EHC Comet 9kW Electric Flow Electric boiler frequently asked questions

Is this EHC Comet 9kW boiler a combi, system or regular boiler?

The EHC Comet 9kW is worthy of consideration if you're looking for a electric Flow boiler for your flat or house.

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 the EHC Comet 9kW electric Flow boiler the right choice for my house or apartment?

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

A boiler’s output is a measurement of the amount of power it can use to provide hot water to your taps and radiators. The higher its output rate, the more water it can heat.

If your new boiler’s output is too low, your hot water might not be as hot as you want it to be. If it's too high, you’ll be paying more for electric than you need to.

The output of the EHC Comet 9kW electric Flow boiler is 9 kW, so which types of property would this be appropriate for?

To most experienced Gas Safe engineers, the EHC Comet 9kW electric Flow Comet would be most suitable for smaller homes and apartments with up to 10 radiators and one bathroom.


The size of the EHC Comet 9kW in millimetres

The EHC Comet 9kW's dimensions are 1,745 mm [H] x 630 mm [W] x 580 mm [D].

EHC Comet 9kW – condensing or non-condensing?

Gas and oil boilers burn fuel to heat the water you need for your home - electric boilers like the EHC Comet 9kW do not. Condensing non-electric boilers create exhaust gases which they then recycle to heat the water coming back through your pipes to your radiator, among other tasks, for greater efficiency. Because electric boilers do not create these gases when operating, they do not need the secondary heat exchanger found in condensing boilers.

Is the EHC Comet 9kW electric Flow environmentally friendly?

Price and performance are two important issues when choosing a boiler but now, for many people in the UK, so is the environmental impact of how we heat our homes and its effect on climate change.

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.

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

Every boiler manufactured and supplied in the UK must have an energy efficiency rating of 92% (SEDBUK “A” rating). These minimums were made law in April 2018 - before that, the minimum energy efficiency rating was 88% (88%/89% = "B" SEDBUK grade, 90%+ = "A" SEDBUK grade).

The EHC Comet 9kW was awarded an efficiency rating of 100% and a band rating of "D".

Energy efficiency ratings for boilers describe the amount of energy they use and waste when switched on and working.

The boiler is however penalised in its ERP ratings for using electricity for power.

The ERP (or Energy Related Products Directive) is European legislation which applies to all products that consume energy throughout their lifetime.

Its purpose is to encourage manufacturers to offer products that are kinder to the environment by reducing harmful gas emissions at all stages, from production and end use right through to disposal.

Electricity generation currently involves burning fossil fuels, which is carbon-intensive. This is factored into the ERP scores of many electric boilers, although virtually every electric boiler has an energy efficiency in operation of near 100%.

The ERP rating for the EHC Comet 9kW is "TBC".

Is there a warranty on the EHC Comet 9kW electric Flow boiler if it breaks down?

The parts and labour warranty on the EHC Comet 9kW lasts for 2 years.

EHC Comet 9kW Electric Flow Electric boiler frequently asked questions

EHC Comet 9kW - a regular boiler, combi boiler or system boiler?

You might want to consider the EHC Comet 9kW for your house or flat if you are looking for a electric Flow boiler.

Combination or combi boilers are highly efficient and save a lot of space in your home. Combi boilers heat water directly from the mains when you turn on a tap and, as a result, you don’t need a hot water storage cylinder or a cold water tank in the roof space.

These boilers are, therefore, suitable for smaller homes and especially those without a loft. They are also cost-effective as the water is heated instantly and distributed on demand rather than being stored. Combi boilers are the most popular type of boilers in the UK and replacing an older boiler with a new combi boiler will reduce your electric bills significantly.

However, there are downsides to this type of boiler. If you take a shower while someone else is using a tap, less water will reach each point of usage at lower rates of pressure and temperatures as combi boilers can only heat a certain volume of water at any given time.

Should I install a EHC Comet 9kW electric Flow boiler in my house or apartment?

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

The output level of a boiler tells you how much power it has to heat the water coming from your taps and warming up your radiators. The higher the output level, the greater the volume of water it can heat up.

If the output (measured in kilowatts) is too high, you'll pay higher electric bills and your water will be piping hot. Too low and the water coming out of your taps and being fed into your radiators will often be lukewarm.

The EHC Comet 9kW electric Flow outputs at a maximum of 9 kW, so which types of property would this EHC Comet 9kW Electric Flow boiler be appropriate for?

A Gas Safe engineer would recommend that the EHC Comet 9kW electric Flow boiler is a suitable choice for smaller homes and apartments with up to 10 radiators and one bathroom.


What dimensions does a EHC Comet 9kW have?

The EHC Comet 9kW is 1,745 mm tall, 630 mm wide, and 580 mm deep in size.

Is the EHC Comet 9kW condensing or non-condensing?

The law passed in 2005 requiring all boilers installed in the UK to be "condensing" boilers does not apply to electric boilers. This is because, unlike non-electric boilers, electric boilers do not burn either gas or oil to operate and create no hot exhaust gases that can be recycled. Electric boilers like the EHC Comet 9kW are more efficient and economical by design.

Is the EHC Comet 9kW electric Flow environmentally friendly?

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.

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 choosing the EHC Comet 9kW electric Flow be an environmentally-friendly choice? If so, let's look at its performance figures.

Boilers manufactured and installed in the UK are assigned energy efficiency ratings following testing to an agreed set of standards. These scores indicate how much energy the boiler uses and how much goes to waste when it's in operation.

By law, boilers must achieve a SEDBUK rating of "A" subject to achieving a minimum of 92% energy efficiency. Prior to April 2018, the minimum was 88% (88% and 89% on the SEDBUK are "B" graded and 90% and above are graded "A").

The EHC Comet 9kW was awarded an efficiency rating of 100% with a SEDBUK band rating of "D".

The ERP ratings of this EHC Comet 9kW 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 Comet 9kW has been graded "TBC" 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.

How long is the warranty period on the EHC Comet 9kW electric Flow boiler?

The EHC Comet 9kW boiler comes with a parts and labour warranty of 2 years.
