Boiler Types Explained

Are you considering a new boiler but no idea where to start? We understand that different boiler types can be confusing and it’s not always clear what the differences are, so we’ve written an overview of the different boiler types to help you understand.

Combination boilers

These are also known as ‘combi’ boilers and they work by heating the water up directly from the mains which means that hot water is near enough instant when it comes out of your tap. Since they work directly from the mains they don’t require a water storage tank or hot water cylinder making them ideal boiler solutions for flats or small houses where space is limited. If you have good mains water pressure which most homes will, the water pressure in your home will be the same as it is coming directly from the street but be aware that if multiple taps and showers are on at once it can falter. Combi boilers tend to be more energy efficient as they are only heating up water as and when it’s needed rather than heating a whole tank, like how other boilers work which we’ll explain next.

Conventional boilers

Often referred to as ‘traditional’ boilers, these are often found in older homes that may not be able to cope with high water pressure. They are connected to separate water storage tanks and a hot water cylinder which are usually placed in the loft. If you have more than one bathroom in your home a conventional boiler could be a good solution as multiple hot water taps can be running without the temperature being affected. One potential problem with these boilers is that as they use a hot water tank, if that tank is emptied it can take a while to refill.

System Boilers

These are in many ways quite similar to conventional boilers as they also use a hot water cylinder but they don’t need a hot water tank so can save on space. This makes them suitable for most houses, especially if you have multiple occupants as they can provide a constant flow of hot water.
