Grant expands renewable offering with launch of new AWave Integrated Unit

With helping to achieve zero carbon emissions across Ireland a key priority, the R&D team at Grant is continuously finding new and innovative ways to maximise the sustainable attributes of all Grant heating technologies. This includes the most recent addition to the company’s diverse product range – the AWave integrated Unit – a new highly sustainable hot water storage unit which will be available later this year.    

This new 210 litre hot water storage unit stands at 1.8 metres high and with a footprint of 630 x 695mm can be installed neatly within domestic spaces of a property. Grant’s range of Wave hot water cylinders are manufactured from high grade duplex stainless steel and are indirect, mains water cylinders. The new high gain 210 litre capacity single coil AWave Integrated Unit has a solid, stainless steel coil which will lead to a much faster heating time and quicker recovery. In addition, the AWave Integrated Unit will save installers valuable installation time as it has been pre-plumbed and pre-wired.

Grant AWave Integrated Unit

The Grant AWave Integrated Unit has been manufactured for a domestic hot water zone that allows hot water priority and a two-zone heating, with an option for a third heating zone. Both the heating and potable heating vessels are included within the unit. The AWave is also designed with the service engineer in mind when it comes to ease of maintenance and service.

Like with other Grant heating technologies, the new AWave Integrated Unit has been developed to work seamlessly with other products within the Grant range to maximise efficiencies. When paired with any model from the Grant Aerona3 R32 air to water air source heat pump range, efficiency levels can be taken to new levels and homeowners can benefit from a complete heating solution featuring two highly sustainable heating technologies which they can depend on for many years to come.  

Grant’s A+++ Aerona3 R32 air to water air source heat pump is the manufacturer’s most sustainable main heat source and has risen in popularity in recent years due to its high efficiency levels. The Aerona3 is available in four outputs of 6kW, 10kW, 13kW and 17kW and benefits from a cleaner, more environmentally friendly performance. The Grant Aerona3 R32 air to water air source heat pump range is also capable of lowering a property’s overall carbon footprint, which will ultimately help to achieve NZEB building standards.

All four models within the Grant Aerona3 R32 range also boast superior seasonal coefficient of performance (SCOP) and depending on climate conditions and demand on the heating system at the time, can deliver 4kW of heat energy for every 1kW of electricity used. Units within the range can also achieve an A+++ energy rating at low temperatures such as –20°C, which further demonstrates Grant’s commitment to providing market-leading heating solutions.

When installing a Grant AWave Integrated Unit with a Grant Aerona3 R32 air to water air source heat pump, it’s very important that the unit has been correctly sized to ensure the hot water needs of the property are fulfilled. To ensure a heating system is sized correctly, those in the trade can avail of Grant’s free of charge heating design service which enables Grant’s technical specialists to size and specify the most efficient heating system for the individual property, helping to save vital time for those working on a new build or deep retrofit project.

When carrying out the heating design process, the Grant technical team will also ensure that compliance - the EPC (energy performance co efficient) and the CPC (carbon performance co efficient) - are met for the BER assessor, engineer or architect.
