Energy efficient placement of mechanical room
Building a home in the Northeast, as I’m looking over the basement layout and options where to position the mechanicals – hot water heater – given the house design, from corner to corner on a diagonal, it is close to 150′. On one far end, the master bath and bedrooms on the second floor, on the opposite main floor, the kitchen, everyday living space and likely most used bathroom. So my concern is to get hot water to the faucet, from either of the two opposite ends, will require running the hot water for a period of time until all the cold water in the plumbing is flushed and it is filled with hot water which then will sit and cool, wasting energy, only to repeat the process with any demand of hot water. Have spoken to a few plumbers, use of instant hot for the area less utilized, circulating pumps, maximizing insulation of the tubing system, are the suggestions I have gotten. Was considering two mid sized water heaters in opposite locations rather than one centrally located main hot water heater. One said OK “whatever you say”, the other two didn’t seem to appreciate my concern for such minutiae. Is my concern unrealistic? Any constructive input/ideas are greatly appreciated.
