to its success.”

Davin Eversett, Project Manager at Wessex Water commented: “Wessex Water’s project management team in conjunction with the internal design and procurement teams have worked with Saint-Gobain PAM UK in the development of this pipeline and concluded that ductile iron pipes will offer the lowest whole life cost as well as the flexibility to deliver what will be a challenging construction programme.”

The U3000 & U1000 latest generation of clamp-on, ultrasonic flow meters from Micronics are a viable alternative to in-line meters for HVAC metering, in both retrofit and new build applications, delivering major installation savings, minimal downtime, maximised availability and significant maintenance benefits.

Liquid flow metering including LTHW, Chilled water and DHWS plus flow measurement for Thermal Energy measurement are all areas where clamp-on meters offer a best value solution for Building Services or Energy Management i.e. they will be significantly cheaper to install than traditional in-line meters and as they’re non-invasive they deliver maximum availability through dry servicing and minimal maintenance.

The larger the pipe size the greater the installed saving will be but with the elimination of flanges and by-pass valves significant savings are available for a wide range of pipe sizes with major savings for larger applications! The following is a comparison of new build installation costs the comparable savings for retrofit would be higher:

The above demonstrates the potential installation price savings from using a clamp-on solution, which would deliver an installed clamp-on meter price with savings ranging from significant to major from 50mm upwards. And with the added benefits of being non-invasive, requiring only dry servicing and maximising availability. Call+44 (0) 1628 810456 or visit www.micronicsflowmeters.com for further info.

As the requirement for cleaner heating solutions gathers pace, condensing biomass boilers – boilers that burn wood pellets made from recycled sawdust or virgin timber from managed sources – are increasingly being seen as sensible options for people looking to reduce their carbon footprint.

One of the leading manufacturers of wood pellet boilers is Grant UK, a company that has been designing and manufacturing reliable, high quality, easy to install heating products for more than 35 years. Perhaps best known for their award winning oil fired condensing boilers, Grant UK has expanded its business very successfully into the new world of renewable heating technologies, offering the most efficient air source heat pumps, a sector leading eco efficient solar thermal system as well as the Spira Wood Pellet boilers – all in a range of sizes that would complement virtually any UK residence.

Grant has welcomed The Department of Energy and Climate Change (DECC) decision to include the Grant Spira range of Condensing Wood Pellet Boilers in the Domestic Renewable Heat Incentive Scheme (RHI). The MCS approved Grant Spira Condensing Wood Pellet boilers are available in outputs of 6kW up to 72kW and deliver efficiencies up to 97.4% which is impressive by any standard. Models are available for domestic properties or small scale commercial installations, the latter achieved by using two boilers mounted side by side. The solution is very efficient as the precise electronic burner control allows both units to modulate as one, down to just 25% of maximum load when the full output is not required.

With most pellet burning boilers, up to 20% of the energy that is produced is lost to atmosphere via the flue system. The Spira range features a unique secondary condensing heat exchanger designed to capture some of this lost latent heat energy, conveying additional warmth for the home. It’s just one example of the intelligent, value added design features you can expect from Grant UK products.

The Grant Spira Wood Pellet boiler requires very little maintenance in comparison with other wood pellet appliances. It has a self-cleaning system for the primary and secondary heat exchangers ensuring the system is debris free. The self-cleaning burner uses a premium EN Plus A1 standard pellet with low ash content, requiring minimal maintenance.

Wood pellet boilers are generally larger than traditional oil or gas boilers and will require a hopper to store the fuel, sited adjacent to the boiler. The Grant Spira is designed to be located in a garage, store or outhouse building, so it’s important to consider its position prior to installation. In addition, ventilation is a crucial factor for the appliance and the flue in order that its operation is safe and efficient. The boiler has an automated cleaning cycle which does result temporarily in an increase in noise levels, so that too should be considered when selecting a location for the boiler.

The Pellet storage is available in capacities from 3 to 6 tonnes. Pellets can be auger fed from storage hoppers into the intermediate pellet store supplied as standard with the boiler. Alternatively, for installations where an auger fed hopper is unsuitable, there is the Grant SpiraVac unit which swiftly and conveniently moves the pellets from the Grant external store to the internal Spira boiler hopper via vacuum hose. The system enables the bulk pellet store to be positioned up to a distance of 20 metres from the boiler.

