Intergas Rapid Plus Combi Boiler

Intergas Rapid Plus Combi

The Intergas Rapid Plus Combi is designed for most households and domestic applications.

Intergas says that the Rapid Plus Combi is ‘smart in every sense’ and retains all the benefits of its revolutionary condensing boiler technology. It comes in two power outputs and contains few moving parts to deliver more reliability and to ensure less can go wrong. The boiler is ErP compliant and has some impressive energy-saving features, so not only is it friendly to the environment but it’s also kind to your wallet.

How Much Does this Boiler Cost?

It depends on whether you need the 25kW or 32kW model for your home but we can tell you that the higher output will be a little more expensive than the lower one. The typical price including VAT is between £710 and £790, however, you also need to pay a Gas Safe registered engineer to fit the boiler. Installation prices vary from £500 to £1,500 dependant on the amount of work your engineer has to do to install the Intergas Rapid Plus Combi. If you want to compare prices to find the best deal, you should get a fixed-price quote from a range of local and national installers.

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

The Intergas Rapid Plus Combi heats water directly from the mains as and when you require it and eliminates the need for tanks in the loft and a hot water cylinder in the airing cupboard, making the boiler a great choice if you don’t have a lot of storage space. As combi boilers sometimes can’t cope with high hot water demand, this boiler is best suited to small to medium-sized homes with just one bathroom.

When it comes to choosing the right size combi boiler, it’s best to talk to your heating engineer as they can recommend the best power output for your home and requirements. 

Is it a High Efficiency Boiler?

Yes. The intergas Rapid Plus Combi is ErP compliant and an A-rated boiler in both heating and hot water modes. It features condensing boiler technology to enable the boiler to condense 100% of the time and has a unique two-in-one heat exchanger to reduce heat loss and deliver optimum heat transfer, which means this boiler is ultra-efficient and can help to save you money on your gas bills.

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

It has a built-in digital clock, high-efficiency pump, mirrored sight glass, a fixing bracket, built-in expansion vessel and a central flue with lengths up to 13 metres. The boiler has just four moving parts to minimise the risk of component failure and it comes complete with a two-in-one heat exchanger with a 7-year warranty. What’s more, the Intergas Rapid Plus Combi can be converted to LPG or easily converted into a system or heat only boiler by changing the settings in the software.

How long is the Warranty on this Boiler?

If you purchase the Intergas Rapid Plus, you’ll have peace of mind that your boiler has a 6-year warranty and the heat exchanger has a 7-year warranty.
