There are many advantages to radiant heating and cooling, the chief among them being unparalleled comfort. Yet the hydronics market in the United States remains small compared to forced air heating and cooling. According to industry experts, there is still a market for this advanced technology. The global radiant heating and cooling systems market size is estimated to increase by $2.21 billion from 2021 to 2026, growing at a CAGR of 7.32%, according to a recent report from Technavio.
