The types of boilers available
Let’s start with an introduction to the different types of boiler that you can choose from:
Combi boilers
Combi, short for combination, boilers have everything you need for heating and instantaneous hot water in one compact appliance. This makes it a good option if you only have one bathroom or have limited space for a hot water cylinder as we’ll look at later.
Heat only boilers
You might have heard about heat only boilers as ‘open vent’ or ‘conventional’ boilers. These typically have a cold water ‘feed and expansion’ storage tank in the loft and a hot water cylinder in the airing cupboard. The boiler is typically sited in a kitchen cupboard and also rely on external components such as an expansion vessel and pump typically sited in an airing cupboard. Heat Only boilers are ideal for larger homes with multiple bathrooms where several taps, showers or baths run simultaneously without losing water pressure.
System boilers
A system boiler contains all the major components of the heating and hot water system, including the pump and expansion vessel, and heats water in a sealed hot water cylinder, usually in an airing cupboard. Again, these are perfect for larger properties with multiples bathrooms.
Electric boilers
Electric boilers are an effective option for properties that are off the mains gas grid network, due to being highly efficient and low maintenance.
Understanding instantaneous or stored water needs
Your hot water needs and demands will be a key part of deciding whether your boiler is the right one for you. If you have high water usage, with multiple bathrooms and a need for consistent pressure, then you might need to consider a system boiler, which heats water stored in a cylinder ready for use. System boilers also provide hot water at a high flow rate without supply to other areas of your property being affected.
On the other hand, a combi boiler provides the convenience of being able to fit in a cupboard or a utility room without needing a separate cylinder for hot water. However, you may find that performance decreases when multiple hot water taps are in use at the same time.
