Vaillant ecoFIT Pure 825 Combi Gas boiler frequently asked questions

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

Looking for a gas combi boiler for your flat or house? Then the Vaillant EcoFIT Pure 825 may be an option you should consider.

In older British homes, traditional boilers required you to find room for one or more storage tanks. One tank would keep hot water warm and the other stored cold water for later heating. Manufacturers introduced combi boilers to the UK in the 1970s so that homeowners could get the warmth and hot water they needed without having to sacrifice too much valuable space – remember that residential property in this country is among the smallest in the Western world.

Combi boilers deliver hot water to your radiators and taps using water they draw directly from the mains supply. As mains water travels through a combi boiler, the technology within it heats the cold water instantly and on demand. The hot water is then distributed throughout your house.

Combi boilers have one drawback, however: they can only heat a certain amount of water within a given time. For example, if someone uses the shower and another person uses the hot water tap at the same time, water pressure drops because water reaches each point differently.

Would the Vaillant EcoFIT Pure 825 combi be a suitable boiler for my house or flat?

It's best to choose a boiler whose size or "output" is right for your property. With boilers, however, size does not mean how big a boiler is, it means how much power it has.

The output of a boiler is measured in kilowatts and tells you how much power it has available to heat the water it sends to your hot taps, showers and radiators. The greater the demand for hot water in your home, the larger the output you will need.

It is important to select a boiler with the optimal output rate. Choose one with too high an output and your gas bills will be too expensive. Choose one with too low an output and sometimes the water in your radiators and coming out of your taps will be barely lukewarm.

The output of the Vaillant EcoFIT Pure 825 combi is 25 kW kilowatts, so which types of property would this be most suitable for?

A PlumbProud boiler engineer would recommend that this Vaillant ecoFIT Pure 825 Combi boiler is suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

As well as the output rate, you need to consider "flow rate" when choosing a combi boiler.

The flow rate describes how much water a combi boiler can draw from the mains, instantly heat, and then send to your radiators. Flow rates are measured in litres per second and this Vaillant ecoFIT Pure 825 Combi boiler's flow rate is 10 L/m.

The water in your mains pipe also has its own flow rate - normally between 10 and 12l/m in most parts of Britain. This means that, if you choose a combi boiler with a flow rate of 17l/m where local water pressure is 11lm, it won't actually process more water because of the slower flow rate of the mains.

In addition, larger households with more than one bathroom, multiple radiators, and where family members may want to use hot water at the same time (like morning showers) may actually need a boiler with a higher flow rate than either the boiler or the local mains pipe.

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.


Making space for the Vaillant EcoFIT Pure 825

The measurements of the Vaillant EcoFIT Pure 825 are 700 mm by 390 mm by 295 mm.

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

The Vaillant EcoFIT Pure 825 is a condensing gas boiler - this is the type of boiler we recommend to most clients because they're better for the environment and they will save money on annual fuel bills.

A condensing boiler captures and recycles the warmth still present in both the flue exhaust gases and water vapour condensation created when gas is burned to provide your boiler with power.

This means it needs less gas to operate and it uses this extra energy to perform a number of tasks, including heating the colder water that comes back to the boiler from the radiators in your home.

How energy efficient is the Vaillant EcoFIT Pure 825 combi?

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.

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

The energy efficiency rating for a boiler describes the amount of energy it uses and wastes during operation and there are two different ways to measure it.

All boilers manufactured and supplied in the UK must have a SEDBUK rating of “A” subject to a minimum energy efficiency score of 92% or above. Before April 2018, the minimum energy efficiency score was 88% (88/89% = "B" SEDBUK rating, 90%+ = "A" SEDBUK rating).

The Vaillant EcoFIT Pure 825 scored an efficiency rating of 94% and a SEDBUK band rating of A.

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.

Vaillant ecoFIT Pure 825 Combi Gas boiler frequently asked questions

Which category of boiler does the Vaillant EcoFIT Pure 825 fit into?

The Vaillant EcoFIT Pure 825 is a combi boiler you may wish to consider if you want this type of boiler for your house or flat.

