A system of heating and water supply of the building


Oktopus Energy offers the latest technology in the field of energy saving – Octopus heat pumps of Swedish production.

The main ideology of Octopus was the creation of an economical heating system using alternative energy sources that maximally save natural resources and do not have a negative impact on the environment.

It is an efficient and environmentally friendly system of heating, hot water supply that transfers heat from the environment to your home.

OCTOPUS The modern air-water heat pump with a passive evaporator created by modern technologies does not require a fan  and freezes the evaporator.

OCTOPUS Designed for economic heating and hot water production in individual and multi-dwelling residential buildings, school and industrial buildings, sports halls and other premises.

OCTOPUS Easily combined with central heating.

OCTOPUS Allows you to reduce the cost of heating, compared with traditional systems by 70%.

The work of the Octopus heat pump is similar to that of an ordinary household refrigerator.

The heat pump pumps the heat scattered in the outside air into heat for the internal heating system of the object. To do this, on the street, near the building is installed evaporator, consisting of copper pipes, sharpened aluminum plates.

The evaporator with copper pipes is connected to the compressor-condenser unit located in the building, and is filled with a refrigerant.

Pressurized refrigerant enters the evaporator, where, due to a sharp decrease in pressure, evaporation occurs. In this case, the refrigerant takes away heat in the inner walls of the evaporator, and the evaporator in turn removes heat from the outside air, due to which condensation of moisture occurs in the form of frost or ice on the walls of the evaporator.

The compressor sucks from the evaporator a refrigerant, compresses it, due to which the refrigerant temperature rises, and pushes it into a condenser.

In a condenser, heated as a result of compression, the refrigerant gives the received heat to the heating system of the object and goes into a liquid state. The process is repeated again. When the desired temperature reaches the thermostat, the electric circuit breaks down and the compressor stops. When the temperature decreases in the object’s heating system, the process is repeated.
