Hot water heater
I am upgrading my greenhouse from 11 x 16 to 13 x 22 and changing from single pane glass to polycarb. I have used a five gallon hot water tank to warm the water for watering my orchids. Unfortunately, the tank runs out of warm water soon after starting. I am considering removing the tank and just using water out of the tap. Our well water is about 52 degrees F year round. Any ideas?
