  • Small footprint – get over 1MW from less than 1 metre squared footprint
  • Aluminium heat exchanger provides excellent heat transfer properties and a 5-year warranty
  • Quick to respond with low water content
  • Lightweight and compact – ideal for city centre developments
  • Parallel water flow for an even surface temperature across the aluminium heat exchanger
  • Highly efficient up to 97% gross seasonal efficiency exceeds legislation and reduces energy use
  • High turndown ratio for close load matching further improves efficiencies
  • Assists designers with changing project requirements - gas and water connection positions identical on all models
  • Easy access for service and system cleaning – combustion analysis and drain point at front of boiler
  • Built in boiler sequence controls capable of controlling up to 16 boiler modules and hot water circuits
  • Low noise to enable installation close to building occupants
  • Environmentally friendly low NOx emission (European Class 6)
  • 6 bar rated heat cell
  • Air inlet filter for clean combustion and reduced noise
  • Simplified primary circuit design with a choice of complete optional kits from Hamworthy to include – flow and return pipework kit, optional matched boiler pumps, low loss header with combined air and dirt separator, connection points and manifold extension kits.
  • Shortlisted for H&V News Award 2018 - Commercial HVAC product of the year
