  • Horizontal Cylinders with 2 ImmersionsDual immersion heaters enable horizontal models to be used as a direct cylinder when required — not just indirect
  • 50mm High InsulationFactory-fitted 50mm PU foam insulation minimises standby heat losses and improves energy efficiency throughout the cylinder’s working life
