How do members have their on demand water heaters plumbed?

[spf8298]

How do some of you members have your on demand hot water heaters plumbed? Currently, I've got two Palomas that are plumbed in series and feed my 3 self serve bays. Is there any benefit to isolating the heaters and having one heater dedicated to the busiest bay, and having the other heater feed the other two bays?

I have one takagi demand water heater plumbed to my floor heat.
I have a second plumbed to an HTP superstor ultra indirect heater/tank, and all bays served from that HTP.

edit: I should probably mention that I keep the htp at around 140 degrees, and use a mixing valve to serve 100 degree water to the LP tanks and bays.

I do not heat any part of my touchfree washes. Before my upgrade I had one of my heaters fail. I ran like this for over a year one bay soap heat the other bay no heat. Never had a difference in wash quiality, and certainly never a complaint. I did not install them in my upgrade. I think it's a waste of money. Most of chemicals don't require heat and same with ro membranes.
Just an opinion.

What do you mean by the same with RO membranes?

You get a higher spot free production with warm water. I think 77 degrees is optimal.

So when I replaced the membranes in my spot free system I bought them as cold water membranes. I have noticed no difference since I cut out my hot water. So do you think my membranes will not last as long?

Supplying warmer water slightly increases the production but doesn't affect the membrane life.
