It’s no secret that I think hydronic systems are terrific. That’s not to say that other hvac systems are inferior, it’s just that I’ve always been fascinated with hydronics — especially in-floor radiant systems. The few times I’ve been in homes that have radiant heat, I’ve always marveled at how comfortable they were. No cold pockets or stratification — just an even, warm feeling. Sitting on the floor in the middle of winter is even a warmer, cozier feeling.
But I’ve always wondered about the issue of proper ventilation with hydronic applications. These aren’t air systems, so what do people do to bring in fresh air? Too often, it seems as if no provision has been made for ventilation other than just opening a window.
