While low-flow and high-efficiency fixtures top the list of water-conserving products going into today’s hospitality facilities, there has also been some interest in modular fixtures and instantaneous water heaters. At the same time, Markham claims that because hotel plumbing systems are generally centralized with high peak-hour demand, these systems are not necessarily the most efficient. “Instead, we’re looking at ways to recapture heat and hot water—for example, solar heat or lost heat from air-conditioning systems,” he explains.
