Vaillant ecoFIT Pure 425 heat only Gas boiler frequently asked questions

Is the Vaillant EcoFIT Pure 425 a regular, combi or system boiler?

Vaillant’s EcoFIT Pure 425 is one you might consider if you’re looking for a heat only boiler for your house or flat.

Heat only boilers, also known as conventional boilers, standard boilers or regular boilers, require a hot water/immersion cylinder and a cold-water tank to work - the immersion cylinder is usually stored in a landing or airing cupboard and the cold water tank in your attic. Your water is kept hot throughout the day by the immersion cylinder.

You can schedule your hot water and heating at set times during the day, but if you forget to set your system and there's no hot water left, you'll have to wait for the immersion cylinder to heat your water for your bath or shower.

A heat only boiler is usually a better option if you have several bathrooms in your home or yours is a large household where there may be continual demand for hot water from different family members - combi boilers are not normally a suitable choice in these situations.

Is a Vaillant EcoFIT Pure 425 heat only boiler suitable for my house or flat?

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

Boiler output is measured in kilowatts and tells you how much power a boiler can use to heat the water your taps, showers and radiators need. The higher the output, the more power it has.

When choosing a boiler, you should choose one that can cope with the peak demand for hot water in your home and not just your typical usage.

If its output is too low, sometimes your hot water will not be hot enough, but if your boiler's output is too high for your needs, your gas bills will go up and not down.

The output of the Vaillant EcoFIT Pure 425 heat only is 25 kW, so which types of property would this Vaillant ecoFIT Pure 425 heat only boiler be an appropriate choice for?

An experienced boiler engineer would recommend that this Vaillant ecoFIT Pure 425 heat only boiler would provide adequate heating and hot water for medium-sized homes and larger apartments with up to 10-15 radiators and two bathrooms.


Vaillant EcoFIT Pure 425 size

The Vaillant EcoFIT Pure 425 measures 600 mm in height and has a width of 375 mm and a depth of 295 mm.

Is the Vaillant EcoFIT Pure 425 a non-condensing or condensing boiler?

The Vaillant EcoFIT Pure 425 boiler is a condensing gas boiler and we recommend that you select one of the latest models if possible.

Condensing boilers reduce homeowners' gas bills and are better for the environment. They do this by capturing and recycling the heat still present in the flue exhaust gases and water vapour condensation produced when boilers burn gas to generate the power they need to operate.

How does the Vaillant EcoFIT Pure 425 heat only boiler rate environmentally?

How we heat our homes and the effect that has on climate change has become important to many homeowners worried about the environment.

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.

Will choosing to install a Vaillant EcoFIT Pure 425 heat only in your home help the environment? Let's review the figures.

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 EcoFIT Pure 425 is rated as 94% energy efficient, equivalent to a "A" SEDBUK rating.

All products that consume energy throughout their lifespan must comply with the Energy Related Products (ERP) Directive.

Companies are legally obliged to reduce harmful gas emissions at all stages of a product's life cycle, from initial manufacturing right through to final disposal as well as when the product is in actual use.

The Vaillant EcoFIT Pure 425 scores "A".

Does the Vaillant EcoFIT Pure 425 heat only boiler come with a warranty?

Parts and labour charges incurred during a repair on the Vaillant Vaillant EcoFIT Pure 425 boiler are covered by a 2 year warranty.

Vaillant ecoFIT Pure 425 heat only Gas boiler frequently asked questions

What type of boiler is the Vaillant EcoFIT Pure 425?

Vaillant’s EcoFIT Pure 425 is one you might consider if you’re looking for a heat only boiler for your house or flat.

Heat only boilers (sometimes called conventional boilers, standard boilers or regular boilers) require both a hot water/immersion cylinder (normally in a landing cupboard or utility room) and a cold water tank (normally in the attic). The immersion cylinder keeps hot water warm and the cold water tank holds water which it transfers to the immersion cylinder when required.

You set the times that you need heat and hot water with a standard boiler. Once the water in the cylinder is heated, it can be used throughout the day. However, it takes a while for the water to heat up and so, if you haven't set your system, you will have to wait a while for heat and hot water to come back (normally no more than an hour).

Combi boilers deliver hot water instantly but there is a limit to the amount of water they can heat and distribute at any one time. Heat only boilers are usually better choices if you have a large family or more than one bathroom where more than one person in your household requires hot water at the same time.

Should I install a Vaillant EcoFIT Pure 425 heat only boiler in my house or apartment?

You should make sure that the boiler you install in your property is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

Your boiler has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your gas bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Vaillant EcoFIT Pure 425 heat only's output at 25 kW, which types of property would this Vaillant ecoFIT Pure 425 heat only boiler be most appropriate for?

A PlumbProud boiler engineer would almost certainly recommend that this Vaillant ecoFIT Pure 425 heat only boiler is most suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


Making space for the Vaillant EcoFIT Pure 425

The Vaillant EcoFIT Pure 425 measures 600 mm in height and has a width of 375 mm and a depth of 295 mm.

EcoFIT Pure 425 – condensing or non-condensing?

Condensing gas boilers like the Vaillant EcoFIT Pure 425 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.

Is the Vaillant EcoFIT Pure 425 heat only an energy-efficient boiler?

The effects of climate change on the environment are leading many homeowners to question the damage they might be doing by the way they heat their homes.

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.

Will installing a Vaillant EcoFIT Pure 425 heat only be a positive contribution to the environment? Let's see what the experts say.

The Vaillant EcoFIT Pure 425 has been awarded an efficiency rating of 94% and a SEDBUK band rating of "A".

In the UK, all boilers manufactured and supplied must have an energy efficiency rating of at least 92% or a SEDBUK "A" grade. Until April 2018, the minimum rating was 88% (88% and 89% are equivalent to a SEDBUK "B" rating and anything higher is rated "A").

A boiler's energy efficiency rating describes the amount of energy it uses and wastes when in normal operation.

Energy-efficient boilers help the environment as they require less fuel and emit fewer harmful gases. In 2015, the EU introduced the Energy Related Products Directive (ERP) with the aim of ensuring that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

This legislation aims to conserve energy at all life cycle stages, from initial production through to actual use by a customer and up to the point of disposal.

The Vaillant EcoFIT Pure 425 has been given an ERP rating of "A".

How long is the warranty period on a Vaillant EcoFIT Pure 425 heat only boiler?

The Vaillant EcoFIT Pure 425 boiler has a warranty covering parts and labour costs for up to 2 years after installation.
