The Ecodan QUHZ system combines a 4kW outdoor unit with a 200 litre Thermal Store and is the ideal

plug and play heating and hot water solution for properties with a low space heating requirement.

With very low market leading noise levels for its class and highly efficient hot water generation due to its unique

CO₂ system design, this compact space saving product is capable of providing instantaneous hot water and

QUHZ-W-VA

removes the risk of legionella.
