Heat Pumps – Everything You Need to Know

Costs, Efficiency, Benefits & What to Choose

Heat pumps are revolutionizing how we heat and cool our homes. By capturing free energy from the environment – from air, ground, or water – heat pumps can deliver up to 80% of heating energy by using only 20% electricity. They are efficient, eco-friendly, and help protect you from rising energy costs. At KRONOTERM, we combine over 50 years of European innovation with smart technology and award-winning design to deliver the most advanced heat pumps for homes and businesses.

How Do Heat Pumps Work?

Heat Pumps Extract Heat Energy From the Environment

‐

Heat pumps are one of the smartest and most efficient ways to heat and cool buildings today. Instead of generating heat by burning fuel, a heat pump moves heat from one place to another — using renewable energy available in the air, the ground, or water.

You can think of a heat pump like a reverse refrigerator:

A refrigerator removes heat from the inside and pushes it outside, keeping food cold.
A heat pump captures heat from the outside (even in the winter) and pushes it inside to warm your home. And in the summer, the system can reverse the process to cool your home, replacing an air conditioner.

The Heat Pump Cycle – Step by Step

Heat Capture (Evaporation):
The heat pump absorbs low-temperature heat from the environment (air, ground, or water) using a special fluid called refrigerant.
Heat Compression (Compression):
A compressor squeezes the refrigerant, increasing its temperature significantly — just like your hands get warm when you rub them together.
Heat Transfer (Condensation):
The hot refrigerant releases its heat into your home’s heating system (radiators, underfloor heating, or domestic hot water).
Pressure Reduction (Expansion):
After releasing heat, the refrigerant cools down and the cycle begins again.

Low Electricity Use for High Heating Putput

Imagine using just 1 kWh of electricity — about the same as running a hair dryer for half an hour. Thanks to KRONOTERM’s exceptional efficiency (SCOP of 5.20 or higher), that small amount of electricity can produce over 5.2 kWh of heating energy.

This is enough to keep a well-insulated 100 m² home warm for 1 to 3 hours, depending on outdoor temperatures — while using only a fraction of the energy that traditional heating systems would consume.

This is the power of a modern heat pump: small input, massive renewable output.

How Do Heat Pumps Capture Heat in Freezing Weather?

Even when the air feels cold to us, it still contains plenty of thermal energy. A heat pump uses a special refrigerant that can evaporate at extremely low temperatures — often below -30°C.

This means even at -20°C, a heat pump can absorb energy from the environment, compress it, and deliver warm, comfortable heating inside your home.

Overview of Heat Pump Types

Air-to-Water Heat Pump

Air-source heat pumps extract heat from the ambient air, even at temperatures as low as -20°C. They are versatile, cost-effective, and suitable for a wide range of properties.

Ideal For: Homes without access to ground or water sources, renovations, and new builds.

Ground-to-Water Heat Pump

Ground-source heat pumps harness the stable temperatures beneath the earth’s surface to provide efficient heating and cooling. They require the installation of ground loops or boreholes.

High Efficiency: Stable performance all year round regardless of outdoor air temperatures.
Low Operating Costs: Reduced energy consumption over time.
Long Lifespan: Durable systems with minimal maintenance.
Ideal For: Properties with sufficient land for ground loops or the ability to drill boreholes.
Require more installation effort, but deliver reliable, long-term energy savings.

Water-to-Water Heat Pump

Water-source heat pumps utilize the consistent temperatures of nearby water bodies, such as lakes, rivers, or groundwater, to provide heating and cooling. They are among the most efficient heat pump systems available.

Exceptional Efficiency: Stable water temperatures lead to high performance.
Space-Saving: No need for large outdoor units or extensive ground loops.
Properties located near a suitable water source with the necessary permissions for installation.
Installation with boreholes or collectors is more demanding, but efficiency and long-term savings make it worthwhile.

Benefits of Heat Pumps

Heat pumps are not just a trend — they are a smart investment in your comfort, savings, and the future of the planet. Here’s why more and more homeowners and businesses are switching to heat pumps:

Reduction in Heating Costs Due to High Efficiency – Up to 80% Lower Heating Costs

‐

Heat pumps don’t generate heat — they move it. That’s why they’re 3 to 5 times more efficient than oil or gas boilers. With a Seasonal Coefficient of Performance (SCOP) of up to 5.20 for air-to-water and 8.48 for water-to-water systems, KRONOTERM heat pumps are among the most efficient in Europe.

For every 1 kWh of electricity, you get up to 8.48 kWh of heat — drastically reducing your monthly energy bills.

Up to 70% Lower CO₂ Emissions – contributes to climate protection

By using renewable energy from the air, ground, or water, heat pumps produce zero on-site emissions and significantly reduce carbon output — up to 70% less CO₂ than fossil fuel heating.

Compared to an oil or gas boiler, a heat pump can reduce your home’s CO₂ emissions by up to 60–70%.
Switching to a KRONOTERM heat pump could save up to 3–5 tons of CO₂ per year for an average single-family home.

Over 10 years, that’s roughly the same positive climate impact as planting over 250 trees.

Switching to a heat pump is one of the most effective steps homeowners can take toward climate-neutral living.

Independence from Fossil Fuels

Oil and gas prices are rising — and their supply can be unstable.
A heat pump lets you break free from fossil fuel dependence and future-proofs your home against energy market fluctuations.

Heating with a heat pump means you’re using renewable energy (air, ground, or water) that’s free and abundant.
Pairing your heat pump with a solar power system can make you even more independent, using your own electricity to power your heating.

One System for Heating and Cooling

Modern heat pumps can do more than just heat. All KRONOTERM heat pumps can reverse the cycle in summer, acting like a highly efficient air conditioner. With passive or active cooling modes, you can enjoy year-round temperature control — with a single, integrated system.

Enjoy pleasant indoor temperatures all year round — without the need for a separate cooling system.
This feature is ideal for new builds and renovations where both heating and cooling comfort are important.

Lower Maintenance Effort than Traditional Heating Systems and Long Lifespan

Heat pumps are designed for long-term reliability and minimal maintenance — and KRONOTERM heat pumps take this even further with smart engineering and remote monitoring.

Unlike gas or oil boilers, which need frequent inspections, burner cleaning, and safety checks, a heat pump requires only one simple annual service. Maintenance usually includes cleaning air filters, checking pressure, and updating software — often possible remotely via CLOUD.KRONOTERM.

KRONOTERM units are developed and produced in Europe using high-quality components for lifespans of 20–30+ years, with ground systems (boreholes or collectors) lasting over 50 years. For comparison, traditional boilers often need replacing after just 12–15 years.

Over their lifetime, KRONOTERM heat pumps deliver significant savings — both in energy costs and maintenance expenses.
A typical household can save €20,000–30,000 or more over 20 years compared to oil or gas heating, making a heat pump not just a sustainable choice, but a smart financial investment too.
