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.
