EHC Slim Jim 12KW Electric Flow Electric boiler frequently asked questions

Is the EHC Slim Jim 12KW a system, regular or combi boiler?

The EHC Slim Jim 12KW may be worth considering if you are looking for a electric Flow 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.

Should I choose a EHC Slim Jim 12KW electric Flow boiler for my house or flat?

It's best to choose a boiler whose size or "output" is right for your home.

The more hot water and heat you want, the higher the output level of your boiler should be. Output is measured in kilowatts and it describes the maximum level of power your boiler has to heat water.

If your output level is too low, your boiler will not have the power it needs to get your water as hot as you want it, particularly when there's a lot of demand for it. Choose a boiler whose output level is too high and you'll have all the hot water you need but will be paying too much for it through higher electric bills.

Which types of property would this EHC Slim Jim 12KW Electric Flow boiler be appropriate for given its output of 12 kW?

An experienced Gas Safe engineer would be likely to recommend that this EHC Slim Jim 12KW Electric Flow boiler is capable of providing heating and hot water to up to 10 radiators and one bathroom and would therefore be most suitable for smaller homes and apartments.


Making space for the EHC Slim Jim 12KW

The EHC Slim Jim 12KW is 912 mm high by 203 mm wide by 172 mm deep.

Is the EHC Slim Jim 12KW a condensing or non-condensing boiler?

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 EHC Slim Jim 12KW do not burn fuel, they are exempt from this law as they are more efficient and economical by design.

Is the EHC Slim Jim 12KW electric Flow good for the environment?

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.

The power we need for our central heating systems accounts for around 14% of the UK’s greenhouse gas production. There are often dangerous levels of ambient nitrogen dioxide gases in the atmospheres of British cities because of our use of gas boilers.

Is the EHC Slim Jim 12KW electric Flow boiler an environmentally friendly choice for your home? Here’s what the figures say.

Under current UK law, all boilers must achieve a minimum energy efficiency level of 92% (a low to good SEDBUK "A" rating). The minimum level was raised from its previous 88% in April 2018.

Energy efficiency scores are intended to inform consumers of the amount of energy used and wasted when a boiler is in normal operation.

The EHC Slim Jim 12KW was awarded an efficiency rating of 100% with a SEDBUK band rating of "D".

The boiler is however penalised in its ERP rating for being powered by electricity.

The Energy Related Products (ERP) Directive is a European directive which applies to all products that consume energy over their lifetime.

It encourages companies to create products that are environmentally friendlier at all life cycle stages, including initial manufacturing and end use right through to final disposal, with the aim of reducing harmful gas emissions.

The ERP rating for the EHC Slim Jim 12KW is "D".

How can it be so low? The use of fossil fuels in generating the electricity that powers the boiler is considered carbon-intensive, and this is factored into the ERP scores of electric boilers. This is, in our opinion, unfair because the actual operating energy efficiency of electric boilers is 98% or 99% - better than even the most efficient gas or oil boiler.

If the EHC Slim Jim 12KW electric Flow boiler breaks down, am I covered?

The EHC Slim Jim 12KW boiler is provided with a parts and labour warranty lasting 2 years.

EHC Slim Jim 12KW Electric Flow Electric boiler frequently asked questions

EHC Slim Jim 12KW - a system boiler, regular boiler or combi boiler?

The EHC Slim Jim 12KW is a electric electric Flow boiler.

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 EHC Slim Jim 12KW electric Flow boiler right for my house or apartment?

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 EHC Slim Jim 12KW 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 EHC Slim Jim 12KW 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.


The size of the EHC Slim Jim 12KW in millimetres

The EHC Slim Jim 12KW is 912 mm [H] by 203 mm [W] by 172 mm [D] in size.

Is the EHC Slim Jim 12KW a condensing or non-condensing boiler?

When a boiler is a "condensing" boiler, it uses the warmth present in the exhaust gases created by the burning of gas or oil to reheat cold water coming back from the radiators via a secondary heat exchange. Because electric boilers like the EHC Slim Jim 12KW don't actually burn fuel in the home, they don't require a flue or a secondary heat exchanger - they're naturally more efficient by design.

How environmentally friendly is the EHC Slim Jim 12KW electric Flow?

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.

Central heating produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

Do the available figures suggest that installing the EHC Slim Jim 12KW electric Flow in your property would be an environmentally friendly choice?

By law, the minimum level of energy efficiency for all boilers manufactured in and supplied to the UK is 92%, equivalent to a good SEDBUK “A” rating. Prior to April 2018, the minimum was 88% - boilers whose energy efficiency levels were 88% or 89% were given a "B" rating on the SEDBUK scale and those at 90% or higher were given an "A".

The energy efficiency rating awarded to each boiler indicates the amount of energy that is wasted when in operation.

Following testing, the EHC Slim Jim 12KW was given an energy efficiency rating of 100% and a SEDBUK grading of "D".

The ERP ratings of this EHC Slim Jim 12KW Electric Flow boiler are however marked down because it's powered by electricity.

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 EHC Slim Jim 12KW has been graded "D" by ERP assessors.

Some electric boilers receive lower ERP scores because of the carbon emissions created by the burning of fossil fuels to generate the electricity they use for power. This is unfair because the actual operational energy efficiency of most electric boilers is either 98% or 99% - a level that no oil or gas boiler has yet reached.

If the EHC Slim Jim 12KW breaks down, will I be covered by the warranty?

The parts and labour warranty on the EHC Slim Jim 12KW covers all repair-related costs for 2 years while the heat exchange warranty covers you for [Heat Exchange Warranty] years.
