Improved PRV access

The PRV is situated at the front, after easily pulling down on the PRV clip with a screwdriver, removing it couldn’t be any more straightforward.

Primary Heat Exchanger

Primary Heat Exchanger

With a 10 year guarantee* as standard, the C6 heat exchanger is an evolution of our tried and tested WB3 heat exchanger from the Greenstar i.

  • Improved modulation decreases gas consumption, cuts energy bills and reduces component wear and tear through lower fan speeds.
  • Access to burner and heat exchanger baffles via just one screw and one bolt.
  • A clearly marked, green-capped fan pressure test point.
  • For easy cleaning, maintenance and inspection, an access hatch is built into the bottom of the heat exchanger.
