Grant Vecta: External

The high efficiency Vecta external condensing biomass boiler is the perfect choice when space is limited within the home.
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.
The unit is also available with an optional bolt on side store which can increase the combined pellet storage capacity.

This weatherproof outdoor module is the perfect choice  when space is limited within the home.

Our external Vecta is a popular addition to the Grant condensing wood pellet boiler line up. It is a perfect option for rural homeowners looking to reduce heating bills and take advantage of the financial incentives under the Domestic RHI.

External Side Pellet Store

The Vecta External is also available with an optional bolt on store which can increase the combined pellet storage capacity. This side store has a capacity of 140kg and also has a powder coated stainless steel casing. The store (Part Code: WVP4/16EXTSTORE) fits to the right hand side of the boiler only and has a hinged lid to allow top fill.

Coming complete with a feed auger and cable and supplied with a weather proof external flue system inspection pipe, the combined pellet storage capacity of the side store alongside the boiler becomes 200kg.
