The Grant Vortex Pro Internal Combi 26kW Oil Boiler is a high-efficiency, internal combination boiler designed for homes not connected to the gas grid. It uses oil as fuel, ideal for rural areas. The 26kW output is suitable for medium homes. As a combi boiler, it provides both heating and hot water from a single unit, eliminating the need for a separate hot water cylinder or tank. The Vortex Pro series focuses on high efficiency to reduce fuel consumption and heating costs. It employs condensing technology to extract more heat from exhaust gases, increasing efficiency and reducing environmental impact. Key features include a 24-litre expansion vessel, neon diagnostic indicators, a factory-fitted condensate trap for easier installation and servicing, and larger than normal plate heat exchangers for vastly increased hot water performance. It has two accurate electronic temperature controls, a low system pressure cut-off switch for protection, and is simple and quick to install with no complicated wiring or plumbing. Its compact design makes it suitable for kitchen installations. It features a Riello RDB burner with plug and socket connection, a high-efficiency circulating pump, and a Grant Vortex stainless steel heat exchanger. It offers multi-directional flue options and achieves a SEDBUK SAP 2009 ‘A’ rating, being registered with the Energy Savings Trust. It also comes with a 2-year guarantee.
