Gas And Condensing Combination Boiler Features

It is important to remember that there are several different types of combination boilers. We feel that in order to get an idea of what each of them is like you need to know the features that each of them has. This will help you to know what will work best in your home.


The gas combi boilers are designed with high quality combustion systems that are easy to use and to maintain. Usually these are kept on the top of the unit so that they are easy to replace. This will save you from having to spend thousands of dollars to replace the entire unit.

The design used on the casing will reduce the cost of anything lost and helps to keep the combustion noises down to a minimum. The electric ignition – which is offered on most models – makes lighting it easy.
