Vaillant ecoTEC Pro 24 Combi Gas boiler frequently asked questions

Vaillant EcoTEC Pro 24 - a regular, combi or system boiler?

You may wish to consider installing the Vaillant EcoTEC Pro 24 if you are looking for a combi boiler for your house or flat.

Boilers traditionally required the installation of one or more large tanks around your property. These were filled with water that was either being heated or was to be heated later. British homes are among the smallest in the world so, to solve the space problem, manufacturers introduced combi boilers in the 1970s to offer homeowners the warmth and hot water supply they needed while taking up much less space.

A combi boiler is designed to heat both radiators and taps on demand and at the same time. Water from the mains passes through a combi boiler and the boiler's technology instantly turns it into hot water. Your boiler then distributes the hot water throughout your home.

The main disadvantage of combi boilers is that they have a maximum water volume capacity. What this means is that, if one person is using the shower while another uses a hot tap simultaneously, less water gets to each area, resulting in a fall in water pressure at both points.

Would the Vaillant EcoTEC Pro 24 combi boiler be suitable for my house or flat?

It's best to choose a boiler whose size or "output" is right for your property. With boilers, however, size does not mean how big a boiler is, it means how much power it has.

A boiler’s output indicates the amount of power it can use when heating the water which it then sends to your taps and radiators. The higher the output rate, the more water it can heat.

If a boiler’s output is too low, there will be times when your hot water might not be as hot as you want it to be. If it is too high, you’ll likely be paying more than you need to for your gas.

Measured in kilowatts, the Vaillant EcoTEC Pro 24 combi's output level is 23.4 kW, so which types of property would this Vaillant ecoTEC Pro 24 Combi boiler be an appropriate choice for?

A boiler engineer would recommend that, at this level of output, the most suitable type of property for this Vaillant ecoTEC Pro 24 Combi boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.

With combi boilers like the Vaillant EcoTEC Pro 24, you need to take the flow rate into account as well as the output rate.

Combi boilers draw water from the mains and then instantly heat that water and send it to wherever in your home it's needed. Flow rates, measured in litres per minute, are subject to the mains water pressure in your area. So, for example, if the local mains water pressure is 11 litres per minute and the flow rate of your boiler is 14 litres per minute, the boiler will not be able to process more than 11 litres per minute. The flow rate of this Vaillant ecoTEC Pro 24 Combi boiler is 10 L/m.

If you live in a home with lots of radiators or bathrooms where many people want to use hot water at the same time, a combi boiler may not be able to cope. For reference, a power shower uses about 10 litres of water per minute. If two people want showers at the same time or one person wants a shower and the other hot water from a tap in the kitchen, your boiler may not have a large enough flow rate even if the local mains water pressure is high.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


Vaillant EcoTEC Pro 24 dimensions

The dimensions of the Vaillant EcoTEC Pro 24 are 720 mm [H] x 440 mm [W] x 338 mm [D].

Is the Vaillant EcoTEC Pro 24 condensing or non-condensing?

Condensing gas boilers like the Vaillant EcoTEC Pro 24 are environmentally friendlier and cheaper to run so, if possible, we strongly recommend that you choose this or one of the very latest models.

Condensing boilers are much more efficient and economical to run because they contain a secondary heat exchanger that captures and recycles the warmth still present in the flue exhaust gases and the water vapour condensation for re-use, meaning that they use less gas to run.

How environmentally friendly is the Vaillant EcoTEC Pro 24 combi?

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.

The heating of our homes accounts for 14% of the UK's greenhouse gas emissions. Especially in the big cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Is the Vaillant EcoTEC Pro 24 combi boiler an environmentally friendly choice for your home? Here’s what the figures say.

The Vaillant EcoTEC Pro 24 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.

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 EcoTEC Pro 24, the ERP Heat rating is "A" and the ERP Water rating is "A".

How long am I covered by the warranty for if the Vaillant EcoTEC Pro 24 breaks down?

The parts and labour warranty on the Vaillant EcoTEC Pro 24 covers all repair-related costs for 2 years while the heat exchange warranty covers you for [Heat Exchange Warranty] years.

Vaillant ecoTEC Pro 24 Combi Gas boiler frequently asked questions

Is the Vaillant EcoTEC Pro 24 a combi, system or regular boiler?

The Vaillant EcoTEC Pro 24 is a combi boiler you may wish to consider if you want this type of boiler for your house or flat.

Traditional boilers have one or two tanks - one holds hot water to keep it warm and the other water for later heating. Because UK residential property is among some of the smallest in the world, manufacturers introduced combi boilers and the heat pumps that go in them in the 1970s to reduce the amount of space boilers needed to take up.

The hot water needed for your radiators and taps is available on demand when you have a combi boiler. Combi boilers use technology located within the boiler to heat cold water, which it draws from the mains, and to distribute hot water where it's needed around your home.

A combi boiler, however, has the disadvantage of a maximum capacity for the amount of water it can heat. The result is that if someone uses the shower while another uses a hot water tap simultaneously, the amount of water reaching each point falls, causing water pressure to drop.

Is the Vaillant EcoTEC Pro 24 combi boiler suitable 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 Pro 24 combi boiler has an output of 23.4 kW, so which types of property would it be most appropriate for?

To most experienced Gas Safe engineers, the Vaillant EcoTEC Pro 24 combi EcoTEC Pro would be most suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

You'll also need to be sure to choose a combi boiler with the right flow rate for your home.

The flow rate indicates the maximum volume of hot water (measured in litres per minute) that your boiler can distribute at any given time. This means that if you and your family are likely to be using several taps and showers simultaneously or you have a lot of radiators, you need a boiler with a high flow rate. This Vaillant ecoTEC Pro 24 Combi boiler's flow rate is 10 L/m.

As with all combi boilers, the Vaillant EcoTEC Pro 24 is only able to heat and distribute water at the rate at which it actually enters your property.

For this reason, you shouldn't purchase a boiler with a very high flow rate if the flow rate in your mains pipes is lower because the extra capacity doesn't mean it can draw more water from the mains pipes.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


The size of the Vaillant EcoTEC Pro 24

The dimensions of the Vaillant EcoTEC Pro 24 are 720 mm tall, 440 mm wide, and 338 mm deep.

Is the Vaillant EcoTEC Pro 24 condensing or non-condensing?

The Vaillant EcoTEC Pro 24 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 Pro 24 combi boiler an environmentally friendly choice?

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.

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.

Would choosing a Vaillant EcoTEC Pro 24 combi help the environment? Let’s see what the performance figures suggest.

Boilers manufactured or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to this, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The Vaillant EcoTEC Pro 24 has been given a rating of 94% for energy efficiency, equivalent to a SEDBUK "A" rating.

The ERP (Energy Related Products Directive) applies to all products that consume energy at any time in their lifetime, from manufacture to disposal and all points in between.

This European legislation intends to encourage manufacturers to offer end users products that are better for the environment through the creation of fewer harmful gas emissions at all points of a product's life cycle.

The ERP rating for the Vaillant EcoTEC Pro 24 is "A" for heat and "A" for water.

What warranty do I get if I purchase the Vaillant EcoTEC Pro 24 boiler?

The Vaillant EcoTEC Pro 24 boiler comes with a 2 year warranty for parts and labour.
