I note a float valve on the cold water supply. Would this system be pressurized? I'm not sure what the need is for a float valve in a pressurized, potentially constantly flowing system - it wouldn't deplete or overflow. Is the attic tank unpressurized, with just gravity flow to faucets?



Yes, it is an unpressurized system, gravity flow. The tank I'm planning to fit is a IBC insulated 1000 liters capacity. I was thinking about 1/2" pipe to heat the water slowly, since the heat exchanger shares the heat with the thermal mass. Even if the water heats in a week, that will not be a problem.



1 liter of water = 1kg = 2.2lb.   So you are going to put a literal ton of water in your attic... is your house made of steel? That's a lot of weight for ceiling joists to hold.
