Re: My greenhouse is getting solar heating
With my greenhouse I'm not sure the water tanks really do all that much. Maybe yours will do more since your greenhouse is smaller (so your system is larger in relation to your greenhouse). I can't help but wonder if that small pump might use almost as much electricity as a small ceramic heater. You probably will need to run the pump 24 hours a day and the heater might be able to run only at night and many of them have a built in thermostat.
