Triangle Tube guys, have you tried the instinct models yet?

Looks similar to the prestige solo, just has fewer pump controls. one labeled flame, one CH and one DHW

I think its set to do simple primary secondary loops as well as indirect DHW.

Big price difference though, the 155 model is 2000.00 compared to 4000.00 for the prestige.

I haven't,I got tired of the high price for parts and always changing models every couple of years. Moved on to the Lochinvar. Did talk with them about the instinct, sounds like they're on the right track unfortunately too late for me, at this time.
