Intergas Rapid Combi

The Intergas Rapid Combi comes in two heat outputs to satisfy the demands of most households.

The Intergas Rapid Combi is a reliable condensing gas boiler that combines high-efficiency in both heating and hot water modes. It’s available in two power outputs and can easily be converted to a heat only or sealed system thanks to its state-of-the-art control system. This boiler also has an affordable price tag and is designed to reduce your carbon footprint and your running costs, helping you to save money on your energy bills.

How Much Does this Boiler Cost?

This high-efficiency combi boiler will set you back anything between £630 and £670, including VAT and dependant on whether you need the 25kW or 32kW model. The cost of the installation can vary from £500 to £1,500 depending on how much work is required and you must make sure the boiler is fitted by a Gas Safe registered engineer. We suggest you get a fixed-price quote from at least a few installers so that you can compare prices and find the best deal on the Intergas Rapid Combi and the installation.

How will I know if this Boiler is Suitable for My Home?

Combi boilers, such as the Intergas Rapid Combi, heat water from the mains on demand and don’t require bulky tanks in the loft or a separate hot water cylinder. As this boiler is compact and can deliver heating and hot water without needing any additional components, it’s ideal for homes where space is limited and small to medium-sized properties that have one bathroom.

The Intergas Rapid Combi can be purchased with an output of 25kW or 32kW and you must figure out which size boiler best fits your needs. To ensure you get it right, ask your heating engineer to help you choose the correct size boiler to achieve your heating and hot water requirements.

Is it a High Efficiency Boiler?

Yep. The Intergas Rapid Combi is A-rated for efficiency and features a unique two-in-one heat exchanger, which is designed to reduce heat loss and deliver the optimum heat transfer to ensure economic performance. As the boiler condenses in both heating and hot water modes, it will help to save you some money on your energy bills.

Does this Boiler have a Good Range of Controls and Features?

The boiler has mirrored sight glass, a built-in digital clock, a built-in expansion vessel, a central flue with lengths up to 13 metres and a two-in-one heat exchanger with a 7-year warranty. All of the parts that are contained within the boiler are easily accessible from the front, making it easy for your engineer to service and maintain the boiler. This combi can be converted to a sealed system or heat only boiler and there are LPG options available as well.
