We have an old central heating boiler of 1998 GT200 De Dietrich. If there is no warmth command, the boiler will heat after every 2 hours, which is waste since there is no demand for heating. However, I did some research and found that the boiler will heat from time to time to make sure the water in the central warming pipes stays at temperature. I also noticed that this 'function' can be turned off but I am not sure if that's also the case with these old models.
