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

The EHC Fusion Comet 6KW boiler is a system boiler you may wish to consider when looking for a new boiler for your house or flat.

System boilers share many similarities with more traditional heat only boilers, like the need to program the times you want them to provide you with heat and hot water - just use the control panel to do this.

Where they differ from regular boilers is that they do not require a separate cold-water tank - everything is done within the hot water cylinder, which contains built-in circulating pumps. This makes them easier to install as there is one less component to fit and makes them more suitable for properties with no loft space, smaller lofts or for homeowners who are considering converting their loft.

As long as you have programmed your system boiler in advance, you will have the hot water you need ready for whenever you want to use it. Once the water is heated, it will remain available, warm, inside the tank until it’s all used up. It will then draw more water from the mains to start heating so that it can provide heat and hot water for the times you've told the system boiler you need it.

Is a EHC Fusion Comet 6KW system boiler appropriate for my house or apartment?

Selecting the right boiler for your home means choosing a boiler that is the right size. And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

Your boiler’s output is a measurement of the power it has available to it to heat the water you need for your radiators or for when you turn on a tap, bath or shower. A higher output rate means it has more power and can heat more water.

It's important to choose an output that matches the demand for water in your home because if your boiler has too low an output, you'll often find only lukewarm water comes out of your taps or heats your radiators. If it’s too high, you’ll be paying more for your electric than you need to.

The EHC Fusion Comet 6KW system has an output of 6 kW, so which types of property would this EHC Fusion Comet 6KW System boiler be appropriate for?

Most experienced heating engineers would likely recommend that, at this level of output, this EHC Fusion Comet 6KW System boiler would be a suitable choice 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 a non-condensing or condensing boiler?

Because electric boilers operate differently from non-electric boilers, they are not covered by the law which requires all boilers to be "condensing". That's because they don't actually burn fuel in your home. Condensing gas and oil boilers recycle the warmth present in exhaust gases created through the burning of fuel to reheat water coming back from radiators.

Is the EHC Fusion Comet 6KW system boiler an environmentally friendly choice?

Many homeowners are now worried about climate change and the damage they do to the environment from heating their homes has become a subject of increasing concern.

Central heating produces 14% of all greenhouse gas emissions in the UK. Gas boilers in the larger cities emit dangerous levels of nitrogen dioxide.

Will choosing a EHC Fusion Comet 6KW system boiler for your home be positive for the environment? Let's examine the figures.

An energy efficiency rating of 92% or above is a legal requirement for all boilers manufactured and installed in the UK today. 92% is equivalent to a low-to-middle "A" grade on the "Seasonal Efficiency of Domestic Boilers" (SEDBUK) scale.

Energy efficiency measures how much energy a boiler uses and wastes in the course of its normal operation. The lower the waste, the lower your electric bills.

The EHC Fusion Comet 6KW was awarded an efficiency rating of "100%", equivalent to a "D" rating on the SEDBUK system.

The boiler's poor ERP rating reflects the fact that it runs on electricity.

The Energy Related Products (ERP) directive is Europe-wide legislation designed to reduce harmful gas emissions at all points of a product's life cycle – from the production process to its actual end use right through to final disposal.

The EHC Fusion Comet 6KW has been awarded a grading of "D" by assessors.

Some electric boilers receive low energy efficiency scores since the electricity used to power them is generated by fossil fuels – considered carbon-intensive – and this is factored into the final rating. This is despite the fact that the actual operating energy efficiency of electric boilers is either 98% or 99% – better than even the most efficient gas or oil boiler.

How many years does the warranty period cover on a EHC Fusion Comet 6KW boiler?

The EHC Fusion Comet 6KW is supplied with a parts and labour warranty of 2 years.
