Heat pump 9 kW
HEIKO heat pumps with a capacity of 9 kW are designed for buildings with higher heating demand. High performance, modern technology and energy efficiency ensure reliable heating comfort while helping optimize operating costs.
FAQ
Frequently Asked Questions
How do I choose the right HEIKO heat pump capacity for my home?
The required air source heat pump capacity depends on the building size and insulation standard. For newly built, well-insulated single-family homes, an average demand of 40–50 W/m² is typically assumed. This means a 100 m² home usually requires a 5–6 kW heat pump (e.g. HEIKO THERMAL 6), while a 150 m² property is generally suited to an 8–9 kW model (e.g. HEIKO THERMAL 9). For older or partially renovated buildings, heating demand may be higher, so the final selection should always be based on a professional heat load calculation (HLC) performed by an authorized installer.
Do HEIKO monobloc heat pumps perform well in very cold weather?
Yes. HEIKO THERMAL and HEIKO THERMAL Plus monobloc heat pumps are designed for reliable operation in harsh winter conditions and can operate efficiently at outdoor temperatures as low as -25°C.
This performance is achieved through:
- advanced inverter technology,
- high-efficiency DC compressors,
- an automatic evaporator defrosting system.
These features help maintain stable heating output, high energy efficiency, and reliable indoor comfort throughout the year.
What is the difference between the standard THERMAL heat pump and the THERMAL Plus version?
The main difference lies in the indoor hydraulic configuration.
The standard HEIKO THERMAL monobloc heat pump requires a separate hydraulic module installation. In contrast, HEIKO THERMAL Plus is an all-in-one heat pump solution, integrating both the hydraulic module and a 250-liter domestic hot water (DHW) tank within a single indoor unit enclosure. This design saves installation space, simplifies system integration, and speeds up installation.
Can a HEIKO air-to-water heat pump work with radiators?
Yes. HEIKO THERMAL air-to-water heat pumps are compatible with both underfloor heating systems and traditional radiators.
The units can deliver a flow temperature of up to 55°C, making them suitable for a wide range of heating installations. In addition, HEIKO THERMAL Plus models support two independent heating circuits as standard, allowing simultaneous operation of high-temperature radiator circuits and low-temperature underfloor heating systems.
