Prices vary according to the heat output and typically start at £1,800 and rise to around £2,500 including VAT. This means the higher the output, the more expensive the boiler will be. It often pays to shop around because some suppliers offer competitive deals or are happy to beat quotes that you have obtained elsewhere.
How will I know if this Boiler is Suitable for My Home?
The Worcester Bosch Greenstar Danesmoor External System is an oil-fired system boiler. System boilers need to be installed with a separate cylinder for storing hot water and tend to be best for homes with more than one bathroom. As this system model is an oil boiler, it’s also a sensible option for those who live off the gas grid. If you have a large house and greater demands for heating and hot water, you’re probably going to need the 25kW or 32kW unit. Smaller households with lower demands should steer towards the 18kW version. You must keep in mind that this is just a rough guide, though.
If you want to know whether or not the Greenstar Danesmoor External System is the perfect solution for your home, you’ll need to get some advice from an OFTEC registered engineer. A qualified heating professional will also be able to tell you the correct heat output for your property.
Is it a High Efficiency Boiler?
Yes, it is. The Greenstar Danesmoor External System has an ‘A’ ErP efficiency rating, meaning it should help to save you money on your fuel bills. This is especially true if you currently have an old boiler model installed and decide to replace it with this efficient condensing model. Not forgetting that the boiler can be used with Worcester Bosch’s range of Greenskies solar panels and Greenstore cylinders, both of which provide additional energy and cost savings.

As for the Greenstar Danesmoor External System, it comes with inbuilt frost protection, a one-piece baffle for quick servicing and flexi-flue and plume management kits.
