Worcester Bosch Danesmoor System Utility 18/25 Boiler 7731600152
The Worcester Bosch Greenstar Danesmoor System Utility 18/25 (Part Number: 7731600152) delivers quiet, efficient, and dependable heat from inside your home. Built specifically for kitchen, utility room, or garage positioning, its clean white casing and compact dimensions blend discreetly with modern appliances. Because it is a complete system boiler, the primary circulating pump and expansion vessel are pre-assembled inside the unit, eliminating the need for header tanks in the attic. Delivering an adjustable 18kW to 25kW output, this ErP A-rated oil boiler pairs with an unvented cylinder to deliver fast radiator heat-up times and constant high-pressure hot water.

Grant EZ200B Flue Kit 26-70KW (inc Terminal Guard) Black
The Yellow system has been developed to make the installation of Grant boilers both quick and simple, whilst ensuring trouble free operation, even in the most exposed site conditions.
The round low level kits feature self-sealing ducts requiring no silicone or tape for joints, and the unique quick-fit clamp arrangement ensures a perfect seal every time. In fact, the new telescopic flue system requires only two simple operations to complete the installation. The kits are compatible with all Grant boilers, (except Outdoor Modules) including condensing models.
The flue terminal has a compact design, making it ideal for installations where the visual appearance is important. The new cone design reduces the possibility of condensate, produced in the combustion process, staining external wall surfaces or patio slabs
