1.0 The Net Zero Pod (NZP)
The Net Zero Pod is the leading solution for transitioning to net zero facilities.
• An innovative and pioneering application of heat pump and green technology.
• An acoustic Packaged Plant Room for better quality control and ease of installation / commissioning. Designed and built off-site at the Leisure Energy Technology Centre.
• Natural Refrigerant (CO2) with a Global Warming Potential (GWP) of 1.
• Capable of delivering sCOP’s of 4+.
• Range of Heat Pump sizes available (for example: 2x250kw / 2x 150kw) suitable for leisure and other buildings.
• Significantly more efficient with lower running costs – compelling ROI and better value for money.
• 50°C and 75°C (up to 90°C) flow and return circuits as standard.
• Chilled circuit upgrade available – for “free” cooling Studios, Gym, Soft play etc.
• Making decarbonisation affordable and uniquely suited to Swimming Pools in particular.
• Smart building management – accessing off-peak utility tariffs.
• Funded solutions available linked to maintenance / service package underpinned by a Performance Warranty – breaking the link and reliance on grant funding.
