5. Condensing boiler
technology based heating systems
| Learning objective
Condensing boilers work in relatively low temperature ranges. The ideal working range for condensing boilers are forerun/reverse running temperatures of 40°C/30°C. So, the temperature spread is 10K.
But also heating systems with temperature ranges of 75°C/60°C or 55°C/40°C use the advantages of condensing boiler technology.
The diagram below shows the temperature curves as a function of the outside temperature for a heating system with 75°C/60°C:
