Is the Ferroli LEB 9 a combi, system or regular boiler?

The Ferroli LEB 9 boiler is an option you may wish to consider if you're looking for a electric Flow boiler for your house or flat.

In the past, most boilers needed one or more storage tanks to operate - one to store warm water and the other for storing water to be heated later. But storage tanks are problematic in properties where space is at a premium and particularly where there is no loft. Many properties in the UK are small and so manufacturers introduced combi boilers in the 1970s to eliminate the need for tanks.

With a combi boiler, the hot water for your radiators and taps is delivered on demand. The boiler instantly heats water it draws directly from the mains internally. It then distributes the heated water around your home at mains pressure as you need it.

It is important to bear in mind that, while combi boilers have many benefits, they can only heat a certain volume of water at any given time. This means that, if you run a shower at the same time as someone else is doing the washing up in the kitchen, the volume of water passing to each point will drop, causing a fall in pressure.

Is a Ferroli LEB 9 electric Flow boiler suitable for my house or flat?

Whether this Ferroli LEB 9 Electric Flow boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions, however - it means how powerful it is.

Measured in kilowatts, a boiler's output level is an indication of the amount of power it has available to it to heat the water coming from your taps and for warming your radiators. The greater the output level, the more water it can heat.

If you choose a boiler whose output level is too low, you'll often find that the water is not as hot as you want it to be. If you choose a boiler whose level is too high, you'll be paying higher electric bills than you need to for years to come.

The output of the Ferroli LEB 9 electric Flow is 9 kW, so which types of property is this Ferroli LEB 9 Electric Flow boiler appropriate for?

A PlumbProud Gas Safe boiler installer would recommend that this Ferroli LEB 9 Electric Flow boiler be installed in smaller homes and apartments with one bathroom and up to 10 radiators.

What are the dimensions of the Ferroli LEB 9 boiler?

The Ferroli LEB 9 is 740 mm tall, 440 mm wide, and 265 mm deep.

Is the Ferroli LEB 9 condensing or non-condensing?

For just over 15 years, all gas and oil boilers installed in the UK must by law be "condensing" boilers. This means that all non-electric boilers must use the warmth present in exhaust gases to, among other tasks, heat the cold water coming back from radiators via a secondary heat exchanger. Because electric boilers like the Ferroli LEB 9 do not burn fuel or create exhaust gases, they do not need to be modified and are therefore exempt from the legislation passed in 2005.

Is the Ferroli LEB 9 electric Flow environmentally friendly?

With more and more of us concerned about environmental issues and climate change, how we heat our homes has become an important issue to many homeowners.

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

If you decide to install a Ferroli LEB 9 electric Flow in your home, will you be helping the environment with your choice? Let’s have a look at the figures.

By law, all boilers manufactured and supplied in the UK achieve a SEDBUK rating of "A" and work at a minimum of 92% energy efficiency. Before April 2018, a minimum of 88% energy efficiency needed to be achieved (88/89% = SEDBUK "B" and 90% = SEDBUK "A").

Following official testing, the Ferroli LEB 9 was given an efficiency rating of 99.5% with a SEDBUK rating of "D".

Energy efficiency is a measure of how much energy is used and how much is wasted when a boiler is operating.

The ERP ratings of this Ferroli LEB 9 Electric Flow boiler are however marked down because it is powered by electricity.

All products that consume energy throughout their lifespan must comply with the Energy Related Products (ERP) Directive.

Companies are legally obliged to reduce harmful gas emissions at all stages of a product's life cycle, from initial manufacturing right through to final disposal as well as when the product is in use.

As fossil fuels generate the power used by electric boilers, some receive low ERP scores because electricity generation is carbon-intensive. This is unfair because the actual operational energy efficiency of most electric boilers is either 98% or 99% - a level no oil or gas boiler has yet reached.

The ERP rating for the Ferroli LEB 9 is "TBC".

Does the Ferroli LEB 9 electric Flow boiler come with a warranty?

The Ferroli LEB 9 boiler comes with a parts and labour warranty of 2 years.
