The energy self-sufficient house

When the sun is shining, the photovoltaic system converts the free sunlight into electrical current – so-called direct current – with the help of solar cells. An alternator converts this direct current into alternating current, which can be used via power outlets to operate all kinds of domestic appliances such as a washing machine or stove or to charge an electric car in the garage. Alternating current can also be used to operate heating and air-conditioning devices such as electric radiators or residential ventilation systems.

The current is also used to operate the heat pump. This extracts heat from its environment, either from the ground, the water, or the air, and emits it again many times over as heating energy. At the same time, it consumes a small amount of electricity.

To ensure that the heat from the heat pump is used as efficiently as possible, it is recommended to combine the heat pump with underfloor heating. This only needs a low flow temperature. If retrofitting an underfloor heating is not practical in renovations, radiators can be installed that can also be operated with a heat pump.

The heat (energy) that is produced by a heat pump should also be storage-capable, since it is not always used immediately. This makes heat storage units an important additional component in every future-oriented system. These units are connected between the heat pump and the heating system (underfloor heating, radiator, convector), so that excess heat is stored for later use.

It is also advisable to purchase a storage battery (power storage system) for sunny days in order to conserve excess current. At night or on a very cloudy day, this supplies current to the power sockets again via the inverter. This allows a house to be self-sufficiently supplied with current and heat via renewable energies even if the sun is not shining.

The HVAC Division of Arbonia offers a large portion of the products for this environmentally friendly heating system. These include, among others, heat pumps and heat storage units, battery storage, underfloor heating, radiators, convectors, as well as ventilation units and air filters.
