A standard hybrid heating and cooling system consists of a heat pump with a high COP / EER (conversion factor / energy efficiency ratio) and a properly dimensioned heating generator. Heat pumps use electricity to produce heat and cold, and the heating generator – gaseous, liquid fuel or woody biomass. The more renewable energy sources are used in a hybrid system, the more energy-efficient and environmentally friendly will be its work. The high annual savings potential is achieved as a result of their combined use.
In practice, hybrid heating systems using water as a heat carrier are very popular, with an air-to-water heat pump, a pellet boiler or natural gas for heat production and a piping distribution network to heat exchangers and heat energy consumers for heating and domestic hot water in separate rooms.
Thus, a standard system in which two sources of heating / cooling work are in fact a hybrid system. Heat pumps are a generally effective heating solution, while the ambient air temperature does not drop to around 0 ° C. This means that the heat pump unit produces heat that is cheaper than the energy generated by, for example, a gas boiler. When outside air temperatures fall below zero, the amount of heating gas required for the building goes much cheaper than the heat used in the heat pump. In this case, the electronic control switches off the heat pump and automatically switches on the gas boiler.

Another possible and practical solution is the supply of a hybrid system, including a heat pump and a biomass recovery facility, which can be used for heating pellet boilers and fireplaces, solar collectors, etc. These hybrid systems require higher investment costs than conventional systems, but the return on investment is within 3-5 years or even less, given the potential annual savings of 30-50%.

In other words, in case of positive external temperatures, the use of electricity for the operation of the heat pump is more economical, and in the case of low negative temperatures, the use of pellet boilers and gaseous fuel is more economical, providing much more stable heating at a rapid cooling .
The applications of the hybrid systems are varied. They can be installed in single-family and multi-family houses, apartments. A modern and practical solution in these objects is the heating and cooling of different rooms to be carried out differently, depending on the user’s desire: low temperature radiators, radiant floor, wall and ceiling heating or a fan coil system.
Similarly, hybrid systems can be used for heating and cooling of hotels, offices, restaurants, spa centers, warehouses, shops, workshops and more. It is important to note that hybrid systems have the advantage of being extremely versatile and allow even distribution of heating and cooling in the case of limited space.
Choosing a particular type of hybrid system will in all cases result in economic and environmental benefits across all seasons and variations in outdoor temperatures, a solution that will ensure guaranteed optimal energy efficiency and comfort for consumers throughout the year.
A hybrid system provides efficient heating and cooling with much lower operating costs than conventional heating and cooling systems at approximately the same efficiency. As a result of combining both energy sources, the hybrid system can optimize consumer spending as much as possible by automatically switching to a more cost-effective, weather-dependent source.
The heating and / or cooling modes, as well as the use of a given energy source for different seasons and outdoor temperatures, can be set by means of an intelligent control system that automatically monitors and monitors the system to ensure adequate and flexible work and optimal energy savings.
In geographically colder climates where outdoor air temperatures are below 20 ° C, gas or wood biomass heat pumps are not only the most efficient solution but also no alternative to guaranteeing the necessary thermal comfort. When the air temperatures rise and reach the preset levels, the heat pump will turn on and generate heating energy.
