The Worcester Bosch Greenstar 8000+ 35kW Heat Only Boiler is a wall mounted, gas fired condensing boiler designed for medium sized heating systems. As a heat only (regular) boiler, it requires a separate hot water cylinder and cold water storage tank, making it suitable for properties with moderate hot water demand.
This model provides a central heating output of 35kW and operates on natural gas, with LPG compatibility available. It achieves an ErP A rating with a seasonal efficiency of 94%, meeting current energy standards. The boiler is also hydrogen ready for a 20% hydrogen blend, supporting future low carbon energy transitions.
Key features include a full colour touchscreen display, rear piping connections, and an Intelligent Filling System that automatically maintains system pressure. It supports smart thermostat connectivity for remote control and monitoring. The unit measures 780mm high, 440mm wide, and 365mm deep, with a lift weight of approximately 42kg.
