Greenline R290 air source heat pumps
It’s what you see first is their outer casing, and we really like the robust casing round these Greenline R290 heat pumps. Made from recycled plastic they are thick, and made to last. After all a heat pump will heat a home for many many years and it’s the outer covering that needs to take the brunt of the UK weather.
Access for electrical connections is easy - a couple of screws and you can gain entry via the side to the connections you need. This speeds up installation saving time, money, and hassle.
Every so often a heat pump defrosts ice that forms on it in winter - this is totally normal and happens a little more often in the UK than much of Europe because we tend to have more humid air. Often a tray is fitted under a heat pump (called a condensate tray) to catch it all so it can then be lead off to a drain. With Greenline heat pumps this water already comes out of a single pipe which you can then lead to a drain or soakaway - again saving time and expense.
Wifi/4g connectivity comes as standard and we highly urge everyone to take up the option of remote management - this system is a yearly charge and sends automatic alerts to both the installer and homeowner to let them know about any potential issues, and lets the engineer make fixes and changes to settings remotely. This speeds up response times, reduces callouts, saving time, hassle and inconvenience.
R290 refers to the refrigerant that these heat pumps use. There is a move happening across Europe and in the UK over to using natural refrigerants. R290 is propane, as is already used in some of our fridges inside our homes. The reason for the change is that these gases have a lower impact on global warming.
We tend to design our heating systems to low maximum flow temperatures - around 35-40º - to improve efficiency and keep running costs low. However Greenline heat pumps can run up to 75º, which can be ideal for use in conjunction with a thermal store and a time-of-use electricity tariff, letting you store up a lot of cheap heat for use later on. This also means that no immersion element is required to complete the weekly legionella disinfection cycle.
The three single-phase models in the range have a very good spread of heat outputs, suitable for the vast majority of domestic properties (and when high heat outputs are needed then there are three-phase Greenline units available, up to 60kW).
Heat outputs at -5º outside and at 45ºC flow temperature are 5.5kW. 10.76kW, and 16.53kW respectively for the single fan Greenline 100 and 200, and the double fan 300 model.
