Grant Vortex Eco Kitchen/Utility Boiler 15/21Kw

  • 5-year guarantee when installed by a G1 accredited installer
  • Unlike traditional oil-fired boilers the Grant Vortex condensing boiler has a built-in stainless-steel heat exchanger incorporating our unique turbulator baffle system which cools the gases to a point where the latent heat, normally lost to the atmosphere through the flue, can be usefully extracted. The additional energy recovered enables the boiler to operate continuously at much higher efficiency levels, resulting in lower heating and hot water running costs.
  • Exceptionally quiet operation
  • All Grant Vortex boilers are easy to install and can either be connected to a conventional ‘stainless steel’ flue or one of Grant’s EZ-Fit flue options using an existing chimney.
  • The 15-21 utility model has been designed to fit within a kitchen unit and, due to its reduced width, can be used as a direct replacement for most older oil-fired boilers.
  • Unit size: 855mm(H) x 348mm(W) x 566mm(D)
  • Max Output: 21Kw 
  • Weight: 97Kg
  • Part Number: VTX15-21
