Split decision on hot water

摘要

Many homes have heating and air-conditioning systems that are divided into multiple zones, so why not zone the plumbing system? Zoning a heating and air-conditioning system allows homeowners to separately control, for example, the upstairs and downstairs temperatures to maximize efficiency. A hot water system also can be divided into multiple zones, but for different reasons.rnTwo Rinnai tankless water heaters will service the 2009 HGTV Dream Home in Sonoma, Calif. The two water heaters will reside in the attic to service two different sections of the house. Carefully spacing two units minimizes the physical distance hot water must travel to the end user. In other words, the closer the water heater is to the point of use, the faster users get hot water, says Bruce Lee, 2009 HGTV Dream Home builder.
