So I've been trying to build myself a HERMS setup for some time, with partial success, and want to put some questions to the group:
1) Originally, I only had 25 feet of 3/8 copper tubing for my heat exchange coil. Worked for keeping things at a certain temperature, but I just couldn't get it to work for raising the temperature in any reasonable amount of time. I tried, as an experiment, hooking up my pump (which I found out is one of the 1/50HP March pumps, not the 1/25HP) to the 50 feet of 3/8 I use for cooling, and I only got 1/2GPM. Slow. In peoples experience, is this rate too slow for use in HERMS setup? I'd really rather not have to buy any more copper if I don't have to.
2) If I do buy more copper, when people mention the 1/2 copper tubing, are they talking Type L (1/2 ID) or Refridgeration Type (1/2 OD, 3/8 ID). And would I need to get 50, or could I get by with 30 if it had much more surface area?
