Ferroli Bluehelix 34C Combi Gas boiler frequently asked questions

What kind of boiler is the Ferroli Bluehelix 34C - standard, combi or system?

The Ferroli Bluehelix 34C is a combi boiler you may wish to consider if you want this particular type of boiler for your house or flat.

In older British homes, traditional boilers required you to find room for one or more storage tanks. One tank would keep hot water warm and the other stored cold water for later heating. Manufacturers introduced combi boilers to the UK in the 1970s so that homeowners could get the warmth and hot water they needed without having to sacrifice too much valuable space – remember that residential property in this country is among the smallest in the Western world.

Combi boilers deliver hot water to your radiators and taps using water they draw directly from the mains supply. As mains water travels through a combi boiler, the technology within it heats the cold water instantly and on demand. The hot water is then distributed throughout your house.

Combi boilers have one drawback, however: they can only heat a certain amount of water within a given time. For example, if someone uses the shower and another person uses the hot water tap at the same time, water pressure drops because water reaches each point differently.

Is the Ferroli Bluehelix 34C combi boiler the right choice for my house or apartment?

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

Your boiler's output indicates the maximum amount of power available to it to heat the water you need to warm your radiators or when you want hot water from your taps. A higher output rate means that your boiler is capable of heating greater volumes of water.

If a boiler's output rate is too low, you'll often find that the water is not as hot as you want it to be. Too high, however, and you'll end up paying more for your gas than you should be.

The Ferroli Bluehelix 34C combi boiler has an output rate of 30 kW, so which types of property would this be suitable for?

Most experienced Gas Safe boiler installers would suggest that the Ferroli Bluehelix 34C combi boiler would be a suitable choice for installation in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

Please remember too that all combi boilers draw water from the mains - they have no storage tanks. Combis heat the water from the mains on demand and then send it to wherever it's needed in the house, like a radiator, a bathroom or a kitchen.

The speed at which it can do this is called the "flow rate", which is measured in litres per minute. If you have a lot of radiators and bathrooms in your home and multiple people are regularly trying to use the hot water at one time, such as in the morning or evening, you'll need a combi with a high flow rate. This Ferroli Bluehelix 34C 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. If the flow rate of the local water supply is 11l/m, you shouldn't purchase a boiler with a flow rate of 17l/m because it will never be able to use that extra capacity.

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.


How large is the Ferroli Bluehelix 34C?

The Ferroli Bluehelix 34C is 700 mm in height, 420 mm in width and 320 mm in depth.

Is the Ferroli Bluehelix 34C a condensing or non-condensing boiler?

We always recommend to clients that they select the very latest condensing boiler for their home.

Condensing boilers like the Ferroli Bluehelix 34C are more efficient with the gas they use in operation, meaning that you'll benefit from lower fuel bills. Condensing boilers are also better for the environment.

They achieve their efficiency by capturing and recycling the heat still present in the water vapour condensation and flue exhaust gases created when a boiler burns gas to get the energy it needs. It then reuses that recycled heat to perform a number of tasks, including heating the colder water that comes back to your boiler via the radiator.

Is the Ferroli Bluehelix 34C combi environmentally friendly?

The effects of climate change on the environment are leading many homeowners to question the damage they might be doing by the way they heat their homes.

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.

Let's take a closer look at whether installing a Ferroli Bluehelix 34C combi would be a good choice for the environment.

All new British boilers must perform to a legal minimum energy efficiency of 92% (a low to good SEDBUK "A" rating). Prior to April 2018, the target was 88% (86-90% = SEDBUK "B" and 90%+ = SEDBUK "A").

Efficiency ratings are intended to let consumers know how much energy a boiler uses in its day-to-day activities and how much energy goes to waste.

The Ferroli Bluehelix 34C was awarded an efficiency rating of 94%, equivalent to a SEDBUK grade of "A".

The Energy Related Products Directive grades products according to the energy they consume and the harmful gas emissions they create, from manufacturing right through to final disposal, including how they're used by customers between these two points.

The Ferroli Bluehelix 34C is rated "A" for heat and "A" for water.

What warranty do I get if I purchase the Ferroli Bluehelix 34C boiler?

The Ferroli Bluehelix 34C boiler comes with a 10 year warranty for parts and labour.

