Intergas Xtreme 24 Combi Gas boiler frequently asked questions

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

Looking for a gas combi boiler for your flat or house? Then the Intergas Xtreme 24 may be an option you should consider.

Traditionally, most boilers required you to find space in your property for one or more large storage tanks. These tanks would either keep water warm or hold it in reserve for later heating. Manufacturers originally introduced combi boilers to offer homeowners the same level of warmth and hot water without taking up as much space – remember that the UK has some of the smallest homes in the Western world.

With a combi boiler, the hot water needed for your radiators and taps is provided on demand. Water from the mains passes through your combi boiler and the technology within it instantly heats the cold water. It then distributes that hot water around your home.

The biggest drawback for combi boilers is that they have a maximum capacity in volume for heating water. This means that if someone wants to use the shower while another person wants to use a hot water tap, the amount of water reaching each point falls, resulting in a drop in water pressure.

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, however - it means how powerful it is.

Measured in kilowatts, a boiler's output level is an indication of the amount of power it has available to it to heat the water coming from your taps and for warming your radiators. The greater the output level, the more water it can heat.

If you choose a boiler whose output level is too low, you'll often find that the water is not as hot as you want it to be. If you choose a boiler whose level is too high, you'll be paying higher gas bills than you need to for years to come.

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

An experienced PlumbProud heating engineer would recommend that the level of output from this Intergas Xtreme 24 Combi boiler would make it a suitable installation option 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 Intergas Xtreme 24 Combi boiler's flow rate is 15 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.


What are the proportions of a Intergas Xtreme 24 boiler?

The Intergas Xtreme 24 is TBC mm tall, TBC mm wide, and TBC mm deep.

Intergas Xtreme 24 – condensing or non-condensing?

We strongly recommend that you choose a condensing boiler like the Intergas Xtreme 24 - the technology is improving every year so the newer the boiler, the better.

A condensing boiler captures and recycles the warmth still present in flue exhaust gases and water vapour condensation into heat, allowing it to perform more efficiently on tasks like heating the colder water returning from your radiators.

They also offer significant annual savings on household gas bills as well as being more environmentally friendly.

How does the Intergas Xtreme 24 combi boiler rate environmentally?

As more of us are increasingly concerned about climate change, how we heat our homes and its impact on the environment has become an issue of importance to homeowners.

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

Would choosing a Intergas Xtreme 24 combi help the environment? Let’s see what the performance figures suggest.

All boilers manufactured and installed in the UK are required by law to have an energy efficiency rating of at least 92%, equivalent to a good “A” rating on the SEDBUK scale. Before this, the minimum was 88% (ratings of 88% and 89% are equivalent to a high “B” SEDBUK rating and anything 90% or higher is an "A" rating).

A boiler's energy efficiency rating is designed to let you know how much energy is used and wasted during normal functioning.

The Intergas Xtreme 24 was given an efficiency rating of 93% and a band rating of "A".

The Energy Related Products Directive (ERP) came into force in 2015. This legislation was introduced to encourage manufacturers to create more energy-efficient products and it covers all products that consume energy during their lifetimes, including energy used during production and at the point of disposal.

ERP ratings of "A" for heat and "A" for water were assigned when testing the Intergas Xtreme 24.

What is the length of the warranty on the Intergas Xtreme 24?

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

Intergas Xtreme 24 Combi Gas boiler frequently asked questions

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

You might want to consider the Intergas Xtreme 24 for your house or flat if you are looking for a combi boiler.

Combination or combi boilers are highly efficient and save a lot of space in your home. Combi boilers heat water directly from the mains when you turn on a tap and, as a result, you don’t need a hot water storage cylinder or a cold water tank in the roof space.

These boilers are, therefore, suitable for smaller homes and especially those without a loft. They are also cost-effective as the water is heated instantly and distributed on demand rather than being stored. Combi boilers are the most popular type of boilers in the UK and replacing an older boiler with a new combi boiler will reduce your gas bills significantly.

However, there are downsides to this type of boiler. If you take a shower while someone else is using a tap, less water will reach each point of usage at lower rates of pressure and temperatures as combi boilers can only heat a certain volume of water at any given time.

Is the Intergas Xtreme 24 combi suitable for my house or flat?

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".

Your boiler should be able to cope with peak hot water demand in your property and not just your average hot water usage. The output rate of a boiler is measured in kilowatts and tells you how much power a boiler can use to provide hot water to your taps, showers and radiators.

If the output of your boiler is too low, there will often be times when your water isn't as hot as you want. But if your boiler output is too high, it will be more costly to run (often unnecessarily).

The output of the Intergas Xtreme 24 combi boiler is 18 kW kilowatts. Which types of property would this be appropriate for?

A Gas Safe boiler installer would recommend that this Intergas Xtreme 24 Combi boiler would provide adequate heating and hot water for smaller homes and apartments with up to up to 10 radiators and one bathroom.

With combi boilers like the Intergas Xtreme 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 Intergas Xtreme 24 Combi boiler is 15 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.


The size of the Intergas Xtreme 24 in millimetres

The Intergas Xtreme 24 is TBC mm in height, TBC mm in width and TBC mm in depth.

Is the Intergas Xtreme 24 a condensing or non-condensing boiler?

Condensing boilers convert the warmth present in flue exhaust gases and water vapour condensation into heat which they then recycle to increase the temperature of the colder water returning to your system.

We recommend that homeowners choose a condensing boiler like the Intergas Xtreme 24 for this reason - the more recent your model the better because the technology improves every year.

You'll benefit from lower quarterly gas bills and condensing boilers are also much more environmentally friendly.

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

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about climate change.

Approximately 14% of the UK's greenhouse gas production is caused by our central heating systems. The gas boilers in larger urban areas of Britain are mainly responsible for emissions of toxic nitrogen dioxide.

Would choosing a Intergas Xtreme 24 combi help the environment? Let’s see what the performance figures suggest.

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 (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 Intergas Xtreme 24 is "A" for heat and "A" for water.

What length of warranty does the Intergas Xtreme 24 come with?

The Intergas Xtreme 24 boiler comes with a 7 year warranty for parts and labour.
