Combi boilers

The combination boiler is the top choice of homeowners in the UK when they’re looking for a new boiler, and that’s for several reasons. First of all, it’s a great option for a home with a shortage of space.

Best boiler brands 2022 Compare Boiler Quotes

That’s because everything needed is one unit, and the combi boiler simply heats the water on demand.

Now, that can cause some challenges if you have more than one bathroom or need to have hot water delivered to two outlets at the same time. That’s because the combi may struggle to deliver that volume of hot water all at the same time.

However, help is at hand because several boiler manufacturers have come up with a solution for that issue in the form of a storage combi boiler!

If you already have a combi, then it’s highly likely that’s the replacement type that you’re going to be looking

System boilers

For larger homes or where there’s high demand for hot water, then a system boiler might be a good choice.

Best boiler brands 2022 Compare Boiler Quotes

System boilers store the hot water in a hot water cylinder, so that means that they have a large volume of hot water ready to go on-demand. Our system boiler prices guide can help you calculate how much a system boiler will cost you.

System boilers pull their water supply directly from the mains, so there’s no need for a cold water tank. If you currently have a system boiler, the most straightforward option for a new boiler is to go for exactly the same type.

However, if your heating and hot water requirements have changed, there’s no reason why you can’t go for a combi, it will just be a slightly longer installation process.

Regular boilers

Sometimes known as a conventional boiler, the regular boiler is the oldest type of boiler to be found in UK homes.

Both regular and system boilers store hot water ready for use, but the regular boiler also needs a cold water tank that’s usually located up in the loft.

If you do have a regular boiler right now, swapping it for the same is the easiest solution. However, you may find long term efficiency gains and reduced bills by switching over to a combi or regular boiler.

Intergas warranty

The warranty period offered by Intergas depends on the exact boiler model chosen., So for the Eco RF and Xclusive range, for example, the period of cover is ten years while for the Rapid boiler, it drops right down three years.

It is worth knowing though that there is a separate warranty period on the heat exchanger which for the Rapid boiler is seven years.

The top Intergas combi boiler

The Xclusive is the latest addition to this boiler brand. It includes, as standard, the ability to manage your heating remotely and also the functionality to allow your installer access to the system to ensure ongoing high levels of efficiency.

The modulation ratio of 1:9 further increases the efficiency of the Xclusive, and there’s the option for what’s called Priority Hot Water. This briefly switches the boiler to focus on providing hot water rather than heating.

As a result, hot water is supplied much quicker than you would usually expect without any real noticeable impact on the heating temperature.
