South Korea's Samsung has launched a new monobloc heat pump for residential use that can reportedly provide domestic hot water of up to 75 C when the outdoor temperature is between -10 C and 35 C.
“Sanitary water leaving a domestic hot water tank is 70 C when the outdoor temperature is -10 C and 43 C,” the manufacturer said, noting that the new product uses propane (R290) as the refrigerant. “Results may vary depending on the actual usage conditions.”
Samsung also said the new heat pump can replace old heating systems replacement in existing residential spaces that have been previously dependent on gas boilers for their heating needs.
The heat pump has a nominal power of 14 kW and a coefficient of performance of 5.0. It relies on an enlarged heat exchanger that the company claims is capable of transferring more heat compared to a conventional outdoor unit.
“Its heat transfer area is up to 39% larger,” Samsung stated. “As a result, it boasts a reliable heating performance, enabling it to deliver a 100% heating performance in temperatures as low as -10 C.“
It is also equipped with AI Energy Mode, a new function that adjusts domestic hot water temperature depending on a user's needs while reducing energy consumption. Its size is 1,270 mm x 1,018 mm x 530 mm.

Does this mean I don’t have to replace existing radiators with larger ones. What would be the cop rasing water temperature to 75 degrees to satisfy radiator temperature 🌡️? . This could be a simple straight swap for gas boiler . This might be the product that will sway me to change from using gas
@Alan, When I had my supplier come and do a survey they only suggested replacing two radiators with double thickness ones. Which I can do myself if I want. Have you had a survey to check if you do need anything changing?
Daft question time. I’m pretty sure it will still require a hot water tank but just want to check that with the larger heat exchanger it can’t supply hot water as needed?
Know its unlikely but if it has then this may finally allow me to take the plunge with a heat pump.
So will it produce water at 75C with a COP of 5 when it’s -10C outside, or will it only do it at a lower COP?
Sounds brilliant if true.
-10C is useless. I need -40C for a reliable heating system in Canada.
I don’t understand why people don’t install these in a basement or garage, where the Temps are significantly warmer than outside?
Because it is noisy and will freeze your interior space.
You need to read a bit more on how they actually work. They absorb heat from ambient air, which results in cold air coming from the exchanger. If you kept the unit in an enclosed environment, the ambient would get cold very quickly, resulting in continual defrost cycles resulting in no heat, but paying for electricity.
