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

The Vaillant EcoFIT Pure 618 may be worth considering if you are looking for a system boiler for your house or flat.

System boilers require a hot water cylinder to work (normally stored in an airing or landing cupboard) but, unlike heat only boilers, they do not require a cold water tank. This makes them more suitable for homes that do not have lofts, where attic space is limited or where a loft conversion is being considered.

You program your heating and hot water to come on via the control panel. But if you forget to set the timer, you will have to wait a while for the water to heat up. Hot water is stored in the cylinder for use throughout the day and can be distributed to multiple showers and taps at the same time without a loss of pressure or temperature (something combi boilers really struggle with). For this reason, a system boiler is a suitable option for large families and homes with more than one bathroom.

As no cold-water tank is needed with a system boiler and many major system components are built into it, this type of boiler can be easier to install than a standard boiler.

Is the Vaillant EcoFIT Pure 618 system boiler suitable for my house or apartment?

You should make sure that the boiler you choose for your property is the right "size". And size doesn't mean its physical dimensions. Size means how much power it has - the "output".

A boiler's output level measures how much power it can use to provide you with the hot water you need for your radiators and taps. If a boiler has a high output rate, it can heat greater volumes of water.

If you choose a boiler with too low an output, you'll find that the water coming out of your taps and in your radiators won't be as hot as you want it to be. Choosing one whose output is too high means you'll pay more than you need to for the gas your boiler needs to work.

The Vaillant EcoFIT Pure 618 system outputs at a maximum of 19 kW, so which types of property would this Vaillant ecoFIT Pure 618 System boiler be appropriate for?

Most experienced heating engineers would suggest that the most suitable type of property for installing a Vaillant EcoFIT Pure 618 system boiler in would be medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

What dimensions does a Vaillant EcoFIT Pure 618 have?

The size of the Vaillant EcoFIT Pure 618 boiler is 700 mm high, 390 mm wide, and 295 mm deep.

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

Condensing boilers like the Vaillant EcoFIT Pure 618 improve energy efficiency and reduce your annual expenditure on gas.

They do this by capturing and recycling the warmth still present in water vapour condensation and flue exhaust gases to, for example, increase the temperature of the colder water returning from your radiators.

Condensing boilers are also much better for the environment because they emit fewer greenhouse gases.

Is the Vaillant EcoFIT Pure 618 system boiler good for the environment?

As more of us are increasingly concerned about climate change, how we heat our homes and its impact on the environment has become an issue of importance to homeowners.

Around 14% of the greenhouse gases produced in the UK is a result of our central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in some of our largest cities.

Would choosing the Vaillant EcoFIT Pure 618 system be an environmentally-friendly choice? If so, let's look at its performance figures.

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".
