Proposed scheme of individual heating unit (IHU) contains a mixing device based on energy-efficient two-flow membrane pump operating in pulse mode at available head of the heating network. The problem was solved of finding the optimal regimes of membrane pump work, which provided qualitative and economical efficacy of heating devices. Experimental graphs illustrate the pressure changes in the working chambers of the pump equipped with a pulse heating medium flow distributor. It is shown that implementation of the membrane pump in the IHU circuit allows distributing temperature more evenly throughout the heating devices surface due to pulsating mode of the heating media movement.
