Introduction
Heat pumps transfer ambient heat and achieve efficiencies (COP) of 3–4, delivering three to four times more heat energy than the electrical energy they consume. Special heat pump electricity tariffs can further reduce operating expenses.
Heat Pump Types at a Glance
When selecting a heat pump, consider the COP (efficiency ratio), installation and running costs, space and noise requirements, and performance in your local climate.
Type | Heat Source | COP | Price Range (€) | Key Advantages |
Air‑to‑Water (ASHP) | Ambient air | 2.5–3.5 | 12,000–20,000 | Easy installation, lower upfront cost |
Ground‑Source (GSHP) | Ground/Soil | 3.0–4.0 | 25,000–30,000 | High, stable efficiency year‑round |
Monoblock | Ambient air | 2.5–3.5 | 12,000–20,000 | All‑in‑one unit, no refrigerant piping |
Domestic Hot Water (DHW) | Air & water | 2.0–3.0 | 10,000–15,000 | Dedicated hot water solution |
Top Heat Pump Brands & Price Tiers
The table below lists leading heat pump brands, their core specializations, and price tiers—helping you compare features and costs at a glance.
Brand | Specialisation | Price Tier |
ASHP, GSHP | Expensive (> 20,000 €) | |
GSHP, Ground‑Source | Expensive (> 25,000 €) | |
ASHP, Monoblock | Normal (~ 20,000 €) | |

Maintenance Tips
Filter Cleaning: At least once a year to maintain airflow.
Refrigerant Check: Technician inspection for leaks and charge level.
Hydraulic Systems: Bleed radiators and check system pressure.
Smart Controls: Verify operation of digital control units per EnWG § 14a.
