Dyffryn Mymbyr puts its trust in biomass
A
fter numerous successful installations of biomass systems in properties owned by the National
Trust, Windhager UK has been specified to provide an energy efficient heating system at Dyffryn Mymbyr in Snowdonia following the restoration of the estate’s 19th century farmhouse and cottage.
The BioWIN 52kW cascade system installed at the estate by Ian Ryan of Mon Heating in conjunction with Windhager UK consists of two separate 26kW boilers operating together in cascade to deal with the fluctuating heating requirements for the properties as efficiently as possible. Maintenance work can be carried out easily without having to shut down the full heating system. The cascade system installed boasts an impressive output range between 7.5kW up to 52kW. The boilers are served by wood pellets transported by lorry from Ruthin and blown into the 9.6 tonne bulk capacity hopper. The pellets are then sucked from the large storage hopper into the individual boiler hoppers and then fed when required into the burner bowl. The system and associated plant are located in the former garage adjacent to the rear of the cottage. The wood pellet system has
only 1/13th of the carbon emissions of a standard oil heating system and all wood pellets used for the system meet FSC/UKAS sustainability credentials and a large hopper has been installed to minimise the transportation of fuel. Although the National Trust has over 60 biomass systems on its estates, the Windhager two boiler cascade district heating system is the first of its type for the Trust. Windhager systems have also been installed in several farmhouses and offices owned by the National Trust nationwide in projects such as the installation of a 50kw Windhager LogWIN boiler to heat the tearoom, chalet pavilion and educational facilities on site at Cardingmill Valley, saving nearly £4,500 in operational costs per year. Impressed with the results and cost savings, project managers at the site have now also specified a VestoWIN central heating cooker from Windhager, a reliable and environmentally friendly traditional cooker with all the advantages of a wood burning central heating system.

New steel fixings solutions
impson Strong-Tie has launched a new range of stainless steel fixings – a unique collection of cladding installation solutions featuring premium quality screws and nails, to join its extensive list of products.
S Suitable for use with all types of
decking, cladding (timber and fiber cement) and even barn construction and marine installations, the screws feature unique point designs and thread profiles to make driving easier, whilst the nail heads have been designed to refract light to ensure that they blend with wood materials.
The range is supported by new
packaging and a brochure which also features the new Angle Bracket Connector (ABC), enabling vertical battens to be fixed directly to the supporting structure. Chris Sanders, Marketing Manager at Simpson Strong Tie said “This latest addition to the Simpson family of construction products is aimed at applications where durability, corrosion resistance and aesthetics are all equally important. “High-end decking installations are an area where stainless screws are favored, as beautiful hardwood decking can develop unsightly stains from traditional fixings. Furthermore, as building designers look for ever more sustainable methods, many are turning to timber and fiber cement cladding, an application where stainless steel nails are an ideal solution.” For further information visit

characteristics of a forced vortex, the new ACO Q-Brake Vortex stormwater discharge flow controller allows up to a 10% cost saving in upstream surface water storage infrastructure. Developed by ACO Water Management, the efficient mechanism, which has no moving parts, allows an outlet cross section 4-6 times larger than traditional flow controllers, making it less prone to blockage, easier to maintain and, by permitting higher flows at lower head pressures, significantly reduces stormwater storage volume requirements. To ensure that specified discharge rates to any downstream watercourse or sewer are accurately controlled, each ACO Q-Brake Vortex is individually sized and manufactured to the requirements of a specific project. This is done quickly through ACO Water Management’s Design Services Team. When complete, each finished ACO Q-Brake Vortex is supplied with a head discharge table and graph plus full installation details. Manufactured from grade 304 stainless steel, the ACO Q-Brake Vortex is fitted with a patented bypass door and emergency drain down facility. Operated by pull cable fixed to the bypass door, it allows the ACO Q-Brake unit to be remotely accessed from the surface, minimising any need to enter the manhole chamber (a key requirement of Building Regulations 2000 Section H) and enabling the upstream system to be independently drained, completely bypassing the ACO Q-Brake’s inlet. ACO Q-Brake Vortex flow control has a selection of fixing options that can be used to secure the unit to flat sided or round manhole chambers. Every unit is UK manufactured and has been independently laboratory tested to verified discharge rates.
