	Spring is here, time to summarize thermal results. 1-2 kW Submersible hot water tank heaters corrode after about a month of use. They build up scale, and eventually the copper is eaten through. Ended up using 4x300W aquarium heaters to keep around 60F in the coldest times - coldest went down to about -10F outside. This is about $50 more in electricity per month (bill $100 total), but much easier than rilunninh stove. The other pond drops down to 38 without heat, so the remaining fish in there turned into fertilizer. South pond is fine.

			Spring is here, time to summarize thermal results. 1-2 kW Submersible hot water tank heaters corrode after about a month of use. They build up scale, and eventually the copper is eaten through. Ended up using 4x300W aquarium heaters to keep around 60F in the coldest times - coldest went down to about -10F outside. This is about $50 more in electricity per month (bill $100 total), but much easier than rilunninh stove. The other pond drops down to 38 without heat, so the remaining fish in there turned into fertilizer. South pond is fine.

			Microhouse goes below freezing in the mid of winter, and we can't use green house heat as is due to high humidity - so we need to do a heat exchanger so house wouldn't freeze if we just use solar thermal. There's plenty of heat, just not it's distribution. Sounds like a global issue.

			I let chickens in nto the aquaponic room, and Red fell in the water at 65F. I found her motionless floating in the water, she was stunned but warm. I put her in a hay box with a towel, and in the morning, she stiffened up. So we now have 3 of 4 chickens left, still laying eggs once in a while in winter. I am letting them out, but since we don't spend a lot of time in the microhouse experimental facility now, Catarina decided to move the chickens to the Seed Eco-Home.

	Pond 1 went down to 40 after coldest day. Pond 2 went down to 53. Pond 2 has 1 kW of heat. Turned on hydronic stove for backup heat. Microhouse Complex froze to about 29F. Within 1 week, 65 fish died over 4 days. First day - 5 fish harvested for food, as it was freeze kill. Later days fish didn't look as great. Largest fish was 13 inches. Composted in worm tower (started 2 weeks ago) and rest composted in chicken house soil beds. This is the second largest kill - first was leaving fill water on in the summer, 150 fish dead in both ponds as water spilled from one tot.he other. That is a disadvantage of ground level pond except for case of overspill. Learnings: automated refill and leak detection. Automated temp and parameter measurement with warning alarms. Passive heat via hillbilly would be sufficient, as only a small fraction of solar heat is captured into the water on sunny days. Maybe partial harvest for winter with only breeding stock left over. Partially buried ponds with wood framing for prevention of cave-in.		Pond 1 went down to 40 after coldest day. Pond 2 went down to 53. Pond 2 has 1 kW of heat.

	Optimal system would be a community Enterprise which generates clear exchangeable value. Part of conservatory space + combined heat power with hydronics, saturated water for night power, solar excess stored as heat both thermal and PV, Hillbilly heater, integrated with hydronics. Potential cooling with cold water in summer, but moisture issues must be resolved. Pellet stove, hydronic, with steam engine for CHP.

Heating is minimal - and I wonder if it is load mismatch since it's 560V open circuit DC, going into a 4500W 240V water heater heating element. There is some heat, but it certainly looks like it's not at the max power point - so getting a fraction of the energy. Temp is for example 61 if other pond is 59. Today it was 53 (cold and cloudy), while Pond 1 was 58 F with 1kW of power from 120V ac house grid power and 4500W 240 heat element. Note that debris accumulates on heater element rather quickly and probably loses 25-50% heating ability through the buildup - so it must be. Leaned daily.		Ponds without heat.
