Grant has expanded its Aerona³ air source heat pump (ASHP) range with the launch of a 12kW model which is the company’s greenest heat pump yet.
The Aerona³ 12kW R32 inverter driven ASHP is the latest model to join Grant UK’s renewable product range. The heat pump achieves an ErP rating of A++ and it is said to be the first monoblock R32 air source heat pump to be launched in the UK.
The introduction of the heat pump is said to be in response to the growing demand for products which have a lower impact on the environment. The 2014 EU Fluorinated Greenhouse Gas (F-Gas) Regulations have been introduced to phase out the use of hydrofluorocarbons. A series of targets have also been implemented which have been designed to limit the use of gases which have the highest Global Warming Potential (GWP).
Grant’s Aerona³ 12kW boasts a GWP which is considerably lower than other typical heat pump refrigerants such as R410 and will therefore comply with the upcoming legislative targets.
In addition to having a lower GWP figure of 675, R32 is a single-component refrigerant which means it has no temperature glide. Refrigerant blends that have two or more components exhibit temperature glide but as R32 only has one molecule in its formation, its saturated liquid and vapor temperatures are the same. By removing the risk for the refrigerant to suffer from glide, the system can recharge and recycle with greater ease, making it more efficient.
The new model is a single phase, DC inverter driven ASHP and includes features such as in-built weather compensation and a base tray heating element to prevent ice formation. The Aerona³ R32 is also suitable for use with S-Plan heating control systems.
