EHC Comet 12kW Electric Flow Electric boiler frequently asked questions

EHC Comet 12kW - combi, system or regular boiler?

EHC’s Comet 12kW is one you might consider if you’re looking for a electric Flow boiler for your house or flat.

Traditional boilers often have up to two tanks that either store heated water or water to be heated later. Boiler manufacturers introduced combi boilers in the 1970s to avoid the need for those big tanks. Combi boilers allow homeowners to benefit from the reliable central heating and hot water level they want but without having to give up so much space within their properties - remember that homes in the UK are among the smallest in the developed world.

Your taps and radiators get the hot water they need with a combi boiler. Combi boilers draw cold water direct from the mains which is then heated instantly on demand and distributed to your radiators and taps.

However, combi boilers cannot heat very large volumes of water, which is their main disadvantage. So, for example, when someone wants to take a shower while another person wants to use a hot water tap to do the dishes, water pressure and quantity to both points decreases.

Is a EHC Comet 12kW electric Flow a suitable choice for my house or flat?

You should make sure that the boiler you choose for your property is the right "size". And size doesn't mean its physical dimensions. Size means how much power it has - the "output".

A boiler's output level measures how much power it can use to provide you with the hot water you need for your radiators and taps. If a boiler has a high output rate, it can heat greater volumes of water.

If you choose a boiler with too low an output, you'll find that the water coming out of your taps and in your radiators won't be as hot as you want it to be. Choosing one whose output is too high means you'll pay more than you need to for the electric your boiler needs to work.

The EHC Comet 12kW electric Flow outputs at a maximum of 12 kW, so which types of property would this EHC Comet 12kW Electric Flow boiler be appropriate for?

An experienced boiler engineer would recommend that this EHC Comet 12kW Electric Flow boiler would be a suitable installation choice for smaller homes and apartments with up to 10 radiators and one bathroom.


What size is the EHC Comet 12kW boiler?

The EHC Comet 12kW occupies a space of 1,745 mm high by 630 mm wide and 580 mm deep.

Is the EHC Comet 12kW non-condensing or condensing?

The reason why the Government required all non-electric boilers to be "condensing" in 2005 was that they were much more energy-efficient. Rather than letting all exhaust gases escape into the atmosphere through the flue as older boilers did, condensing boilers use the warmth present in these gases to, for example, reheat water coming back from your radiators via a secondary heat exchanger. As electric boilers like the EHC Comet 12kW do not burn any fuel, they are more efficient by design, there are no gases to recycle, and so they are not covered by the 2005 law.

Is the EHC Comet 12kW electric Flow rated as environmentally friendly?

With more and more people concerned about climate change, how we heat our homes and the damage it does to the environment is increasingly being questioned by British homeowners.

Gas boilers are responsible for dangerous atmospheric levels of nitrogen dioxide emissions in Britain's biggest cities and, overall, 14% of the UK’s greenhouse gases are produced by our domestic central heating systems.

Let's take a closer look at whether installing a EHC Comet 12kW electric Flow would be a good choice for the environment.

By law, all boilers manufactured and supplied in the UK must have a minimum energy efficiency performance level of 92% (equivalent to a SEDBUK "A" grade). Until April 2018, the minimum performance level was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90%+ an "A" grade).

Energy efficiency tests record how much energy is wasted on non-core functions during normal operation.

The energy efficiency rating of the EHC Comet 12kW is 100% with a SEDBUK band rating of "D".

A penalty for being powered by electricity is reflected in the ERP ratings for this EHC Comet 12kW Electric Flow boiler.

The ERP, short for the Energy Related Products Directive, is a European directive aimed at encouraging manufacturers to create products that are environmentally friendlier at all stages, including during manufacturing, when the product is in active use, and right through to the point of final disposal.

The EHC Comet 12kW is rated "TBC" by ERP assessors.

On some models of electric boilers, ERP ratings are judged in a different and unfair way. Some electric boilers score very low because the electricity they draw for power is often generated by burning fossil fuels. This is despite the fact that electric boilers are nearly always more efficient than their gas and oil counterparts, at around the 98% to 99% mark, in most cases.

What is the length of the warranty on the EHC Comet 12kW?

The EHC Comet 12kW is covered by a parts and labour warranty of 2 years following installation.

EHC Comet 12kW Electric Flow Electric boiler frequently asked questions

What type of boiler is EHC’s Comet 12kW - system, regular or combi?

If you want a electric Flow boiler for your flat or house, the EHC Comet 12kW might be an option for you to consider.

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.

Is the EHC Comet 12kW electric Flow boiler suitable 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 Comet 12kW electric Flow boiler is 12 kW kilowatts. Which types of property would this be appropriate for?

A PlumbProud Gas Safe boiler installer would recommend that this EHC Comet 12kW Electric Flow boiler be installed in smaller homes and apartments with one bathroom and up to 10 radiators.


What size is a EHC Comet 12kW boiler?

The dimensions of the EHC Comet 12kW are 1,745 mm [H] x 630 mm [W] x 580 mm [D].

Comet 12kW – 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 12kW 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.

Does the EHC Comet 12kW electric Flow protect the environment?

As the British public has become more conscious of climate change, many homeowners consider the environment when choosing how to heat their homes.

With central heating being responsible for 14% of greenhouse gas emissions in the UK, your choice of boiler matters. Gas boilers are also responsible for the significant atmospheric volumes of dangerous nitrogen dioxide emissions in larger British cities.

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

All boilers manufactured and installed in the UK are required to have an energy efficiency rating of 92% or above (or a good “A” SEDBUK rating). Before April 2018, when the law changed, the minimum energy efficiency level permissible was 88% (86-90% is a SEDBUK "B" rating and 90%+ is an "A" rating).

A boiler's energy efficiency rating indicates the amount of energy used and wasted during normal operational performance.

Following its assessment, the EHC Comet 12kW was given an efficiency rating of 100% and a SEDBUK grading of "D".

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

The Energy Related Products Directive (ERP) is European legislation that applies to all products which use or consume energy during their lifespan, including during the manufacturing process and when they're in actual use, right through to the point of final disposal.

The aim is to encourage the manufacturers to create new products that are kinder to the environment and which create fewer harmful gas emissions.

The ERP rating for the EHC Comet 12kW is "TBC".

Many electric boilers are usually rated fairly low in ERP tests and unfairly so. Operational energy efficiency for electric boilers is actually around the 98-99% level in most cases. The reason they're marked down so severely is that the electricity used to power these boilers is generated by burning fossil fuels, which is considered carbon-intensive, and this is factored into their scores - not exactly a like-for-like comparison, in our opinion.

What warranty do I get if I purchase the EHC Comet 12kW boiler?

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