Connecting the output of solar hot water panels and a GSHP desuperheater to preheat domestic hot water?
I am installing both Enerworks solar thermal (hot water panels) and a Bosch GSHP (water to air) with desuperheater and am looking for advice on the best way to connect the two systems together to pre-heat/heat my domestic hot water.
Vendors of GSHP systems know how to plumb their de-superheater output to pre-heat DHW, as do the solar hot water panel vendors, but it seems to be an opinion rich environment when it comes to integrating both systems.
The house is in Northern New Brunswick, Canada. My reasoning for installing both systems is that the de-superheater will produce more preheat potential during the winter, and the solar system will be more productive in the summer.
Can anyone recommend the best way to connect these systems?
