Vaillant ecoTEC Exclusive IQ 627 System Gas boiler frequently asked questions

What type of boiler is the Vaillant EcoTEC Exclusive IQ 627?

The Vaillant EcoTEC Exclusive IQ 627 is worthy of consideration if you're looking for a system boiler for your flat or house.

If you choose a system boiler, you'll have to find somewhere to install a hot water cylinder too - they're normally located in an airing or landing cupboard. However, unlike regular boilers, they do not require a cold water tank to be fitted in the attic, making them suitable for homes with limited or no roof space or if you're planning a loft conversion in the future.

System boilers distribute the hot water to your taps and radiators using (often built-in) circulation pumps and are easier to install from scratch since they have one less component (the water tank) to consider.

System boilers also require programming to produce heat and hot water, so they cannot produce this instantly. Nonetheless, the cylinder keeps water hot for use later, so you don't have to wait as long as you set your timer and keep it on long enough to heat enough water.

Is the Vaillant EcoTEC Exclusive IQ 627 system suitable for my house or flat?

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

Your boiler should be able to cope with peak hot water demand in your property and not just your average hot water usage. The output rate of a boiler is measured in kilowatts and tells you how much power a boiler can use to provide hot water to your taps, showers and radiators.

If the output of your boiler is too low, there will often be times when your water isn't as hot as you want. But if your boiler output is too high, it will be more costly to run (often unnecessarily).

The output of the Vaillant EcoTEC Exclusive IQ 627 system boiler is 27 kW kilowatts. Which types of property would this be appropriate for?

An experienced Gas Safe boiler installer would be likely to recommend that this Vaillant ecoTEC Exclusive IQ 627 System boiler is capable of providing heating and hot water to 15 or more radiators and two or more bathrooms and would therefore be most suitable for larger properties including detached homes.


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

The dimensions of the Vaillant EcoTEC Exclusive IQ 627 are 720 mm tall, 440 mm wide, and 338 mm deep.

Is this Vaillant boiler condensing or non-condensing?

Condensing gas boilers like the Vaillant EcoTEC Exclusive IQ 627 are more energy-efficient and choosing one for your home will cut the amount you pay every year for your gas.

They do this by capturing the heat in water vapour condensation and in exhaust gases which would normally be expelled via the flue. They then recycle that heat, returning it to the system to, among other tasks, reheat colder water that is returning to your boiler from your radiators.

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

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.

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 the environmental impact of installing a Vaillant EcoTEC Exclusive IQ 627 system in your home be positive? Let's look at the numbers.

All boilers manufactured and supplied in the UK must achieve an energy efficiency rating of at least 92% (an "A" SEDBUK grade). This is higher than the previous 88%, which was a legal requirement prior to April 2018.

The energy efficiency rating is used to work out how much energy a boiler both uses and wastes when it's switched on and working correctly - its standard functioning and operation.

The Vaillant EcoTEC Exclusive IQ 627 is rated as 94% energy efficient, equivalent to a "A" SEDBUK rating.

The Energy Related Products (ERP) Directive is important European legislation that aims to limit energy use and harmful gas emissions during the manufacturing process, when the product is in use, and after it is disposed of.

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

How long is the warranty period on the Vaillant EcoTEC Exclusive IQ 627 system boiler?

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

Vaillant ecoTEC Exclusive IQ 627 System Gas boiler frequently asked questions

What type of boiler is the Vaillant EcoTEC Exclusive IQ 627?

If you’re looking for a system boiler for your house or flat, you may wish to the consider the Vaillant EcoTEC Exclusive IQ 627.

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.

Should I install a Vaillant EcoTEC Exclusive IQ 627 system boiler in my home?

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 Exclusive IQ 627 system outputs at a maximum of 27 kW, so which types of property would this Vaillant ecoTEC Exclusive IQ 627 System boiler 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 dimensions of the Vaillant EcoTEC Exclusive IQ 627 boiler?

The Vaillant EcoTEC Exclusive IQ 627 stands at 720 mm tall, 440 mm wide and 338 mm deep.

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

This Vaillant EcoTEC Exclusive IQ 627 is a condensing gas boiler - we always recommend that clients choose the latest condensing models to benefit from the technology, which continues to improve year after year.

Condensing boilers capture the heat still present in flue exhaust gases and water vapour condensation, processing them through a secondary heat exchanger to, among other tasks, heat colder water returning from your radiators.

By selecting a modern condensing boiler, you'll save money on your gas bills as well as benefitting the wider environment.

Is the Vaillant EcoTEC Exclusive IQ 627 system rated as 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.

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 EcoTEC Exclusive IQ 627 system boiler in your home be a green choice? Let's look at the numbers.

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

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 Energy Related Products (ERP) Directive is important European legislation that aims to limit energy use and harmful gas emissions during the manufacturing process, when the product is in use, and after it is disposed of.

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