What Makes the Worcester Bosch 36CDi Stand Out?
The Greenstar 36CDi Compact delivers impressive specifications for larger households. With a hot water output of 36kW and a 12.9 litres per minute flow rate, this boiler meets the demand of multiple bathrooms simultaneously.
Picture morning routines where two showers run while someone fills the kitchen sink. The 36CDi manages these situations without dropping water pressure or temperature. The safest option is to consult a trusted boiler installation service and get their advice.
Compact Design
Despite its power, this Worcester Bosch combi boiler fits into standard kitchen cupboards. The dimensions are 690 x 390 x 280 mm, and the weight is 36kg. You won't need a dedicated boiler room. The unit mounts on walls or tucks neatly into existing cabinets, freeing up valuable space in your home.
Worcester Bosch also offers the Greenstar 8000 Style range in high gloss black or white finishes if you prefer a boiler that looks good on display.
Energy Efficiency: How Much Can You Save?
The Worcester Bosch 36CDi Compact achieves an ErP rating of 92%, earning an A rating on the efficiency scale. This rating is based on rigorous testing and provides a reliable benchmark for comparing different models.
Why Efficiency Matters
An efficient boiler can reduce your monthly energy bills significantly. A new A-rated combi boiler could save you up to £800 annually compared to older, inefficient models.

Worcester 36CDi Boiler Usability and Controls
Modern boilers need intuitive controls that give you flexibility over your heating. The Greenstar 36CDi meets Boiler Plus regulations introduced in 2018, which require enhanced control options.
Smart Thermostat CompatibilityThe 36CDi works with smart thermostats, allowing remote control through smartphone apps. Wherever you are, you can change the temperature, plan heating schedules, and keep an eye on your energy consumption.

Smart controls offer real convenience. Heading home early? Turn the heating on remotely. Away for the weekend? Adjust your schedule to save energy.
Manual ControlsIf you prefer traditional controls, the boiler includes a clear display panel behind the front flap. Large buttons let you adjust temperatures, switch between modes, and check for warning lights. Everything is clearly labelled, and the included manual provides detailed instructions. We found the interface straightforward and easy to navigate.
