which is a better heat exchanger for ng condensing boilers stainless steel or aluminum? I have heard aluminum is more prone to thermal shock which can crack the unit.

    love the TT's

    Nice. What if any recurring problems have you encountered? Ever use the Smart Indirect? what do you expect the life to be on the Prestige Solos if properly maintained? I just love the 'fire tube' stainless steel exchanger and the Smart Indirect - stainless tank in a tank - ingenious designs.
