About this boiler pack

Worcester Bosch WORCS GS 8000+ 40KW COMBI, V FLUE & FILTER is a combi boiler pack from Worcester Bosch. 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.

A combi boiler supplies central heating and heats domestic hot water on demand, normally without a separate hot-water cylinder. This listing specifies 35 kW maximum condensing central-heating output. Its domestic hot-water output is 40 kW. The listed hot-water flow is 17.1 l/min at a 35°C temperature rise. Heating demand and hot-water demand must be assessed separately; incoming water flow and pressure affect tap and shower performance.

Listed casing dimensions are height 780mm, width 440mm, depth 365mm. 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 Greenstar 8000+. 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.
