Elnur Mattira 12 System - a combi boiler, system boiler or regular boiler?

Suitable for a house or a flat, the Elnur Mattira 12 System electric Flow boiler is worth considering if you want a electric Flow boiler.

Combi boilers were introduced by manufacturers in the 1970s to offer British homeowners a way to cheaply and reliably heat their homes and have hot water without taking up too much space. Previously, most boilers had one or more storage tanks, which either heated water and kept it warm or held water to be heated later.

With combi boilers, there is no need to find space for large tanks around your home as the hot water needed for your radiators and taps is available on demand. Combi boilers do this by drawing water from your mains supply, heating it instantly whenever you need it and then distributing it to where it's needed in the home.

The major disadvantage to combi boilers is that they have a maximum capacity for heating water. In a larger household, water pressure, volume and temperature will drop if two or more people are trying to use hot water at the same time.

Would the Elnur Mattira 12 System electric Flow be a suitable 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.

Boiler output is measured in kilowatts and tells you how much power a boiler can use to heat the water your taps, showers and radiators need. The higher the output, the more power it has.

When choosing a boiler, you should choose one that can cope with the peak demand for hot water in your home and not just your typical usage.

If its output is too low, sometimes your hot water will not be hot enough, but if your boiler's output is too high for your needs, your electric bills will go up and not down.

The output of the Elnur Mattira 12 System electric Flow is 12 kW, so which types of property would this Elnur Mattira 12 System Electric Flow boiler be an appropriate choice for?

A PlumbProud heating engineer would recommend that this Elnur Mattira 12 System Electric Flow boiler is suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

Making space for the Elnur Mattira 12 System

The Elnur Mattira 12 System's dimensions are TBC mm [H] x TBC mm [W] x TBC mm [D].

Is the Elnur Mattira 12 System non-condensing or condensing?

Previously, gas and oil boilers were pretty inefficient and, in 2005, a law was passed requiring that all new gas and oil boilers must be "condensing". Condensing boilers contain a secondary heat exchanger that uses the exhaust gases created by burning gas and oil to, for example, reheat water coming back from the radiators. As electric boilers like the Elnur Mattira 12 System do not burn fuel in the home, they do not need this modification.

Is the Elnur Mattira 12 System electric Flow environmentally friendly?

How we heat our homes has become a pressing issue of concern for many homeowners worried about climate change and the environmental impact of their personal choices.

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

Would installing a Elnur Mattira 12 System electric Flow boiler in your home help combat climate change? What do the figures suggest?

Boilers manufactured and supplied 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 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 12 System has been assigned an efficiency rating of 100% with a SEDBUK rating of "D".

The boiler is however penalised in its ERP ratings for using electricity for power.

The ERP (Energy Related Products Directive) is European legislation that aims to reduce the use of energy at all points during a product's life, from the point of manufacture to when it's in active use right through to final disposal.

The aim of the regulation is to encourage manufacturers to create products that are more environmentally friendly and which reduce the gas emissions associated with those products.

The ERP grading for the Elnur Mattira 12 System is "TBC".

This is very low, especially given the advances made in electric boiler technology over the last 5 years. However, the comparison is, in our opinion, unfair because the actual operational energy efficiency of most electric boilers is either 98% or 99% - a level no oil or gas boiler has yet reached. The reason for some boilers' poor ERP scores is that the electricity they need to operate is generated by the burning of fossil fuels, which the assessors consider to be carbon-intensive.

Am I covered if the Elnur Mattira 12 System electric Flow boiler breaks down?

You receive a parts and labour warranty of 2 years with the Elnur Mattira 12 System boiler.
