I am wondering about using this to pre-heat the water to an electric WH ? In series .
The reviews speak of poor Temp regulation ? The electric WH would act as a storage tank and , maybe even out the temp varations ?
By pre-heating the water entering the electric WH , I would think it would minimize the electric consumption ?
Set the output temp of the tankless to a hair below the temp settings of the tstats on the electric WH ? Or maybe slightly above ?
God bless