Managing Director of Grant UK, Paul Wakefield says: “Our training team are seeing a huge increase in demand for knowledge in this arena and courses are at capacity.” Full details of the Grant UK Spira Wood Pellet boiler range and accessories can be found at www.grantuk.com.

Wavin – a leading supplier of water management, plumbing and drainage systems for the building, construction and utilities markets – has upgraded all insulation products in its Thermoboard Underfloor Heating (UFH) range so that it is now easier for builders and developers to score highly when following the Code for Sustainable Homes (CSH).

The upgrades affect Thermoboard Low-Build, Pocketed Polystyrene and Foiled Polystyrene heating panels, improving both their strength and environmental characteristics.

The change in the extruded polystyrene insulation employed means that Long Term Strength is now 300% of what it was and that its Global Warming Potential (GWP) has been reduced to less than 5. Compressive Strength has risen from 200kPa to 300kPa while the figures for Long Term Strength, over 50 Years with 2% compression, have risen from 40kPa to 130kPa.

The reduction in GWP benefits all properties being assessed against CSH, where credits are awarded when all insulants used within a property have a GWP of less than 5. Now builders and developers following the Code can attain higher scores with minimal effort.

The Thermoboard range of products provides the ideal answer to surface heating and cooling within any domestic or light commercial environment, being designed and tested to the highest industry standards.

Iron technology leader Saint-Gobain PAM UK, part of leading international materials company, Saint-Gobain, has further demonstrated its environmental commitment through several major investments at Holwell, near Melton Mowbray, including one which has seen CO2 emissions from its cupola furnace – the biggest of its kind in the UK – fall dramatically.

The previous installation of a dry bag filter system has meant particulate emissions have been reduced by 99 per cent from the cupola furnace. As a result, emissions are now less than 0.3kg per tonne of castings, while the company has reduced site water use by 63 per cent and electricity by 9 per cent, and completely eliminated the use of caustic soda previously employed for cleaning the wet filtration system. The move also brings a reduced risk to permitted drainage discharge points.

A second substantial investment has been the installation of a heat exchanger to recover waste heat from combustion gases. The energy regained by the heat exchanger will be used to re-heat input air to the furnace, resulting in an annual saving of 2,200 tonnes of CO2. A new control system has also been established at Holwell, which will facilitate both the cupola furnace’s filter system and the new heat exchanger.

Paul Minchin, Managing Director of Saint-Gobain PAM UK, added: “It is important to us that we continue to invest in measures that will put environmental savings at the forefront of business. The investment in the cupola furnace’s new filtration and heat recovery system has reduced CO2 emissions enormously, and is just one example of our business ethos, which has minimising our environmental impact at its heart. These measures will pave the way for further developments in optimising energy use, reducing gas consumption, use of low level waste heat and the recycling of collected particulates.

“The investment also shows our commitment to maintaining a UK manufacturing base, with our site near Melton Mowbray providing a truly local service to UK customers, removing the supply chain delays which can occur with imported products.”

British Gas (the UK’s leading supplier of services to energy customers) has recently started using Hep2O plastic systems alongside, or instead of Copper for installations. This now means that British Gas’s network of around 10,000+ engineers and the many thousands of heating projects they install and maintain each year, will be able to benefit from Hep2O’s multiple advantages in both installation and use.

For installers, the product is quick, simple and safe to use and is backed by an industry-leading 50-year guarantee, a UK-wide distribution network and comprehensive technical support. The customer benefits from a product that will never be compromised by either scale or corrosion and is quieter in use than more traditional equivalents.

Gareth Samuel, Wavin Product Manager Comments “British Gas went through a rigorous process in selecting a plastic system, and by adding Hep2O to their approved products they are giving installers the choice to select the most appropriate product for the installation.”

Gareth adds “We are delighted to be involved with British Gas and will be working with their training academies to show installers how to maximise the benefits of the system, and save valuable time on their installations”

Another major innovation incorporated into this product is In4Sure™ joint recognition and HepKey™ secure demounting.

