Pros And Cons Of Combi Boiler Systems

A boiler is an important thing to have when trying to provide hot water and heating to your business or home. You need to find a residential or commercial boiler that is able to run efficiently without costing you a great deal of money. There are a number of different types that it can make choosing just one a bit difficult.

One of the more popular types are the combi boilers. It is important to consider the different pros and cons of this unit to better understand how it can help and whether or not it is worth the money.

How It Functions

Combi boilers will pull the water supply straight from the main supply in the area. This keeps you from having to have a boiler with a hot and cold water tank. With only water tank you will save on the amount of space that you need, use less piping, and spend less in the price you pay to have it installed.


The cost of a combi boiler is a great deal less than that of a standard boiler. This is because it is smaller and is made up of less parts. Most people will automatically assume that because it is smaller it is not as effective. This is a common misconception. Many businesses will purchase an industrial combi boiler because it works quicker and is able to perform two jobs at one time. Not only is the initial cost more affordable – but you will also save money on the fuel or electricity bills.


People who live in small homes, apartments, or who have a small work space are better off using this unit. Their limited space will make it easy for them to pick out the right model and to pay for the installation without going over their budget. The downside to this is that it is not something that you would use in large office buildings or homes.

Homes that have more than one bathroom would be better off using the standard boiler. Combi boilers are not able to heat larger homes. People who try will put their boiler at risk to hard water and system failure.
