Solar water heaters use solar energyto heat water for a variety of uses, including home, businesses and industrial uses. Swimming pools heating, under-flooring heating, space heating or cooling are other possible uses of solar thermal energy. Solar hot water systems are composed of solar collectors, which collects energy from the sun. The heat collected is moved, through a fluid system, from the collectors to a storage tank and from there to the point of usage. The system may use electricity for pumping the fluid, or heat convection, depending on the type. The system may include also thermostats and a controller device to control the operation based on temperature differentials and hot water demand. In most cases a solar water heater can provide up to 85% of domestic hot water.

Induction cooking uses induction heating to directly heat a cooking vessel, as opposed to using heat transfer from electrical coils or burning gas as with a traditional cooking stove. To be used on an induction cooktop, a cooking vessel must be made of a ferromagnetic metal, or placed on an interface disk which enables non-induction cookware to be used on induction cooking surfaces. In an induction cooker, a coil of copper wire is placed underneath the cooking pot. An alternating electric current flows through the coil, which produces an oscillating magnetic field. This field induces an electric current in the pot. Current flowing in the metal pot produces resistive heating which heats the food. While the current is large, it is produced by a low voltage.
