Ferroli Bluehelix Tech S 45H Boiler

The Ferroli Bluehelix Tech S 45H is a heat-only gas boiler ideal for larger homes with a higher demand for hot water.

Ferroli’s Bluehelix Tech S 45H is a wall-hung gas condensing boiler suitable for properties that already have a heat-only boiler system installed. The boiler is A-rated for efficiency, meaning it should help to lower your carbon footprint and save you some money on your energy bills. It has compact dimensions and can fit in small spaces, but it does require tanks in the loft and a separate hot water cylinder. 

How Much Does this Boiler Cost?

The Bluehelix Tech S 45H will set you back anything around £1,600, including VAT. However, you also need to pay labour and installation costs, which vary depending on who you choose to install your heat-only boiler. You must always hire a Gas Safe registered engineer to carry out the installation, and we suggest you get a quote from local and national installers so that you can find the best price. 

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

Heat-only boilers require tanks in the loft and a hot water storage cylinder, so you need to have these components already in place or enough space to store them. The Ferroli Bluehelix Tech S 45H is a powerful boiler with a 45kW output and suitable for large homes with high hot water demands, multiple bathrooms and more than 20 radiators. 

You must identify the correct heat-only boiler size for your property so that you can enjoy a comfortable home without wasting money on running costs. Selecting a new boiler is a big decision, so be sure to consult a qualified heating engineer who can give you professional advice and help you pick the correct boiler size. 

Is it a High Efficiency Boiler?

Yes. The Bluehelix Tech S 45H is a highly efficient heat-only boiler with a 98% space heating energy efficiency rating. It even has an ‘Eco’ function in domestic hot water for greater energy savings when you’re not using hot water.  

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

Ferroli’s Bluehelix Tech S 45H is easy to use and comes with a digital control panel and a large multi-function backlit graphic display. It has a total premix burner in stainless steel and a low consumption modulating heat pump. The boiler can be combined with a modulating remote timer to give you greater control over your heating system and an optional external probe that monitors the outdoor temperatures and helps the boiler work more efficiently. 

How long is the Warranty on this Boiler?

The Ferroli Bluehelix Tech S 45H heat-only boiler comes with a 2-year warranty as standard.
