About this boiler pack

Vaillant EcoFit Pure 615 15kW System Boiler with Horizontal Flue Pack is a system boiler pack from Vaillant. The inclusions below describe this bundle; a different flue, filter or control option is a separate pack, even when the boiler model is the same.

This system boiler provides central heating and can heat domestic hot water through a separate compatible cylinder; it does not provide the instantaneous tap flow of a combi. The listed maximum condensing heating output is 15.9 kW. A system boiler typically incorporates the heating pump and expansion vessel, but the exact model and cylinder arrangement must be checked. A cylinder is not assumed to be supplied in this pack.

Listed casing dimensions are height 700mm, width 370mm, depth 295mm. Allow additional installation and servicing clearances specified in the model's manual; casing dimensions alone do not confirm cupboard suitability or an acceptable flue route.

The verified pack inclusions are listed below. Do not assume additional filters, controls, cylinders or flue extensions are included. An installer should confirm that the selected flue and controls suit the property, fuel supply and manufacturer's requirements.

The displayed pack price is for supply, not installation. Gas work must be undertaken by a suitably qualified Gas Safe registered engineer. BritOne Air can arrange a separate installation quote through UK Gas Plumbers Limited; commissioning, water treatment, controls and any changes to the existing system are assessed as part of that quote.

Manufacturer warranty and extended cover are explained separately below for ecoFIT pure. The advertised family term is not confirmation of this pack's entitlement: the exact model generation, registration route, filter and service requirements must be satisfied. Accessories may have their own warranty terms.
