These energy efficient units offer a choice of thermal wheel or horizontal cross flow heat exchangers, are quick and easy to install and have low power consumption. With a flow rate from 0.028 cubic metres per second to 2.22 cubic metres per second, their backward curved centrifugal impellers work hard to ensure fresh and efficient indoor air quality. There are EH versions of both ranges which come complete with wired control panels and LCD screen, which allows for integration into Building Management Systems – free heating and night cooling functions are also provided. Technical and marketing manager, Jennifer Quinn, said: “With much of the conversation for 2016 being around domestic heat recovery, these commercial units ensure that public buildings do not miss out on the energy savings HRUs can offer. They also play a major part in ensuring good indoor air quality, which is vital for human health.” www.hpmmag.com August 2016 The new Kingspan Albion Ultrasteel Plus range includes a solar indirect model in four different capacities ranging from 180 litres to 300 litres to suit properties of any size and for use with any solar thermal hot water system. Installers should be talking to their customers about the benefits of stored water and solar power as the world's most reliable hot water source. The Ultrasteel name is already trusted by installers and homeowners alike for its outstanding quality and high performance levels, which the premium Plus series enhances with added installation and design features. With proven advantages of hybrid domestic systems that combine renewable and fossil fuel technologies to achieve significant all year round cost savings on hot water supplies, most sealed systems can be adapted to incorporate solar power and equally, a new solar cylinder can be installed in anticipation of future system conversion to renewable energy. This solar indirect unvented hot water cylinder features a built-in thermal expansion space, eliminating the need for an external expansion vessel, resulting in a faster, simpler installation with a reduced risk of call back. The cylinder has two heating coils, with the primary coil connecting to a solar thermal system and the secondary coil connecting to a boiler, which is used to top up hot water supplies when necessary. It also has a 3 kW immersion heater fitted for back-up heating. Every cylinder comes with a 25-year guarantee against faulty materials or manufacture and a twoyear guarantee on all components supplied with the cylinder. Grant has introduced a new ErP A-rated cylinder to its high efficiency heat pump cylinder range. The new Grant MonoWave 200 litre model is designed to maintain temperature for longer, due to its higher levels of insulation. The new Grant MonoWave A-rated heat pump cylinder is a single coil indirect model offering incredibly high energy efficiency for homeowners. When installed alongside the Aerona³, a combined energy efficiency rating of A++ (heating) and A (hot water) is achieved. Furthermore, when installed as part of package, for example with an Aerona³ heat pump and a Grant Solar Thermal kit, an ErP package rating of A++ can be reached. To complement the Aerona³, Grant now has a total of 13 cylinders within its Wave product range which are specifically matched to the inverter driven heat pumps. Being manufactured from duplex stainless steel, the cylinders have a larger primary coil, which allows for the heat to be transferred quickly and effectively. With indirect single coil and twin coil versions available, Grant’s heat pump cylinder range allows for easy installation for engineers, while also offering the option of combining an additional heat source.
