Worcester-Bosch Greenstar 30CDi Conventional
The Worcester-Bosch Greenstar 30CDi Conventional is a wall mounted gas fired conventional – also known as "heating only" – boiler. The appliance combines a cast aluminium heat exchanger, fan and pressure release valve in a single unit but feed and expansion cisterns in your loft and a hot water storage cylinder are also required. Indeed, the capacity of the hot water storage cylinder largely determines the availability of hot water within your household. Typically, however, the Worcester-Bosch Greenstar 30CDi Conventional is suitable for installation in small or medium-sized households with traditional central heating and domestic hot water systems. Such systems may benefit from the reduced pressures associated with the Worcester-Bosch Greenstar 30CDi Conventional in comparison to a "combi" (combination) or system boiler.
The key features of the Worcester-Bosch Greenstar 30CDi Conventional are as follows:
- 90.3% energy efficient and therefore rated "A" for energy efficiency by SEDBUK ("Seasonal Efficiency of Domestic Boilers in the United Kingdom")
- Maximum 30kW, or 102,260Btu ("British Thermal Units") per hour, output for domestic hot water and central heating
- Low carbon dioxide (CO2) and nitrogen oxide (NOx) emissions so environmentally friendly
- Compact dimensions (H760mm x W440mm x D360mm)
- Robust aluminium and silicon heat cell
- Integral frost protection and fault finding diagnostics
- Automatic adjustment of gas pressure
- Combination ignition and control board means fewer connections are required
- Horizontal or vertical fluing system, for 100mm or 125mm diameter flue, and supplied flow and return pipes allow installation to be flexible and neat with pipes behind the installation rather than exposed
