The Worcester Bosch Greenstar Utility Regular is a high output oil-fired boiler that is designed for large homes and small commercial properties.
Need an energy efficient oil boiler for your large home or small commercial premises? The Worcester Bosch Greenstar Utility Regular could be the boiler for you. This floor-standing model is A-rated for efficiency and can be purchased with a huge output of either 50kW or 70kW to meet your high heating and hot water demands. It has achieved Which? Best Buy status, boasts a superb reliability score and has even been given the thumbs up by consumers and engineers.
How Much Does this Boiler Cost?
Greenstar Utility Regular prices vary according to the heat output, usually from £2,100 to £2,270 including VAT. The amount you’ll need to spend will depend on whether you need the 50kW or 70kW unit. Don’t forget, boiler prices between suppliers can vary, so you may be able to save some cash by shopping around and comparing quotes. You also need to remember to factor in the cost of installation which, again, can vary quite a bit depending on how much work is required to fit the boiler.
How will I know if this Boiler is Suitable for My Home?
The Worcester Bosch Greenstar Utility Regular is an oil-fired regular boiler and will require a separate hot water cylinder, as well as tanks in your roof space. It’s a good option for homes with more than one bathroom and properties that receive lower water pressure. Because this model is available in such high heat outputs, it’s only recommended for large homes and small commercial building where a lot of hot water tends to be used at the same time.
Although both the 50kW and 70kW are suitable for large dwellings and light commercial sites, it’s still important that you select the correct size of boiler for your property. It’s unlikely that you’ll be able to get the size (kW output) right without seeking advice from an OFTEC registered engineer, so be sure to consult a professional before purchasing this model.
Is it a High Efficiency Boiler?
Yes, it is a high efficiency oil-fired condensing boiler with an excellent efficient rating of 93%. By being A-rated, the Worcester Bosch Greenstar Utility Regular will not only provide efficient heating and hot water but also help to lower your fuel bills and reduce your carbon footprint. What’s more, the boiler is compatible with Greenstore cylinders and Greenskies solar panels to offer additional energy and cost savings.
Does this Boiler have a Good Range of Controls and Features?
It doesn’t have the largest selection of user controls we’ve ever seen but you can adjust the central heating temperature. All of the controls are concealed at the front of the boiler to ensure it fits in with the other appliances installed in your utility room or commercial boiler area. This is a bit of bonus if you have young children because it means they won’t be able to play with any buttons or dials that are hidden behind the front panel. If you want complete control over your heating and hot water, it might be worth purchasing the optional Bosch EasyControl. It’s basically a smart thermostat that allows you to control everything from a smartphone or tablet. The EasyControl also lets you monitor your energy use.
How long is the Warranty on this Boiler?
Like all Worcester Bosch oil-fired boilers, the Greenstar Utility Regular comes with a 2-year parts and labour warranty as standard. Worcester Bosch does sometimes extend its oil boiler warranties, so don’t forget to check the website to see if you can take advantage of any offers or promotions.
