What is a high-temperature heat pump and how does it work?

A high-temperature heat pump is a modern heating device that transfers heat from a lower source to a heating system, enabling temperatures exceeding 65°C. This makes it an excellent choice for buildings requiring high supply temperatures. It can deliver water at temperatures ranging from 55 to even 80°C—for both central heating and sanitary use. One of the key factors influencing the efficiency of high-temperature heat pumps is EVI (Enhanced Vapor Injection) technology. This innovative solution enhances the device’s performance in low temperatures, which is particularly important in regions with harsh winters. EVI works by injecting vapor, increasing the refrigerant pressure and allowing higher supply temperatures. Importantly, high-temperature heat pumps can work with traditional radiators requiring water at 50-70°C. This makes modernizing older heating systems easier and more cost-effective. It’s also worth noting the COP (Coefficient of Performance), which indicates the device’s energy efficiency—the higher the value, the more economical the pump’s operation. Compared to low-temperature models, high-temperature heat pumps stand out with a broader operating temperature range and a different construction, enabling them to achieve higher temperatures. This is a key feature, especially when modernizing older buildings where maintaining high temperatures in the heating system is necessary. Choosing such a solution can significantly improve thermal comfort and lead to heating savings.

Who is a high-temperature heat pump suitable for?

A high-temperature heat pump is an ideal solution for owners of older buildings where existing heating systems require a high supply temperature. Thanks to its ability to generate heat comparable to traditional boilers, this device can efficiently work with classic radiators, eliminating the need for costly replacement of the entire installation. It’s also an excellent option for buildings with poor thermal insulation. In such cases, delivering water at higher temperatures is necessary to ensure thermal comfort. High-temperature heat pumps meet these requirements while improving the building’s energy efficiency and reducing heating costs. Before deciding to install a heat pump, it’s advisable to conduct an energy audit of the building. Such an analysis helps determine the actual heat demand and select the optimal heating solution. Additionally, the audit can identify areas requiring thermal modernization, further enhancing the system’s efficiency. Thermal modernization, such as wall insulation or window replacement, significantly improves a building’s energy balance. Combined with a high-temperature heat pump, such measures can yield real savings and enhance property comfort. Investing in a high-temperature heat pump is a step toward modern, eco-friendly solutions. It not only improves thermal comfort but also contributes to environmental protection.

Modernizing older buildings and the need for high supply temperatures

Older buildings often require heating systems capable of delivering a high supply temperature. In such cases, high-temperature heat pumps serve as a modern alternative to traditional boilers. They combine energy efficiency with ecological benefits, enabling heating system modernization without the need for costly replacement of the entire installation.

High-temperature vs. low-temperature—key differences

The choice between a low-temperature and a high-temperature heat pump is crucial for home heating efficiency. The main difference? The water temperature these devices generate. High-temperature heat pumps heat water to 55-80°C, making them ideal for traditional radiators. Meanwhile, low-temperature heat pumps deliver water at 30-40°C, making them perfect for underfloor heating in modern buildings. If you’re modernizing an older home, a high-temperature heat pump may be the best choice. Thanks to its ability to generate higher temperatures, it works well with classic radiators requiring water at 50-70°C. This avoids the costly replacement of the entire heating system—an important consideration when renovating older properties. On the other hand, low-temperature heat pumps work best in modern, well-insulated buildings. Their lower supply temperature pairs perfectly with underfloor heating, which operates most efficiently at 30-40°C. The result? Thermal comfort, lower bills, and more eco-friendly heating. When choosing, consider not only current needs but also future modernization plans. Is the existing installation compatible with modern technologies? Or does it require adjustments to fully leverage the heat pump’s potential? A well-thought-out decision ensures efficient and cost-effective heating for years.
