During operation of a regular boiler the hot exhaust gases are given to the atmosphere. However, addition of a second heat exchanger makes it possible to gain the heat in the exhaust gas which is around 150o – 200o C. In the heat exchanger added the waste gas transfers its heat to the cooler water, and the water vapour that the gas contains is condensed and used in the heating system. This operation is what the condensing boilers take their names from. The water vapour in the waste gas contains 8% of the total fuel energy and re-gaining this amount means you gain 8% more energy than a regular boiler from each unit of fuel.

rnThe only thing standing in the way of condensing boilers is that people still don’t know enough about them. Most of the things people think about condensing boilers are not correct.
  • The main concern about them is their prices. The fact that they were once more expensive than traditional boilers is not true anymore. Like all developing technologies, their prices are decreasing and becoming comparable with the regular boilers. In addition to this, when the gain in fuel is considered, this makes them more economical than regular boilers. You can save up to 30% of your fuel costs and in a time as short as 2-3 years they will pay the money you spent on them.
  • They are not more difficult to install than regular boilers. There is only a single unit which is different from regular boilers and an expert installer would install it with no problems.
  • They are as reliable as regular boilers and they do not need any extra maintenance.
  • They can even be used together with solar heating systems or underground heating systems which lets you save further for your energy expenses.
  • They can be connected to your existing heating system. No matter which fuel source you use there is a boiler type available for you, gas or oil.
All you need to do is to calculate your savings and contact us for our condensing boiler products to choose one of them.
