A heating means installed in a pump for heating water during pumping has a tubular cylindrical holder that defines a heating chamber for the water. On the outside of the holder, a plurality of heating conductor tracks are connected together in series. The heating means is configured for operation of the pump in the horizontal state, such that its longitudinal axis extends horizontally. In this horizontal state, the heating means has a residual water level as a horizontal plane that lies roughly in the lower third. Apart from two heating conductor tracks, the heating conductor tracks extend below this residual water level, while said two heating conductor tracks extend above the residual water level. In the absence of cooling water on the inner surface of the heating chamber, they can overheat more quickly and be locally destroyed as an emergency safety device before the entire heating means is at risk of overheating.

A closed loop heating system for heating air of a given space includes a vacuum pump, a boiler, a heat exchanger, a blower, and a piping network. The vacuum pump maintains a low pressure in the piping network. The boiler is in fluid communication with the vacuum pump via the pumping network for heating a working fluid. The boiler heats the working fluid to a heated vapor. The heat exchanger is in fluid communication with the boiler for receiving the heated vapor via the piping network. The blower is positioned proximal to the heat exchanger for receiving air from the given space. The blower blows the received air over the heat exchanger for heating the air of the given space.

A low water cutoff switch controller features a dual inline package (DIP) in combination with low water cutoff switch processor. The dual inline package (DIP) has DIP switches, each DIP switch configured to set in a respective application type or mode corresponding to a particular water heater model for the low water cutoff switch controller to control, and also configured to provide DIP switch signaling containing information about a respective DIP switch set. The low water cutoff switch processor is configured to respond to the DIP switch signaling, and also configured to respond to corresponding signaling containing information about a sensed water level contained in the particular water heater model being controlled by the low water cutoff switch controller, and provide control signaling containing information to control the operation of the particular water heater model. The low water cutoff switch controller is a single controller that can be used for controlling any one of a plurality of different water heater models and have different voltage applications by setting a respective one of the DIP switches.

A water heater has a tank defining an interior volume, a heating element disposed within the interior volume, and a temperature sensor disposed with respect to the heating element so that the temperature sensor detects temperature of an area ambient to the heating element in the interior volume. The heating element is actuated at a predetermined actuation rate and for a cumulative actuation period so that the predetermined actuation rate maintains the heating element below a predetermined maximum temperature in air and so that the actuation period contributes a predetermined amount of energy to the ambient area when the heating element is immersed in water.

At least a part of said lower surface of said temperature monitoring and/or control unit is in thermal contact with at least a part of said upper surface of said carrier unit. Said lower surface of said temperature monitoring and/or control unit and said upper surface of said carrier unit are attached to each other by means of a welded seam, preferably by means of a laser-welded seam.

A method of controlling a heating system is provided that includes having at least one heater assembly, the heater assembly comprising a plurality of heater units, each heater unit defining at least one independently controlled heating zone, supplying power to each of the heater units through power conductors electrically connected to each of the independently controlled heating zones in each of the heater units, and modulating power supplied to each of the independently controlled heating zones. A voltage is selectively supplied to each of the independently controlled heating zones such that a reduced number of independently controlled heating zones receives the voltage at a time, or at least a subset of the independently controlled heating zones receive a reduced voltage at all times.

A water heater is provided which comprises a water storage tank made of enameled metal, an anode electrode (e.g. an anode rod) at least partly inside the water storage tank and a corrosion protection unit configured to impress current into the anode to provide a corrosion protection for the water storage tank.