In the past, most boilers needed one or more storage tanks to operate - one to store warm water and the other for storing water to be heated later. But storage tanks are problematic in properties where space is at a premium and particularly where there is no loft. Many properties in the UK are small and so manufacturers introduced combi boilers in the 1970s to eliminate the need for tanks.

With a combi boiler, the hot water for your radiators and taps is delivered on demand. The boiler instantly heats water it draws directly from the mains internally. It then distributes the heated water around your home at mains pressure as you need it.

It is important to bear in mind that, while combi boilers have many benefits, they can only heat a certain volume of water at any given time. This means that, if you run a shower at the same time as someone else is doing the washing up in the kitchen, the volume of water passing to each point will drop, causing a fall in pressure.

Would the Vaillant EcoFIT Pure 825 combi be a suitable choice of boiler 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 experienced heating engineers would likely recommend that, at this level of output, this Vaillant ecoFIT Pure 825 Combi boiler would be a suitable choice for smaller homes and apartments with up to 10 radiators and one bathroom.

The Vaillant EcoFIT Pure 825 is a combi boiler, which that means that you need to take the flow rate (measured in litres per minute) into account as well as the output rate. This Vaillant ecoFIT Pure 825 Combi boiler's flow rate is 10 L/m.

Combis draw water from the mains, instantly heating and distributing it where it's needed - taps, radiators, bathrooms, and so on.

However, this means that the flow rate of a boiler may effectively be capped by the flow rate of the mains water supply. For example, if your mains pressure is 12l/m, that is the maximum flow rate that your boiler can achieve even if you choose a boiler with a flow rate of 18l/m.

In addition, if your home has more than one bathroom, a high number of radiators, and more than one member of your household wants to use hot water at the same time regularly, the flow rate of both the boiler and the mains water pressure may not be high enough.

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.


What dimensions does a Vaillant EcoFIT Pure 825 have?

The Vaillant EcoFIT Pure 825 boiler is 700 mm high, 390 mm wide, and 295 mm deep.

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

The Vaillant EcoFIT Pure 825 is a condensing gas boiler - in fact, we recommend that you select this model or one of the latest condensing boilers on the market as the technology continues to improve over time.

Condensing boilers capture the heat still present in the flue exhaust gases and water vapour condensation created when the gas is burned and they recycle this back into the heating system to warm up the cold water re-entering the boiler from your radiators.

They're much more environmentally friendly and installing one results in much lower annual gas bills.

Is the Vaillant EcoFIT Pure 825 combi a good choice for the environment?

Price and performance are two important issues when choosing a boiler but now, for many people in the UK, so is the environmental impact of how we heat our homes and its effect on climate change.

In Britain's bigger cities, gas boilers, in particular, are responsible for dangerous levels of nitrogen dioxide emissions. Overall, 14% of all of the UK’s greenhouse gas production comes from heating our homes.

Let's take a closer look at whether installing a Vaillant EcoFIT Pure 825 combi would be a good choice for the environment.

Boilers manufactured and installed in the UK are assigned energy efficiency ratings following testing to an agreed set of standards. These scores indicate how much energy the boiler uses and how much goes to waste when it's in operation.

By law, boilers must achieve a SEDBUK rating of "A" subject to achieving a minimum of 92% energy efficiency. Prior to April 2018, the minimum was 88% (88% and 89% on the SEDBUK are graded "B" and 90% and above is graded "A").

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

The Energy Related Products Directive, also known as ERP, is European legislation that intends to reduce energy consumption related to products right from the initial manufacturing process through to eventual final disposal.

The purpose of the directive is to encourage manufacturers to create new products that are kinder to the environment and which result in lower overall harmful gas emissions through a product's entire life cycle.

The Vaillant EcoFIT Pure 825 has a rating of "A" for heat and "A" for water.

Is this Vaillant EcoFIT Pure 825 combi covered by a warranty?

The Vaillant EcoFIT Pure 825 boiler comes with a 2 year warranty for parts and labour.
