What is …… condensing technology?

Sooner or later, anyone building a new home or refurbishing an old one has to think about a suitable heating system; a heating system, which is not only energy efficient and environmentally friendly, but also value for money and easy to maintain. When evaluating the many different alternatives and, taking efficiency into consideration, one invariably ends up looking at “condensing technology”.
By comparison
Condensing technology represents the most up-to-date method of heating using one fuel. Compared to low temperature appliances and 25 year old, standard boilers, the efficiency has increased considerably.
The temperature of the heating water is matched to the external temperature and heat demand in much the same way as with low temperature appliances. This saves a considerable amount of energy compared to old heating boilers, which used to keep the temperature of the heating water at a constant 80° C.
Heat exchanger
A great advantage of heating using a condensing system is the utilisation of heat energy from the flue gases. The combustion gases created by the combustion process are fed through the heat exchanger from top to bottom (see image: gas side) and heat up the heating water, which flow from bottom to top (see image: water side). The cold heating water, which has now expended its heat through underfloor heating or radiators, absorbs the heat from the combustion gases. This rapidly cools the combustion gases, which leads to condensation and to heat release; heat, which is again absorbed by the heating water.
‘Noticeable’ efficiency

One really noticeable example of efficiency is the low flue gas temperature at the chimney, which is the result of the utilisation of combustion gas heat. An easier way by far, however, is to look at one’s bank balance - no need to climb onto the roof. High efficiency saves fuel and energy, which in turn saves money.
This system is even more interesting to builders because flue gas ducting, the chimney as it were, can be made up of plastic piping as the flue gas temperatures are so low, which means building costs are reduced.
Further information
If you are interested in condensing systems or any other heating systems, please request the Weishaupt guidebook, which is available free of charge. In it you will find everything you need to know about oil and gas condensing units, solar systems and heat pumps; technology, function and the advantages of individual alternatives.
