Intergas Xtreme 24 Combi Gas boiler frequently asked questions

Is the Intergas Xtreme 24 a combi, system or regular boiler?

The Intergas Xtreme 24 is worthy of consideration if you're looking for a combi boiler for your flat or house.

Combi boilers have much to recommend them - not least the fact that they save a lot of space. Combination (or combi) boilers were introduced by manufacturers in the 1970s to provide practical central heating and hot water distribution to smaller properties - remember that UK houses and flats tend to be among the smallest in the developed world.

Traditional boilers require one or more storage tanks to keep hot water warm and to store water for heating later. In contrast, combi boilers draw water directly from the mains supply and heat it instantly, removing the need for a storage tank. The heated water is then distributed to your taps and radiators on demand.

While combi boilers are suitable choices for many properties, especially those without a loft, there is also a disadvantage in using them. Water is heated instantly and the volume of water that can be heated at any one time is limited. This can result in less water being sent to taps and showers if more than one is being used simultaneously. In these instances, the water pressure to both points will drop.

Should I choose a Intergas Xtreme 24 combi boiler for my house or flat?

Whether this Intergas Xtreme 24 Combi 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.

A boiler’s output is a measurement of the amount of power it can use to provide hot water to your taps and radiators. The higher its output rate, the more water it can heat.

If your new boiler’s output is too low, your hot water might not be as hot as you want it to be. If it's too high, you’ll be paying more for gas than you need to.

The output of the Intergas Xtreme 24 combi boiler is 18 kW, so which types of property would this be appropriate for?

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

Please remember to consider "flow rates" as well when choosing your new boiler. All combi boilers including the Intergas Xtreme 24 draw water from the mains.

Each combi boiler has its own flow rate (measured in litres per minute) - this tells you how much water it can heat and distribute to your home’s taps and radiators straight from the mains. This Intergas Xtreme 24 Combi boiler's flow rate is 15 L/m.

There is no benefit to you in choosing a combi with a high flow rate if your mains pressure is low - save money by buying a boiler whose flow rate is equal to or slightly more than the pressure in your water pipes.

In addition, if you have a lot of radiators and bathrooms in your home or you have a large household that often uses lots of hot water at the same time, like for regular morning and evening showers, a combi boiler may not be suitable.

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.


Making space for the Intergas Xtreme 24

The Intergas Xtreme 24 is TBC mm high by TBC mm wide by TBC mm deep.

Is this Intergas boiler non-condensing or condensing?

The Intergas Xtreme 24 is a condensing gas boiler - we’d strongly recommend that you choose the very latest condensing model for your home.

Condensing boilers run on either gas or oil and are manufactured specifically to improve energy efficiency. They do this by capturing and recycling the warmth present in flue exhaust gases and water vapour condensation into more usable heat the system can use, meaning they're far more efficient and cost less to run.

What energy efficiency ratings have been awarded to the Intergas Xtreme 24 combi?

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.

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.

Do the figures suggest that installing the Intergas Xtreme 24 combi at your property would help in the fight against climate change?

By law, the minimum level of energy efficiency for boilers manufactured in the UK is 92%, equivalent to a good SEDBUK “A” rating. Prior to April 2018, the minimum was 88% - boilers whose energy efficiency levels were 88% or 89% were given a "B" rating on the SEDBUK scale and those at 90% or higher were given an "A".

The energy efficiency rating awarded to each boiler indicates the amount of energy that is wasted when in operation.

Following testing, the Intergas Xtreme 24 was given a 93% energy efficiency rating and a SEDBUK grading of "A".

The ERP (or Energy Related Products Directive) is European legislation which applies to all products that consume energy throughout their lifetime.

Its purpose is to encourage manufacturers to offer products that are kinder to the environment by reducing harmful gas emissions at all stages, from production and end use right through to disposal.

The ERP rating for the Intergas Xtreme 24 is "A" for heat and "A" for water.

