The Grant Vortex Outdoor Combi 26kW is a floor standing, oil fired condensing boiler designed for external installation. It provides both central heating and mains pressure domestic hot water without the need for a separate hot water cylinder, making it suitable for locations where internal space is limited.
This model operates using Class C2 kerosene and incorporates condensing technology to maximise energy efficiency. It features a Riello RDB burner, a 24 litre expansion vessel, and a factory fitted multi-directional flue system with optional side or rear exits for flexible installation. The unit includes fully valved flow, return, and cold feed connections for complete system isolation during servicing.
Built to comply with current Building Regulations and low NOx requirements, the boiler achieves a seasonal efficiency rating of 92.2% and carries an ERP ‘A’ rating for heating. It is supplied with a drop down control panel for easy access and servicing, and requires commissioning at installation to ensure optimal performance.
