There are some idea's I'm playing with.
Temperature here has dropped to a max of 30'C during the day so I can take the unit out of the loop.
I've noticed a couple of issues on my tank that need resolve:
1. Higher waterflow.
Currently a canister-filter is pulling all the load and that's simply too much.
2. The heat-exchange in the fridge of course.
Your Condenser could be a good option but eBay in Thailand? Nah,...then again, there's plenty of huge markets here where you can get virtually everything.
One improvement to both issues is to separate into two loops.
For the fridge, I want to get a separate pump and inlet/returns. That would help me to stimulate water-flow and reduce the load on the canister's pump.
On the heat-exchange, not sure yet.
- Condensor
- Very thin mantle, plastic hose/pipe
- Sealing the copper with a coating and have tank-water directly into it, like a sump.
Overall, the system works perfect after the last modification. Suits my needs to keep the temperature in 28-30'C range but I'm sure I can shave some more with one or more of a/m mods.
Will keep posting
