Our P Series is a range of three-pass cast iron sectional boilers perfect for use with gas, light oil, dual fuel and bio-fuel through a pressure jet burner for commercial and industrial applications. Designed on the basis of the triple-pass principle to achieve maximum efficiency, the generously-sized chamber provides for optimal combustion and minimum NOx and CO2 emissions.

Compact yet extremely powerful, the P Series is available in two ranges: P420 and P520 (the P320 suitable for replacement projects only).

Due to changes in ErP regulations, from 1st January 2018, non-condensing Pressure Jet boilers replacements below 400kW can no longer be installed. So that we can be compliant with this regulation change, we won't be able to take orders for the P-Series P320 range and the P420-8 after 31st October 2017.

There are lots of options available to replace these products that are both highly efficient and compliant. Take a look at our other product ranges or speak to your Area Sales Manager who will be able to advise on the range of solutions available

  • High combustion efficiency - Higher than average energy savings
  • Triple-pass flueways design - Maximises efficiency
  • Large combustion chamber - Minimises NOx and CO2 emissions
  • Eutectic cast iron boiler body - Provides exceptional resistance to temperature variations, thermal shocks and corrosion
  • Reinforced fibreglass wool insulation and double insulation of boiler front - Minimises heat loss for improved thermal efficiency
  • Easy installation for new and existing plant rooms - Time saving
  • P520 is delivered as standard with pre-set water flow switch - Quick and easy installation