How long is the warranty period on the Intergas Xtreme 24 combi boiler?

The Intergas Xtreme 24 boiler comes with a parts and labour warranty of 7 years.

Intergas Xtreme 24 Combi Gas boiler frequently asked questions

Intergas Xtreme 24 - a regular boiler, combi boiler or system boiler?

The Intergas Xtreme 24 is a gas combi boiler.

Traditional boilers require at least one large cylindrical tank to work, normally housed in a large landing cupboard, utility room or the attic. As the UK has some of the world's smallest residential properties, manufacturers introduced the combi boiler in the 1970s to address the issue of space while meeting homeowners' need for central heating and hot water at the same time.

Combi boilers don't need external storage tanks. Instead, they draw water directly from the mains, heat it and then distribute it on demand to the areas where it is needed.

The most important disadvantage of combi boilers is that they have a maximum capacity for the amount of water they can heat up. This means that, if one person in your household is having a shower and another person turns on a hot water tap elsewhere, then the volume, pressure and temperature of the water to both points decreases.

Is a Intergas Xtreme 24 combi boiler suitable for my house or apartment?

Whether this Intergas Xtreme 24 Combi 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 Intergas Xtreme 24 combi outputs at a maximum of 18 kW, so which types of property would this Intergas Xtreme 24 Combi boiler be appropriate for?

A heating engineer would recommend that the Intergas Xtreme 24 combi boiler would be a suitable installation option for smaller homes and apartments with up to 10 radiators and one bathroom.

As well as the output rate, you need to consider "flow rate" when choosing a combi boiler.

The flow rate describes how much water a combi boiler can draw from the mains, instantly heat, and then send to your radiators. Flow rates are measured in litres per second and this Intergas Xtreme 24 Combi boiler's flow rate is 15 L/m.

The water in your mains pipe also has its own flow rate - normally between 10 and 12l/m in most parts of Britain. This means that, if you choose a combi boiler with a flow rate of 17l/m where local water pressure is 11lm, it won't actually process more water because of the slower flow rate of the mains.

In addition, larger households with more than one bathroom, multiple radiators, and where family members may want to use hot water at the same time (like morning showers) may actually need a boiler with a higher flow rate than either the boiler or the local mains pipe.

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.


What are the proportions of a Intergas Xtreme 24 boiler?

The measurements of the Intergas Xtreme 24 are TBC mm by TBC mm by TBC mm.

Intergas Xtreme 24 – condensing or non-condensing?

The Intergas Xtreme 24 is a condensing gas boiler - we’d strongly recommend that you choose the very latest condensing model for your home.

Condensing boilers run on either gas or oil and are manufactured specifically to improve energy efficiency. They do this by capturing and recycling the warmth present in flue exhaust gases and water vapour condensation into more usable heat the system can use, meaning they're far more efficient and cost less to run.

Is the Intergas Xtreme 24 combi considered environmentally friendly?

Price and performance are two important issues when choosing a boiler but now, for many people in the UK, so is the environmental impact of how we heat our homes and its effect on climate change.

14% of the UK’s greenhouse gas production comes from central heating. In the bigger cities, gas boilers in particular are responsible for dangerous levels of nitrogen dioxide emissions.

Will choosing a Intergas Xtreme 24 combi boiler for your home be positive for the environment? Let's examine the figures.

The energy efficiency rating of the Intergas Xtreme 24 is 93% 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).

The ERP (or Energy Related Products Directive) is European legislation which applies to all products that consume energy throughout their lifetime.

Its purpose is to encourage manufacturers to offer products that are kinder to the environment by reducing harmful gas emissions at all stages, from production and end use right through to disposal.

The ERP rating for the Intergas Xtreme 24 is "A" for heat and "A" for water.

Does a Intergas Xtreme 24 combi boiler come with a warranty period?

The Intergas Xtreme 24 is supplied with a parts and labour warranty of 7 years.
