This review is strictly for the manufacturer Rainlex, not Wayfair. I just spent 10k on a bathroom renovation only to find that this system doesn’t allow for hot water at all. I have tried repeatedly to contact someone in customer service for my plumber and the number is out of service and I’ve received no reply. I can’t even find any information about this manufacturer aside from their website that provides no assistance and their live chat function does not work. No one sells the parts for this system either. Save yourself from this experience and buy another brand.
