4. Condensing boiler technology checklist

 

 
CHECK IT
 
HEATING SYSTEM
 
1
  • Pay attention to the reverse running temperature - maximally 60C.
  • Adapt the heating curve.
  • Plan the possible installation of a reverse running temperature limiter.
2
  • Try to achieve a temperature spread between forerun and reverse running temperature of at least 15 Kelvin in the case of old installations.
  • Speed/revolution adjusted pumps are recommendable.
3
  • Pay attention to the heating areas - in case of new buildings maximally 75/60C.
4
  • No increase of the reverse running temperature.
  • Do not use mixers and bypass circuits.
 
REGULATION AND CONTROL
 
5
  • The regulation and control of the systems has to be realised according to the new regulations for heating systems.
 
WATER HEATING
 
6
  • The dimension/size of the hot water storage tank has to be planned according to the daily water needs of the hot water consumers.
  • Chose preferably hot water storage tanks with large heat exchanger areas.
  • Plan the time/automatic switch controlled loading (maximally two times per day).
 
INSTALLATION SPACE
 
7
  • The are no special requirements for condensing boilers.
  • The installation of boilers that use room air and that do not use room air has to be discussed with the chimney sweep.
  • Examine the possibility of a roof installation.
