Heat Pump Heating Curve – What Is It?

2026-06-09

Heat pumps are devices that use thermal energy from the surrounding environment—water, ground, or air—to heat a building’s interior. They provide an environmentally friendly and energy-efficient way to ensure thermal comfort for occupants and, thanks to available subsidies, they do not necessarily have to be an expensive investment. Heat pump operation can be configured in several ways, including setting a fixed target temperature or linking performance to a heating curve. What exactly is a heat pump heating curve, and how should it be adjusted?

How to Reduce Heat Pump Cycling Through Proper Heating Curve Adjustment

Correct heating curve settings can significantly reduce heat pump cycling.

Cycling occurs when the device repeatedly turns on and off—sometimes even several times per hour. This behavior is highly inefficient and harmful because it accelerates component wear and shortens the system’s lifespan.

A properly operating heat pump should typically cycle only once or twice per hour.

By configuring the heating curve according to the building’s characteristics and the occupants’ comfort requirements, the frequency of start-up cycles can be reduced considerably. Achieving this should always be a key objective when optimizing system performance.

Heat Pumps and Available Funding Opportunities

Heat pumps are an excellent investment for companies planning to implement environmentally friendly energy solutions. Through programs such as Energia Plus, the Thermomodernization Bonus, or the BGK Eco Loan, financial support can cover up to 85% of eligible project costs.

Owners of single-family homes have even more funding opportunities available.

Non-renewable energy sources – what are they, what disadvantages do they have, and do they have a future?

Non-renewable, or so-called traditional, energy sources have for decades been the foundation of energy systems around the world. Coal, crude oil, and natural gas are resources that, despite the growing popularity of alternative energy sources, still play a key role in the energy systems of many countries. This situation makes the energy transition, which will help free the global economy from fossil fuels, increasingly urgent. So, what is worth knowing about non-renewable energy sources?

Cogeneration fee – what it is and how it affects your electricity bill

On your electricity bill, you’ll find many different charges. In addition to the amount for actual electricity consumption, customers also pay various distribution fees. Alongside the RES (renewable energy) fee, quality fee, capacity fee, and two types of network charges, there’s also the cogeneration fee. What is it, and how is it calculated?
