Ferroli LEB 12 Electric Flow Electric boiler frequently asked questions

Is the Ferroli LEB 12 a standard, combi or system boiler?

The Ferroli LEB 12 may be worth considering if you are looking for a electric Flow boiler for your house or flat.

Traditional boilers have one or more large tanks in which they store either heated water or water to be heated later. Manufacturers originally introduced combi boilers to the market in the 1970s to enable homeowners to save space - UK residential properties are among the smallest in the Western world.

Combi boilers don't need these tanks because they draw water directly from the mains and instantly heat it on demand thanks to the technology inside the boiler. Combi boilers then distribute this hot water to your home’s taps and radiators when needed.

The most significant disadvantage of combi boilers is that they are not ideal in larger homes where multiple people might want hot water at the same time – for example, if someone is having a shower while another wants to wash dishes in the kitchen. This is because combi boilers have a maximum volume of water that they can heat. When two people want hot water at the same time, the water temperature, pressure and volume delivered to both points drop.

Should I choose a Ferroli LEB 12 electric Flow boiler for my house or flat?

Selecting the right boiler for your property means selecting a boiler that is the right size. And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

The output of a boiler is measured in kilowatts. The output level determines the maximum power a boiler can use in heating the water needed for the baths, showers, taps and radiators in your home.

It's important to choose a boiler with an appropriate level of output for your property. Your boiler should be able to cope with periods of peak demand in your property and not just your average usage.

An output rate that is too low will result in an inadequate supply of hot water, while an output that is too high will mean the boiler will cost more to run than is necessary.

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

Most experienced boiler engineers would recommend this Ferroli LEB 12 Electric Flow boiler as a suitable option for smaller homes and apartments with no more than up to 10 radiators and one bathroom.


The size of the Ferroli LEB 12

The size of the Ferroli LEB 12 boiler is TBC mm tall, TBC mm wide, and TBC mm deep.

Is the Ferroli LEB 12 condensing or non-condensing?

Since 2005, all oil or gas boilers manufactured or installed in the UK must be more efficient condensing boilers. What this means is that the warmth present in exhaust gases created by the burning of oil or gas must be recycled via a secondary heat exchanger to, for example, heat water coming back from the radiators. As electric boilers like the Ferroli LEB 12 do not burn fuel, they are exempt from this law as they are more efficient and economical by design.

How does the Ferroli LEB 12 electric Flow boiler rate environmentally?

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

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 the environmental impact of installing a Ferroli LEB 12 electric Flow in your home be positive? Let's look at the numbers.

All boilers manufactured and supplied in the UK must achieve an energy efficiency rating of at least 92% (SEDBUK score of "A"). This is higher than the 88% that was the legal requirement prior to April 2018.

The energy efficiency rating is used to work out how much energy a boiler both uses and wastes when it's switched on and working normally - its standard functioning and operation.

The Ferroli LEB 12 is rated as 99.5% energy efficient, equivalent to a "D" SEDBUK rating.

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

The Energy Related Products Directive, also known as ERP, is European legislation intended to reduce energy consumption related to products, from the initial manufacturing process right through to their eventual final disposal.

The purpose of the directive is to encourage manufacturers to create new products that are kinder to the environment and which result in lower overall harmful gas emissions through a product's entire life cycle.

The ERP rating for the Ferroli LEB 12 is "TBC".

Why is it so low? It's because it uses electricity - this is considered carbon-intensive since fossil fuels are burned in its generation. Operationally, the energy efficiency of electric boilers is nearly always 98% or 99% so we feel this is a misleading comparison that unfairly reflects the actual performance of electric boilers.

What is the warranty period for the Ferroli LEB 12?

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

Ferroli LEB 12 Electric Flow Electric boiler frequently asked questions

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

If you’re looking for a electric Flow boiler for your house or flat, then the Ferroli LEB 12 is one you may wish to consider.

The UK has some of the smallest homes in the Western world, which is partly why combi boilers were introduced in the 1970s. Traditional boilers require one or more large storage tanks which they use to either heat water and keep it warm or store water intended for heating later. These tanks took up a lot of space in people's homes.

Combi boilers save space because they don't require these tanks to operate. Instead, combis draw water direct from your mains supply then instantly heat and distribute it on demand.

The biggest disadvantage in using combi boilers is that they have a maximum capacity volume for heating water. While this may not be an issue in a small household, it could be for a larger household where there is higher demand for hot water. When more than one person is using the water, it is distributed between the two points, reducing the pressure and temperature at each point.

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

You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".

Your boiler should be able to cope with peak hot water demand in your property and not just your average hot water usage. The output rate of a boiler is measured in kilowatts and tells you how much power a boiler can use to provide hot water to your taps, showers and radiators.

If the output of your boiler is too low, there will often be times when your water isn't as hot as you want. But if your boiler output is too high, it will be more costly to run (often unnecessarily).

The output of the Ferroli LEB 12 electric Flow boiler is 12 kW kilowatts. Which types of property would this 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 measures TBC mm in height and has a width of TBC mm and a depth of TBC mm.

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 does the Ferroli LEB 12 electric Flow boiler rate environmentally?

With environmental issues in the spotlight, more and more homeowners are becoming concerned about how they heat their homes and how much they're contributing towards combatting climate change.

In the UK, central heating systems account for 14% of greenhouse gas production. Gas boilers in particular are responsible for emissions of dangerous nitrogen dioxide in British cities.

Do the available figures suggest that installing the Ferroli LEB 12 electric Flow in your property would be an environmentally friendly choice?

In the UK, all boilers manufactured and supplied must have an energy efficiency rating of at least 92% or a SEDBUK "A" grade. Prior to April 2018, the minimum rating was 88% (88% and 89% are equivalent to a SEDBUK "B" rating and anything higher is rated as an "A" grade).

The Ferroli LEB 12 has been awarded an efficiency rating of 99.5% and a SEDBUK band rating 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.

If the Ferroli LEB 12 electric Flow boiler breaks down, am I covered?

On the Ferroli LEB 12, the manufacturer offers a parts and labour warranty of 2 years.
