In the face of rising prices of raw materials and energy, it is necessary to change the way we think about energy. Each renewable energy source should be taken into account not only when building a new house, but also when thermally modernizing it. What if the investor does not want to give up gas and 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 easily design and build heating systems from scratch, in the case of older houses it is necessary to replace the previously used heat source with a new one. 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, an Immergas expert.
Immergas , with nearly 60 years of experience in the heating industry, offers hybrid Immergas Magis COMBO V2 heat pumps , which are a combination of a split heat pump with a gas boiler. Based on the entered settings, this intelligent system selects a cheaper and more profitable energy source. Thanks to the possibility of using 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 profitable at a given moment. This is especially important at a time when gas prices are rising, and yet we do not want to give up on it. So if an investor already has a gas boiler and wants to replace it to heat more cheaply, but at the same time does not want to give up gas heating completely, a hybrid heat pump is the perfect solution.

The existing gas installation will allow you to easily connect the indoor unit without costly, time-consuming modifications. The gas boiler supports the operation of the heat pump, especially at extremely low temperatures, when the efficiency of the heat pump is lower. Thanks to this, the device ensures thermal comfort for 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 produce over 5 times more heat energy than it consumes electricity, without emitting pollutants into the atmosphere. Heat pumps therefore guarantee room heating and domestic hot water production with a low share of electricity. This fact is confirmed by the COP coefficient, which shows the ratio of the thermal energy produced by the heat pump to the electricity consumed by it. The highest energy efficiency class for heat pumps, high COP coefficient and the use of air as an energy source make heat pumps eligible for funding under the Clean Air Program. Building owners who decide to install hybrid heat pumps can also benefit from thermal modernization relief. A tax deduction can be made when submitting a tax return for the year in which the device was purchased. Please note that an invoice is required to document the expense incurred. The amount of the thermal modernization relief is up to PLN 53,000.
A 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 heat pump operation). At such temperatures, it will both heat our house and provide constant access to hot water. Due to the method of heating domestic hot water, Magis COMBO V2 is available in two versions:
- with a combi boiler (Magis COMBO V2),
- with a single-function boiler (Magis COMBO Plus V2) with the possibility of connecting an external hot water tank
It is able to supply the installation with a medium with a temperature of up to 65°C when operating a heat pump and up to 80°C when operating a gas boiler. The Magis COMBO V2 system is not only heating and domestic hot water using fan coil units
or surface installation, a hybrid heat pump can be a source of cooling for the building in the summer.
But when should we recommend a traditional heat pump? It is worth considering such installation in a new building where there is no gas connection. Supplying gas is usually quite expensive and installing the pump itself will simply be cheaper. Heat pumps can also be used successfully in buildings with high thermal insulation, where heat losses are low. Investors are considering installing a heat pump, comparing its price to other heat sources, such as pellet boilers or eco-pea coal. Initially, choosing the latter seems to be a cheaper solution. However, we should not forget that assembly
solid fuel boiler requires building 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 fuel storage will require
suitable room. If we add up the costs, it turns out that pump installation is more profitable also because the pumps are maintenance-free and do not require additional involvement of investors.
To sum up, when recommending a heating solution, you should take into account the technical conditions of the building, the heat demand and the requirements of the inhabitants. 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 coverage for the device is also important (please note 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 provided that paid annual inspections are performed.
