A hydronic heating system employing comprises a water line, two or more boilers, and a control. In operation, the water line facilitates a circulation of water through a building and the boilers heat the water as the water flows through the water line. The control calculates a system energy load for operating boilers. The calculation of the system energy load is a function of a set-point water temperature for the hydronic heating system, a supply water temperature of water flowing relative to a supply point of the water line, a return water temperature of water flowing relative to return point of the water line and a flow rate of water flowing relative to a flow sense point of the water line.

A heat exchanger usable with a ventilator, the heat exchanger having an improved structure so that air passing through the heat exchanger may be prevented from leaking. The heat exchanger of the general inventive concept includes a heat-exchanging element having a plurality of liners stacked in a uniformly spaced state and a plurality of spacers disposed between the liners to define air passages, and corner guides respectively coupled to corners of the heat-exchanging element. Each of the corner guides includes a guide channel forming a space to receive the corner of the heat-exchanging element so that the corner guides securely come into close contact with the heat-exchanging element, and to minimize a loosening of the corner guide due to an adhesive applied between the heat-exchanging element and the corner guide.

The present invention relates to a powerless hot water pumping apparatus which receives cold water through a supply pipe equipped with a backflow prevention check valve, and which generates hot water and powerlessly discharges the hot water through a discharge pipe. The powerless hot water pumping apparatus comprises an electric heater which generates heat when supplied with electric power; an upper cylinder which accommodates the electric heater therein, to the top of which the supply pipe is connected, wherein a steam generating space of a predetermined size is interposed between the inner surface of the upper cylinder and the electric heater; and a lower cylinder which is arranged beneath the upper cylinder, the top of which is in communication with the bottom of the upper cylinder through a connection passage, and to the bottom of the discharge pipe is connected. Hot water generated in the lower cylinder is automatically discharged by the steam pressure which is generated in the steam generating space of the upper cylinder by means of the heat generated by the electric heater.

A heat recovery installation using solar energy includes a three-channel plate, in which the first channel layer, viewed from the outside, alternately discharges used air and supplies fresh air. The third channel layer, viewed from the outside, ensures the supply of used air and the discharge of fresh air, while in the second channel layer, viewed from the outside, the heat exchange between the used and fresh air takes place according to the counterflow principle. In order to produce this flow, small apertures are provided in the second and third plates, viewed from the outside, of the three-channel plate, as a result of which the flow in the channel layer, viewed from the outside, is at right angles to the channel plate. By making the airflow quicker than the heat flow (Pe>>1), no heat can flow from the inside to the outside, except for a small loss flow through the partitions and through radiation and, conversely, mainly heat exchange of the used to fresh air according to the counterflow principle takes place with heat recovery. If the channel plate is made of transparent material and the inner plate is provided with a (sun)light absorber, then (sun)light which shines on the three-channel plate is also converted into heat and given off directly and indirectly to the fresh air.

A cogeneration system includes a gas engine generator acting as private power generating equipment for generating power to be supplied to private electricity consuming equipment, and a source-side heat exchanger connected to the gas engine generator through an exhaust heat recovery piping to act as a heat source. A heat medium is heated and evaporated through a heat exchange in the source-side heat exchanger. The resulting vapor is allowed to flow upward to be supplied to room heating heat exchangers. The vapor is liquefied through a heat exchange in the room heating heat exchangers. The resulting liquid is allowed to flow downward back to the source-side heat exchanger. This natural circulation of the heat medium is used for the heating purpose. Surplus exhaust heat is released through a generator to control the heat medium supplied to the room heating heat exchangers. Thus, the private power generating equipment supplies power to the private electricity consuming equipment, while exhaust heat of the generating equipment is used to heat rooms. The entire system is constructed at low cost.

A package heat exchange system using an expanded surface gas-fired burner to supply heat via a heat exchange coil in a dome above the extended surface heat exchanger which heats domestic hot water and supplies heat via the dome to a radiator for heating a living area of a home. A control system provides for utilizing steam from the extended surface heat exchanger to heat the coil in the dome and maintains a first pressure for supplying the domestic hot water and a higher pressure when radiator heat is called for. The heat for domestic hot water may be further heat transferred in a fourth heat exchanger which adjusts the temperature of the domestic hot water. The heat supplied to the radiator may be self-pumping by utilizing steam and the heat to the radiator may be cut off by supplying a control to the return pipe of the radiator which allows the radiator to fill with condensate from the steam.

The waste heat from a thermal power plant is transported through a municipal heating network to a plurality of buildings to be heated. The quantity of heat thus supplied to the buildings is higher than that required for the heating of the buildings. The excess heat is released from the buildings to the atmosphere in the form of hot air.
