Ferroli LEB 12 Electric Flow Electric boiler frequently asked questions

Ferroli LEB 12 - a combi boiler, system boiler or regular boiler?

The Ferroli LEB 12 is a electric electric Flow boiler.

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 the Ferroli LEB 12 electric Flow boiler a suitable option for my house or flat?

Whether this Ferroli LEB 12 Electric Flow boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions - it means how powerful it is.

A boiler’s output is a measurement of the amount of power it can use to provide hot water to your taps and radiators. The higher its output rate, the more water it can heat.

If your new boiler’s output is too low, your hot water might not be as hot as you want it to be. If it's too high, you’ll be paying more for electric than you need to.

The output of the Ferroli LEB 12 electric Flow boiler is 12 kW, so which types of property would this be appropriate for?

An experienced PlumbProud boiler engineer would likely recommend this Ferroli LEB 12 Electric Flow boiler as suitable for smaller homes and apartments with up to 10 radiators and one bathroom.


Where will the Ferroli LEB 12 fit in my house?

The Ferroli LEB 12 measures TBC mm in height by TBC mm in width by TBC mm in depth.

Is this Ferroli boiler non-condensing or condensing?

The law passed in 2005 requiring all boilers installed in the UK to be "condensing" boilers does not apply to electric boilers. This is because, unlike non-electric boilers, electric boilers do not burn either gas or oil to operate and create no hot exhaust gases that can be recycled. Electric boilers like the Ferroli LEB 12 are more efficient and economical by design.

How energy efficient is the Ferroli LEB 12 electric Flow boiler?

Many homeowners are now worried about climate change and the damage they do to the environment from heating their homes has become a subject of increasing concern.

In Britain's bigger cities, gas boilers, in particular, are responsible for dangerous levels of nitrogen dioxide emissions. Overall, 14% of all of the UK’s greenhouse gas production comes from heating our homes.

Would installing a Ferroli LEB 12 electric Flow boiler in your home be a green choice? Let's look at the numbers.

All boilers manufactured and supplied in the UK are assigned two energy efficiency ratings. By law, they must achieve a SEDBUK "A" rating subject to a minimum efficiency level of 92%. Prior to 2018, the minimum was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90% and above an "A" grade).

The rating awarded to the Ferroli LEB 12 is 99.5% with a SEDBUK rating of "D".

ERP assessors are however not keen that the boiler is powered by electricity.

The Energy Related Products Directive (ERP) was introduced in 2015 and applies to all products that consume energy throughout their lifetime, including during the manufacturing process and at the point of final disposal.

The purpose of the ERP is to ensure that companies create products that are kinder to the environment by reducing both the energy they use and the harmful emissions they produce.

An ERP rating of "TBC" has been awarded to the Ferroli LEB 12.

This is very low, but why? In reality, nearly every electric boiler on the market has an actual energy efficiency in operation of near 100%. However, some electric boilers have low ERP scores because the electricity generation process currently involves burning fossil fuels, which is considered carbon-intensive, and this is factored into the score - unfairly, in our opinion.

Am I covered if my Ferroli LEB 12 electric Flow boiler breaks down?

The Ferroli LEB 12 boiler comes with a parts and labour warranty lasting 2 years.

Ferroli LEB 12 Electric Flow Electric boiler frequently asked questions

Is this Ferroli LEB 12 boiler a combi, system or regular boiler?

Ferroli’s LEB 12 is one you might consider if you’re looking for a electric Flow boiler for your house or flat.

Combi boilers have much to recommend them - not least the fact that they save a lot of space. Combination (or combi) boilers were introduced by manufacturers in the 1970s to provide practical central heating and hot water distribution to smaller properties - remember that UK houses and flats tend to be among the smallest in the developed world.

Traditional boilers require one or more storage tanks to keep hot water warm and to store water for heating later. In contrast, combi boilers draw water directly from the mains supply and heat it instantly, removing the need for a storage tank. The heated water is then distributed to your taps and radiators on demand.

While combi boilers are suitable choices for many properties, especially those without a loft, there is also a disadvantage in using them. Water is heated instantly and the volume of water that can be heated at any one time is limited. This can result in less water being sent to taps and showers if more than one is being used simultaneously. In these instances, the water pressure to both points will drop.

Is a Ferroli LEB 12 electric Flow boiler suitable for my house or apartment?

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 LEB 12 Electric Flow boiler gets its power from electric 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 electric bills.

The Ferroli LEB 12 electric Flow boiler has an output level of 12 kW, so which types of property would it be appropriate for?

A Gas Safe boiler installer would recommend that this Ferroli LEB 12 Electric Flow boiler would provide adequate heating and hot water for smaller homes and apartments with up to up to 10 radiators and one bathroom.


Ferroli LEB 12 dimensions

The Ferroli LEB 12 is TBC mm tall, TBC mm wide, and TBC mm deep in size.

Ferroli LEB 12 – non-condensing or condensing?

There is no legal requirement in the UK for electric boilers to be condensing as there is for gas and oil boilers. This is because electric boilers like the Ferroli LEB 12 do not burn fuel during their operation nor do they create exhaust gases that condensing boilers then extract the warmth from, for example, to heat water coming back from the radiators in a home. Electric boilers are more efficient by design than non-electric boilers.

Is the Ferroli LEB 12 electric Flow an environmentally friendly boiler?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of climate change.

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

Will choosing to install a Ferroli LEB 12 electric Flow in your home help the environment? Let's review the figures.

All boilers manufactured and supplied in the UK from April 2018 must achieve a SEDBUK “A” rating and an energy efficiency rating of 92% or above. Before that, the minimum was 88% - 88% and 89% energy efficiency was given a “B” rating and 90%+ an "A".

A boiler's energy efficiency rating describes how much energy it uses and wastes during its standard operation.

The energy efficiency of the Ferroli LEB 12 was rated at 99.5% with a SEDBUK grading of "D".

The ERP ratings of this Ferroli LEB 12 Electric Flow boiler are however marked down because it's powered by electricity.

The ERP (Energy Related Products Directive) applies to all products that consume energy at any time in their lifetime, from manufacture to disposal and at all points in between.

The intention of this European legislation is to encourage manufacturers to offer end users products that are better for the environment through the creation of fewer harmful gas emissions at all points of a product's life cycle.

The Ferroli LEB 12 has an ERP rating of "TBC".

In reality, however, nearly every electric boiler on the market in Britain has an operating energy efficiency near 100%. Electric boiler ERP scores appear low because the electricity generation process currently involves burning fossil fuels, which is considered carbon-intensive, and this is factored into the score. Here at PlumbProud, we don't believe this is comparing like with like.

Does a Ferroli LEB 12 electric Flow boiler come with a warranty period?

The Ferroli LEB 12 boiler comes with a 2 year warranty for parts and labour.
