A Guide to Combi Boilers 

Is a combi boiler right for you?

Combi boilers, as fantastic, however, are not suitable for every house. So you should think about a system or conventional boiler if:

- There are multiple bathrooms in your house.  

- The main pressure is insufficient.  

Because a combination boiler draws water from the mains, and if it has to provide many outlets simultaneously, it reduces the flow, making it weaker. The flow from the mains helps determine the pressure of the water.

How do combi boilers work?

Combi boilers work by heating water from the mains to heat your house and provide hot water. It delivers the hot water directly to your taps, baths, and showers as required. In contrast, systems and conventional boilers store hot water in a cylinder, helping meet the increased demand for hot water.
