Experience with Rinnai vent-free convectors?
Anyone used or have experience with Rinnai Vent-Free Convectors?
I’m a little baffled by this product. No ducts, no vents, nearly 100% efficiency. Relatively low cost, relatively low total load. Am I missing something here? It seems like the low load crowd would be all over these, as a backup heating up for high efficiency minis if not as a main line unit.
