Samsung announced the UK launch of the EHS Mono HT Quiet on 11 October 2022, describing it as the company's most advanced air source heat pump to date1. The unit will be available in the UK from the start of November in three capacities, 8, 12 and 14kW, with both single and three-phase power supply options, and all capacities sharing the same chassis2. It is the first model in Samsung's premium high temperature heat pump line up2.
The unit is designed to reach flow temperatures that conventional heat pumps do not. It can consistently provide hot water of up to 70°C for domestic heating purposes2, against the 40°C to 60°C range given for heat pumps generally2. The launch material states that many UK homes use radiators requiring hot water temperatures of 65°C or more to heat rooms effectively2. Samsung reports a seasonal coefficient of performance (SCOP) of A+++ for the model2, and says it was stress tested to provide 100% heating performance in weather as cold as -25°C2.
Noise is addressed through a double-layered sound insulation system that blocks and absorbs noise produced by system vibrations, with operation at noise levels as low as 35 d(BA), which secured Quiet Mark certification2. The unit is finished in dark grey and can be controlled remotely from a phone through Samsung SmartThings, allowing energy usage to be monitored daily, weekly and monthly2.
"With the Future Homes Standard requiring new build homes in the UK to be future proofed with low carbon heating by 2025, change is afoot and we're likely to see an acceleration in the switch from fossil fuel heating systems to more energy efficient heat pumps."
Samsung also cites UK heat pump market growth of 64% between 2020 and 20212. A later study shared by Samsung, reported on 1 December 2022, found that 78% of heating industry professionals said demand for heat pumps had increased in the last five years, seven out of ten saw heat pumps as more viable than a few years ago, and 79% said global issues were driving demand for such technologies3.

| Power supply | single and three-phase2 |
Why it matters for households
For homes with existing radiators sized for a gas boiler, the usual constraint on an air source heat pump is the flow temperature it can reach. Samsung's stated 70°C maximum is intended to remove the need to replace radiators in older properties, which the launch material identifies as a barrier to switching2. A higher flow temperature generally comes with a lower efficiency than a heat pump running at lower temperatures, but the sources do not give figures comparing running costs at 70°C with those at lower flow temperatures, and no installed performance data for UK homes has been reported. Noise is a common concern where a unit sits close to a neighbour or a bedroom window; the 35 d(BA) figure and Quiet Mark certification are the manufacturer's and certifier's claims rather than measured results from installations2. Remote monitoring through SmartThings gives a household visibility of its own electricity use, which is the starting point for judging whether a heat pump is cutting a home's exposure to gas prices. The sources do not state a price for the unit or for installation.
What happens next
The EHS Mono HT Quiet was due to go on sale in the UK from the start of November 2022 in the three capacities listed2. No further dates, including any wider rollout or successor models, have been reported.
