As their name suggests, combi (short for combination) boilers act as both water heaters and a central heating boiler while cutting out the need for additional water storage systems. This means for many, who live in flats or smaller houses, they are the perfect fit for their needs as they are simple and offer an effective way of heating households. Combi boilers heat water directly from the mains when you switch on any hot tap in your system. This is because they have two independent heat exchangers - one for your radiators and one for your hot water supply. 

There are many benefits to having a combi boiler, such as:

• Being economical and energy efficient. Water in your home is heated instantly meaning you can have a hot bath without having to pre-heat the water 

• Their size means they are perfect for smaller homes which may not have any loft space for the additional water tanks that many other boilers require. 

• They are cheaper to install, requiring less pipework to get the hot water around your home

• They are easier to install and maintain. As they are so common, most boiler engineers are now trained to repair them and maintain them.
