Easier servicing – access all areas

Ease of servicing was always at the forefront of the Greenstar 4000’s design.

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

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.
