Heating is a topic most people would rather not think about. Radiators are ugly, expensive to run, and swapping them for something better sounds like a major building project. NOEMI, from the Czech company Elsymco, proves it doesn't have to be that way — no compromise on performance, design, or running costs.
Heat pumps are the future of heating — but only if you pair them with the right emitters. Classic radiators need a flow temperature of 60–70 °C to heat a room at all. A heat pump, meanwhile, runs most efficiently at around 35–45 °C. The result? Expensive running costs and disappointing performance.
NOEMI was designed exactly for that world. It heats effectively at a flow temperature of just 35 °C, letting your heat pump run in its optimal range while energy consumption drops. The same logic applies with a condensing gas boiler: the lower the flow temperature, the higher the boiler's efficiency. That one change alone can cut heating costs by up to 15%.
And that's not all. A classic radiator heats the air immediately around it — that warm air then rises by natural convection and settles near the ceiling. The temperature gap between floor and ceiling can reach 6 °C. NOEMI has an extremely quiet fan that actively distributes air across the whole room. Better heat distribution alone saves another 10% — with no change to the heat source at all.
NOEMI's fan draws less than 2 W and runs at the edge of audibility. That's not a marketing line — it's the patented EC motor technology Elsymco originally developed for high-end air-conditioning units. The result is a convector quieter than your own breathing.
And NOEMI isn't just for winter. Connect it to a heat pump and, come summer, it delivers dry, non-condensing cooling — no dripping, no dampness, no noise. Smart controls detect automatically whether the room needs heating or cooling and switch modes on their own. Year-round comfort from a single unit.
NOEMI wasn't born by modifying an ordinary radiator. It grew out of technology developed for air-conditioning units — which is exactly why it can heat, cool and move air quietly and precisely, not just "get hot."
Emitters are traditionally hidden away. NOEMI, by contrast, is meant to be seen. A perfectly flat front panel, seamless joints, minimalist lines — available in engineered stone or wood. NOEMI doesn't look like a radiator. It looks like a design choice you made on purpose.
It comes in 5 sizes and a wide range of finishes. Custom dimensions and surfaces can also be made to order, for anyone who wants an exact fit.
Replacing old steel or cast-iron radiators with NOEMI requires no major construction work. It mounts on wall brackets or under a window, right where the original radiator stood. A lower water volume in the system also means faster control response — and further savings.
NOEMI's cover comes off without tools, and the heat exchanger is easy to clean. No service technician, no complications — just a unit that stays good-looking and high-performing for its whole working life.
NOEMI is made by hand in the EU, from premium materials, with an emphasis on long service life and a minimal environmental footprint.
Want to heat more efficiently, more quietly, and with a result you're proud of? NOEMI is ready.
