Seems recovery times and hot water usage is way off the mark here.
The following is a slight correction towards a previous post.............................
12 l/m @ 65c would use 6 l/m of hot water when mixed with incoming mains @ 10c.
(6 x 65) + (6 x 10) / 6 + 6 = 37.5c mixed temp @ shower head. (perfect)
6 litres x 20 min = 120 litres.
4 showers at 20 min = 480 litres.
Two 210 litre tanks with a coil rating of 20kw would take around 40 minutes to recover.
