Worcester Bosch Greenstar Danesmoor External 12/18 System Boiler

The Greenstar Danesmoor External 12/18 is a highly reliable condensing oil system boiler, manufactured by Worcester Bosch, that has been designed for outdoor installation.

How efficient is the Greenstar Danesmoor External 12/18?
This is a highly efficient boiler as shown by the efficiency rating of 90% and ErP A-rating which means that it could help to lower your carbon footprint and your energy bills.

Is an 18 kW output rating suitable for my home?

A system boiler with an output rating of 18 kW is best suited to a home with 1 bathroom and around 15 radiators.

Does the Greenstar Danesmoor External range include any other output ratings?

The Greenstar Danesmoor External is available in 3 models and this 12/18 unit features the lowest of these outputs. Additional outputs in the range include 25 kW and 32 kW.
Is a system boiler suitable for my home?

System boilers are perfect for homes with a higher demand for hot water as they store hot water in a cylinder. As a result, there must be enough room in your home for the boiler and cylinder to be installed.

How long is the warranty?

Worcester Bosch have attached a standard 2 year warranty to the Greenstar Danesmoor External 12/18 which can be extended to 5 years when certain terms and conditions are met.

What are the key features of the Danesmoor External 12/18?

Danesmoor External boilers have a number of features that allow them to run efficiently and reliably. Some of the features include frost protection which protects it from freezing during cold winter temperatures and compatibility with solar technology.

As an external boiler, it’s essential that it’s well protected and the green powder coated cabinet does just that, as well as almost camouflaging the unit with its outdoor surroundings.

How big is the Danesmoor External?

The Greenstar Danesmoor External 12/18 has been designed for installation in an outdoor area, such as a garden. Its dimensions of 950 x 565 x 780mm (HxWxD) mean that it won’t take up too much space in your garden either.