Developed to give installers a fool-proof means to test that a joint is secure, the In4Sure™ ‘joint recognition’ technology allows the user to simply push in the pipe and twist so they can ‘feel the rumble’. The profiled end of the re-designed SmartSleeve™ interacts with castellations inside the Hep2O fitting to know that they have made a fully secure connection.

The HepKey™ demounting system allows the system to be adjustable but secure, so that pipes can be released easily and quickly as the HepKey Plus™ releases the grab-ring within the fitting allowing removal of the pipe from the otherwise tamperproof joint; while the smaller pocket size HepKey™ provides a handy pocket-size alternative. Hep2O pipes and fittings are available in four diameters: 10, 15, 22 and 28mm.

Daikin Europe N.V. has added to its green energy bank by the installation of almost 2,000 solar panels at its Ostend, Belgium production plant. Designed to produce around 400,000 kW electricity per year (the equivalent consumption of 115 households), the system went on stream at the end of August and the energy generated will help power Daikin’s on-site operations.

Daikin Europe originally considered the use of solar panels some five years ago but since the efficiency of the then available technology was inadequate, purchased green electricity on the market, reducing its environmental footprint and resulting in a drastic reduction of CO2 emissions. However, solar panel efficiency has improved considerably and the decision to install panels was examined again and approved in 2010. Work began at the end of April and the system became operational at the end of August.

The deployment of solar panels is very much in line with the overall environmental policy of the company and its intention to decrease dependence on electricity suppliers and the choice of solar panels was taken after considering other solutions including wind turbines. The installation will result in a yearly savings of up to 160 tonnes of CO2. System capacity of 400,000 kW per year was dictated by limitations in the region’s electricity grid due to the high number of renewable systems already in place.

The solar panels are located on certain plant roofs at Ostend site and to highlight the effort and increase environmental awareness the performance of the installation will be visible via screens in the factory and reception area. Real time data will include daily energy production, CO2 saved and comparisons with previous periods. Minimum life of the installation is 20 years but actual life is expected to be 30-40 years.

Daikin Europe N.V. announces the expansion of its Daikin Altherma heat pump range to cover large-scale commercial applications in which space heating and hot water production are a priority. Due to the use of Daikin Altherma cascade technology, large volumes of hot water (with temperatures up to 80°C) can be produced efficiently, making the system ideal for applications with a high demand for space heating and/or hot water heating.

Large capacity hot water production for the commercial market

The optimised Daikin Altherma Flex Type series produces leaving water temperatures from 25° to 80°C, making it suitable for all types of radiators, under floor heating, fan coil units, heat pump convectors as well as hot water production. Typical applications include hotels, fitness centres, spa facilities, hospitals, libraries and schools. The high leaving water temperatures also make it ideal for upgrading existing heating systems, allowing retention of existing high temperature radiators.

The use of Daikin Altherma cascade technology: two refrigerants – R-410A and R-134a – in a cascade configuration, enables the system’s high leaving water temperatures to be produced without an electric heater. The outdoor unit elevates the temperature and pressure level of the first refrigerant cycle (R-410A) and the indoor units raise this to even higher levels with the second refrigerant cycle (R-134a), resulting in water temperatures up to 80°C using only heat pump technology.

Hot water temperatures up to 75°C result in highly efficient hot water production with rapid heat-up times and the system can be connected to Daikin hot water tanks as well as to (existing) 3rd party tanks. Daikin solar heating can also be integrated for even greater efficiency.

Low running costs
Daikin Altherma cascade technology, in combination with inverter controlled compressors and weather dependant temperature control, results in extremely efficient operation. Running costs can be up to 36% less than comparable oil or gas installations, with up to 35% less primary energy use and up to 71% less CO2 emissions.

Furthermore, optimal dimensioning further enhances efficiency, the system’s modular construction and several different capacity classes of indoor and outdoor units allowing precise configuration for specific needs. The indoor and outdoor units are compact and lightweight, for quick, flexible installation.

The Daikin Altherma Flex Type units extend the existing Daikin Altherma range of low temperature and high temperature systems intended for individual houses and apartment blocks.

Daikin Europe products are distributed in the UK by Daikin Airconditioning UK Ltd and Space Airconditioning plc.
