Ideal Independent Combi Boiler

The Ideal Independent Combi is a modern gas-condensing combination boiler that is perfect for homes where storage space is tight.

Featuring state-of-the-art technology, the Independent Combi by Ideal is a compact cupboard fit boiler that can be installed almost anywhere you want. It’s best suited to flats and small to medium sized-homes that lack space, but a large model is available for larger properties in need of a modern combi boiler. If you don’t currently use a hot water cylinder or cold water tank with your existing boiler, this high-quality unit could be a fantastic option for your home.

How Much Does this Boiler Cost?

The Ideal Independent Combi is a great value for money boiler that costs between £625 and £750. It comes in three heat outputs of 24kW, 30kW and 35kW, and prices vary according to these output sizes so it really depends on which model is recommended for your home. Don’t forget, you’ll also need to consider the fitting cost. If you want to pay the best price for the boiler and installation, you should take some time to shop around and compare prices from different sources.

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

The first thing you need to do is determine if this is the right type of boiler for your home, so you won’t know for sure without seeking advice from a Gas Safe registered engineer. If you already have a combi boiler, then the chances are the Independent Combi will be a suitable option. Nevertheless, it’s still wise to consult a trusted engineer because they will also help you to select the correct boiler size (output) for your needs.

Combi boilers don’t require a separate cylinder that stores hot water or a cold water tank in your loft space. Because they don’t need components such as these, combi boilers are a popular solution for flats and houses where space is an issue. Although combi boilers can provide hot water on demand, they can struggle to produce hot water for multiple taps that are being used at one time, so they’re not really ideal for properties with more than one bathroom.

Is it a High Efficiency Boiler?

It certainly is. This boiler is SEDBUK A-rated, meaning it can provide efficient heating and hot water. By being so efficient, the Ideal Independent Combi should help to reduce your fuel bills and carbon emissions. You can even improve the boiler’s efficiency levels by opting for one of Ideal’s optional controls or accessories, such as a weather compensation kit or an electronic thermostat.

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

Ideal’s Independent Combi comes with a digital display and a range of user controls that enable you to manage the system and control your heating and hot water. It includes its own built-in mechanical timer, allowing you to choose when you’d like the heating to come on and switch off ahead of time. The boiler even has a preheat function to ensure you have immediate access to hot water, no matter the time of day or night. Frost protection has been added as well so that the boiler doesn’t run into trouble when winter weather strikes.

How long is the Warranty on this Boiler?

You’ll get a 5-year parts and labour warranty as standard when you purchase the Ideal Independent Combi, but you must register the boiler within 30 days of installation and have it serviced annually by a Gas Safe registered engineer.

Pros and Cons

We would usually say that a 5-year warranty isn’t bad, but Ideal offers a much longer warranty period than this (sometimes double or more) on some of its other combi boilers. When it comes to the boiler itself, we don’t have anything negative to say because we think it’s an excellent little unit for the money. Below, you can find all the pros and cons (in our opinion) of the Ideal Independent Combi.
