Is the Vaillant EcoFIT Pure 618 a standard, combi or system boiler?

The Vaillant EcoFIT Pure 618 is a system boiler you may wish to consider if you want this type of boiler for your house or flat.

System boilers, like regular boilers, require a hot water cylinder (usually placed in a landing or airing cupboard) to work but they don’t require a separate cold water tank. This makes installation quicker and easier and, for homeowners with little loft space or who are considering a loft conversion, they're a more suitable choice.

System boilers don't need separate water tanks because they contain built-in circulating pumps that perform the same task. Just like heat only boilers, they require you to program in the times when you want heating and hot water to be available - they don't offer instant hot water like combi boilers. The cylinders keep whatever water they contain warm, although, if there is no hot water in the tank, you will have to wait up to an hour before hot water will come through your taps.

Is a Vaillant EcoFIT Pure 618 system the right boiler for my house or flat?

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

This Vaillant ecoFIT Pure 618 System boiler gets its power from gas and the power it's capable of producing is measured in kilowatts - the output rate is actually a kilowatt rate. The higher the output rate, the more kilowatts a boiler can use when heating water.

If you choose a boiler whose output rate is too low, it may not have enough power to make your water as hot as you would like. If you choose a boiler whose output rate is too high, you won't have to put up with lukewarm water but you will face higher gas bills.

The Vaillant EcoFIT Pure 618 system boiler has an output level of 19 kW, so which types of property would it be appropriate for?

A Gas Safe boiler installer would say that this Vaillant ecoFIT Pure 618 System boiler's level of output makes it suitable for installing in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

How large is the Vaillant EcoFIT Pure 618?

The Vaillant EcoFIT Pure 618 is 700 mm [H] by 390 mm [W] by 295 mm [D] in size.

Is the Vaillant EcoFIT Pure 618 condensing or non-condensing?

We recommend that, if possible, you select one of the very latest condensing gas boilers on the market like the Vaillant EcoFIT Pure 618.

Condensing boilers are better for the environment because they capture and recycle the heat still present in flue exhaust gases and water vapour condensation for re-use, meaning lower greenhouse gas emissions.

They're also a lot cheaper to run meaning that, if you're replacing a very old and inefficient boiler, the savings on your gas bill over 5-10 years add up to more than you pay for the boiler itself.

Is the Vaillant EcoFIT Pure 618 system a good choice for the environment?

How we heat our homes has become a major issue for many people worried about climate change and environmental issues in general.

Approximately 14% of the UK's greenhouse gas production is caused by our central heating systems. The gas boilers in larger urban areas of Britain are mainly responsible for emissions of toxic nitrogen dioxide.

Would installing a Vaillant EcoFIT Pure 618 system boiler in your home be a green choice? Let's look at the numbers.

All boilers manufactured in the UK from April 2018 must achieve a SEDBUK “A” grade and an energy efficiency rating of 92% or above. Before that, the minimum was 88% - efficiency ratings of 88% and 89% were scored a “B” and 90%+ an "A".

A boiler's energy efficiency rating describes how much energy it uses and wastes during its standard operation.

The energy efficiency of the Vaillant EcoFIT Pure 618 was rated at 94% with a SEDBUK grading of "A".

Energy-efficient boilers help the environment as they require less fuel and emit fewer harmful gases. In 2015, the EU introduced the Energy Related Products Directive (ERP) with the aim of ensuring that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

This legislation aims to conserve energy at all life cycle stages, from initial production through to actual use by a customer and up to the point of disposal.

The Vaillant EcoFIT Pure 618 has been given an ERP rating of "A".
