Vaillant ecoTEC Exclusive IQ 627 System Gas boiler frequently asked questions

Is the Vaillant EcoTEC Exclusive IQ 627 a system boiler, a combi boiler or a regular boiler?

If you are searching for a system boiler for your house or flat, the Vaillant EcoTEC Exclusive IQ 627 is certainly one to consider.

System boilers need a hot water cylinder to work but, unlike heat only boilers, they don't require a cold water tank. This can be advantageous if you live in an apartment, lack attic space, or are planning a loft conversion.

System boilers allow you to set the times when you want hot water to be available. Heated water is stored in the cylinder and can be used throughout the day. With a system boiler, if you forget to set the timer, you will have to wait a while for hot water.

The constant supply of hot water from the cylinder ensures that you can have multiple taps and showers in use without a loss of pressure to each point (something combi boilers struggle with). This makes a system boiler suitable for large families and homes with more than one bathroom.

Should I choose a Vaillant EcoTEC Exclusive IQ 627 system boiler for my house or flat?

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

Your boiler’s output is a measurement of the power it has available to heat the volume of water required for your taps and radiators. The higher the output rate, the more water it can heat.

You need to be careful to select a boiler with the optimal level of output for your property though. That's because, if your boiler output is too low, your water and radiators will often not be as hot as you want them to be. If the output is too high, you’ll be paying more for gas than you need to.

The output of the Vaillant EcoTEC Exclusive IQ 627 system is 27 kW, so which types of property would this Vaillant ecoTEC Exclusive IQ 627 System boiler be appropriate for?

Most heating engineers would recommend that this Vaillant ecoTEC Exclusive IQ 627 System boiler would be suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


What are the dimensions of the Vaillant EcoTEC Exclusive IQ 627 boiler?

The measurements of the Vaillant EcoTEC Exclusive IQ 627 are 720 mm by 440 mm by 338 mm.

Is the Vaillant EcoTEC Exclusive IQ 627 condensing or non-condensing?

We always recommend to clients that they select the very latest condensing boiler for their home.

Condensing boilers like the Vaillant EcoTEC Exclusive IQ 627 are more efficient with the gas they use in operation, meaning that you'll benefit from lower fuel bills. Condensing boilers are also better for the environment.

They achieve their efficiency by capturing and recycling the heat still present in the water vapour condensation and flue exhaust gases created when a boiler burns gas to get the energy it needs. It then reuses that recycled heat to perform a number of tasks, including heating the colder water that comes back to your boiler via the radiator.

What energy efficiency ratings have been awarded to the Vaillant EcoTEC Exclusive IQ 627 system?

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about climate change.

About 14% of the greenhouse gases we produce in the UK come from the power needed for central heating. In bigger British cities, gas boilers are a significant source of nitrogen dioxide emissions.

If you decide to install a Vaillant EcoTEC Exclusive IQ 627 system in your home, will you be helping the environment with your choice? Let’s have a look at the figures.

All boilers manufactured and installed in the UK are required to have an energy efficiency rating of 92% or above (or a good “A” SEDBUK rating). Before April 2018, when the law changed, the minimum energy efficiency level permissible was 88% (86-90% is a SEDBUK "B" rating and 90%+ is an "A" rating).

A boiler's energy efficiency rating indicates the amount of energy used and wasted during normal operational performance.

Following its assessment, the Vaillant EcoTEC Exclusive IQ 627 was given an efficiency rating of 94% and a SEDBUK grading of "A".

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 regulation aims to encourage manufacturers to create products that are more environmentally friendly and which reduce gas emissions associated with those products.

The ERP grading for the Vaillant EcoTEC Exclusive IQ 627 is "A".

Am I covered if the Vaillant EcoTEC Exclusive IQ 627 system boiler breaks down?

The Vaillant EcoTEC Exclusive IQ 627 boiler is covered by a parts and labour warranty of 5 years.

Vaillant ecoTEC Exclusive IQ 627 System Gas boiler frequently asked questions

Is the Vaillant EcoTEC Exclusive IQ 627 boiler a standard, combi or system model?

You may wish to consider installing the Vaillant EcoTEC Exclusive IQ 627 if you are looking for a system boiler for your house or flat.

System boilers need a hot water cylinder to work, which is normally situated in an airing cupboard or similar. However, unlike heat only boilers, system boilers don’t require a separate cold water tank, meaning they are a preferred option for some homeowners, especially those planning a loft conversion in the future.

They use (often built-in) circulating pumps to distribute hot water to your taps and radiators and installation is often easier from scratch with heat only boilers as there’s one less component (the water tank) to purchase and fit.

System boilers also need programming for heat and hot water and don’t offer this instantly. However, the cylinder can keep water hot for use afterwards so you shouldn’t have to wait around for your bath water so long as you set your timer and have it on long enough to heat the water you’ll need for the day.

Is a Vaillant EcoTEC Exclusive IQ 627 system boiler appropriate for my house or apartment?

Whether this Vaillant ecoTEC Exclusive IQ 627 System boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions - it means how powerful it is.

A boiler’s output is a measurement of the amount of power it can use to provide hot water to your taps and radiators. The higher its output rate, the more water it can heat.

If your new boiler’s output is too low, your hot water might not be as hot as you want it to be. If it's too high, you’ll be paying more for gas than you need to.

The output of the Vaillant EcoTEC Exclusive IQ 627 system boiler is 27 kW, so which types of property would this be appropriate for?

Most Gas Safe boiler installers would recommend that a boiler with this output level would be most suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


What are the proportions of a Vaillant EcoTEC Exclusive IQ 627 boiler?

The dimensions of the Vaillant EcoTEC Exclusive IQ 627 are 720 mm [H] x 440 mm [W] x 338 mm [D].

Is this Vaillant boiler non-condensing or condensing?

Because of their increased energy efficiency, we recommend to all customers that they select one of the latest condensing boilers. Condensing boilers capture the heat from water vapour condensation and flue exhaust gases and recycle that heat to warm water entering the boiler (for example, from your radiators).

The Vaillant EcoTEC Exclusive IQ 627 is a condensing gas boiler and choosing this model will result in a likely substantial reduction in your fuel bills, particularly if you're replacing an older, inefficient, non-condensing boiler.

How energy efficient is the Vaillant EcoTEC Exclusive IQ 627 system boiler?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.

Central heating systems are responsible for 14% of greenhouse gas emissions in the UK. You may also be aware that the gas boilers we use emit dangerous nitrogen dioxide in large volumes in the bigger British cities.

Would installing a Vaillant EcoTEC Exclusive IQ 627 system boiler in your home help combat climate change? What do the figures suggest?

The energy efficiency rating of the Vaillant EcoTEC Exclusive IQ 627 is 94% with a SEDBUK band rating of "A".

Energy efficiency tests record how much energy is wasted on non-core functions during an operation.

By law, all boilers manufactured and supplied in the UK must have a minimum energy efficiency performance level of 92% (equivalent to a SEDBUK "A" grade). Up to April 2018, the minimum performance level was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90%+ an "A" grade).

The ERP (or Energy Related Products Directive) is a European regulation governing products which require energy to operate throughout their lives and encourages manufacturers to create products that are more environmentally friendly.

The legislation is designed to reduce the potential for harmful gas emissions during manufacturing and actual use right through to the point of final disposal.

For the Vaillant EcoTEC Exclusive IQ 627, the ERP rating is "A".

How many years' warranty does the Vaillant EcoTEC Exclusive IQ 627 system come with?

The Vaillant EcoTEC Exclusive IQ 627 boiler comes with a 5 year warranty for parts and labour.
