Ferroli Bluehelix 28C Combi Gas boiler frequently asked questions

Is this Ferroli Bluehelix 28C boiler a combi, system or regular boiler?

Looking for a gas combi boiler for your house or flat? If you are, the Ferroli Bluehelix 28C boiler may be worth considering.

One of the reasons the combi boiler was introduced to Britain in the 1970s was because residential properties are among the smallest in the world. More traditional boilers require one or more large tanks to be stored around the home to function.

A combi boiler is a self-contained unit that draws water from the mains then heats and distributes it instantly and on demand - no tanks are needed.

They are the most popular type of boilers in the UK and offer only one major disadvantage - there is a maximum volume of water that can be heated at any one time. If that limit is exceeded by, for example, two people using a hot water tap at the same time, there will be a drop in water pressure, temperature and volume to both taps.

Is a Ferroli Bluehelix 28C combi boiler suitable for my house or flat?

To determine that, we need to consider the size of the boiler. Size doesn't mean how big the boiler is - it means how big its "output" is.

This Ferroli Bluehelix 28C Combi boiler gets its power from gas and the power it's capable of producing is measured in kilowatts - the output rate is actually a kilowatt rate. The higher the output rate, the more kilowatts a boiler can use when heating water.

If you choose a boiler whose output rate is too low, it may not have enough power to make your water as hot as you would like. If you choose a boiler whose output rate is too high, you won't have to put up with lukewarm water but you will face higher gas bills.

The Ferroli Bluehelix 28C combi boiler has an output level of 24 kW, so which types of property would it be appropriate for?

An experienced PlumbProud boiler engineer would likely recommend this Ferroli Bluehelix 28C Combi boiler as suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

With combi boilers like the Ferroli Bluehelix 28C, you need to take the flow rate into account as well as the output rate.

Combi boilers draw water from the mains and then instantly heat that water and send it to wherever in your home it's needed. Flow rates, measured in litres per minute, are subject to the mains water pressure in your area. So, for example, if the local mains water pressure is 11 litres per minute and the flow rate of your boiler is 14 litres per minute, the boiler will not be able to process more than 11 litres per minute. The flow rate of this Ferroli Bluehelix 28C Combi boiler is TBCl/m.

If you live in a home with lots of radiators or bathrooms where many people want to use hot water at the same time, a combi boiler may not be able to cope. For reference, a power shower uses about 10 litres of water per minute. If two people want showers at the same time or one person wants a shower and the other hot water from a tap in the kitchen, your boiler may not have a large enough flow rate even if the local mains water pressure is high.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


What are the dimensions of the Ferroli Bluehelix 28C boiler?

The Ferroli Bluehelix 28C is 700 mm high by 420 mm wide by 250 mm deep.

Ferroli Bluehelix 28C – condensing or non-condensing?

The Ferroli Bluehelix 28C is a condensing gas boiler - where possible, we always recommend to clients that they choose one of the very latest condensing boilers to take advantage of this technology, which improves year after year.

Condensing boilers are more energy-efficient as they capture and recycle the heat contained in flue exhaust gases and water vapour condensation. They then use this heat to perform tasks like warming up colder water returning to the boiler from the radiators.

By choosing a condensing boiler, you'll help the environment as well as save money on your gas bills.

Is the Ferroli Bluehelix 28C combi environmentally friendly?

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about climate change.

In the UK, central heating is responsible for 14% of greenhouse gas production. Domestic gas boilers emit large quantities of nitrogen dioxide in British cities.

Do the available figures suggest that installing the Ferroli Bluehelix 28C combi in your property would be an environmentally friendly choice?

The energy efficiency rating of the Ferroli Bluehelix 28C is 94% with a SEDBUK band rating of "A".

Energy efficiency tests record how much energy is wasted on non-core functions during an operation.

By law, all boilers manufactured and supplied in the UK must have a minimum energy efficiency performance level of 92% (equivalent to a SEDBUK "A" grade). Up to April 2018, the minimum performance level was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90%+ an "A" grade).

In 2015, new legislation was introduced by the EU to encourage manufacturers to develop more energy-efficient products that emit fewer harmful gases throughout their lifetime.

The Energy Related Products Directive (ERP) applies to all products that consume energy, including during the manufacturing process, at the point of final disposal, and all points in between.

The ERP rating of the Ferroli Bluehelix 28C is "A" for heat and "A" for hot water.

How many years does the warranty period cover on a Ferroli Bluehelix 28C boiler?

