Vaillant ecoFIT Pure 825 Combi Gas boiler frequently asked questions

Is the Vaillant EcoFIT Pure 825 a combi, system or regular boiler?

The Vaillant EcoFIT Pure 825 is an option you may wish to consider if you’re looking for a combi boiler for your house or flat.

Traditionally, most boilers required you to find space in your property for one or more large storage tanks. These tanks would either keep water warm or hold it in reserve for later heating. Manufacturers originally introduced combi boilers to offer homeowners the same level of warmth and hot water without taking up as much space – remember that the UK has some of the smallest homes in the Western world.

With a combi boiler, the hot water needed for your radiators and taps is provided on demand. Water from the mains passes through your combi boiler and the technology within it instantly heats the cold water. It then distributes that hot water around your home.

The biggest drawback for combi boilers is that they have a maximum capacity in volume for heating water. This means that if someone wants to use the shower while another person wants to use a hot water tap, the amount of water reaching each point falls, resulting in a drop in water pressure.

Is the Vaillant EcoFIT Pure 825 combi 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 the boiler is - it means how big its "output" is.

This Vaillant ecoFIT Pure 825 Combi 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 825 combi boiler has an output level of 25 kW, so which types of property would it be appropriate for?

Most boiler engineers would recommend that a boiler with this output level would be most suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

With all combi boilers, you need to consider the "flow rate" as well as the output rate when making your decision.

Like all combi boilers, the Vaillant EcoFIT Pure 825 draws water from the mains. It instantly heats that water and then distributes it to the parts of your home which need it - taps, radiators, bathrooms, and so on. This Vaillant ecoFIT Pure 825 Combi boiler's flow rate is 10 L/m.

There is no benefit to purchasing a boiler with a high flow rate if the local water pressure is not that good - a high flow rate doesn't mean that your combi can draw more water from the mains.

In addition, if you live in a home with a large number of radiators and more than one bathroom and if more than one person regularly wants to use hot water at a time, a combi boiler may struggle to provide enough water at a hot enough temperature.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


Where will the Vaillant EcoFIT Pure 825 fit in my house?

Vaillant’s EcoFIT Pure 825 is 700 mm tall, 390 mm wide, and 295 mm deep.

Is the Vaillant EcoFIT Pure 825 condensing or non-condensing?

This Vaillant EcoFIT Pure 825 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 EcoFIT Pure 825 combi an energy-efficient boiler?

How we heat our homes is an issue which many homeowners worry about as the world combats climate change and environmental damage.

In the largest cities of Britain, gas boilers are responsible for dangerous levels of atmospheric nitrogen dioxide emissions. In total, 14% of the UK’s greenhouse gases are produced by central heating systems.

Would installing a Vaillant EcoFIT Pure 825 combi boiler in your home be a green choice? Let's look at the numbers.

Under current UK law, all boilers must achieve a minimum energy efficiency level of 92% (a low to good SEDBUK "A" rating). The minimum level was raised from its previous 88% in April 2018.

Energy efficiency scores are intended to inform consumers of the amount of energy used and wasted when a boiler is in normal operation.

The Vaillant EcoFIT Pure 825 was awarded an efficiency rating of 94% with a SEDBUK band rating of "A".

The Energy Related Products (ERP) Directive is a European directive which applies to all products that consume energy over their lifetime.

It encourages companies to create products that are environmentally friendlier at all life cycle stages, including initial manufacturing and end use through to final disposal, with the aim of reducing harmful gas emissions.

The Vaillant EcoFIT Pure 825 is rated "A" for heat and "A" for water.

Will I be covered if the Vaillant EcoFIT Pure 825 combi breaks down?

The manufacturer offers a parts and labour warranty of 2 years on the Vaillant EcoFIT Pure 825 boiler to new customers.

Vaillant ecoFIT Pure 825 Combi Gas boiler frequently asked questions

Is the Vaillant EcoFIT Pure 825 boiler a standard, combi or system model?

If you are searching for a combi boiler for your house or flat, the Vaillant EcoFIT Pure 825 is certainly one to consider.

