BUYING GUIDE- Worcester Bosch Greenstar Danesmoor Utility Boilers

Given below is a detailed guide on Worcester Bosch Greenstar Danesmoor Utility Boilers:

Does this Boiler have a Good Range of Controls and Features?

This boiler doesn’t have the largest selection of user controls but the ones it does have are concealed behind a panel to ensure the boiler won’t look out of place when installing next to other kitchen or utility room appliances. When it comes to features, the Greenstar Danesmoor Utility Regular has an efficient primary heat exchanger and an upgraded secondary heat exchanger to enable the boiler to exceed ErP efficiency requirements. It also has an inspection hatch for easy access and a one-piece baffle to ensure annual services can be carried out quickly. Furthermore, this model is Bosch EasyControl compatible to enable you to monitor your energy use and manage your heating and hot water from a smartphone or tablet.

Is it a High Efficiency Boiler?

It sure is. The Greenstar Danesmoor Utility Regular is an A-rated floor-standing oil boiler with a seasonal space heating energy efficiency rating of 90%. If you decide to swap an old oil-fired regular boiler for this model, you’ll not only cut your fuel bills but also dramatically reduce your carbon footprint. But that’s not all. This boiler is compatible with Greenskies solar panels and Greenstore cylinders which, when used together, can provide around 60% of your home’s hot water and save you some serious cash.

How long is the Warranty on this Boiler?

All Worcester Bosch oil-fired boilers come with a 2-year parts and labour warranty as standard, which is what you’ll get with the Greenstar Danesmoor Utility Regular. In the past, Worcester Bosch has offered extended 5-year promotional warranties on oil-fired boilers, so be sure to check the brand’s website.

How will I know if this Boiler is Suitable for My Home?

Because it’s a regular boiler (also called a conventional, traditional or heat only boiler), the Worcester Bosch Greenstar Danesmoor Utility Regular is most suited to homes where a separate hot water storage cylinder and cold-water tanks in the loft are already installed. Regular boilers are also ideal for properties with multiple bathrooms and high hot water demands. As this particular model comes in three heat outputs of 18kW, 25kW and 32kW, it’s suitable for small, medium and large homes.

The highest output option is designed for properties with greater demands, whereas the lowest is intended for homes with smaller needs. But how can you know for sure? It’s pretty much impossible to select the right oil boiler output for your house without consulting an OFTEC registered engineer. A qualified engineer will need to assess your property and requirements in order to recommend the perfect boiler type and output for your household.
