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 may be worth considering if you are looking for a combi boiler for your house or flat.

Combination or combi boilers are highly efficient and save a lot of space in your home. Combi boilers heat water directly from the mains when you turn on a tap and, as a result, you don’t need a hot water storage cylinder or a cold water tank in the roof space.

These boilers are, therefore, suitable for smaller homes and especially those without a loft. They are also cost-effective as the water is heated instantly and distributed on demand rather than being stored. Combi boilers are the most popular type of boilers in the UK and replacing an older boiler with a new combi boiler will reduce your gas bills significantly.

However, there are downsides to this type of boiler. If you take a shower while someone else is using a tap, less water will reach each point of usage at lower rates of pressure and temperatures as combi boilers can only heat a certain volume of water at any given time.

Is a Vaillant EcoFIT Pure 825 combi the right boiler for my house or flat?

Whether this Vaillant ecoFIT Pure 825 Combi 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 EcoFIT Pure 825 combi boiler is 25 kW, so which types of property would this be appropriate for?

A boiler engineer would recommend that, at this level of output, the most suitable type of property for this Vaillant ecoFIT Pure 825 Combi boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.

You need to consider the flow rate as well as the output rate when choosing a combi boiler.

Flow rates, measured in litres per minute, indicate how much water your boiler can heat and distribute around your home at any given time. If your family regularly use hot water around the house at the same time and you have a lot of radiators, you should choose a boiler with a high flow rate. This Vaillant ecoFIT Pure 825 Combi boiler's flow rate is 10 L/m.

However, you also need to consider the flow rate of your local mains water supply. Combis can only draw water from the mains as fast as the pipes can deliver it. If you choose a boiler with a 14l/m flow rate and the mains pipes into your home have a flow rate of 12l/m, your boiler won't be able to operate at full capacity. In other words, try to make sure the local water pressure and your boiler flow rates are as close as possible.

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.


Vaillant EcoFIT Pure 825 dimensions

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

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

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

Condensing boilers like the Vaillant EcoFIT Pure 825 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.

Is the Vaillant EcoFIT Pure 825 combi boiler rated as environmentally friendly?

With growing concern among the public about accelerating climate change, how we heat our homes and the impact this has on the environment has become a major topic of concern for many homeowners.

In the UK, central heating systems account for 14% of greenhouse gas production. Gas boilers in particular are responsible for emissions of dangerous nitrogen dioxide in British cities.

Will installing a Vaillant EcoFIT Pure 825 combi be a positive contribution to the environment? Let's see what the experts say.

All new British boilers must perform to a legal minimum energy efficiency of 92% (a low to good SEDBUK "A" rating). Prior to April 2018, the target was 88% (86-90% = SEDBUK "B" and 90%+ = SEDBUK "A").

Efficiency ratings are intended to let consumers know how much energy a boiler uses in its day-to-day activities and how much energy goes to waste.

The Vaillant EcoFIT Pure 825 was awarded an efficiency rating of 94%, equivalent to a SEDBUK grade of "A".

The ERP (or Energy Related Products Directive) is European legislation affecting products that consume energy throughout their lifetime.

The aim is to encourage companies to create environmentally friendlier products that reduce harmful gas emissions during manufacturing and when in use by the end client, right through to their eventual disposal.

In the case of the Vaillant EcoFIT Pure 825, the ERP rating is "A" for heat and "A" for hot water production.

How long is the warranty period on a Vaillant EcoFIT Pure 825 combi boiler?

The Vaillant EcoFIT Pure 825 is supplied with a parts and labour warranty of 2 years.

Vaillant ecoFIT Pure 825 Combi Gas boiler frequently asked questions

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

The Vaillant EcoFIT Pure 825 is a gas combi boiler.

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?

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 EcoFIT Pure 825 combi outputs at a maximum of 25 kW, so which types of property would this Vaillant ecoFIT Pure 825 Combi boiler 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.

You need to consider the flow rate as well as the output rate when choosing a combi boiler.

Flow rates, measured in litres per minute, indicate how much water your boiler can heat and distribute around your home at any given time. If your family regularly use hot water around the house at the same time and you have a lot of radiators, you should choose a boiler with a high flow rate. This Vaillant ecoFIT Pure 825 Combi boiler's flow rate is 10 L/m.

However, you also need to consider the flow rate of your local mains water supply. Combis can only draw water from the mains as fast as the pipes can deliver it. If you choose a boiler with a 14l/m flow rate and the mains pipes into your home have a flow rate of 12l/m, your boiler won't be able to operate at full capacity. In other words, try to make sure the local water pressure and your boiler flow rates are as close as possible.

The Vaillant EcoFIT Pure 825 is 700 mm high by 390 mm wide by 295 mm deep.

Vaillant EcoFIT Pure 825 – non-condensing or condensing?

The Vaillant EcoFIT Pure 825 is a condensing gas boiler - we strongly suggest that you choose either this model or a recently released model if at all possible.

A condensing boiler captures and recycles the warmth present in flue exhaust gases and water vapour condensation created by the burning of gas to warm up the water coming back into your boiler - for example, from your radiators.

Condensing boilers cost less to run (lower gas bills) and are better for the environment.

Is the Vaillant EcoFIT Pure 825 combi environmentally friendly?

As the British public has become more conscious of climate change, many homeowners consider the environment when choosing how to heat their homes.

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.

Will choosing a Vaillant EcoFIT Pure 825 combi boiler for your home be positive for the environment? Let's examine the figures.

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 Directive (ERP) came into force in 2015. This legislation was introduced to encourage manufacturers to create more energy-efficient products and it covers all products that consume energy during their lifetimes, including energy used during production and at the point of disposal.

ERP ratings of "A" for heat and "A" for water were assigned when testing the Vaillant EcoFIT Pure 825.

How long is the warranty offered by the manufacturer for the Vaillant EcoFIT Pure 825 boiler?

The parts and labour warranty offered with this Vaillant ecoFIT Pure 825 Combi boiler covers you for 2 years.