Traditional boilers would require you to install one or more storage tanks in your property. These tanks either kept the water warm or stored it for later heating. Manufacturers initially designed and introduced combi boilers to the market to offer homeowners the highest levels of warmth and unlimited hot water without taking up as much space.

Combi boilers provide hot water on demand for your radiators and taps. They take water directly from the mains, heat it immediately as it's needed, and then distribute the hot water around your home.

Combi boilers, however, are limited in terms of how much water they can heat at any given time. For example, if one person wishes to take a shower while another wants to turn on a hot water tap, the amount of water reaching each point drops. This results in a drop in the water pressure as well as the temperature.

Is the Vaillant EcoFIT Pure 825 combi suitable for my house or flat?

Selecting the right boiler for your property means selecting a boiler that is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - its "output".

The output rate tells you how much energy your boiler has to use to provide you and your family with hot water and central heating. A higher output rate means that it can heat greater volumes of water.

Please be aware, though - if you choose a boiler whose output is too low, the water in your radiators and coming from your taps may not be warm enough. Conversely, if you choose a boiler with too high an output, you'll pay more for gas than is necessary.

The Vaillant EcoFIT Pure 825 combi boiler has an output level of 25 kW, so which types of property would it be appropriate for?

Most heating engineers would suggest that the Vaillant EcoFIT Pure 825 combi boiler would be a suitable choice for installation in smaller homes and apartments with up to 10 radiators and one bathroom.

Homeowners considering fitting a combi boiler to their home need to consider flow rates as well as output rates.

The flow rate is a measurement of the volume of water a combi can instantly heat and send to the taps and radiators around your home. The higher the likely demand for hot water in your home, the higher your combi's flow rate should be. This Vaillant ecoFIT Pure 825 Combi boiler's flow rate is 10 L/m.

Unlike heat only or system boilers, combi boilers don't store hot water in a tank for later use - instead, they draw it directly from the mains. This means that the volume of water your boiler can actually process is constrained by the flow rate of water in the mains pipe.

So, if you choose a combi boiler with a 15l/m flow rate but the flow rate in your mains pipe is 12l/m, the combi boiler's working flow rate is also 12l/m.

Combi boilers are also not always the correct choice for homes with multiple bathrooms, a high number of radiators, or where more than one family member will want to use hot water at the same time.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


How large is a Vaillant EcoFIT Pure 825 boiler?

The Vaillant EcoFIT Pure 825 stands at 700 mm tall, 390 mm wide and 295 mm deep.

EcoFIT Pure 825 – condensing or non-condensing?

We recommend that you choose a condensing boiler wherever possible like the Vaillant EcoFIT Pure 825 - try to go for the latest model, if possible, to take advantage of improving technology.

Condensing boilers capture and recycle the warmth still present in the water vapour condensation and in flue exhaust emissions created by burning gas to make them more efficient and economical to run.

You will save money on your gas bills too, plus condensing boilers are friendlier to the environment.

Is the Vaillant EcoFIT Pure 825 combi an energy-efficient boiler?

With more and more of us concerned about environmental issues and climate change, how we heat our homes has become an important issue to many homeowners.

The power we need for our central heating systems accounts for around 14% of the UK’s greenhouse gas production. There are often dangerous levels of ambient nitrogen dioxide gases in the atmospheres of British cities because of our use of gas boilers.

If you would like your next boiler to help in the fight against climate change, would the Vaillant EcoFIT Pure 825 combi be a suitable choice?

The energy efficiency rating of the Vaillant EcoFIT Pure 825 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 Energy Related Products Directive intends to encourage all manufacturers to reduce the harmful gas emissions associated with the products they make, from the manufacturing stage to final disposal, including when they are in active use.

The Vaillant EcoFIT Pure 825 has an ERP rating of "A" for heat and "A" for hot water.

Does the Vaillant EcoFIT Pure 825 combi boiler come with a warranty?

The Vaillant EcoFIT Pure 825 boiler offers a parts and labour warranty of 2 years.
