Its an interesting setup but honestly that will start leaking soon and I highly doubt it actually provides any heat.
where do you see it leaking?
i use special liquid and after ~2months i barely see clouding on the pipes
the loop is not closed, is at atmospheric pressure!
any heat? you must be very fun at parties!

the electric resistance heater on the boiler is rated at 2kw and 2*c1 is a bit under 1600w counting the aircooling done by the fan...
right now i have ~50C on asics and i almost can't keep my hands on the return to miner line from the boiler's serpentine
so there is 150liters of water at ~50c, not good enough for you?
