	*CHECK IT*
	HEATING SYSTEM
1	Pay attention to the reverse running temperature - maximally 60°C.
	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.
2	Speed/revolution adjusted pumps are recommendable.
3	Pay attention to the heating areas - in case of new buildings maximally 75/60°C.
4	No increase of the reverse running temperature.
4	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.
