While most purchase them as per the advice of the engineers, they do not quite have ample information about these boilers. This article will present the information that one needs to know before buying such boilers.

What is a Combi Boiler?

As the name suggests, a combi boiler combines a central heating boiler and a water heater in a neat, single unit. Combi boilers are condensing boilers, and the waste gases produced by the heating process generate more heat. The boilers are compact, cause minimum impact to the environment, and save up a lot of space. No wonder they are the most efficient option, so they are finding increasing application in homes today. Since water in a combi boiler heats up immediately, it is a much more efficient option than an immersion heater.

How does a Combi Boiler work?

The water directly heats up from the mains. When the hot water tap turns on, the combi boiler detects the need for hot water. The gas burner turns on immediately, and a heat exchanger system transfers the heat energy to the water. It is how the water heats up in an instant. Under pressure from the mains, the water flows naturally without the need for a pump. 

Modern boilers also have a built-in pre-heat system. It is a small reservoir of water present at a certain temperature, which ensures instant access to hot water whenever you switch on the tap.

Is Combi Boiler my right purchase?  

Combi boilers have limited flow. While it is ideal for the average household with small flats with one bathroom, it is not the right choice for a large property with many bathrooms. Water pressure is another factor that demands consideration before buying a combi boiler since the boilers don’t function to their full potential under low mains water pressure. The size of the boiler (in Kilowatts) is determined depending on the size of the property.
