Vaillant ecoTEC Plus 424 heat only Gas boiler frequently asked questions

Is the Vaillant EcoTEC Plus 424 boiler a standard, combi or system model?

The Vaillant EcoTEC Plus 424 boiler could be suitable for your house or flat if you are looking for a new heat only boiler.

Large family homes and properties with more than one bathroom benefit most from installing a heat only boiler (also referred to as a conventional boiler, a standard boiler or a regular boiler). Heat only boilers require both a cold water tank and hot water cylinder and an immersion heater. The immersion heater heats and keeps the water warm and feeds hot water to taps, radiators and other sources via the boiler.

Tell your boiler the times and days when you want hot water and central heating and it'll be there waiting for you. However, if you forget and there's no hot water left in your tank, you'll have to wait up to an hour before it's ready.

The biggest benefit of a heat only boiler is that, unlike a combi boiler, it’s possible to run two taps with hot water at the same time with no drop in pressure, volume or temperature (a known issue with combi boilers). It also means you can shower and have the dishwasher running at the same time without your water pressure being affected.

Is the Vaillant EcoTEC Plus 424 heat only boiler from the EcoTEC Plus range a suitable choice for my house or flat?

You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".

Your boiler should be able to cope with peak hot water demand in your property and not just your average hot water usage. The output rate of a boiler is measured in kilowatts and tells you how much power a boiler can use to provide hot water to your taps, showers and radiators.

If the output of your boiler is too low, there will often be times when your water isn't as hot as you want. But if your boiler output is too high, it will be more costly to run (often unnecessarily).

The output of the Vaillant EcoTEC Plus 424 heat only boiler is 24 kW kilowatts. Which types of property would this be appropriate for?

A boiler engineer would be likely to recommend that this Vaillant ecoTEC Plus 424 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.


Vaillant EcoTEC Plus 424 dimensions

Vaillant’s EcoTEC Plus 424 is 600 mm tall, 375 mm wide, and 320 mm deep.

Is the Vaillant EcoTEC Plus 424 a condensing or non-condensing boiler?

The Vaillant EcoTEC Plus 424 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.

Is the Vaillant EcoTEC Plus 424 heat only boiler good for the environment?

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.

With central heating being responsible for 14% of greenhouse gas emissions in the UK, your choice of boiler matters. Gas boilers are also responsible for the significant atmospheric volumes of dangerous nitrogen dioxide emissions in larger British cities.

Will installing a Vaillant EcoTEC Plus 424 heat only in your home be a positive contribution to the environment? The figures below will tell you more.

The energy efficiency rating of the Vaillant EcoTEC Plus 424 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).

In 2015, the Energy Related Products Directive (ERP) came into force. The legislation applies to all products that consume energy - in production, during their active life, and at the point of final disposal.

The ERP was introduced to incentivise manufacturers to create products that emit fewer harmful gases with the larger aim of protecting the wider environment.

The Vaillant EcoTEC Plus 424 has been awarded an ERP rating of "A".

Vaillant ecoTEC Plus 424 heat only Gas boiler frequently asked questions

Vaillant EcoTEC Plus 424 - a combi boiler, system boiler or regular boiler?

The Vaillant EcoTEC Plus 424 boiler could be suitable for your house or flat if you are looking for a new heat only boiler.

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.

Is the Vaillant EcoTEC Plus 424 heat only boiler the right choice for my house or apartment?

Whether this Vaillant ecoTEC Plus 424 heat only boiler is right for where you live depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output of a boiler is measured in kilowatts and indicates how much energy it can use to heat the water needed for your radiators, taps and showers. The greater the output, the more water it can heat.

A boiler whose output is too high will give you hot water and warm radiators but also higher gas bills, whereas a boiler whose output is too low will result in cheaper gas bills but the water might not always be as hot as you want it to be.

The output of the Vaillant EcoTEC Plus 424 heat only is 24 kW, so which types of property would this model be appropriate for?

An experienced Gas Safe boiler installer would recommend that, at this level of output, the most suitable type of property for this Vaillant ecoTEC Plus 424 heat only boiler would be medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


What are the dimensions of the Vaillant EcoTEC Plus 424 boiler?

The Vaillant EcoTEC Plus 424 is 600 mm high by 375 mm wide by 320 mm deep.

Is this Vaillant boiler condensing or non-condensing?

Condensing boilers like the Vaillant EcoTEC Plus 424 improve energy efficiency and reduce your annual expenditure on gas.

They do this by capturing and recycling the warmth still present in water vapour condensation and flue exhaust gases to, for example, increase the temperature of the colder water returning from your radiators.

Condensing boilers are also much better for the environment because they emit fewer greenhouse gases.

Is the Vaillant EcoTEC Plus 424 heat only good for the environment?

More and more homeowners are aware of the importance of how we heat our homes and its impact on climate change and other environmental issues.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

If you would like your next boiler to help in the fight against climate change, would the Vaillant EcoTEC Plus 424 heat only be a suitable choice?

All boilers manufactured and installed in the UK are required by law to have an energy efficiency rating of at least 92%, equivalent to a good “A” rating on the SEDBUK scale. Before this, the minimum was 88% (ratings of 88% and 89% are equivalent to a high “B” SEDBUK rating and anything 90% or higher is an "A" rating).

A boiler's energy efficiency rating is designed to let you know how much energy is used and wasted during normal functioning.

The Vaillant EcoTEC Plus 424 was given an efficiency rating of 94% and a band rating of "A".

In 2015, the Energy Related Products Directive (ERP) came into force. The legislation applies to all products that consume energy - in production, during their active life, and at the point of final disposal.

The ERP was introduced to incentivise manufacturers to create products that emit fewer harmful gases with the larger aim of protecting the wider environment.

The Vaillant EcoTEC Plus 424 has been awarded an ERP rating of "A".

What length of warranty does the Vaillant EcoTEC Plus 424 come with?

The Vaillant EcoTEC Plus 424 boiler is covered by a parts and labour warranty of 5 years.
