Hi guys and gals, really need some advice/pointers, please help:
Cold water storage is 2x50gallon tanks in series.
Hot water cylinder is 140 litres. (typical vented system)
Have a Crosswater mixer/diverter supplying the bath OR the shower. The shower is an overhead fixed "deluge" head type (ie no fancy pulsing/champagne flow etc). The manufacturers tell me that the mixer will pass 16 litres per minute at 1.2 bar and 22.5 litres per minute at 2.3 bar.
The pump will be either 1.2bar or 2.3bar from Techflow. Told that the 1.2 can supply at approx 16 to 18 litres a minute, the 2.3 at 21 to 22 litres per minute.
Here's the question: How quickly will each of these pumps empty the hot water tank (I think I'd like the 2.3 bar pump but am wary of it draining the Hot tank in 10 minutes).
Thanks very much,
Iain
