What type of boiler is Elnur’s Mattira 15 Combi - system, regular or combi?

The Elnur Mattira 15 Combi boiler could be suitable for your house or flat if you are looking for a new electric Flow boiler.

Combi boilers have much to recommend them - not least the fact that they save a lot of space. Combination (or combi) boilers were introduced by manufacturers in the 1970s to provide practical central heating and hot water distribution to smaller properties - remember that UK houses and flats tend to be among the smallest in the developed world.

Traditional boilers require one or more storage tanks to keep hot water warm and to store water for heating later. In contrast, combi boilers draw water directly from the mains supply and heat it instantly, removing the need for a storage tank. The heated water is then distributed to your taps and radiators on demand.

While combi boilers are suitable choices for many properties, especially those without a loft, there is also a disadvantage in using them. Water is heated instantly and the volume of water that can be heated at any one time is limited. This can result in less water being sent to taps and showers if more than one is being used simultaneously. In these instances, the water pressure to both points will drop.

Would the Elnur Mattira 15 Combi electric Flow be a suitable choice of boiler for my house or flat?

To determine that, we need to consider the size of the boiler. Size doesn't mean how big it is - it means how big its "output" is.

The output rate of a boiler tells you how much power it has available to it for heating the water that comes out of your taps and warms your radiators. A higher output rate means that your boiler has more power at its disposal.

You need to make sure you select a boiler with the right output rate. That's because, if your output rate is too high, then your boiler will have more power than it needs but it will cost too much to run. If the output rate is too low, your water may often not be hot enough.

The Elnur Mattira 15 Combi electric Flow's output is 15 kW, so which types of property would this Elnur Mattira 15 Combi Electric Flow boiler be appropriate for?

A Gas Safe boiler installer would recommend that this Elnur Mattira 15 Combi Electric Flow boiler would provide adequate heating and hot water for smaller homes and apartments with up to up to 10 radiators and one bathroom.

Elnur Mattira 15 Combi size

The Elnur Mattira 15 Combi measures TBC mm high and TBC mm wide by a depth of TBC mm.

Is the Elnur Mattira 15 Combi non-condensing or condensing?

Electric boilers like the Elnur Mattira 15 Combi do not produce exhaust gases, unlike gas and oil boilers, meaning they do not need to be adapted to be "condensing". For a gas or oil boiler to be condensing, it must have a secondary heat exchanger that recycles the warmth present in exhaust gases to reheat water coming back from the radiators.

Is the Elnur Mattira 15 Combi electric Flow boiler an environmentally friendly choice?

The effects of climate change on the environment are leading many homeowners to question the damage they might be doing by the way they 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.

Will installing a Elnur Mattira 15 Combi electric Flow in your home be a positive contribution to the environment? The figures below will tell you more.

Gas and oil boilers manufactured in the UK must be tested and, by law, achieve an energy efficiency rating of 92% or above, equivalent to a SEDBUK "A" grade. Most boilers achieve an "A" rating meaning that they are at least 88% efficient.

The energy efficiency of a boiler indicates the amount of energy it uses (and wastes) during operation.

The Elnur Mattira 15 Combi has been assigned an efficiency rating of 36.4% with a SEDBUK rating of "D".

This is very low but why? In reality, nearly every electric boiler on the market has an energy efficiency in operation of near 100%. However, electric boiler energy efficiency appears low on some models because the electricity generation process currently involves burning fossil fuels, which is considered carbon-intensive, and this is factored into the score - unfairly, in our opinion.

How long am I covered by the warranty for if the Elnur Mattira 15 Combi breaks down?

The Elnur Mattira 15 Combi boiler offers a parts and labour warranty of 2 years.
