Intergas Rapid 25 Combi Gas boiler frequently asked questions

Intergas Rapid 25 - a combi boiler, system boiler or regular boiler?

The Intergas Rapid 25 is a combi boiler you may wish to consider if you want this particular type of boiler for your house or flat.

Traditionally, boilers needed one or more large tanks installed in your property to store their heated water or water that was to be heated later. These tanks were often too large to be practical for most homes so the combi boiler was introduced to Britain in the 1970s by manufacturers to help homeowners overcome this issue.

Instead of using tanks as storage, a combi boiler heats water on demand. It draws water from the mains and heats it instantly on demand before distributing it to wherever it is needed in a property, be it your taps or radiators.

Unfortunately, combi boilers have one main disadvantage for larger properties or larger households. Because they have a maximum volume of water that can be heated on demand at any given time, water pressure, volume and temperature will drop if, for example, someone is taking a shower and another person in your home wants to use a hot water tap at the same time.

Should I install a Intergas Rapid 25 combi boiler in my home?

Whether this Intergas Rapid 25 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 Rapid 25 combi outputs at a maximum of 25 kW, so which types of property would this Intergas Rapid 25 Combi boiler be appropriate for?

A heating engineer would recommend that the Intergas Rapid 25 combi boiler would be a suitable installation option for 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 Rapid 25 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 Rapid 25 Combi boiler's flow rate is 11 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.


What is the size of the Intergas Rapid 25?

The Intergas Rapid 25 is TBC mm tall, TBC mm wide, and TBC mm deep in size.

Is the Intergas Rapid 25 non-condensing or condensing?

We recommend that you select a condensing boiler like the Intergas Rapid gas Intergas Rapid 25 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 the Intergas Rapid 25 combi a good choice for the environment?

As the British public has become more conscious of climate change, many homeowners consider the environment when choosing how to heat their homes.

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

Will choosing to install a Intergas Rapid 25 combi in your home help the environment? Let's review the figures.

The energy efficiency rating for a boiler describes the amount of energy it uses and wastes during operation and there are two different ways to measure it.

All boilers manufactured and supplied in the UK must have a SEDBUK rating of “A” subject to a minimum energy efficiency score of 92% or above. Before April 2018, the minimum energy efficiency score was 88% (88/89% = "B" SEDBUK rating, 90%+ = "A" SEDBUK rating).

The Intergas Rapid 25 scored an efficiency rating of 93% and a SEDBUK band rating of A.

The Energy Related Products (ERP) directive is Europe-wide legislation designed to reduce harmful gas emissions at all points of a product's life cycle - from the production process to its actual end use, right through to final disposal.

The Intergas Rapid 25 has a rating of "A" for heat and "A" for water.

How long is the warranty period on a Intergas Rapid 25 combi boiler?

Intergas’s Rapid 25 boiler includes a parts and labour warranty of 3 years.

Intergas Rapid 25 Combi Gas boiler frequently asked questions

Is the Intergas Rapid 25 a system boiler, a combi boiler or a regular boiler?

Looking for a gas combi boiler for your house or flat? If you are, the Intergas Rapid 25 boiler may be worth considering.

Traditional boilers often have up to two tanks that either store heated water or water to be heated later. Boiler manufacturers introduced combi boilers in the 1970s to avoid the need for those big tanks. Combi boilers allow homeowners to benefit from the reliable central heating and hot water level they want but without having to give up so much space within their properties - remember that homes in the UK are among the smallest in the developed world.

Your taps and radiators get the hot water they need with a combi boiler. Combi boilers draw cold water direct from the mains which is then heated instantly on demand and distributed to your radiators and taps.

However, combi boilers cannot heat very large volumes of water, which is their main disadvantage. So, for example, when someone wants to take a shower while another person wants to use a hot water tap to do the dishes, water pressure and quantity to both points decreases.

Is a Intergas Rapid 25 combi the right boiler for my house or flat?

Whether this Intergas Rapid 25 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 Rapid 25 combi boiler is 25 kW, so which types of property would this be appropriate for?

A PlumbProud Gas Safe boiler installer would recommend that this Intergas Rapid 25 Combi boiler be installed in smaller homes and apartments with one bathroom and up to 10 radiators.

When choosing a combi boiler like the Intergas Rapid 25, you need to consider the "flow rate" as well as the output rate. Flow rates (measured in litres per minute) indicate the volume of hot water that the boiler can heat up and then distribute to your taps and radiators.

However, combi boilers draw water from the mains and this means they can only heat the amount of water that actually enters your property.

What this means is that, if your mains pressure is 12 litres per minute, that is your boiler's effective flow rate even if it has the capacity to process 18 litres per minute. This Intergas Rapid 25 Combi boiler's flow rate is 11 L/m.

To give you an idea of the flow rate you might need, a power shower typically requires around 12 litres of water per minute and a basin tap requires 4-8 litres per minute.

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 dimensions of the Intergas Rapid 25 are

The Intergas Rapid 25 measures TBC mm tall, TBC mm wide, and TBC mm deep.

Rapid 25 – condensing or non-condensing?

We recommend that you choose a condensing boiler wherever possible like the Intergas Rapid 25 - try to go for the latest model, if possible, to take advantage of improving technology.

Condensing boilers capture and recycle the warmth still present in the water vapour condensation and in flue exhaust emissions created by burning gas to make them more efficient and economical to run.

You will save money on your gas bills too, plus condensing boilers are friendlier to the environment.

Does the Intergas Rapid 25 combi protect the environment?

How we heat our homes is an issue which many homeowners worry about as the world combats climate change and environmental damage.

Gas boilers are responsible for dangerous atmospheric levels of nitrogen dioxide emissions in Britain's biggest cities and, overall, 14% of the UK’s greenhouse gases are produced by our domestic central heating systems.

Would choosing the Intergas Rapid 25 combi be an environmentally-friendly choice? If so, let's look at its performance figures.

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 Intergas Rapid 25 was awarded an efficiency rating of 93% with a SEDBUK band rating of "A".

In 2015, new legislation was introduced by the EU to encourage manufacturers to develop more energy-efficient products that emit fewer harmful gases throughout their lifetime.

The Energy Related Products Directive (ERP) applies to all products that consume energy, including during the manufacturing process, at the point of final disposal, and all points in between.

The ERP rating of the Intergas Rapid 25 is "A" for heat and "A" for hot water.

If the Intergas Rapid 25 breaks down, will I be covered by the warranty?

Intergas’s Rapid 25 boiler includes a parts and labour warranty of 3 years.
