In a method of setting the mean value of the supply temperature (T V) of a heating medium which is intermittently heated by a heating apparatus (5) in a heating system comprising at least one adjustable throttling point (16, 17, 18) for the heating medium a desired supply, temperature value (T S) is determined on the basis of external influencing factors (H, T external) and the heating medium is heated to the desired supply temperature value (T S) with the throttling points (16 17, 18) fully open. The mean value of the supply temperature is to be controlled to such a value that an optimum total throughflow rate of the heating medium is achieved, i.e. the throttling points formed by …

Why it's free to use
- Filed October 17, 1989 and granted January 12, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 17, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 17, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
