Grant has introduced a new ErP A-rated cylinder to its high efficiency heat pump cylinder range. This new Grant MonoWave 200 litre model is designed to maintain temperature for longer, due to its higher levels of insulation.
It is a single coil indirect model designed to offer high energy efficiency for homeowners. When installed alongside the Aerona³, a combined energy efficiency rating of A++ (heating) and A (hot water) is achieved. 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.
The company now has a total of thirteen cylinders within its Wave product range which are specifically matched to the inverter driven heat pumps. 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, the heat pump cylinder range aims to make installation easy for engineers while also offering the option of combining an additional heat source.
