Grant Vecta: External

The high efficiency Vecta external condensing biomass boiler is the perfect choice when space is limited within the home and homeowners are looking to reduce heating bills and take advantage of the financial incentives under the Domestic RHI.

The external Vecta is very similar to the internal Vecta but has some additional unique features including high quality external powder coated paint finish, built in frost protection and conventional flue system connection.

Features & benefits

  • *5 year guarantee when installed by a G1 installer. Subject to T&C's
  • Fitted with Weather compensation and Lambda Sensor- The appliance can cleverly monitor the outside temperature and adjust the system water temperature to match a heat output closer to the needs of the home, thereby using less fuel and making the whole heating system more efficient.
  • Automatic pellet feed and ignition
  • With a 60kg top fill integral pellet hopper the Vecta is designed to be bag filled. Having no separate hopper means that the boiler is not only compact but far more versatile when it comes to siting. Alternatively, there is also the option of utilising a bulk store and vacuum system which will automatically fill the integral hopper for convenience.
  • The Vecta External is also available with an optional bolt on store which can increase the combined pellet storage capacity. The store has a powder coated stainless steel casing (Part Code: WVP4/16EXTSTORE) has a capacity of 140kg and fits to the right-hand side of the boiler only.
  • The Vecta benefits from a self-cleaning function that periodically cleans the burner and heat exchangers reducing the need for regular maintenance other than emptying the ash pan.
  • Routine servicing is straight forward with the burner and heat exchanger being easily accessible from the front of the boiler. This is required when the control due, or after 12 months, whichever comes first.
  • Nett efficiency of 90.6% (reduced load) up to 94.8% (full load)
