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.
