On "Diversified Heat Transfer Expands ST Series Semi-Instantaneous Water Heater Line with New High Output Double Wall Option"

Another incremental product refresh dressed up as innovation, but the real move here is that double wall tanks are now standard across the line instead of a premium option—that's actually worth noting for shops doing commercial work where you're already spec'ing DHT anyway. The "same footprint, more capacity" angle matters if you're retrofitting existing equipment rooms on tight jobs, but it doesn't change the fundamental economics or application mix for most plumbers. What you should care about is whether your suppliers are pushing this because DHT's margins improved or because your customers are actually asking for higher output in constrained spaces.
