What type of boiler is EHC’s Slim Jim 12KW - system, regular or combi?

Looking for a electric electric Flow boiler for your house or flat? If you are, the EHC Slim Jim 12KW boiler may be worth considering.

Combi boilers are excellent for providing hot water and heat for your radiators just when you need it. When you have a combi boiler installed in your home, you just turn on the tap and the hot water for your bath, shower, washing dishes and other activities is there when you need it. It also provides the heat you need to keep your radiators warm.

A combi boiler heats the cold water passing through it, which it draws from the mains. This newly heated water can then be distributed to whichever hot tap or radiator needs it.

In the past, boilers needed at least one storage tank to hold water that was either already heated or would be heated later. Sometimes, you'd have to wait for hot water because there was none left. In addition, storage tanks took up a lot of space and most UK homes are pretty small.

The main disadvantage to combi boilers is that they can only heat a certain amount of water at any one time, meaning the pressure, volume and temperature of water will decrease if more than one tap is on at the same time or if both the shower and washing machine are on together.

Would the EHC Slim Jim 12KW electric Flow be a suitable 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 - its "output".

The output rate tells you how much energy your boiler has to use to provide you and your family with hot water and central heating. A higher output rate means that it can heat greater volumes of water.

Please be aware, though - if you choose a boiler whose output is too low, the water in your radiators and coming from your taps may not be warm enough. Conversely, if you choose a boiler with too high an output, you'll pay more for electric than is necessary.

The EHC Slim Jim 12KW electric Flow boiler has an output level of 12 kW, so which types of property would it be appropriate for?

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 measurements of the EHC Slim Jim 12KW are 912 mm by 203 mm by 172 mm.

EHC Slim Jim 12KW – condensing or non-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 EHC Slim Jim 12KW 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 EHC Slim Jim 12KW electric Flow an environmentally friendly 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 EHC Slim Jim 12KW electric Flow boiler in your home help combat climate change? What do the figures suggest?

All boilers manufactured in the UK or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to 2018, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The EHC Slim Jim 12KW has been awarded 100% for its energy efficiency, equivalent to a SEDBUK "D" rating.

However, the ERP rating for this EHC Slim Jim 12KW Electric Flow boiler is marked down because it runs on electricity.

Manufacturers who offer more environmentally friendly products are rewarded by the ERP (or Energy Related Products Directive).

Operationally, the energy efficiency of electric boilers is nearly always 98% or 99% - however, because they use electricity, which is considered carbon-intensive energy, some are (in our opinion) unfairly scored down in their ERP ratings for this.

In the case of the EHC Slim Jim 12KW, the ERP rating is "D".

What warranty do I get if I purchase the EHC Slim Jim 12KW boiler?

The EHC Slim Jim 12KW boiler is covered by a parts and labour warranty of 2 years.
