| Problem: The north side heats up slowly as a result of which the system setting is adjusted. However, some rooms remain cold. The cause of this is an air bubble which is stopping the flow around the system
Consequence: The efficiency of the central heating system drops by 10%. This equates to 560 m3 of gas per annum, an increase of just under € 252.00.
Solution: Electric heating generating 2000 watts helps but consumes 5 kWh per day. Based on 100 fuel days, this will cost € 110.00. A deaerator is far more efficient and will often pay for itself in less than a year.
