Worcester-Bosch Greenstar 30CDi

The Worcester-Bosch Greenstar 30CDi is a compact stylish gas-fired boiler suitable for medium or large households. It can be mounted on the wall of an airing cupboard or a kitchen and being a combination or "combi" boiler the Greenstar 30CDi provides instant hot water on demand. This means that the use of hot water – for showering, for example – need not be limited by the capacity of the hot water cylinder in your home.

Furthermore the Worcester-Bosch Greenstar 30CDi boiler employs what is known as "modulating control" to provide highly energy efficient central heating without consuming gas unnecessarily. The gas supply to the boiler burner "modulates" according to the demand for heat in your home. Although this means that the Greenstar 30CDi is "on" for relatively long periods its operation is at a low level. This is actually more economical than an appliance that continually switches "on" and "off". During long periods of inactivity – during the summer months for example – the Worcester-Bosch Greenstar 30CDi activates its system pump once in every 24 hour period to prevent seizure.

The full specification and product details of the Worcester-Bosch Greenstar 30CDi are as follows:

  • 30kw DHW ("Domestic Hot Water") output
  • SEDBUK ("Seasonal Efficiency of Domestic Boilers in the United Kingdom") "A" rated for energy efficiency
  • Compact dimensions of H760mm x W440mm x D360mm
  • Environmentally friendly with regard to carbon dioxide (CO2) and nitrogen oxide (NO x) emissions
  • No exposed pipework
  • Simple, easy to use timing controls which can be set week by week or for weekdays, weekends or individual days
