Worcester-Bosch Greenstar 40CDi Conventional

The Greenstar 40CDi Conventional is the most powerful of a range of highly energy efficient conventional boilers available from Worcester-Bosch. The Greenstar CDi range was awarded "Boiler of the Year" by CORGI ("Council for Registered Gas Installers") in 2007. The Worcester-Bosch Greenstar 40CDi Conventional offers outputs of between 9.4kW and 40.8kW to domestic hot water and central heating but is, nevertheless, 90.2% energy efficient and rated "A" for energy efficiency according to SEDBUK ("Seasonal Efficiency of Domestic Boilers in the United Kingdom") figures.

On demand for domestic hot water or central heating the electronic control system of the Worcester-Bosch Greenstar 40CDi Conventional ignites the boiler burner and adjusts the flame to a set level defined by the separate consumer controls. If the flow temperature exceeds the set level at any time the control system "modulates" the burner downwards to the correct level but also employs "anti cycle" protection to disable the burner temporarily if the temperature continues to rise.

Key features and product details of the Worcester-Bosch Greenstar 40CDi Conventional include:

  • 90.2% energy efficiency
  • Low carbon dioxide (CO2) and nitrogen oxide (NOx) emissions
  • Horizontal and vertical flue options including 45° or 90° bends for flexible installation
  • Wall mounting frame requires no additional wall spacing assembly and leaves no pipe work exposed
  • Available in natural gas and LPG ("Liquified Pertroleum Gas") variants
  • 2 year parts and labour warranty – extending to 10 years for primary heat exchanger – subject to regular inspection and servicing
