Whether you have an older non-insulated family house with old radiators or you own an insulated office building with underfloor heating, a heat pump will certainly pay off. The most popular option for old houses is air-to-water heat pumps, mainly because the installation is fast and there is no need for earthwork. The investment in an air-to-water heat pump is also not too high. Thanks to the wide assortment of the PZP brand, it is quite easy for us to choose the right device for you.
The PZP assortment currently includes almost 100 models of heat pumps, only in the air-water segment PZP offers 4 model series (DYNAMIC, ECONOMIC, AMBIENT and SPLIT).

Heat pumps are an alternative energy source because they allow to remove heat from the environment (air, earth or water), convert it to a higher temperature level and then use it for heating or hot water. To transfer the heat to a higher temperature level, a certain amount of energy must be supplied.
The air-water heat pump is advantageous for use in all new and existing buildings where a flat collector or borehole cannot be realized (eg due to the requirement for a larger plot area). Stable heating capacity and high heating factor predetermine brine-water heat pumps for installation in colder (mountain) areas.
Nowadays, heat pumps are manufactured with maximum thermal and acoustic insulation, which will guarantee trouble-free silent operation and long product life. For example, in the case of ECONOMIC heat pumps, a lower air resistance was achieved and thus a noticeably reduced noise level was achieved by expanding the spacing of individual slats. Heat pumps today are therefore more efficient, economical and noticeably quieter. Prices of individual products can be found in our price list of heat pumps.

Like any other heat source, the heat pump is designed to cover the heat loss of the building. Heat losses are calculated according to specified criteria for a certain outdoor temperature.
When designing a heat pump, the following criteria must be respected:
To design the optimum heat pump performance, it is necessary to know:
Bivalent system
A heat pump is not the only heat source. It works in combination with a supplementary heat source - eg an electric boiler, gas boiler, oil boiler, etc. The heat pump is the basic and main heat source, which works throughout the heating period and the supplementary heat source completes the missing heating output for the necessary time.
Bivalence point
The outdoor air temperature at which the heat output of the heat pump is equal to the heat loss of the building. If the outside air temperature drops below this value, an additional heat source is connected to the heat pump.
For heat pumps, we recommend a regular service inspection, be it a heat pump for a single-family house or an apartment building. Regular service should be performed once a year.
Heat pump service is best done in summer. It is not necessary to heat the pump during this period, so it is used less frequently. During the service inspection it is also possible to adjust the heat pump settings according to real consumption and other parameters. This will make the operation of the plant even more efficient for the next heating season.
After heating, hot water is the largest financial item in the house's operating costs. Hot water heating by a heat pump is comfortable, maximally economical and environmentally friendly.
Any storage tank with sufficient heat exchange surface of the internal heat exchanger can be connected to the heat pump. The solution for year-round hot water heating is worthwhile with regard to the initial investment, especially in installations with higher daily consumption of hot water or in installations where the boiler with “auger” or other heat exchanger already exists.
For heating systems with PZP heat pumps we recommend a combined storage tank with a hot water heater. Rapid heating of hot water takes place in a spiral coil. The special shape of the pipeline ensures high heat transfer efficiency and at the same time eliminates sedimentation in the accumulation tank in hard water areas.
General features and advantages of use:
All of our products are backed by a service portfolio that enables us to maintain reliable and beneficial customer relationships throughout the life of the device.
The service life of a heat pump depends greatly on the quality of its key component - the compressor and all other components that are manufactured exclusively in Europe. A heat pump with the PZP mark will last at least 20 years without failure. We installed the first heat pumps back in 1995, so the service life of heat pumps has already been proven by practice.
PZP heat pumps already have a 5-year extended warranty for the entire heat pump already included in the basic price and without additional charges. This warranty covers, in the event of any defect in the heat pump, all repair costs, ie spare parts, service technician's work and transport costs.
Service and maintenance of heat pumps
We recommend a regular service inspection by a specialist on the heat pump.
Inspection should be performed at least every two years for the following reasons:
The decision to buy a heat pump made in a hasty manner within the time-limited "advantageous discounts" can significantly increase the cost! When purchasing any technical equipment it is good to ask several suppliers and compare their technical solutions and prices. This will take more time, but will significantly reduce the risk of buying, for a given purpose, an unsuitable or technically backward product. See the selected heat pump in operation. During the inspection, focus on the quality of workmanship, the noise of the heat pump and the experience of the owners with the work and service of the supplier.
The company PZP HEATING a.s. produces heat pumps of all three types. On the following lines we will compare their main advantages.
Advantages of the air-water heat pump:
Advantages of a brine-water heat pump:
Advantages of a water-water heat pump:
For the installation of a heat pump it is especially important to have a hot water heating system. If you have any radiators or underfloor heating, you have won.
For the heat pump to function properly, it is essential that the installed heating system is able to heat the building even with a lower heating water temperature. At the same time, the piping must be adapted for twice the flow of water than in conventional heating systems. Thus, a large volume of water in an older fin radiator system is a benefit, not a shortage. Just check if the size of the radiators is sufficient.
We will assess the heating system for you free of charge:
Yes, the choice of heat pump depends on local conditions. Ultimately, a hasty purchase decision can become significantly more expensive.
Therefore, before purchasing a pump, it is advisable to contact the heat pump supplier directly to compare the offers and information provided by each company. Owners of new buildings often make the mistake of leaving the choice of heat pump fully up to the construction company, which, however, does not solve the ideal heating system for the house. Therefore, we should not buy heat pumps for single-family homes in a hasty manner without sufficient information.

Perhaps the most common question asked by those interested in a heat pump is which type of heat pump they should buy. There are three basic types of heat pumps: air-water, brine-water and water-water.
Individual pump types have the following advantages:

The investment in the heat pump will return within a few years, usually in the range of 3 to 10 years, depending on the pump type, the energy performance of the heated building and the surrounding conditions. Price list of heat pumps for calculation of return on investment can be found on our website in section - price list.
