Description
The EHS Monobloc HT Quiet delivers whisper-quiet operation at just 35 dB(A), thanks to a four-stage hush mode and cutting-edge noise-dampening technologies.
Its outdoor module is wrapped in dual-layer acoustic insulation and the Groove Grid Felt design, soaking up vibration and component sounds before they escape.
High-temperature hot water
The EHS Monobloc R290 pushes domestic hot water to 75 °C, perfect for legacy radiator systems that demand temperatures above 65 °C.
It offers a future-proof swap for aging gas boilers in heritage homes.
Sustainable R290 refrigerant
With a GWP of only 3, the R290 refrigerant inside the EHS Monobloc R290 sits far below the European cap of 150.
Every component is tuned for R290, giving a greener alternative to mainstream R32 setups.
Smart control
SmartThings Energy tracks and fine-tunes power use, serving up automation tools that cut bills and edge the household toward net-zero.
Built-in hydraulic module
The outdoor unit houses an all-in-one hydraulic set—expansion vessel, circulation pump and flow meter—for a faster, cleaner install.
