Baxi Duo-tec 24 Combi Gas boiler frequently asked questions

What type of boiler is the Baxi Duo-tec 24 - regular, system or combi?

Suitable for a house or a flat, the Baxi Duo-tec 24 combi boiler is worth considering if you want a combi boiler.

Combi boilers provide hot water or heating for your home on demand. You just need to turn the tap to get hot water or switch on the radiator and you’ll feel your home warm up within minutes.

In contrast, traditional boilers required either one or two large storage tanks to work - one to heat and keep water warm and the other to hold cold water for later heating. If the immersion tank was empty, it wasn’t uncommon to wait up to an hour for enough hot water to fill a bath, for example.

Combi boilers draw cold water from the mains and then heat it instantly whenever it's needed, all from one small unit.

The one disadvantage to combi boilers is that, if more than one point is in use at any one time (for example, if someone is taking a shower and another person turns on a hot water tap elsewhere in the property), water pressure, temperature and volume drop to both points.

Is a Baxi Duo-tec 24 combi boiler right for my house or apartment?

To determine that, we need to consider the size of the boiler. However, size doesn't refer to how big a boiler is - it means the size of its "output".

Your boiler’s output is a measurement of the power it has available to heat the volume of water required for your taps and radiators. The higher the output rate, the more water it can heat.

You need to be careful to select a boiler with the optimal level of output for your property though. That's because, if your boiler output is too low, your water and radiators will often not be as hot as you want them to be. If the output is too high, you’ll be paying more for gas than you need to.

The output of the Baxi Duo-tec 24 combi is 24 kW, so which types of property would this Baxi Duo-tec 24 Combi boiler be appropriate for?

Most experienced heating engineers would likely recommend that, at this level of output, this Baxi Duo-tec 24 Combi boiler would be a suitable choice for smaller homes and apartments with up to 10 radiators and one bathroom.

You also need to choose a combi boiler with the right flow rate for where you live.

A combi boiler's flow rate is the maximum volume of water (measured in litres per minute) that it can heat and distribute to your radiators, taps and showers at the same time. This Baxi Duo-tec 24 Combi boiler's flow rate is 10 L/m.

However, combi boilers like the Baxi Duo-tec 24 draw water directly from the mains and heat it instantly.

If your mains pressure is 12 litres per minute, your boiler can only heat and distribute hot water at a rate of 12 litres per minute even if it has a higher flow rate.

Combi boilers also struggle when multiple people in your home want to use hot water at the same time - for example, someone running the hot water tap in the kitchen and two people wanting to shower in separate bathrooms.

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.


Dimensions of the Baxi Duo-tec 24 boiler

The Baxi Duo-tec 24 is 780 mm high by 450 mm wide by 345 mm deep.

Is the Baxi Duo-tec 24 condensing or non-condensing?

We recommend that, if possible, you select one of the very latest condensing gas boilers on the market like the Baxi Duo-tec 24.

Condensing boilers are better for the environment because they capture and recycle the heat still present in flue exhaust gases and water vapour condensation for re-use, meaning lower greenhouse gas emissions.

They're also a lot cheaper to run meaning that, if you're replacing a very old and inefficient boiler, the savings on your gas bill over 5-10 years add up to more than you pay for the boiler itself.

Is the Baxi Duo-tec 24 combi boiler environmentally friendly?

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

As much as 14% of the UK’s greenhouse gas production derives from our domestic central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in Britain's largest cities.

Will choosing a Baxi Duo-tec 24 combi boiler for your home be positive for the environment? Let's examine the figures.

All boilers manufactured in the UK from April 2018 must achieve a SEDBUK “A” grade and an energy efficiency rating of 92% or above. Before that, the minimum was 88% - efficiency ratings of 88% and 89% were scored a “B” and 90%+ an "A".

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

The energy efficiency of the Baxi Duo-tec 24 was rated at 92% with a SEDBUK grading 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 Baxi Duo-tec 24 scores "A" for heat and "A" for water.

If the Baxi Duo-tec 24 breaks down, will I be covered by the warranty?

