The system implements a method in the installation, with the following steps: regulation is performed by placing the items of equipment in respective activation states chosen according to demand and parameters, for the purpose of optimizing with regard to criteria; at an intervention instant of regulation, regulation takes forecasts relating to at least one of the parameters into account, the forecasts relating to a period after the intervention instant. A related installation includes the regulation system.

Systems and methods for providing a personal heater are disclosed. In some embodiments, the personal heater comprises a housing, a heating element, and a controller. The housing is configured with an opening for receiving one or more feet. The controller is configured to cause the heating element to heat one or both of an interior and an exterior of the housing based on whether the one or more feet are inside the housing.

A water preconditioner system comprising a user interface for manually or automatically receiving inputs from a user, a mixing assembly including a plurality of control valves coupled to hot and cold water supply lines, and a controller in communication with the plurality of control valves and the user interface for controlling the operation of the system. The controller is configured to operate in a plurality of modes to precondition the water to one of a desired preset water dispensing temperature or a target temperature different from the desired preset water dispensing temperature.

The disclosed technology includes an on-demand water heater which uses an electric heat source to heat the water. The on-demand water heater can have a low fluid capacity heating chamber which has an inlet and an outlet, an electric heat source for heating the water, and a controller to control the electric heat source and maintain the temperature of the water at a predetermined temperature setting. The on-demand water heater can be powered by a direct current power source. The on-demand water heater can also utilize a solar thermal system to provide additional heat to the water.

A hot water supply system includes a hot water supply device which can be connected to an external communication network via a communication repeater, and a server. The server obtains, in pairing processing of associating a mobile terminal device which can remotely control the hot water supply device with the hot water supply device, identification information of a communication repeater to which the mobile terminal device is connected, and stores the identification information along with pairing information. Besides, the server performs control to determine conditions of the remote control based on whether the identification information of the communication repeater stored in association with the hot water supply device being a remote operation destination matches identification information of the communication repeater received from the mobile terminal device in the communication, when the communication of the remote control is received from the mobile terminal device.

Apparatus and methods for a gas furnace are disclosed. The gas furnace includes a variable combustion control which monitors the temperature of the burner and modifies one of the amount of combustion air supplied and the amount of gas fuel supplied to the mixing chamber. The described systems can dynamically accommodate differences in air quality and gas fuel supply to provide an optimum BTU output irrespective of differences in geographic location of usage. The gas furnace can include a dynamic response unit which predicts an optimum rate of heating to maintain a target room temperature, thereby preventing unnecessary shut down and costly re-ignition sequences, and maintaining the gas furnace at an optimum BTU output level.
