Can't keep a hps on 24/7 especially if I make it to flower phase also I don't trust hps lights both grows have hermed on me could be endless possibilities to why but I know them hps lights beam way too much heat

You need a reality check.
People have been growing with HPS for decades. So the idea it's the HPS fault your plants hermed and not poor genetics or poor environmental control is crazy.

Also, houses are generally at a reasonable temperature unless derelict.

Your also not considering that under HID- HPS , CMH or MH the grow room can be a fair degree lower temp for plants to be happy, as opposed to LED which we generally like to keep warmer.

Standard practice either way is lights off during warmest part of the day.

End of the day, if it costs more to keep a space warm using led then it defeats the purpose.

Wowsers cool Midwest I take it you your from the United States I'm from the United kingdom I'm worried about the cold air from the intake going into the grow space I mean how do you Control that? Also the water would be very cold.

Don't sweat it just make sure you supplement heat with a oil heater or something as with LEDs it's a must here in winter that or mix led with hid lighting anyway your not alone there is a big UK growers thread on here that might be worth looking at too

Summer/fall is best for me based on basement temps that time of year. I need to add a heater in the winter to an already over crowded tent.

Prevent it like this.

No chiller. DWC buckets roll from 71-67.
Build a panel for your tent. You reduce the tent part that you need to heat and cool by about 15%
