If you’re still scratching your head over which boiler will suit your home, we’re here to help. In this guide, we’ll be focusing on combination boilers (also known as combis). As well as combi boilers, there are a number of boiler types including regular (also known as heat only or conventional) and system, which are suitable for certain types of homes with different layouts. A combi boiler, however, is more suited to small to medium-sized properties, while providing hot water for your central heating and shower/bath time.
Choosing the right boiler is essential to guarantee the correct flow of hot water through your home’s taps and showers, and to ensure your energy bills remain level. The wrong boiler type could lead to long delays for hot water and high energy bills.
Combi boilers have different flow rates, central heating outputs, and hot water outputs. As a rule of thumb, the higher the flow rate, the more likely you’ll be able to run a bath without any issues. Otherwise, most combi boilers will offer enough hot water for a shower and the usual taps installed in your property for up to two bathrooms and 3 bedrooms.
There are a couple of ways to tell if a combi boiler is right for your home. The first and most obvious way to tell is the current layout of your central heating system. If your home only has a boiler installed but doesn’t have a loft tank and hot water cylinder installed, your current boiler is a combination boiler. For an engineer, this tends to be the easiest boiler replacement as it’s just a simple swap between boilers.
If you have a cylinder or tank installed, but experience reduced water pressure when using your shower or running taps, it’s possible that your mains pressure is insufficient for a combination boiler to be installed.
