The Combination Boiler explained

Combination or Combi boilers are sometimes confused with condensing boilers, they are very different. Combi boilers take cold water straight from the mains and heat it directly, giving a continuous flow of hot water, although the water pressure is generally not as high as it may be with some other boilers.

Combination boilers are cheaper and easier to fit, because of the fact that there aren’t any tanks to fit. However combi boilers are more likely to break down than other types of boilers. The way that combination boilers heat water they are usually more efficient as they do not lose heat from the storage tank, or waste energy reheating water that has gone cold.

Here are the advantages and disadvantages of Combi boilers;

The advantages of combi boilers:

• A Combination boiler is much smaller, so it will fit into small spaces
• Combination boilers are more efficient, making them cheaper to run
• Combi boilers provide instant and unlimited hot water
• A modern Combination boiler produces up to 18litres of water every minute at 35°C

The disadvantages of combi boilers:

• The flow of hot water from the combi boiler can be interrupted if a tap is turned on elsewhere in the house
• The lower volume of water means that because water is heated on demand there will be less available at one time
• The water pressure from a combination boiler is often less than other types of boiler