Ferroli Bluehelix 34C Combi Gas boiler frequently asked questions

What type of boiler is the Ferroli Bluehelix 34C - regular, system or combi?

Suitable for a house or a flat, the Ferroli Bluehelix 34C combi boiler is worth considering if you want a combi boiler.

Traditional boilers have one or two tanks - one holds hot water to keep it warm and the other water for later heating. Because UK residential property is among some of the smallest in the world, manufacturers introduced combi boilers and the heat pumps that go in them in the 1970s to reduce the amount of space boilers needed to take up.

The hot water needed for your radiators and taps is available on demand when you have a combi boiler. Combi boilers use technology located within the boiler to heat cold water, which it draws from the mains, and to distribute hot water where it's needed around your home.

A combi boiler, however, has the disadvantage of a maximum capacity for the amount of water it can heat. The result is that if someone uses the shower while another uses a hot water tap simultaneously, the amount of water reaching each point falls, causing water pressure to drop.

Is the Ferroli Bluehelix 34C combi boiler suitable for my house or apartment?

You should make sure that the boiler you install in your property is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

Your boiler has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your gas bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Ferroli Bluehelix 34C combi's output at 30 kW, which types of property would this Ferroli Bluehelix 34C Combi boiler be most appropriate for?

An experienced Gas Safe boiler installer would recommend that the Ferroli Bluehelix 34C combi boiler would be an ideal installation option for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

With all combi boilers, the "flow rate" (measured in litres per minute) is as important a consideration as output rate when choosing which model to go for. This Ferroli Bluehelix 34C Combi boiler's flow rate is TBCl/m.

Like all combi boilers, the Ferroli Bluehelix 34C draws water from the mains. It instantly heats that water and then distributes it to the parts of your home which need it - taps, radiators, bathrooms, and so on.

However, the water in the mains pipe that feeds your boilers has its own flow rate - normally between 10 and 12l/m. So if you choose a combi with a flow rate of 14l/m but local water pressure is equivalent to 11l/m, your boiler will actually operate at 11l/m - below its capacity.

In addition, if different family members want hot water at the same time (like for regular morning and evening showers) and your boiler has to provide hot water to your radiators at the same time, a combi boiler may not be suitable.

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 is the size of the Ferroli Bluehelix 34C?

The Ferroli Bluehelix 34C is 700 mm tall, 420 mm wide, and 320 mm deep in size.

Bluehelix 34C – non-condensing or condensing?

The Ferroli Bluehelix 34C is a condensing gas boiler - this is the type of boiler we recommend to most clients because they're better for the environment and they will save money on annual fuel bills.

A condensing boiler captures and recycles the warmth still present in both the flue exhaust gases and water vapour condensation created when gas is burned to provide your boiler with power.

This means it needs less gas to operate and it uses this extra energy to perform a number of tasks, including heating the colder water that comes back to the boiler from the radiators in your home.

How does the Ferroli Bluehelix 34C combi boiler rate environmentally?

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

Dangerous levels of nitrogen dioxide emissions in larger UK cities are caused by gas boilers in domestic properties, and 14% of the UK’s greenhouse gas production is as a result of central heating.

Would the environmental impact of installing a Ferroli Bluehelix 34C combi in your home be positive? Let's look at the numbers.

An energy efficiency rating of 92% or above is a legal requirement for all boilers manufactured and installed in the UK today. 92% is equivalent to a low-to-middle "A" grade on the "Seasonal Efficiency of Domestic Boilers" (SEDBUK) scale.

Energy efficiency measures how much energy a boiler uses and wastes in the course of its normal operation. The lower the waste, the lower your gas bills.

The Ferroli Bluehelix 34C was awarded an efficiency rating of "94%", equivalent to a "A" rating on the SEDBUK system.

The Energy Related Products Directive (ERP) came into force in 2015. This legislation was introduced to encourage manufacturers to create more energy-efficient products and it covers all products that consume energy during their lifetimes, including energy used during production and at the point of disposal.

ERP ratings of "A" for heat and "A" for water were assigned when testing the Ferroli Bluehelix 34C.

How long is the warranty period on the Ferroli Bluehelix 34C combi boiler?

The Ferroli Bluehelix 34C boiler has a warranty covering parts and labour costs for up to 10 years after installation.
