Frequently Asked Questions.
What is a monoblock heat pump, and how is it different from a split system?
A monoblock heat pump integrates all refrigeration components, including the heat exchanger and compressor, inside a single outdoor unit.
- Monoblock: No refrigerant piping indoors—only water pipes connect to the building’s heating or hot water system.
- Split System: Requires refrigerant lines between outdoor and indoor units.
Monoblock designs simplify installation and reduce the risk of refrigerant leaks indoors.
What applications are monoblock heat pumps suitable for?
They are ideal for:
- Underfloor heating
- Radiator heating
- Domestic hot water production
- Low-temperature cooling (in some models)
Common installations include houses, apartments, and small commercial buildings.
Are monoblock heat pumps energy-efficient?
Yes. They typically feature:
- High COP (Coefficient of Performance) values
- Inverter compressors for variable output
- Eco-friendly refrigerants (R32 or R410A)
Actual efficiency depends on the outdoor temperature and heating system design.
Can a monoblock heat pump provide heating and domestic hot water simultaneously?
Puremind many models support both space heating and domestic hot water production, either sequentially or with a buffer tank. Please refer to the product datasheet or consult our team for details on specific configurations.
