Worcester Bosch Greenstar Danesmoor Utility System Oil Boiler 12/18–25/32kW
The Greenstar Danesmoor Utility System is Worcester Bosch's compact internal oil condensing system boiler for sealed heating systems with stored hot water (including unvented cylinders). The pump and expansion vessel are built in, so no separate feed and expansion tank is needed.
Key points
- Outputs 12/18, 18/25 and 25/32kW (2022+ models)
- 855 x 370 x 600mm (H x W x D), IP20, ErP A
- Integrated pump and expansion vessel; fits under a worktop (worktop must be removable)
- EasyControl and solar compatible; HVO conversion kits available from Worcester
- Room-sealed Oilfit 80/125 flue (up to 5-6m horizontal, 8m vertical) or conventional flue
Required with this boiler: a flue kit
Worcester Bosch supplies this boiler without a flue. The Flue kit selector above Add to cart adds the Greenstar Oilfit 80/125 standard telescopic flue kit (460-670mm, 7716190064) by default, as a separate line in your basket. Pick the short telescopic kit (360-460mm) for thinner walls, or the Oilfit 80/125 vertical flue kit for a roof exit.
Only choose "I already have this" if you already have a compatible Oilfit flue, or the boiler is going onto a conventional (open) flue. Check maximum flue lengths and terminal positions in the installation manual.
What's included
- 1 x Worcester Bosch Greenstar Danesmoor Utility System oil boiler in the output you select
- Hardware pack, ErP label and literature, as supplied by Worcester Bosch
- No flue included: choose your flue kit with the selector above Add to cart

Installation and guarantee
Installation must be by a Gas Safe registered engineer (oil: OFTEC registered) and commissioned with the Benchmark checklist. Manufacturer guarantees require registration after installation and annual servicing; extended guarantee terms are the manufacturer's and may require their approved filter/installer.
Oil installations also need a correctly sited tank and oil supply line with filter, isolation and a remote-sensing fire valve, to BS 5410 and Building Regulations. Unvented cylinders need G3 installation. Worcester Bosch's current UK product page quotes up to a 7 year guarantee (2 years standard; longer terms need a Greenstar System Filter and Worcester's registration terms).
Delivery and collection
Delivered by pallet/courier (£29.99 per order) or collect free from Leafbridge, Lincoln. Order-in boilers usually 2-4 working days.
