What type of boiler is the EHC Slim Jim 10KW?

You may wish to consider installing the EHC Slim Jim 10KW if you are looking for a electric Flow boiler for your house or flat.

Traditional boilers need one or more large tanks to work - one to heat and keep water warm for immediate use and the other to store water intended for heating later. Finding space for these large tanks is difficult in British residential property - remember that our houses and flats are among the smallest in the world. This is the problem that combi boilers were designed to solve when they were introduced in the 1970s.

Combi boilers don't need a tank - instead, they instantly heat water drawn from the mains using technology inside the boiler. This hot water is then distributed immediately to your taps or radiators on demand.

The biggest disadvantage to combi boilers is that they have a maximum capacity for heating water, meaning that they work best when only one point within a household wants hot water. For example, if someone is taking a shower and another person uses a hot water tap at the same time, the water pressure, volume and temperature to both points drops.

Should I install a EHC Slim Jim 10KW electric Flow boiler in 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".

Output measures in kilowatts how much power a boiler can use when heating water for your radiators or taps. The higher the output rate, the more water it can heat.

If the output rate is too low, your hot water might often be only lukewarm, and if it is too high, you will be paying more for your electric than you need to.

The EHC Slim Jim 10KW electric Flow boiler has an output of 10 kW, so which types of property would it be most appropriate for?

An experienced heating engineer would say that this EHC Slim Jim 10KW Electric Flow boiler's level of output makes it a suitable installation for smaller homes and apartments with up to 10 radiators and one bathroom.

What size is a EHC Slim Jim 10KW boiler?

The EHC Slim Jim 10KW measures 912 mm in height and has a width of 203 mm and a depth of 172 mm.

Slim Jim 10KW – non-condensing or condensing?

In order to protect the environment, the government required all new boilers in the UK to be "condensing" from 2005, although this law does not apply to electric boilers. This is because, unlike gas and oil boilers, electric boilers like the EHC Slim Jim 10KW do not produce hot exhaust gases that condensing boilers then recycle to reheat water coming back from the radiators in a home.

Is the EHC Slim Jim 10KW electric Flow boiler environmentally friendly?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.

Approximately 14% of the UK's greenhouse gas production is caused by our central heating systems. The gas boilers in larger urban areas of Britain are mainly responsible for emissions of toxic nitrogen dioxide.

Would choosing a EHC Slim Jim 10KW electric Flow help in the fight against climate change? What do the performance statistics 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 10KW has been awarded 100% for its energy efficiency, equivalent to a SEDBUK "D" rating.

But because it's powered by electricity, it's penalised in its ERP ratings.

The Energy Related Products Directive's intention is to encourage all manufacturers to reduce harmful gas emissions connected to the products they make, from the manufacturing stage to final disposal, including when they are in active use.

The EHC Slim Jim 10KW’s ERP rate is "D".

Why is it so low despite the fact that, operationally, the energy efficiency of electric boilers is nearly always 98% or 99%? It's because the electricity these boilers draw for power is often generated by burning fossil fuels, which ERP assessors class as carbon-intensive. In our opinion, this is not comparing like for like.

Am I covered if my EHC Slim Jim 10KW electric Flow boiler breaks down?

On the EHC Slim Jim 10KW, the manufacturer offers a parts and labour warranty of 2 years.
