Editor, Juliet Loiselle, and Sales Manager, Victoria Brown were invited to view the installation of the Palladium Hydrocarbon Heat Pump at Greenpeace HQ in London.
Greenpeace, has made a real statement of its commitment to sustainability by installing this Propane (R290) Heat Pump at its 1920s office building in Islington North London. The new Palladium 85kW Palladium 120.4 unit, manufactured by the Italian company Enerblue, provides both space heating and hot water to the main office building replacing its old gas boiler. This installation marks the UK launch of the Ultra Low Noise Palladium range of R290-based heat pumps, designed for commercial and industrial applications.
Why was this installation important to Greenpeace?
Greenpeace want to continue to be ahead of the curve when it comes to clean energy. So much so, that they even invited 12 Labour members of parliament as dinner guests the week before our visit. The Greenpeace team were very proud to show off their new Heat Pump and explain how the Government needs to invest around 2.5 billion, to help consumers afford and make the best decisions with renewables – this is paramount to achieve 2025 Net Zero targets.
The 1920s building was previously used as an industrial site. In fact; it housed animal testing laboratories, something which is not lost on Greenpeace. This enormous retrofit project was part of a long-term plan for Greenpeace. Starting in 2010 they started to reduce building related C02, adapting the building fabric helped, as did the migration of their servers across to the cloud. Highefficiency lighting was installed and even EV charging is now a fleet requirement. The final piece for this particular plan was sourcing the best way to create cleaner and greener energy.
After much monitoring of their current usage, and many investigations into their existing heating and hot water systems they agreed with Pure Thermal that the Palladium Hydrocarbon Heat Pump was their best option.
Tick boxes for their air source heat pump requirements;
- Ultralow noise - Due to being set within a highly residential area in the middle of London
- Retrofit suitable – Meaning sensitivity to the fabric and existing systems of such an old building
- High temperature output – With a highly populated office hot water was paramount
- Natural non F-Gas considerations – Hydrocarbon Refrigerant was the best option
“This project is a great example of a hydrocarbon heat pump providing high performance and resilience in a commercial application located within a residential area in central London,” said Garry Broadbent of Pure Thermal.”
The defrost strategy is one which will not allow any degradation of output temperature whilst the heat pump is in defrost mode. Even with providing irrigation for the garden post the defrost cycles – very clever!
