The Greenstar Heatslave II series is the UK’s most popular external oil-fired combi boiler. With a range of models available, making it suitable for small, medium and large sized properties, the boiler features a robust IP45 weatherproof cabinet to protect from the weather and a one piece stainless steel primary baffle for rapid servicing and maintenance.
The Grant Vortex Pro outdoor combination oil boiler features internal frost protection, a 24 litre expansion vessel, neon diagnostic indicators and a factory-fitted condensate trap, together with the conveniently factory-fitted, multi-directional flue - and all of this has been designed to make installation and servicing easier. With larger than normal heat exchangers, the hot water performance of this high-efficiency combi boiler is vastly increased. The two very accurate electronic temperature controls allow the boiler to operate in condensing mode on central heating and instant hot water production can be maintained.
The Greenstar Danesmoor External is designed for open vent heating systems and is ideal for small, medium and large sized homes that include stored hot water. Inspired by installer feedback, the boiler has been designed to make installation and servicing easier, whilst also featuring easy to remove one-piece primary baffles. A robust IP45 rated cabinet protects the boiler from the weather.
