The invention provides an efficient heating technology and method. The efficient heating technology and method mainly refer to a thermal power plant, a primary water supplying pipe, a primary water returning pipe, a heat exchanger, a secondary water supplying pipe, a secondary water returning pipe, a heat pump unit, a resident heating water returning pipe, residents, a resident heating water supplying pipe, a community heating heat exchange station and the like. Water for heating flowing out from the thermal power plant is usually high-temperature hot water, in the efficient heating technologyand method, the water for heating flowing out from the thermal power plant is low-temperature water which mainly refers to water at the temperature of 35 DEG C or below, the low-temperature hot waterflows out from the thermal power plant and enters the community heating heat exchange station, the temperature of the low-temperature water is increased through the heat exchanger and the heat pump unit, and when the heating temperature is reached, the hot water is directly delivered to the resident users for heating. Through the set of heating system, the utilization efficiency of heating energycan be improved, the comfort quality of heating is improved, pollution emissions of winter heating are lowered, and important energy-saving benefits and social benefits are achieved.
