Abstract: A hot water delivery system includes a water heater, a mixing valve that is coupled to the output of the water heater, and a plurality of loads that are coupled to the output of the mixing valve. A load set point temperature of each load that is representative of a maximum temperature of the hot water that is to be delivered to the respective load is set by a user. Responsive to detecting the occurrence of an event associated with a load of the plurality of loads, a controller of the water heater controls the mixing valve to adjust the temperature of the hot water from the water heater to the load set point temperature associated with the load, provided the load set point temperature of the load is different from a water heater set point temperature at which the water heater maintains the hot water therein.

Abstract: Controlling heating and cooling in a conditioned space utilizes a fluid circulating in a thermally conductive structure in fluid connection with a hydronic-to-air heat exchanger and a ground heat exchanger. Air is moved past the hydronic-to-air heat exchanger, the air having fresh air supply and stale air exhaust. Sensors located throughout the conditioned space send data to a controller. User input to the controller sets the desired set point temperature and humidity. Based upon the set point temperature and humidity and sensor data, the controller sends signals to various devices to manipulate the flow of the fluid and the air in order to achieve the desired set point temperature and humidity in the conditioned space. The temperature of the fluid is kept less than the dew point at the hydronic-to-air heat exchanger and the temperature of the fluid is kept greater than the dew point at the thermally conductive structure.

Abstract: The hot water supply apparatus includes a heat pump unit operating using electrical energy, a hot water storage tank storing hot water heated by the heat pump unit, and an auxiliary heat source device burning fuel and heating hot water when a stored hot water heat amount is insufficient for a heat amount used for hot water supply. A control device calculates a predicted heat amount for each unit time period based on a past usage record of hot water supply; estimates an error distribution of an actual heat amount relative to the predicted heat amount; calculates an expected value of loss in a target index using the estimated error distribution; obtains an optimal stored hot water heat amount minimizing the expected value; and controls the heat pump unit so that the hot water storage tank stores the optimal stored hot water heat amount.
