Vaillant ecoTEC Plus 424 heat only Gas boiler frequently asked questions

What kind of boiler is the Vaillant EcoTEC Plus 424 - standard, combi or system?

If you’re looking for a heat only boiler for your house or flat, you may wish to the consider the Vaillant EcoTEC Plus 424.

Heat only boilers, sometimes known as standard boilers, regular boilers or conventional boilers, are better for homes with multiple bathrooms or larger families where members of your household may need to use hot water at the same time as each other, such as a shower in the bathroom and a hot water tap in the kitchen. This is because, unlike combi boilers, they can handle demand from more than one point at a time with no drop in water pressure, temperature and volume.

Heat only boilers use a hot water cylinder with an immersion heater (normally installed in an airing or landing cupboard) and a cold-water tank (normally stored in the loft).

You program a heat only boiler to provide you with the central heating and hot water you need at specific times of the day, such as first thing in the morning. However, if you forget to set timings and there is no water left in the hot water tank, you may have to wait up to an hour before you have hot water again.

Would the Vaillant EcoTEC Plus 424 heat only be a suitable choice of 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 EcoTEC Plus 424 heat only outputs at a maximum of 24 kW, so which types of property would this Vaillant ecoTEC Plus 424 heat only boiler be appropriate for?

A PlumbProud boiler engineer would almost certainly recommend that this Vaillant ecoTEC Plus 424 heat only boiler is most suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

The dimensions of the Vaillant EcoTEC Plus 424 are 600 mm [H] x 375 mm [W] x 320 mm [D].

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

This Vaillant EcoTEC Plus 424 is a condensing gas boiler - we always recommend that clients choose the latest condensing models to benefit from the technology, which continues to improve year after year.

Condensing boilers capture the heat still present in flue exhaust gases and water vapour condensation, processing them through a secondary heat exchanger to, among other tasks, heat colder water returning from your radiators.

By selecting a modern condensing boiler, you'll save money on your gas bills as well as benefitting the wider environment.

Is the Vaillant EcoTEC Plus 424 heat only environmentally friendly?

How we heat our homes has become a major issue for many people worried about climate change and environmental issues in general.

A boiler's energy efficiency rating describes how much energy it uses and wastes during its standard operation.

The energy efficiency of the Vaillant EcoTEC Plus 424 was rated at 94% with a SEDBUK grading of "A".

Vaillant ecoTEC Plus 424 heat only Gas boiler frequently asked questions

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

If you are searching for a heat only boiler for your house or flat, the Vaillant EcoTEC Plus 424 is certainly one to consider.

If your home has more than one bathroom or you have a large family that uses a lot of hot water, a heat only boiler (sometimes called a standard boiler, a regular boiler or a conventional boiler) is likely to be the best option for you. Heat only boilers require both a hot water or immersion cylinder and a cold water tank. Once the water in the cylinder is heated, you can use this hot water throughout the day and it can feed multiple taps and showers at the same time.

This is in contrast to a combi boiler which can only heat a limited amount of water at any one time. This can cause a problem if two or more taps and showers are being used simultaneously as the water temperature, pressure and volume to all points will drop.

Heat only boilers allow you to program the times that you want heat and hot water to be available. However, if you forget to do this and the immersion cylinder is empty, you may have to wait up to an hour before hot water becomes available again.

If your property already has a water tank and cylinder, it will nearly always be cheaper to replace like for like instead of replacing it with a different type of boiler. In addition to new pipework, you may need to replace older radiators that may be unable to cope with the higher water pressure delivered by other types of boiler.

Is a Vaillant EcoTEC Plus 424 heat only the right boiler for my house or flat?

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?

A PlumbProud Gas Safe boiler installer would recommend that the level of output from this Vaillant ecoTEC Plus 424 heat only boiler would make it a suitable installation option for 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 measures 600 mm high and 375 mm wide by a depth of 320 mm.

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

The Vaillant EcoTEC Plus 424 is a condensing boiler – we recommend to all clients that they choose the very latest condensing boilers because their efficiency continues to improve year after year.

You will save money on your gas bills every year by choosing a condensing boiler as well as benefitting the environment.

Is the Vaillant EcoTEC Plus 424 heat only boiler 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.

Would installing the Vaillant EcoTEC Plus 424 heat only in your home be an environmentally friendly decision? Let's look closely at the figures.

All boilers manufactured after April 2018 in the UK must be rated as an “A” on the SEDBUK grading system, subject to a minimum energy efficiency rating of 92% or above. Before that, the minimum rate was 88% - boilers with an energy efficiency of 88% or 89% were given a “B” rating. Boilers scoring 90% or more were given an "A" rating.

The energy efficiency rating for a boiler describes the amount of energy it uses and how much goes to waste in operation.

The Vaillant EcoTEC Plus 424 has an efficiency rating of 94% with a SEDBUK grade of "A".
