Vaillant ecoFIT Pure 425 heat only Gas boiler frequently asked questions

What type of boiler is the Vaillant EcoFIT Pure 425?

If you are searching for a heat only boiler for your house or flat, the Vaillant EcoFIT Pure 425 is certainly one to consider.

Heat only boilers are also referred to as regular boilers, conventional boilers or standard boilers. Heat only boilers require both a hot water/immersion cylinder (usually stored in a landing cupboard or airing cupboard) and a cold water tank (usually stored in a loft) to work. Water passes from the cold tank to the immersion cylinder and the immersion cylinder heats and keeps water warm.

You program your immersion cylinder via the control panel to make sure that you have the hot water and central heating you need. However, if you forget to set your system and there's no water left in the immersion cylinder, it can take up to an hour before you'll have hot water again.

If your home has more than one bathroom or you have a large family and there's a high demand for hot water, a heat only boiler is often a more suitable option than a combi boiler. Although combis offer space-saving advantages, there is a maximum volume of water they can heat at any given time. This means that, if two or more people in your household want hot water at the same time, there will likely be a drop in temperature, volume and pressure to both points.

Would the Vaillant EcoFIT Pure 425 heat only boiler be suitable for my house or flat?

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 boiler engineer would be likely to recommend that this Vaillant ecoFIT Pure 425 heat only boiler is capable of providing heating and hot water to 10-15 radiators and two bathrooms and would therefore be most suitable for medium-sized homes and larger apartments.


How big is the Vaillant EcoFIT Pure 425?

The Vaillant EcoFIT Pure 425 is 600 mm [H] by 375 mm [W] by 295 mm [D] in size.

Is the Vaillant EcoFIT Pure 425 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 425 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 425 heat only boiler rated as environmentally friendly?

With more and more people concerned about climate change, how we heat our homes and the damage it does to the environment is increasingly being questioned by British homeowners.

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

Is the Vaillant EcoFIT Pure 425 heat only boiler an environmentally friendly choice for your home? Here’s what the figures say.

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 425 scored an efficiency rating of 94% and a SEDBUK band rating of A.

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 EcoFIT Pure 425, the ERP Heat rating is "A".

What length of warranty does the Vaillant EcoFIT Pure 425 come with?

A parts and labour warranty of 2 years is included with the Vaillant Vaillant EcoFIT Pure 425 boiler.

Vaillant ecoFIT Pure 425 heat only Gas boiler frequently asked questions

Is the Vaillant EcoFIT Pure 425 a combi boiler, system boiler or regular 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 (often referred to as conventional boilers, standard boilers or regular boilers) consist of a large cold water tank, hot water cylinder with an immersion heater, and a control panel. The cold water tank is often situated in a loft or attic while the hot water cylinder tends to be located in an airing or landing cupboard.

The major advantage of a heat only boiler compared to the more contemporary combi boiler is that it’s possible to run more than one appliance requiring hot water at the same time. With a combi boiler, switching two hot water taps on at the same time will lead to a drop in water pressure, temperature and volume to both points.

Best suited for larger homes, you can program hot water and central heating for times and days that suit you and your family. However, if you forget to set the timer and your hot water cylinder is empty, then you may have to wait up to an hour before you run a bath.

Would the Vaillant EcoFIT Pure 425 heat only be a suitable choice of boiler 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.

The output rate of a boiler tells you how much power it has available to it for heating the water that comes out of your taps and warms your radiators. A higher output rate means that your boiler has more power at its disposal.

You need to make sure you select a boiler with the right output rate. That's because, if your output rate is too high, then your boiler will have more power than it needs but it will cost too much to run. If the output rate is too low, your water may often not be hot enough.

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

An experienced PlumbProud Gas Safe boiler installer would recommend that this Vaillant ecoFIT Pure 425 heat only boiler is suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


Vaillant EcoFIT Pure 425 size

The Vaillant EcoFIT Pure 425 stands at 600 mm tall, 375 mm wide and 295 mm deep.

EcoFIT Pure 425 – non-condensing or condensing?

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

Condensing boilers like the Vaillant EcoFIT Pure 425 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 heat only Vaillant EcoFIT Pure 425 boiler energy efficient?

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.

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.

Would the environmental impact of installing a Vaillant EcoFIT Pure 425 heat only in your home be positive? Let's look at the numbers.

Boilers manufactured after April 2018 in the UK must achieve an "A" on the SEDBUK grading system as well as score a minimum of 92% on a separate energy efficiency test. Prior to that, the minimum was 88% - boilers rated at 88% and 89% were given a “B” rating (90% and higher were given an "A").

An energy efficiency rating describes how much energy the boiler uses and how much it wastes when in use.

The Vaillant EcoFIT Pure 425 was awarded an efficiency rating of 94% with a SEDBUK grading of "A".

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

Its purpose is to encourage manufacturers to offer products that are kinder to the environment by reducing harmful gas emissions at all stages, from production and end use right through to disposal.

The ERP rating for the Vaillant EcoFIT Pure 425 is "A".

How long is the warranty offered by the manufacturer for the Vaillant EcoFIT Pure 425 boiler?
