Is anyone doing this? We recently purchased a beautiful new SS, insulated and jacketed 40 bbl HLT from La Breck Stainless.
We are using three Rinnai C199 199,000 btu/hr tankless heaters to heat the tank via a recirculation loop. The HLT is not pressurized, but vented to ambient air pressure. We're shooting for 185*F.
The performance is miserable. We're not getting anything like the projected 8-9 gpm per unit throughput. To heat 20 bbl of 60F water to 185 takes hours, when it should take about 1/2 hour or less.
Anyone with experience with these things--any brand or make? I'm beating my head against the wall.
