The Worcester 8000 F DHW Solar Pre Heat Accessory is an add-on component designed for Worcester Bosch Greenstar 8000 F combi boilers. Its main purpose is to allow the boiler to work with pre-heated domestic hot water (DHW) from renewable sources like solar thermal systems.

Key Features & Benefits

• Compatibility: Works with Greenstar 8000 F combi boilers.
• Function: Enables the boiler to accept water that has been pre-heated by solar thermal or other renewable systems.
• Efficiency: Reduces gas consumption because the boiler will modulate down or may not fire at all if the incoming water is already hot.
• Temperature Limit: The maximum pre-heated water temperature should be 55°C.

Why Use It?

If you have a solar thermal system or another renewable heat source, this accessory integrates them with your 8000 F combi boiler, improving energy efficiency and lowering running costs.
