EHC Fusion Comet 6KW - a regular, combi or system boiler?

Looking for a electric system boiler for your house or flat? If you are, the EHC Fusion Comet 6KW boiler may be worth considering.

A system boiler needs a hot water cylinder to work but it does not require a cold water tank, unlike with heat only boilers. This makes system boilers suitable for properties that lack loft space (or have no loft at all) or where a loft conversion is planned. The cylinder stores hot water for use throughout the day and water can be distributed to more than one tap or shower simultaneously without a loss of pressure or temperature (something combi boilers really struggle with).

System boilers are generally found in larger homes or properties housing large families. System boilers are easier to install than heat only boilers because their major components, including the circulation pump, are built-in and, of course, no cold water tank is needed.

With a system boiler, you use the control panel to set times for when you want the heating and hot water to be available but, unlike combi boilers, they cannot deliver hot water instantly. If you don't set your timer, you will have to wait for the water to heat up.

Would the EHC Fusion Comet 6KW system be a suitable choice of boiler 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 Fusion Comet 6KW system outputs at a maximum of 6 kW, so which types of property would this EHC Fusion Comet 6KW System boiler be appropriate for?

Most boiler engineers would recommend that a boiler with this output level would be most suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

What dimensions does a EHC Fusion Comet 6KW have?

The EHC Fusion Comet 6KW stands at 710 mm tall, 418 mm wide and 252 mm deep.

Is the EHC Fusion Comet 6KW condensing or non-condensing?

In 2005, the Government passed a law meaning that all gas and oil boilers had to be "condensing" boilers. What this means is that they all now must feature a secondary heat exchanger that recycles the gas and oil exhaust emissions to heat water coming back from the radiators, among other tasks. Electric boilers like the EHC Fusion Comet 6KW do not create exhaust gases and therefore do not need this modification.

How environmentally friendly is the EHC Fusion Comet 6KW system?

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.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

Will installing a EHC Fusion Comet 6KW system in your home be a positive contribution to the environment? The figures below will tell you more.

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 Fusion Comet 6KW 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's poor ERP rating however reflects the fact that it runs on electricity.

In 2015, the EU introduced the Energy Related Products Directive (ERP), the aim of which was to ensure that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

The legislation aims to conserve energy at all life cycle stages, from initial production to the product's actual use by the customer, through to the point of disposal.

This EHC Fusion Comet 6KW System boiler's ERP rating is "D".

How is this so given that electric boilers are nearly always more efficient than their gas and oil counterparts, with an actual operational efficiency rating around the 98% to 99% mark, in most cases? Some electric boilers receive very low ERP scores because the electricity they draw for power is often generated by burning fossil fuels. In our opinion, this is unfair on electric boilers.

What is the length of the warranty on the EHC Fusion Comet 6KW?

You receive a parts and labour warranty of 2 years with the EHC Fusion Comet 6KW boiler.
