Vaillant ecoTEC Plus 618 System Gas boiler frequently asked questions

Which category of boiler does the Vaillant EcoTEC Plus 618 fit into?

Looking for a gas system boiler for your flat or house? Then the Vaillant EcoTEC Plus 618 may be an option you should consider.

For homes that have a higher-than-average demand for hot water and heating and for larger properties, system boilers are a more suitable option than the more popular combi boilers.

Combi boilers heat water on demand but the amount of water they can actually deliver to taps is determined by the mains water pressure, flow rate and power. System boilers instead use a hot water cylinder that stores and keeps water hot throughout the day. As long as you remember to program the times you want hot water and the cylinder still has water left in it, you should have hot water whenever you need it.

And, unlike heat only boilers that also require a cold water storage tank to work (normally fitted in the loft), system boilers don't, meaning they're quicker, easier and cheaper to install.

Is the Vaillant EcoTEC Plus 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 EcoTEC Plus 618 system outputs at a maximum of 18 kW, so which types of property would this Vaillant ecoTEC Plus 618 System boiler be appropriate for?

A PlumbProud Gas Safe boiler installer would recommend that this Vaillant ecoTEC Plus 618 System boiler be installed in smaller homes and apartments with one bathroom and up to 10 radiators.


Where will the Vaillant EcoTEC Plus 618 fit in my house?

The dimensions of the Vaillant EcoTEC Plus 618 are 720 mm [H] x 440 mm [W] x 372 mm [D].

Is the Vaillant EcoTEC Plus 618 condensing or non-condensing?

We recommend that you select a condensing boiler like the Vaillant EcoTEC Plus gas Vaillant EcoTEC Plus 618 for your home if possible because of the environmental benefits and the money you'll save on your gas bills.

Condensing boilers are much more energy-efficient than older, non-condensing models as they capture and recycle the heat still present in the water vapour condensation and flue exhaust gases that your boiler creates when burning gas for reuse.

Is the Vaillant EcoTEC Plus 618 system considered environmentally friendly?

With environmental issues in the spotlight, more and more homeowners are becoming concerned about how they heat their homes and how much they're contributing towards combatting climate change.

Central heating creates 14% of the UK’s greenhouse gases. And in Britain's larger cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Would choosing the Vaillant EcoTEC Plus 618 system boiler be an environmentally friendly decision? Here's what the figures say.

All boilers manufactured in the UK from April 2018 must operate at a minimum level of energy efficiency of 92% ("A" rating on the SEDBUK scale). Before that, the minimum was 88% - boilers scoring 88/89% were given a SEDBUK "B" rating and 90% or above an "A" rating.

The energy efficiency score of a boiler indicates how much energy it uses and how much goes to waste when in use.

After its assessment, the Vaillant EcoTEC Plus 618 was given an efficiency rating of 94% and a SEDBUK grading of "A".

The Energy Related Products Directive grades products according to the energy they consume and the harmful gas emissions they create, from manufacturing right through to final disposal, including how they're used by customers between these two points.

The Vaillant EcoTEC Plus 618 is rated "A".

Is there a warranty on the Vaillant EcoTEC Plus 618 system boiler if it breaks down?

The parts and labour warranty on the Vaillant EcoTEC Plus 618 covers all repair-related costs for 5 years while the heat exchange warranty covers you for [Heat Exchange Warranty] years.

Vaillant ecoTEC Plus 618 System Gas boiler frequently asked questions

Is the Vaillant EcoTEC Plus 618 a standard, combi or system boiler?

The Vaillant EcoTEC Plus 618 is worthy of consideration if you're looking for a system boiler for your flat or house.

System boilers need a hot water cylinder to work - normally fitted inside an airing or landing cupboard or similar spot. Unlike heat only boilers, they do not require a separate cold water tank, making them a more suitable choice if you have no loft, lack space in the attic, or are planning to do a loft conversion.

These boilers distribute hot water around your home to your taps and radiators using (often built-in) circulating pumps and they're easier to install as there is one less component (the water tank) to find room for. A system boiler needs to be programmed to tell it what times you want heat and hot water - unlike combi boilers, they don't provide hot water on demand.

Is the Vaillant EcoTEC Plus 618 system boiler a suitable choice for my property?

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 gas bills will go up and not down.

The output of the Vaillant EcoTEC Plus 618 system is 18 kW, so which types of property would this Vaillant ecoTEC Plus 618 System boiler be an appropriate choice for?

Most heating engineers would suggest that the Vaillant EcoTEC Plus 618 system boiler would be a suitable choice for installation in smaller homes and apartments with up to 10 radiators and one bathroom.


What size is a Vaillant EcoTEC Plus 618 boiler?

The Vaillant EcoTEC Plus 618 is 720 mm [H] by 440 mm [W] by 372 mm [D] in size.

Is the Vaillant EcoTEC Plus 618 non-condensing or condensing?

The Vaillant EcoTEC Plus 618 is a condensing gas boiler - we’d strongly recommend that you choose the very latest condensing model for your home.

Condensing boilers run on either gas or oil and are manufactured specifically to improve energy efficiency. They do this by capturing and recycling the warmth present in flue exhaust gases and water vapour condensation into more usable heat the system can use, meaning they're far more efficient and cost less to run.

Is the Vaillant EcoTEC Plus 618 system an energy-efficient boiler?

With more and more people concerned about climate change, how we heat our homes and the damage it does to the environment is increasingly being questioned by British homeowners.

As much as 14% of the UK’s greenhouse gas production derives from our domestic central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in Britain's largest cities.

Would installing the Vaillant EcoTEC Plus 618 system in your home be an environmentally friendly decision? Let's look closely at the figures.

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 they are at least 88% efficient.

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

The Vaillant EcoTEC Plus 618 has been assigned an efficiency rating of 94% with a SEDBUK rating of "A".

The Energy Related Products Directive intends to encourage all manufacturers to reduce harmful gas emissions connected to the products they make, from the manufacturing stage to final disposal, including when they are in active use.

The Vaillant EcoTEC Plus 618 has an ERP rating of "A".

What is the warranty period on a Vaillant EcoTEC Plus 618 system boiler?

The Vaillant EcoTEC Plus 618 boiler has a warranty covering parts and labour costs for up to 5 years after installation.
