Worcester Bosch Greenstar Danesmoor External 18/25 System Boiler

Designed and manufactured by Worcester Bosch, the Greenstar Danesmoor External 18/25 is a condensing oil system boiler with an output rating of 25 kW. It has the same features as the internal model but can be installed in an outdoor area.

How efficient is the Greenstar Danesmoor External 18/25?
This is a highly efficient boiler that could help to lower your energy bills which is shown by the efficiency rating of 90% and ErP A-rating.

Is a 25 kW output rating suitable for my home?

A system boiler with an output rating of 25 kW is perfectly suited to a home with 1 bathroom and around 15 radiators.

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

There are 3 models in the Greenstar Danesmoor External range all with different outputs and this 25 kW model sits right in the middle. So, if you have a lower heating demand then the 18 kW is available while higher demand can be met by the 32 kW boiler.
Is a system boiler suitable for my home?

System boilers are the perfect fit for homes with a higher demand for hot water as they’re part of a heating system that also includes a hot water cylinder. This also means that it’s essential to have room in your home for a cylinder in addition to the boiler.

How long is the warranty?

Worcester Bosch have made their Greenstar Danesmoor External boilers available with a 2 year warranty as standard but this can be extended to 5 years by meeting certain terms and conditions.

What are the key features of the Danesmoor External 18/25?

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

As an external boiler, protection from the elements is essential and a green powder coated cabinet does just that. Plus, as it’s green, it will camouflage the unit with its outdoor surroundings.

How big is the Danesmoor External 18/25?

The Greenstar Danesmoor External 18/25 has been designed for installation in an outdoor area. Plus, its dimensions of 950 x 565 x 780mm (HxWxD) mean that it won’t take up too much space in your garden either.
