I recently purchased two Nyle Therm dhw heat pumps from Tom in Maine. One them will be no problem to plumb. the other not so.. The one I am having trouble with is a smart 40 if you look at this link it shows a pic of the piping configuration on it . Has any one here plumbed a nyle to a smart 40.. Tom has suggested to plumb it to the boiler water side ,anyone on here have any alternative ideas that might work.
