Rather than blowing air, I'd like to install a copper coil of 1/2" flexible copper tubing and heat water to pump through my in floor tubing in the basement. The question is, if I have 40' of 1/2" copper tubing in the chamber with water flowing through it at a rate of 1-3 gallons per minute (if I set my pump on low speed and only open 1 of 4 loops in the floor it is at 1 gpm, if I open the system up and set my pump on high speed it can push about 3 gpm) can I increase the water temperature from 60 F to 90 F?
I checked the temperature in the two chambers; during an average fire, the one closest to the firebox is at about 400F and the secondary one is at about 200F. The secondary chamber has better access for construction and would be preferred for use, but I don't think 200F is enough heat.
The system is set up so it flows into an open tank, so it intentionally isn't a closed loop system to avoid the chance of boiling waterm high pressure, expolosion, etc.
I'd appreciate an assistance in calculating if this might work, as well as any other suggestions for stripping the heat from the air and getting it to the water (i.e. radiator fins similar to hydronic base boards).
Thanks for any assistance!
