VortexBlue Range – Combi Models

The intelligent VortexBlue Combi incorporates the latest Riello RDB Blu burner technology teamed with our award winning Vortex stainless steel heat exchanger. The Grant VortexBlue Combi models are available as internal or external in three sizes: 21kW, 26kW and 36kW.

Featuring large heat exchangers which, due to their low water content and larger surface area, vastly increased the hot water performance. With a low system pressure cut off switch, the combi protects itself in the unlikely event of system water loss. Additionally, there are two very accurate electronic temperature controls which allow the boiler to operate in condensing mode on central heating whilst maintaining its instant hot water production.

Features

  • Award winning Vortex condensing heat exchanger
  • Market-leading Riello Blue Flame burner
  • 10 year guarantee when installed by a G-One accredited installer*
  • 24ltr expansion vessel
  • Neon diagnostic indicators
  • Factory-fitted internal condensate trap (which can be sited externally)
  • External combi models also benefit from a factory-fitted multi-directional flue, high quality external powder coated casing, built-in frost protection, mains isolating switch and a test switch
