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

Looking for a electric system boiler for your flat or house? Then the EHC Fusion Comet 9KW may be an option you should consider.

As with a heat only boiler, a system boiler requires the installation of a hot water cylinder but they do not need a cold water tank to work. This makes them suitable choices for homeowners planning a loft conversion or for properties without a loft or very limited attic space.

The primary heating and hot water system components are built in to system boilers and you can use the control panel to set the times that you wish your heating and hot water to be available. Hot water is stored in the cylinder for use throughout the day, but if you don't set your timer, heat and hot water will not be available instantly.

A system boiler can supply multiple taps and showers simultaneously and is suitable for both large families and properties with more than one bathroom - combi boilers struggle to do this.

Is the EHC Fusion Comet 9KW system boiler suitable for my house or apartment?

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

Measured in kilowatts, a boiler's output level is an indication of the amount of power it has available to it to heat the water coming from your taps and for warming your radiators. The greater the output level, the more water it can heat.

If you choose a boiler whose output level is too low, you'll often find that the water is not as hot as you want it to be. If you choose a boiler whose level is too high, you'll be paying higher electric bills than you need to for years to come.

The output of the EHC Fusion Comet 9KW system is 9 kW, so which types of property is this EHC Fusion Comet 9KW System boiler appropriate for?

Most Gas Safe engineers would suggest that the most suitable type of property for installing a EHC Fusion Comet 9KW system boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.

The size of the EHC Fusion Comet 9KW

The size of the EHC Fusion Comet 9KW boiler is 710 mm tall, 418 mm wide, and 252 mm deep.

Fusion Comet 9KW – non-condensing or condensing?

For just over 15 years, all gas and oil boilers installed in the UK must by law be "condensing" boilers. This means that all non-electric boilers must use the warmth present in exhaust gases to, among other tasks, heat the cold water coming back from radiators via a secondary heat exchanger. Because electric boilers like the EHC Fusion Comet 9KW do not burn fuel or create exhaust gases, they do not need to be modified and are therefore exempt from the legislation passed in 2005.

Is the system EHC Fusion Comet 9KW boiler energy efficient?

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about 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.

Will you be helping the environment if you decide to install a EHC Fusion Comet 9KW system in your home? Let’s look at the figures.

The energy efficiency rating for boilers describes the amount of energy they use and waste during operation and there are two different ways to measure it.

All boilers manufactured and supplied in the UK must have a SEDBUK rating of “A” subject to a minimum energy efficiency score of 92% or above. Before April 2018, the minimum energy efficiency score was 88% (88/89% = "A" SEDBUK rating, 90%+ = "B" SEDBUK rating).

The EHC Fusion Comet 9KW scored an efficiency rating of 100% and a SEDBUK band rating 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 Fusion Comet 9KW is "D".

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.

Does the EHC Fusion Comet 9KW system boiler come with a warranty?

You receive a parts and labour warranty of 2 years with the EHC Fusion Comet 9KW boiler.
