Monobloc chiller heat pumps are among the most capable all-in-one systems available for residential heating and cooling. Every component sits in a single outdoor unit, eliminating the need for a separate indoor module and making installation straightforward compared to traditional split systems.
What is a monobloc chiller heat pump?
A monobloc chiller heat pump houses all its components in one compact outdoor unit. Unlike conventional split systems, no indoor unit is required. It produces both hot water for heating and chilled water for cooling, supplying hydronic distribution systems such as fan coils, underfloor heating, or low-temperature radiators.
Key benefits
- Versatility: a single system covering heating, cooling, and on many models domestic hot water production
- Simplified installation: all components in one outdoor unit
- High energy efficiency: strong COP and EER ratings, energy class A++ or above
- Compatibility with existing heating infrastructure
- Low noise levels compared to conventional systems
How does it work?
The system operates on a reverse refrigeration cycle. In heating mode, the heat pump extracts thermal energy from outdoor air, even at very low temperatures, and transfers it to the water in the hydronic circuit. In summer, the process reverses to chill the water for cooling.
Ideal applications
Monobloc chiller heat pumps are particularly well suited to:
- Properties with underfloor heating
- Buildings that already have fan coils
- Renovation projects replacing an ageing gas boiler
- Buildings aiming to cut CO2 emissions significantly
Efficiency and running costs
By drawing on renewable thermal energy from the air, monobloc chiller heat pumps can reduce energy consumption by up to 70% compared to conventional boiler systems. Depending on your location, they may also qualify for government incentives or grants supporting low-carbon heating.
