Weather compensation

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. In fact, the system will adapt before it even feels too cold or too hot.

Filling the Vecta’s hopper

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.

Internal Side Pellet Store

The Vecta Internal is also available with an optional bolt on store which can increase the combined pellet storage capacity. This white cased side store (Part Code: WVP4/16STORE) has a capacity of 140kg and fits to the right hand side of the boiler only.

The store’s hinged lid with gas struts allows for top fill. Coming complete with a feed auger and cable, the combined pellet storage capacity of the side store alongside the boiler becomes 200kg.


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.
