Vaillant ecoTEC Plus 424 heat only Gas boiler frequently asked questions

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

If you are considering installing a heat only boiler in your house or flat, then the Vaillant EcoTEC Plus 424 boiler is certainly worth investigating.

Also known as standard boilers, regular boilers or conventional boilers, heat only boilers feature both a hot water/immersion cylinder (normally found in a utility room or landing cupboard) and a cold water tank (normally found in an attic).

Heat only boilers enable you to program in times when you want heating and hot water to be available. If you forget to set the times and there's no water left in the hot water cylinder, you may have to wait up to an hour to run a bath or shower.

If your home has more than one bathroom or you have a large family, a heat only boiler would be a good choice because it can service demand for hot water from multiple points at the same time. This is in contrast to a combi boiler which can only heat a limited volume of water at any one time meaning that, when two or more points want hot water, the water delivered is cooler and lower in both volume and pressure.

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

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".

Output measures in kilowatts how much power a boiler can use when heating water for your radiators or taps. The higher the output rate, the more water it can heat.

If the output rate is too low, your hot water might often be only lukewarm, and if it is too high, you will be paying more for your gas than you need to.

The Vaillant EcoTEC Plus 424 heat only boiler has an output of 24 kW, so which types of property would it be most appropriate for?

An experienced PlumbProud Gas Safe boiler installer would recommend that this Vaillant ecoTEC Plus 424 heat only boiler is suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


Making space for the Vaillant EcoTEC Plus 424

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

Is this Vaillant boiler condensing or non-condensing?

The Vaillant EcoTEC Plus 424 is a condensing gas boiler - this is the type of boiler we recommend to most clients because they're better for the environment and they will save money on annual fuel bills.

A condensing boiler captures and recycles the warmth still present in both the flue exhaust gases and water vapour condensation created when gas is burned to provide your boiler with power.

This means it needs less gas to operate and it uses this extra energy to perform a number of tasks, including heating the colder water that comes back to the boiler from the radiators in your home.

How does the Vaillant EcoTEC Plus 424 heat only boiler rate environmentally?

How we heat our homes has become a pressing issue of concern for many homeowners worried about climate change and the environmental impact of their personal choices.

In the largest cities of Britain, gas boilers are responsible for dangerous levels of atmospheric nitrogen dioxide emissions. In total, 14% of the UK’s greenhouse gases are produced by central heating systems.

Would choosing the Vaillant EcoTEC Plus 424 heat only be an environmentally-friendly choice? If so, let's look at its performance figures.

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 EcoTEC Plus 424 was awarded an efficiency rating of 94%, equivalent to a SEDBUK grade 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".

How long is the warranty period on a Vaillant EcoTEC Plus 424 heat only boiler?

The Vaillant EcoTEC Plus 424 boiler is provided with a parts and labour warranty lasting 5 years.

Vaillant ecoTEC Plus 424 heat only Gas boiler frequently asked questions

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

Suitable for a house or a flat, the Vaillant EcoTEC Plus 424 heat only boiler is worth considering if you want a 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 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 "output" level. Size does not mean its physical dimensions - it means how powerful it is.

The output level of a boiler tells you how much power it has to heat the water coming from your taps and warming up your radiators. The higher the output level, the greater the volume of water it can heat up.

If the output (measured in kilowatts) is too high, you'll pay higher gas bills and your water will be piping hot. Too low and the water coming out of your taps and being fed into your radiators will often be lukewarm.

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 heating engineer would recommend that this Vaillant ecoTEC Plus 424 heat only boiler would be a suitable installation choice for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


What size is the Vaillant EcoTEC Plus 424 boiler?

The measurements of the Vaillant EcoTEC Plus 424 are 600 mm by 375 mm by 320 mm.

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

We recommend that you select a condensing boiler like the Vaillant EcoTEC Plus gas Vaillant EcoTEC Plus 424 for your home if possible because of the environmental benefits and the money you'll save on your gas bills.

Condensing boilers are much more energy-efficient than older, non-condensing models as they capture and recycle the heat still present in the water vapour condensation and flue exhaust gases that your boiler creates when burning gas for reuse.

Is choosing the Vaillant EcoTEC Plus 424 heat only boiler environmentally friendly?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.

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?

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 EcoTEC Plus 424 was awarded an efficiency rating of 94% with a SEDBUK band rating of "A".

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 EcoTEC Plus 424 scores "A".
