I get the problem--when you use too much 'draw' from the instant water heater, the pressure in the hot water supply drops and so if it's a pressure balancing shower, the volume drops as well. his solution is to pressurize the system. cool. that much of the theory I get. 

totally don't understand the schematic on the last page, though.

I agree - I understand the concept, because I deal with it in my shop 
bathroom that has a shower for the kids using the pool. When you set the 
water for the desired temp in the shower, using the hot water in the sink 
draws yells from the showerer - but I can't follow exactly how he is 
constructing a buffer to deal with heat production limitation.
