In the face of rising prices of raw materials and energy, it is necessary to change the way of thinking about energy. Every source of heat from renewable energy should be taken into account not only when building a new house, but also when it is being thermally modernized. And what if the investor does not want to give up gas, but at the same time would like the installation to be more economical and ecological?
While in the case of new houses it is possible to design and build heating systems from scratch without any problems, in the case of older ones it is connected with the necessity of replacing the previously used heat source with a new one. In order to avoid a situation in which the house is insufficiently heated and to increase its energy security, hybrid heating is often used - says Kamil Rdzanek, expert at Immergas.
Immergas , with nearly 60 years of experience in the heating industry, offers Immergas Magis COMBO V2 hybrid heat pumps , which are a combination of a split heat pump with a gas boiler. This intelligent system selects a cheaper and more cost-effective energy source based on the settings entered. Thanks to the ability to use two heat sources, the hybrid heat pump is exceptionally economical and ecological. Based on the operating parameters entered by the user, it uses the source that is more cost-effective at a given time. This is especially important at a time when gas prices are rising, but we do not want to give it up. So if the investor already has a gas boiler and wants to replace it to heat cheaper, but does not want to completely give up gas heating, the hybrid heat pump is the ideal solution.

The existing gas installation will allow for easy connection of the internal unit without costly, labor-intensive modifications. The gas boiler supports the heat pump especially in extremely low temperatures, when the heat pump efficiency is lower. Thanks to this, the device provides thermal comfort to residents all year round, even on very frosty days. Hybrid heat pumps have an energy efficiency class of A+++ for a supply temperature of 35°C and A++ for a supply temperature of 55°C. A heat pump can generate over 5 times more heat energy than it consumes electricity, without emitting pollutants into the atmosphere. Heat pumps therefore guarantee heating of rooms and production of domestic hot water with a low share of electricity. This fact is confirmed by the COP coefficient, illustrating the ratio of heat energy generated by the heat pump to the electricity consumed by it. The highest energy efficiency class for heat pumps, high COP coefficient and use of air as an energy source mean that heat pumps are covered by co-financing under the Clean Air Program. Building owners who decide to install hybrid heat pumps can also take advantage of the thermal modernization relief. The tax deduction can be made when submitting a tax return for the year in which the device was purchased. It should be remembered that an invoice is required to document the incurred expense. The thermal modernization relief is up to PLN 53,000.
The hybrid heat pump successfully replaces other forms of heating. Thanks to advanced technology, it is able to operate at temperatures down to -25°C (applies to the operation of the heat pump). At such temperatures, it will both heat our home and provide constant access to domestic hot water. Due to the method of heating domestic hot water, Magis COMBO V2 is available in two versions:
- with a dual-function boiler (Magis COMBO V2),
- with a single-function boiler (Magis COMBO Plus V2) with the possibility of connecting an external domestic hot water tank
It is able to supply the installation with a medium at a temperature of up to 65°C when the heat pump is operating and up to 80°C when the gas boiler is operating. The Magis COMBO V2 system is not only heating and domestic hot water, using fan coils
or a surface installation, a hybrid heat pump can be a source of cooling for the building in the summer.
When should we recommend a traditional heat pump? It is worth considering such installation in new buildings where there is no gas connection. Gas supply is usually quite expensive and the installation of the pump itself will simply be cheaper. Heat pumps will also work well in buildings characterized by high thermal insulation, where heat losses are small. Investors are considering the installation of a heat pump, comparing its price to other heat sources, such as pellet boilers or eco-pea coal. Initially, the choice of the latter seems to be a cheaper solution. However, it should not be forgotten that the installation
a solid fuel boiler requires the construction of a chimney, which is not the cheapest investment. Such a boiler, usually quite large, must also be located in a boiler room of appropriate dimensions, and a place for storing fuel will be needed
appropriate room. If we add up the costs, it turns out that installing a pump is more profitable also because the pumps are maintenance-free and do not require additional involvement of investors.
In summary, when recommending a heating solution, the technical conditions of the building, the heat demand and the requirements of the residents should be taken into account. Particular attention should be paid to indirect costs, such as the costs of building a chimney or
boiler room, and not only on the price of the device itself. The warranty protection that the device is covered by is also important (let's pay attention to whether it is paid or not). Immergas heat pumps and hybrid heat pumps have a 5-year free warranty, which can be obtained after registering the device in the Immergas Customer Zone and on the condition of performing paid annual inspections.