On the Baxi Duo-tec 24, the manufacturer offers a parts and labour warranty of 7 years.

Baxi Duo-tec 24 Combi Gas boiler frequently asked questions

Is the Baxi Duo-tec 24 boiler a combi, system or regular boiler?

The Baxi Duo-tec 24 boiler could be suitable for your house or flat if you are looking for a new combi boiler.

Traditional boilers have one or more large tanks in which they store either heated water or water to be heated later. Manufacturers originally introduced combi boilers to the market in the 1970s to enable homeowners to save space - UK residential properties are among the smallest in the Western world.

Combi boilers don't need these tanks because they draw water directly from the mains and instantly heat it on demand thanks to the technology inside the boiler. Combi boilers then distribute this hot water to your home’s taps and radiators when needed.

The most significant disadvantage of combi boilers is that they are not ideal in larger homes where multiple people might want hot water at the same time – for example, if someone is having a shower while another wants to wash dishes in the kitchen. This is because combi boilers have a maximum volume of water that they can heat. When two people want hot water at the same time, the water temperature, pressure and volume delivered to both points drop.

Is a Baxi Duo-tec 24 combi boiler suitable for my apartment or house?

Whether this Baxi Duo-tec 24 Combi 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 Baxi Duo-tec 24 combi is 24 kW, so which types of property would this model be appropriate for?

A PlumbProud boiler engineer would recommend that this Baxi Duo-tec 24 Combi boiler is suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

You should also consider a combi boiler's "flow rate" when making your choice.

The flow rate indicates how much water it can take from the mains supply at any one time (measured in litres per minute), which it then heats and distributes to different points in your home like your bathroom, kitchen and radiators. This Baxi Duo-tec 24 Combi boiler's flow rate is 10 L/m.

Combi boilers have no storage tanks like system or heat only boilers. This means that if the water pressure where you live is low, there's no benefit in spending money on a combi with a high flow rate because a high flow rate doesn't mean it can draw any more water from the mains.

In addition, there might be lots of people in your household who want to use hot water at the same time while also having the central heating on. Given that average mains pressure in the UK is between 10 and 12 litres per second and a power shower usually requires about 12 litres of water per minute, a combi boiler might not be the right choice for you and your family.

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.


How big is the Baxi Duo-tec 24?

The Baxi Duo-tec 24 measures 780 mm in height and has a width of 450 mm and a depth of 345 mm.

Is the Baxi Duo-tec 24 condensing or non-condensing?

The Baxi Duo-tec 24 is a condensing gas boiler - we strongly recommend that you choose one of the latest condensing models if possible.

With a condensing boiler, you save money on your gas bills because your boiler captures and recycles the heat present in the flue exhaust gases and water vapour condensation for re-use, meaning they operate far more economically and efficiently.

How energy efficient is the Baxi Duo-tec 24 combi?

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.

As much as 14% of the UK’s greenhouse gas production derives from our domestic central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in Britain's largest cities.

Would choosing a Baxi Duo-tec 24 combi help the environment? Let’s see what the performance figures suggest.

All boilers manufactured in the UK from April 2018 must operate at a minimum level of energy efficiency of 92% ("A" rating on the SEDBUK scale). Before that, the minimum was 88% - boilers scoring 88/89% were given a SEDBUK "B" rating and 90% or above an "A" rating.

The energy efficiency score of a boiler indicates how much energy it uses and how much goes to waste when in use.

After its assessment, the Baxi Duo-tec 24 was given an efficiency rating of 92% and a SEDBUK grading of "A".

The Energy Related Products Directive (ERP) was introduced in 2015 and it applies to all products that consume energy throughout their lifetime, including during the manufacturing process and at the point of final disposal.

The purpose of the ERP is to ensure that companies create products that are kinder to the environment by reducing both the energy they use and the harmful emissions they produce.

The Baxi Duo-tec 24 has an ERP rating of "A" for heat and "A" for hot water production.

Will I be covered if the Baxi Duo-tec 24 combi breaks down?

The Baxi Duo-tec 24 boiler has a warranty covering parts and labour costs for up to 7 years after installation.
