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

Suitable for a house or a flat, the EHC Comet 12kW electric Flow boiler is worth considering if you want 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.

Would the EHC Comet 12kW electric Flow be a suitable boiler for my house or flat?

Whether this EHC Comet 12kW Electric Flow boiler is right for your property depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output rating indicates how much energy a boiler can use in providing you with hot water and heat when you need it from your radiators and taps. The greater the output, the more water it can heat.

It's better to take advice on this from a registered installer because, if your boiler output is too low, your water and radiators might not get as hot as you would like them to be. However, if the output level is too high, you'll end up paying more on your electric bills than you need to.

Which types of property would this EHC Comet 12kW Electric Flow boiler be appropriate for given its output of 12 kW?

An experienced Gas Safe engineer would be likely to recommend that this EHC Comet 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.

What is the size of the EHC Comet 12kW?

The EHC Comet 12kW measures 1,745 mm high and 630 mm wide by a depth of 580 mm.

Is the EHC Comet 12kW non-condensing or 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 Comet 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 choosing the EHC Comet 12kW electric Flow boiler 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.

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

Will you be helping the environment if you decide to install a EHC Comet 12kW electric Flow in your home? Let’s look at the figures.

In the UK, all boilers manufactured and supplied must have an energy efficiency rating of at least 92% or a SEDBUK "A" grade. Prior to April 2018, the minimum rating was 88% (88% and 89% are equivalent to a SEDBUK "B" rating and anything higher is rated as an "A" grade).

The EHC Comet 12kW has been awarded an efficiency rating of 100% and a SEDBUK band rating of "D".

The ERP ratings of this EHC Comet 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 Comet 12kW 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.

Does a EHC Comet 12kW electric Flow boiler come with a warranty period?

A parts and labour warranty of 2 years is included with the EHC EHC Comet 12kW boiler.
