METHOD FOR CONSTANT LOVE THE MAXIMUM AND / OR MINIMUM CAPITAL a water heater.

摘要

Method for keeping constant the maximum and / or minimum power of a water heater, which is provided with a gas burner (2), with a pneumtische gas-air composition control, where it passes through a temperature controller (12) pre-given nominal power is adjusted by an air volume flow, which is generated by a fan motor (4) with adjustable speed. To fluctuations in the nominal capacity to contain the device is ensured according to the invention, the maximum, respectively denomination nmax respectively nmin speed is maintained by a pressure f (Pmax-Pact) f respectively (Pmin-Pact) of the gas-air mixture (5).