On the Ferroli Bluehelix 28C, the manufacturer offers a parts and labour warranty of 10 years.

Ferroli Bluehelix 28C Combi Gas boiler frequently asked questions

Is the Ferroli Bluehelix 28C boiler a combi, regular or a system boiler?

The Ferroli Bluehelix 28C is an option you may wish to consider if you’re looking for a combi boiler for your house or flat.

In many properties, combi boilers are more suitable than traditional types of boiler. Combi boilers heat water instantly on demand, which they draw directly from the mains supply, removing the need for storage tanks that can take up valuable space in your home.

A combi boiler is often the right choice for a smaller property, particularly if your home doesn't have a useable loft. As water is heated and delivered immediately rather than being kept warm for hours in an immersion tank, combi boilers reduce gas usage, thereby minimising your heating costs.

The main disadvantage of combi boilers is that they can only heat a certain amount of water at any one time. This means that, if two people are using different taps or showers within your home at the same time, the flow of heated water to each will be reduced, as will the water pressure and temperature.

Would the Ferroli Bluehelix 28C combi be a suitable boiler for my house or flat?

Whether this Ferroli Bluehelix 28C Combi boiler is right for where you live depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output of a boiler is measured in kilowatts and indicates how much energy it can use to heat the water needed for your radiators, taps and showers. The greater the output, the more water it can heat.

A boiler whose output is too high will give you hot water and warm radiators but also higher gas bills, whereas a boiler whose output is too low will result in cheaper gas bills but the water might not always be as hot as you want it to be.

The output of the Ferroli Bluehelix 28C combi is 24 kW, so which types of property would this model be appropriate for?

Most experienced boiler engineers would recommend this Ferroli Bluehelix 28C Combi boiler as a suitable option for smaller homes and apartments with no more than up to 10 radiators and one bathroom.

In addition to the output rate, you should consider a boiler's "flow rate" (measured in litres per minute) when choosing a combi boiler.

If you have a lot of radiators and bathrooms in your home and members of your household want to use hot water at the same time (like morning or evening showers and baths), you'll need a boiler with a high flow rate. This Ferroli Bluehelix 28C Combi boiler's flow rate is TBCl/m.

However, it's not that simple. Combis can only draw water from the mains at the speed it's delivered. Homes with higher than average demand for hot water, and particularly those in low mains pressure areas, may find that a combi boiler is not the right answer for them.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead to better serve you and your family.


How large is a Ferroli Bluehelix 28C boiler?

The Ferroli Bluehelix 28C measures 700 mm tall, 420 mm wide, and 250 mm deep.

Is the Ferroli Bluehelix 28C condensing or non-condensing?

The Ferroli Bluehelix 28C is a condensing gas boiler - we strongly recommend that you choose one of the latest condensing models if possible.

With a condensing boiler, you save money on your gas bills because your boiler captures and recycles the heat present in the flue exhaust gases and water vapour condensation for re-use, meaning they operate far more economically and efficiently.

Is the Ferroli Bluehelix 28C combi a good choice for the environment?

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on climate change.

Nitrogen dioxide emissions in Britain's largest cities are at dangerous levels and this has been caused by gas boilers. In fact, 14% of the UK’s greenhouse gases are produced by central heating.

If you decide to install a Ferroli Bluehelix 28C combi in your home, will you be helping the environment with your choice? Let’s have a look at the figures.

Boilers manufactured after April 2018 in the UK must achieve an "A" on the SEDBUK grading system as well as score a minimum of 92% on a separate energy efficiency test. Prior to that, the minimum was 88% - boilers rated at 88% and 89% were given a “B” rating (90% and higher were given an "A").

An energy efficiency rating describes how much energy the boiler uses and how much it wastes when in use.

The Ferroli Bluehelix 28C was awarded an efficiency rating of 94% with a SEDBUK grading of "A".

Energy-efficient boilers help the environment as they require less fuel and emit fewer harmful gases. In 2015, the EU introduced the Energy Related Products Directive (ERP), the aim of which was to ensure that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

The legislation aims to conserve energy at all life cycle stages from initial production to actual use by the customer, through to the point of disposal.

The Ferroli Bluehelix 28C has been given an ERP rating of "A" for heat and "A" for water.

Am I covered if my Ferroli Bluehelix 28C combi boiler breaks down?

The Ferroli Bluehelix 28C boiler is covered by a parts and labour warranty of 10 years.
